406 Immobiliser problem

Hi all,

I'm hoping someone can help me out here because with it being Sunday no one
at Peugeot will answer the phone.

I have recently bought a 1996 406. The guy I bought it from forgot to give
me the immobiliser code. This wasn't a problem as the key is coded somehow
and as long as I start the engine quickly enough it works fine. The guy has
been out of the country but has now sent me the code. I thought I'd try it
out... I guess after the first failed attempt I shouldn't have bothered
trying it another 2 times... I'm not sure if he's given me the wrong code or
what but now it is beeping constantly and I can't start the engine?

Any ideas please?

Thanks,
Ben.

 

I left it for a while and it seems to have reset itself. It seems the code I
have is wrong or doesn't work. Would it be expensive to have it found
out/reset? I have no card or details of the immobiliser.

Cheers. At least I can start it now...

 

Ok Ben am I right in assuming you are talking of the immobiliser with the
number pad beneath the dash?
If so, I seem to recall it had an option to program it so that the code was
on the key
(effectivly defeating the whole point imo, but that's by the bye).
If you're starting it ok on the key, you are in the same situation as later
406
owners who don't have the pad to play with anyway.

If you're worried about only the key knowing the code, I believe certain key
cutters can read them,
so get a spare made(?)

 

Maybe it was the radio code that he sent you? Tell him what happened and
ask him again.

Thanks for the advice Jim, I'm not bothered about the key knowing the code.
The problem comes when the key stops working and I can't start it. Also, if
you don't start the engine within a minute or so the immobiliser comes back
on - meaning I have to lock it, wait, and unlock.

I'm guessing that if I had a spare made I would have to somehow get it coded
to the immobiliser...

 

I believe coded keys can be reproduced, that's what I was trying to say.
I like the other suggestion though if you do need to use the keypad.
The previous owner will be your simplest bet and may have thought you meant
the radio code.
There is also something like a maintenance code (see the handbook)
which is set when taking it in for service if you don't want em to know your
code.
He may have set it to that.
I never had it on the key on my old 406 so have no idea of time available to
start from key etc.

 

Hi Ben

You are obviously not receiving private emails. I can provide you with the
four digit workshop code for the 1997 406, which may or may not work on your
car.
Email me if you are interested.

My reply to address is a valid one, but I have sent you an email. If the
code works I'll be very happy. Seems shocking though that such a thing even
exists.

Thank you.

 

All you need to do here is, with the ignition on, press the large plip
button for a few seconds, while watching the engine management light
on the dash. It should flash a couple of times. Then you can start the
engine.

I wouldn't have thought key cutters could read the plip, which is
where the code is stored. The only way I know is to get a plip from
Peugeot (which can take five weeks as they come from France) and then
get your dealer to cut a key blank. They do not need coding to the
immobiliser when you get them as they already are. The dealer will
need to know the number from your key which is on a paper tag inside
the plip, to order it.
