First of all you need to generate into Silca Key blank a correct code , go to RW2 main menù :

ENTERING CODE->MEGAMOS 13 (if you read ID13 from original) [ENTER]

F9 0F A4 C1 2A 8D 8E 3B F9 0F A4 C1 2A 8D 8E 3B

or

ENTERING CODE->PHILIPS 33-73-40/45 (if you read ID33 from original) [ENTER]

FF FF F5 7E 0B FF 20 88 FF FF F5 7E 0B FF 20 88

 

then using Original Tester PGM , you need to learn the Silca key into a car

 

It is possible that using the Read key to start the Car the ECU will be damaged , but you can try

 

attacched you will find the honda service bulletin it explains exactly how to do in your situation

Service Bulletin 00-039

 

 

 

Applies To: 1997–01 Prelude – ALL

August 27, 2002

 

Immobilizer System (Type 1)

 

(Supersedes 00-039, dated August 29, 2000)

 

All 1997–01 Preludes have a Type 1 immobilizer

system that disables the vehicle unless a programmed

ignition key is used. A programmed ignition key is a

transponder-type key that has been cut to fit the

ignition switch and whose transponder ID code is

recognized by the immobilizer system. If you try to start

the engine without a programmed ignition key, the

engine will not crank.

 

This service bulletin covers

 

• Immobilizer system components

• Consequences of a lost key

• Rewriting the immobilizer control unit

• Adding ignition keys

• Deleting transponder codes of lost ignition keys

• Starting the engine without a programmed ignition key

• Replacing the immobilizer control unit

• Replacing the ECM

• Substituting a known-good ECM

• Customer situation and required items chart

 

 

WARRANTY CLAIM INFORMATION

 

None. This service bulletin is for information only.

 

IMMOBILIZER SYSTEM COMPONENTS

 

The immobilizer system includes the

 

• Immobilizer system keys (two master keys, one valet key, and one learning key)

• Immobilizer system indicator

• Immobilizer receiver

• Immobilizer control unit

• Engine control module (ECM)

 

Immobilizer System Keys

The vehicle comes with two master keys (black grip),

one valet key (gray grip), and one learning key (red

grip).

 

Each master and valet key has a transponder in its grip

that outputs an ID code when you insert the key into

the ignition switch. The immobilizer system uses this ID

code to determine whether to start the engine. There

are no batteries or other serviceable parts inside the

keys.

 

The learning key has a unique ID code that is matched

to the vehicle’s immobilizer control unit. It lets you

rewrite the immobilizer control unit to add programmed

ignition keys or to delete transponder codes of lost

ignition keys; it will not start the engine. If you try to

start the engine with the learning key, it may damage

the immobilizer control unit.

 

The learning key is given to the customer, sealed in its

plastic case. Advise your customer that the learning

key is a tool for the dealer; it is not for starting the

engine. Customers should keep the learning key

sealed in its plastic case and stored in a safe place.

Immobilizer System Indicator

The immobilizer system indicator is on the upper right

side of the instrument panel. When you insert a

programmed ignition key (master or valet) into the

ignition switch and turn the switch to ON (II), the

indicator comes on for 2 seconds. When you turn the

ignition switch to LOCK (0) and remove the key, the

indicator blinks for 5 seconds and then goes off.

If you insert a non-programmed key into the ignition

switch, the indicator comes on for 2 seconds when

you turn the switch to ON (II), and then it starts to blink.

It keeps blinking until you remove the key. If you try to

start the engine with a non-programmed key, the

engine will not crank.

Immobilizer Receiver

The immobilizer receiver is inside the bezel around the

ignition switch. It is powered by the immobilizer control

unit and uses electromagnetic induction to energize the

transponder in the key. The energized transponder

sends its ID code to the receiver, which then sends the

code to the control unit. The immobilizer receiver

contains no logic circuitry; it does not need to be

rewritten when replaced.

Immobilizer Control Unit

The immobilizer control unit is below the dashboard on

the left side of the steering column. It sends power to the

immobilizer receiver to energize the transponder in the

key. The control unit gets the transponder ID code from

the receiver, and checks it against the codes stored in

its memory. If the code matches, the control unit

energizes the starter cut relay and sends a unique serial

code to the ECM. But if the transponder ID code does

not match, no serial code is sent.

Engine Control Module (ECM)

The ECM is an integral part of the immobilizer system.

When the ECM gets the unique serial code from the

immobilizer control unit, it communicates or

“handshakes†with the control unit by sending back its

own unique serial code. If the serial codes are mutually

recognized during this handshaking process, the ECM

energizes the fuel supply system and the ignition

system so the engine will start.

