Hi all,
I tried to lock my '00 Xantia today, but it wouldn't and the button didn't click either. So I took key apart and the button for it has come off the circuit board. Fairly easy to spot that fault then.
However, my spare key hasn't had a battery in it for some time, and won't unlock/lock the car when I transfer the battery across. My local Citroën place want to charge £35 to get it 'retuned'. Any ideas how I go about recoding it myself?
Another thing: either key in the ignition allows the car to start, but I thought it should be immobilised with the long-dead key. Does the immobiliser not rely on the key having power, or is there some problem going on there as well?

The immobiliser does not need power, I believe it works off an induction loop in (or near) the ignition barrel.
I have resoldered the switches succesfully with a fine soldering iron and a steady hand.
Reprogramming the system is done by switching on the ignition then pressing the buttons on the 'plip'. I can't remember the exact sequence but a search on the forum should come up with something. £35 to retune it is really extracting the urine since the job takes seconds, in fact they could just do the decent thing and tell you how to do it over the 'phone.
Not sure how much a bettery costs but you could pop into the dealer with the pretence of buying a bettery and then have a chat with the assistant?
