removing keypad immobiliser

Post by wirdip »

Hi folks,
I have a 1996 806 SRDT with keypad, is it much of a job to remove this and is it a good idea to do so.

Normally, and it seems to hold on most, is that you can disconnect the keypad with the engine running and then you'll never need it again. This is the case with most 1.9TD engined PSA vehicles although I cannot guarantee it'll work for sure on your 806. Noting lost in giving it a try...

But why? They're pretty trouble-free and I can't see any difficulty in having to enter a four digit PIN before you can fire it up. Two of my cars have keypads in working order but then they both have the only PSA engine I know for sure that the keypad cannot be disconnected...

Unless you have a very good reason then I'd leave the keypad in place and in working order.

Because the keys wear out in time and leave you stranded :wink:

Well, change the PIN regularly so the keys get even wear then :wink:

You'd be amazed Jim. Only last night I was dealing with a Doctor who manages to lock her network account out every single week because she screws the password up. Intelligent lady, obviously. Not great at remembering things.

hi, its pretty easy to remove keypad. turn ignition on and enter pin number into keypad until green light comes on on the keypad. once this is done remove keypad cluster using small screw driver and you will see a multi-plug connector in the back of the keypad. unclip this and your keypad is disabled. its pretty simple to do but please be aware your vehicle is no longer secure once youve done this. :)

Indeed it is but...

For anyone thinking of doing this, there is one exception where it won't work - that is on the 2.0TCT engine with the Bosch MP3.2 Injection. An engine commonly found in Xantia Activas and many XMs along with some Pug 406s...

I am not aware of any other exceptions but would urge caution around 2.1 Diesels with the Lucas EPIC pump as I have no knowledge as to whether or not the keypad can be disconnected in the manner Keith describes...

Thanks to all you large brained contributors for your help. Nice to know that I have sparked such a lively thread. Just as a matter of fact is this procedure reversible????

Yes it is Alan, so long as you can remember the last PIN used before disconnecting the keypad...

I would guess those still connected must have been the good ones. From what I remember they were anything but trouble free in the early days and disconnecting was almost standard procedure.

I can remember the early days too. They would not work / refuse code / display both lights, then you'd come back an hour later and they'd be fine. I suspect it was corrosion on the IC1 connectors the large round ones at the front on 106's and 406's that were some of the cause, although S1 306's the wiring seemed to on some models appear to corrode from within. To be fair the newer shape did not do that as much.

Am interested to know about the two models that refuse to have said keypads disconnected. Jim, have you set them to be in "auto" mode, ie green light for 30 seconds automatically when using plip method ? If that does not work then I have to suspect these models have something going on in the CPH unit to prevent it...