CONSEQUENCES OF A LOST KEY

The programmed ignition keys and the learning key are

essential parts of the immobilizer system. If your

customer has lost one or both of these components,

the consequences could be costly. Here are some

typical situations you could encounter and the potential

consequences:

• Your customer has none of the programmed ignition

keys, but still has the learning key. The immobilizer

control unit must be replaced with the Immobilizer

Unit Set (P/N 04809-S30-A02, H/C 6316053).

• Your customer has none of the programmed ignition

keys and no learning key. The immobilizer control

unit must be replaced with the Immobilizer Unit Set

(P/N 04809-S30-A02, H/C 6316053).

• Your customer has a programmed ignition key but no

learning key. You have limited ability to add ignition

keys (you can only use the Silca Immobilizer Key

Code Duplicator), and you have no ability to delete

transponder codes of lost ignition keys from the

immobilizer control unit’s memory.

• You are replacing the ECM, and your customer has

a programmed ignition key but no learning key. You

need to also replace the immobilizer control unit.

 

REWRITING THE IMMOBILIZER CONTROL UNIT

The immobilizer control unit stores the ignition key

transponder codes in its memory. You must program

(rewrite) the immobilizer control unit with the PGM

Tester in these situations:

 

• Your customer wants an additional key(s), and the

Silca Immobilizer Key Code Duplicator is not

available.

• Your customer wants to prevent lost keys from

starting the vehicle.

• You replaced the immobilizer control unit.

Rewriting clears all transponder codes from the control

unit’s memory and then stores only the codes you

choose to enter.

 

Preparation

 

To rewrite the immobilizer control unit, you need these

items:

 

• The learning key

• All available programmed ignition keys (master and

valet) for the vehicle (This includes any T5 master or

valet keys.) If you do not have at least one

programmed ignition key, you must replace the

immobilizer control unit (see “The immobilizer control

unit is faulty†in the CUSTOMER SITUATION AND

REQUIRED ITEMS CHART).

• PGM Tester with SN300S or later software on an

8MB program card

NOTE: Make sure the batteries in the PGM Tester

are fully charged. Also, make sure the PGM Tester’s

setup [current date and time and market destination

(USA)] is correct before you use it.

 

•Password for the PGM Tester [Ask your service

manager for this five-character code, or get it from

the Interactive Network (iN) VIN Status Inquiry

display.]

Procedure

 

1. Gather up the learning key and all the available

programmed ignition keys for the vehicle. Set aside

any T5 key(s). The PGM Tester will not accept a

T5 key.

2. Stick a small piece of masking tape to the grip of

each ignition key. Mark them as “A,†“B,†etc.

3. Connect the PGM Tester to the 16P data link

connector.

4. Insert key “A†into the ignition switch, and turn the

switch to ON (II). Turn on the PGM Tester.

5. At the screen prompts, enter the VIN, the odometer

reading, and verify the correct date and time.

6. From the SYSTEM SELECT screen, select 5: IMMOBI.

7. From the TEST MODE MENU - IMM screen, select 3: REWRITING.

8. From the REWRITING MENU -IMM screen, select 1: IMMOBI. UNIT & ECM.

9. Follow the screen prompts. (You will need the

password for the PGM Tester here. If you do not

have the password, ask your service manager for it,

or get it from the iN Status Inquiry display.) The

PGM Tester eventually returns you to the

REWRITING MENU - IMM screen.

10. When you are finished, turn the ignition switch to

LOCK (0), then turn off and disconnect the PGM

Tester.

11. Start the engine with each ignition key. If any of the

keys do not start the engine, you must repeat steps

3 through 10 for all the keys.

12. T5 keys only: Start the engine with each of the T5

keys you set aside in step 1.

• If all of the T5 keys start the engine, the

transponder codes are already recognized by the

control unit. Go to step 13.

• If any of the T5 keys do not start the engine, use

the key code duplicator to recode those keys to

the code of a programmed ignition key (see S/B

99-053, Silca Immobilizer Key Code Duplicator,

found under Tools). Start the engine with each of

the recoded keys to make sure they work. Then

go to step 13.

13. Return the learning key to its plastic case, and give

it back to your customer along with all of the other

programmed ignition keys.

ADDING IGNITION KEYS

 

This vehicle originally comes with three programmed

ignition keys (two master keys and one valet key). The

immobilizer control unit can store as many as five

transponder codes in its memory. Use one of the

procedures below to add programmed ignition keys.

