HELP!!

[StevenB]

Had a customer in last week with a yale key to be cut (YAX1, new yale 5 pin).

I cut him the 12 that he asked for - and he came back the next day to say that none of them worked.

 

There's a small notch on the bottom of his original, roughly beneath the shoulder & he reckoned that as this wasn't there on the ones I'd cut, that's why they didn't work.

I filed notches on them all & guess what - they still didn't work.

 

So today he brought the lock cylinder in so I could have a look - and I just can't get them to work.

 

Has anybody else experienced problems with these, or do you have any ideas as to what I can try next?

 

I've checked my machine for alignment & it's absolutely spot on.

Measuring the original key & the ones I've cut with a vernier gauge, they are the same (to the nearest 0.1mm).

Originally I cut onto YAX1 blanks, I've also tried 1A without success.

 

I've also cut a key for a brand new lock off the shelf as a test (a Grundmann euro cylinder with 62GE key) and it worked perfectly first time.

 

I'm thinking it might be a rogue cylinder but don't know how to test / prove it!

 

All advice welcomed, as ever...

Have had a few problems with HD blanks but the JMA blanks come with the notches as standard and I have had no trouble with these

We have had the same problems,infact we have had 2 back today they seem to need to be

cut slightly deeper than the original key.Not exactly sure of the measurement but about 85 thousandths

of an inch seemed to do the trick for us.

 

Once you have got one working you can duplicate this as normal.

 

Yale cylinders have been going down the tubes for a long time and we no longer stock them anymore,

the problem will more than likely be with the cylinder plug as we have not had any problems with

cutting yale keys untill this year and they are all the new cylinders causing the problems.

 

Had to key alike three cylinders last week and even though i have genuine yale pins they still didn't seem

to work very well so i ended up using some of my universal coloured pins from the oem pinning kit,that seemed

to do the job.

yes hold by flutes as an experiment in case blank is mis formed

[StevenB]

turn jaws around and hold key in the bottom flute

 

yes hold by flutes as an experiment in case blank is mis formed

 

I clamped the keys by the flutes as suggested, it took a little more off & hey presto they worked!

Oh the power of the forum. I was close to giving up on this one.

Thanks guys.

I used to spend hours taking about 25thou of the back of yale keys - then cut new keys for cylinders - no other key cutter could make them work unless they used the flutes

wot a crafty old git I was.......

 

So glad the solution worked

[kirkybob]

so thats what you do under your table Mick, sit there filing the back of keys. I will try your trick next time thanks mick.

[Mick Friend]

if you prepare one blank then reverse it in the key machine and run the blanks through reversed of course

Say no more...
