Re: Immobiliser Issue 406

no they cant!

Yes they can, Plug it in to the CORRECT Peugeot diagnostic machine & it can be reset.

The only time they CANT reset the code is when the keypad immobiliser has totally locked up because somebody has tried too many incorrect codes.

There is another way of resetting keypads, But its NOT for a public forum!

correct machine? think you have been misinformed but not gonna argue the point cos just cant be bothered End

Thanks very much;

That website is useful. I spent Friday phoning up the garage which was on the service history invoice, a peugeot dealer they guided me to, and the original dealer in London who sold the car. If I needed the radio code it would have been perfect because they all gave me that!

However, none could give me the code for the immobiliser. What was interesting though was that they all gave me completely different answers to my questions. They were all extremely helpful it has to be said, but the answers ranged from needing a new keypad at ?149 + VAt and then reprogramming (another ?60) to needing a complete ECU at ?600!! they all said that they could not find out the code if it had been changed from the factory setting, as the only person who knew this was the last owner. But one dealer said that could override the system using the diagnostics machine (not find the code but just switch the whole thing off?) But the other dealer said they could override the system only by removing the whole thing manually which would take 2.5 hours at ?80 an hour.

This left me somewhat confused. What I really don't understand is that it is just a circuit board carrying a signal like any keypad and if companies like the one you posted on your thread exist why can't peugeot just plug into the back of the keypad or ECU and let the machine read the code without the need for all the fuss, they must get phone calls all the time about the things especially looking at other threads on the topic.

Anyway, thanks very much, the good news is that I had written to the previous owner as a last resort not even knowing if it was the correct address. Well, this morning I got a phonecall from the owner who told me the code!!

Hi

Great news that you finally have the keypad code, Now you can change it, Use the service mode & turn the auto unlocking of the keypad by the remote plips on & off.

Thanks for your help. Much Appreciated

hi I have a 406 and the keypad is on 1111 is there anything I can do to a) change the code and b) get the immobiliser to go on/off with remote plips

thanks

Hi

To change to code follow these steps, Do these slowly, Dont rush.

Igntion on but dont start the engine.

Enter the old code & then press "C"

Enter a NEW 4 digit code & press "C" again.

4 Green flashes from the keypad & 4 beeps means the new codes accepted.

BUT: The keypad will for safety reasons remember BOTH codes untill the NEXT time the keypad is used.

Next time you go to start the car enter the code you wish to KEEP & the other code is erased out the memory.

To get the keyfobs to unlock the keypad for one minute follow these steps. If you dont have TWO keyfobs, Where it says press the second fob, Use the first one again.

Enter the 4 digit code on the key pad & then within 10 seconds press C C

Press the large button on the first remote ( 3 beeps )

Press the large button on the second remote ( 4 beeps )

Press C C again ( 5 beeps )

Lock the car with the remote, Unlock the car, Enter the 4 digit keypad code & then press C 1 C.

Next time you unlock with the remote the keypad should be unlocked for one minute only.

To switch this feature off enter the code & then C 0 C, To turn it back on enter the code & then C 1 C

Hi

I forgot to say, If you have the very early infra red type keys then you need to point the remote at the receiver in the roof consul. Just pop the key blade out from the remote fob & use some pliers to turn it in the ignition. If you have RF keyfobs you obviously dont need to aim the remote anywhere.

Also if you have a GLX, SRI or Executive on a N, P or early R plate then it also has a total closure feature built in.

Open all 4 electric windows, Deadlock the car with the remote, Big button first then within 3 seconds the small button & watch the windows shut themselves.

Is there any reason why the above might not work? I've tried it many times and although each step is confirmed with the right number of beeps, I still need the code every time :(

Ben.

Hi

After setting the key fobs up, You have turned the feature on?

Enter 4 digit keypad code & then C 1 C?