 

Silca Immobilizer Key Code Duplicator Method

 

If your customer wants an additional ignition key, use

the SILCA RW2/3/4 Immobilizer Key Code Duplicator with Silca

programmable key blanks .

The key code duplicator offers a low-cost, quick, and convenient way

to make a duplicate key from a programmed ignition

key (not RED KEY) . Refer to HON66T5 or NE77RT2, Silca Immobilizer Key Code

Duplicator, found under Tools, for details.

 

PGM Tester Method

 

If the key code duplicator is not available (only Red KEY Available), use the PGM

Tester with Honda key blanks instead.

 

 

 

 

Preparation

 

To add an ignition key with the PGM Tester Method,

you need these items:

 

• The learning key

• All available programmed ignition keys (master and

valet) for the vehicle (This includes any T5 master or

valet keys precoded .) The immobilizer control unit must be

rewritten to accept the transponder codes from all

available programmed ignition keys along with the

new key(s). If you do not have at least one

programmed ignition key, you must replace the

immobilizer control unit (see “The immobilizer control

unit is faulty†in the CUSTOMER SITUATION AND

REQUIRED ITEMS CHART).

• The vehicle’s key code for cutting new ignition keys

• Honda key blank (master), P/N 35113-S84-A01,

H/C 5435433

or

are fully charged. Also, make sure the PGM Tester’s

setup [current date and time and market destination

(USA)] is correct before you use it.

 

• Password for the PGM Tester (Ask your service

manager for this five-character code, or get it from

the iN VIN Status Inquiry display.)

Procedure

 

1. Use a Honda key blank and a suitable code key

cutter to cut a new ignition key (see S/B 88-012,

Cutting Keys With the Exacta Code Key Cutter,

found under Special Tools).

2. Gather up the learning key, the newly cut ignition

key(s), and all of the available programmed ignition

keys for the vehicle.

3. Stick a small piece of masking tape to the grip of

each programmed ignition key and each newly cut

key. Starting with the programmed ignition keys,

mark them as “A,†“B,†etc.

13. T5 Keys only: Start the engine with each of the T5

keys you set aside in step 2.

• If all of the T5 keys start the engine, the

transponder codes are already recognized by the

control unit. Go to step 14.

• If any of the T5 keys do not start the engine, use

the key code duplicator to recode the keys to the

code of a programmed ignition key (see S/B

99-053, Silca Immobilizer Key Code Duplicator,

found under Tools). Start the engine with each of

the recoded keys to make sure they work. Then

go to step 14.

14. Return the learning key to its plastic case, then give

it back to your customer along with all of the

programmed ignition keys.

DELETING TRANSPONDER CODES OF LOST

IGNITION KEYS

 

If your customer has lost programmed ignition keys,

you should rewrite the immobilizer control unit. This

clears all transponder codes from memory, thus

preventing the lost ignition keys from starting the

engine.

 

Preparation

 

To delete the transponder codes of lost ignition keys,

you need these items:

 

• The learning key

• All of your customer’s available programmed ignition

keys (master and valet, including coded T5 keys)

• PGM Tester with SN300S or later software on an

8MB program card

NOTE: Make sure the batteries in the PGM Tester

are fully charged. Also, make sure the PGM Tester’s

setup [current date and time and destination (USA)]

is correct before you use it.

 

• Password for the PGM Tester (Ask your service

manager for this five-character code, or get it from

the iN VIN Status Inquiry display.)

• Silca Immobilizer Key Code Duplicator (if T5 key

recoding is needed)

go to step 11.

11. Return the learning key to its plastic case, then give

it back to your customer along with all the

programmed ignition keys.

STARTING THE ENGINE WITHOUT A

PROGRAMMED IGNITION KEY

 

If your customer is stranded because he or she has no

programmed ignition keys or a part of the immobilizer

system has failed, you can still start the engine using a

properly cut key blank and either the Immobilizer Brake

Code Method or the PGM Tester Method.

 

Use the Immobilizer Brake Code Method if your

customer plans to drive the vehicle directly to a Honda

dealership for immobilizer system repair or he or she

has the other programmed ignition keys at home and

plans to drive there with no side trips. When you start

the engine with this method, you have a 10-minute

time limit between engine starts. If you exceed the

10-minute limit, you must repeat the entire procedure.

 

Use the PGM Tester Method if your customer does not

plan on visiting a Honda dealership right away or wants

 

to make several trips. When you use this method, the

engine can be started up to 50 times. After 50 starts,

the control unit must be rewritten with the PGM Tester.

