Hi All,

Just replaced the battery in my keyfob and the key now appears to be de-coded. Checked and replaced the battery to make sure it wasn't this. Looking on the internet a C3 forum said that to re-code the keys, I should turn the ignition to the 2nd position and hold the lock button down for 10 sec, then wait 1 min inside the car and then the key should work.

Does anyone know if this works for a C6? I don't want to stop my backup key working if this doesn't work.

Thanks,

Stew

(apologies if this has been asked before - I couldn't see a thread on it)

The question is if the blade is cut to fit the ignition, will these steps work To reprogram the key to the car:

- Key in ignition (ignition off)

- Turn key to ignition on, and press and hold locking button for about 5 secs.

- Release button on fob

- Turn ignition off

- Wait about 10-15secs and fob programming should be complete.

Yes, this procedure worked for me in the past.

Best regards,

4 years later and it still works this way if your key fob battery has died and been replaced.

Key in ignition, turn on, wait 5 seconds, turn off but leave key in place for 15 seconds before removing.

Worked for me today.

Sound advice that works effectively. Having the key fob re-programmed is another thing off the list. Now to establish why there's so much water in the spare wheel well in the boot... c'est la vie Citroen

Have a look at the rear light clusters, dirt can build up at the top end where the rubber section covers the gutter section, the car I bought recently had a blocked gutter, moisture in the light unit and water in the boot.



Removed the light cluster and cleaned everything before fitting a replacement unit and the boot now stays dry. Doesn't take long as there are only 2 wing nuts holding each one in place.
