Citroen SIX-3.P3

[completelocks]

Hi guys.

never had this before. I am cutting and cloning a Berlingo key (SIX-3.P3 JMA) and i cannot get it to open any of the exterior locks. The original works fin obviously. The cut one works in the ignition, but I am completely stumped as to the doors, boot fuel cap.

Any advice?

I've had this before.

The reason was because I hadn't quite finished the cut off on the laser part of the key at the nose. Not all sides came to a point so it didn't go all the way in.

Maybe not your problem but worth a look.

on the laser part of the key at the nose

 

Huh, laser part.... this is a SX9 profile.

 

The customer's key is probably a remote key, and as such has not been used in a door lock for many years.

 

Best solution is to flush clean all perimiter locks with Winns Brake and Clutch cleaner, then lubricate well with GT85 or similar (Not WD40), work the key in and out of each lock & eventually they will/should all be functioning normally.

 

The key is fully inserted when only 3mm key blade is visible, if it shows 5mm, give key a little shove.

 

Tip: Always decode and cut to code for best results.

I don't have a cut to code machine so I cut sides on cylinder then top and bottom on Punto laser.

Is this unacceptable?

Depends on how worn the key being copied is!! and your cutting accuracy.

This door lock works differently to most other cylinder locks.

Most cylinder locks when the key is inserted, the cuts on the key moves the pins so they are flush with the shear line in the cylinder allowing the plug to turn whereas this lock it also allows the plug in its housing to move forward slightly so that the very tip of the key picks up a cam in the lock, therefore if the tip of the key is worn or the cam in the lock is worn or the key is not going in the lock far enough or the key is NOT CUT CORRECTLY then the lock will clutch instead of opening.

 

Strip the lock down and all will become obvious.

 

The reason why your ignition turns with the key is that it works on the principals of a normal cylinder lock so the tip of the key does not get involved.

Right. I need to get the original key back and look at the tip of the key. 

You learn something every day

In your situation where the customers key works I would be looking at your depths and / or spacing on the new key rather than the tip on the old key.

i decode these by eye and cut them on a silca 399 , still get problems on the doors ,usually down to the original being worn and where it is worn there is dirt within the lock replicating the rest of the worn key when it is inserted , a good flushing of the lock has always resulted with my key working after a few tries , unless i have of corse decoded the key wrongly lol

Have never had one cut on my 399 fail on the doors but i have on the ignition, usually the bottom of the lock is full of dust and debris, i use a small

broken key extractor to break it up then blow to remove it (remembering to close my eyes after one unfortunate incident).

I cut loads on 399 Evo I've never had the machine not cutting the key properly. I've read it wrong & don't work obviously.

 

I would look at calibrating the machine & cutter.