 

Keep in mind that these methods are only a temporary

fix; when you start the engine, the immobilizer system

indicator comes on and stays on.

 

If your customer has no programmed ignition keys

currently available but has programmed ignition keys at

home, advise him or her to schedule an appointment to

have the immobilizer control unit rewritten for the

remaining ignition keys; this way the transponder

codes of the lost keys are cleared from the immobilizer

control unit’s memory. Refer to DELETING

TRANSPONDER CODES OF LOST IGNITION KEYS.

 

If your customer has lost all of the programmed ignition

keys, he or she will need to have the immobilizer

control unit replaced. Refer to REPLACING THE

IMMOBILIZER CONTROL UNIT.

 

Immobilizer Brake Code Method

 

Preparation

 

To start the engine with the Immobilizer Brake Code

Method, you need these items:

 

• Vehicle’s key code for cutting a new ignition key

• Non-transponder key blank, P/N 35117-SM4-901,

H/C 4225462

• Suitable code key cutter

• Immobilizer brake code (This code is available on

the iN VIN Status Inquiry display.)

Procedure

 

1.

Use a non-transponder key blank and a suitable

code key cutter to cut a temporary ignition key (see

S/B 88-012, Cutting Keys With the Exacta Code

Key Cutter, found under Special Tools).

2. Release the parking brake.

3. Insert the temporary key into the ignition switch.

4. Turn the ignition switch to ON (II).

5. Enter the first digit of the five-digit immobilizer

brake code by setting and releasing the parking

brake that number of times, within 30 seconds.

For example, if the first digit is four, set and release

the parking brake four times.

6. Turn the ignition switch to LOCK (0). (This enters

the digit into the immobilizer control unit.)

7. Repeat steps 4 through 6 to enter the second, third,

fourth, and fifth digits.

NOTE: While you enter the code, the immobilizer

system indicator stays on even when the ignition

switch is turned to LOCK (0).

 

 

8. After you enter the fifth digit, turn the ignition switch

to LOCK (0); the immobilizer system indicator does

three long blinks and then goes off. You can now

start the engine with the temporary key. Make sure

you start the engine within 10 minutes of

completing this procedure, or you must repeat the

entire procedure.

REPLACING THE IMMOBILIZER CONTROL UNIT

 

The immobilizer control unit must be replaced if it is

faulty, or if your customer has lost all of the

programmed ignition keys or the learning key. When

you replace the control unit, you must rewrite it with the

PGM Tester, or the engine will not start. The PGM

Tester stores the transponder codes from the

programmed ignition keys, transfers the codes to the

new control unit’s memory, and instructs the control

unit and the ECM to recognize the other’s unique serial

code.

 

Preparation

 

To replace the immobilizer control unit, you need these

items:

 

• Immobilizer Unit Set, P/N 04809-S30-A02, H/C

6316053 (Kit contains an immobilizer control unit, a

master key blank, a valet key blank, and a learning

key blank.)

• All of the programmed ignition keys (master and

valet) for the vehicle, including any coded T5 keys

• The vehicle’s key code for cutting new ignition keys

• Suitable code key cutter

are fully charged. Also, make sure the PGM Tester’s

setup [current date and time and destination (USA)]

is correct before you use it.

 

• Password for the PGM Tester (Ask your service

manager for this five-character code, or get it from

the iN VIN Status Inquiry display.)

• Silca Immobilizer Key Code Duplicator (if T5 key

recoding is needed)

Procedure

 

1. Replace the immobilizer control unit. Refer to the

Body Electrical section of the 1997–99 Prelude

Service Manual.

2. Use a suitable code key cutter to cut the master,

valet, and learning keys that come in the kit. Refer

to S/B 88-012, Cutting Keys With the Exacta Code

Key Cutter, found under Special Tools.

3. Gather up all of the programmed ignition keys

(master and valet) for the vehicle. Set any T5 keys

aside.

4. Connect the PGM Tester to the 16P data link

connector.

5. Insert the master key you cut from the kit into the

ignition switch, and turn the ignition switch to ON

(II). Turn on the PGM Tester.

6. At the screen prompts, enter the VIN, the odometer

reading, and verify the correct date and time.

8. From the TEST MODE MENU - IMM screen, select 3: REPLACE IMM UNIT.

9. Follow the screen prompts on the PGM Tester.

Make sure you use the learning key that comes

with the new control unit. Save the learning key

from the old control unit for warranty purposes.

When the process is complete, turn the ignition

switch to LOCK (0), then turn off and disconnect

the PGM Tester.

NOTE: When the PGM Tester refers to “originalâ€

keys, it means the keys that come with the new

control unit. The keys that came with the old control

unit are now “new†keys. To become programmed

ignition keys, you must add their transponder codes

to the new control unit’s memory.

 

10. Start the engine with each of the programmed

ignition keys to make sure the immobilizer control

unit was properly rewritten.

11. T5 Keys only: Start the engine with each of the T5

keys you set aside in step 3.

• If all of the T5 keys start the engine, the

transponder codes are already recognized by the

control unit. Go to step 12.

• If any of the T5 keys do not start the engine, use

the key code duplicator to recode those keys to

the code of a programmed ignition key (see S/B

99-053, Silca Immobilizer Key Code Duplicator,

found under Tools). Start the engine with each of

the recoded keys to make sure they work. Then

go to step 12.

12. Return the learning key to its plastic case, then give

it back to your customer along with all of the

programmed ignition keys.

REPLACING THE ECM

 

When you replace the ECM, you must also rewrite it

with the PGM Tester. This instructs the new ECM and

the immobilizer control unit to recognize each other’s

unique serial code. If you fail to rewrite the new ECM,

the engine will not start.

 

Preparation

 

To replace the ECM, you need these items:

 

• Replacement ECM

• Programmed ignition key (master or valet) for the

vehicle

• PGM Tester with SN300S or later software on an

8MB program card

NOTE: Make sure the batteries in the PGM Tester

are fully charged. Also, make sure the PGM Tester’s

setup [current date and time and market destination

(USA)] is correct before you use it.

 

• Password for the PGM Tester (Ask your service

manager for this five-character code, or get it from

the iN VIN Status Inquiry display.)

Procedure

 

1. Replace the ECM. Refer to the Fuel and Emissions

section of the 1997–99 Prelude Service Manual.

2. Connect the PGM Tester to the 16P data link

connector.

3. Insert a programmed ignition key into the ignition

switch, and turn the ignition switch to ON (II). Turn

on the PGM Tester.

4. At the screen prompts, enter the VIN, the odometer

reading, and verify the correct date and time.

5. From the SYSTEM SELECT screen, select 5: IMMOBI.

6. From the TEST MODE MENU - IMM screen, select 3: REWRITING.

7. From the REWRITING MENU -IMM screen, select 2: ECM.

8. Follow the screen prompts on the PGM Tester.

(During the procedure, you will need to enter the

password for the PGM Tester. If you do not have

this password, ask your service manager for it, or

get it from the iN VIN Status Inquiry display.)

9. When you are finished, turn the ignition switch to

LOCK (0), then turn off and disconnect the PGM

Tester.

10. Start the engine with the programmed ignition key

to make sure the immobilizer system was properly

rewritten.

SUBSTITUTING A KNOWN-GOOD ECM

 

Do this procedure if you need to use a known-good

ECM to test a vehicle. You can swap an ECM from a

donor vehicle without having to rewrite it to the vehicle

you are working on.

 

1. Use a non-transponder key blank, P/N 35117-SM4901,

H/C 4225462, and a suitable code key cutter

to cut a temporary ignition key for the vehicle you

are working on. Refer to S/B 88-012, Cutting Keys

With the Exacta Code Key Cutter, found under

Special Tools.

2. Remove the ECM and the immobilizer control unit

from the vehicle you are working on. Write the VIN

on the ECM and the control unit to avoid confusing

them with the known-good parts from the donor

vehicle.

3. Remove the known-good ECM and immobilizer

control unit from the donor vehicle, and install them

in the vehicle you are working on.

4. Tape the donor vehicle’s ignition key grip-to-grip to

the temporary ignition key. The control unit will

recognize the transponder code from the donor

vehicle’s key, letting you start the engine with the

temporary key.

5. Do the needed tests on the vehicle you are working

on.

6. When you are finished, reinstall both ECMs and

immobilizer control units, and destroy the

temporary key.

Good info NPXT.

 

Fast Fix Elgin, So how you getting on with the Civic?

 

I'd say the immo will be corrupt & new immo module will be needed, but if it is still good it could be sorted via EEPROM (Electrically Erasable Programmable Read-Only Memory) application.

Out off my hands now TeL200

 

customer went to the dealer so dont know the outcome.....hope he got it sorted.

It's this sort off job that puts me off the idea of investing £000s of pounds and hours of learning just to piss of a customer,

 

Thanks to you all
