Hi Allan.

 

Do you mean that the key won't open the car or won't start the car. If it won't open the car (or lock it) just use it in the door in the normal way, although you won't have the alarm as this is only activated when you use the "plip". These keys use a "rolling" code and if you or someone else has been messing with the key when it's out of range of the receiver in the car, the codes can become lost. The same applies to the spare key if it hasn't been used for a while.

 

Your key has a "Chip" in it which is read by a transponder in the steering column (Somewhere) when you insert the key into the ignition. The keys have to be paired to the transponder so that the immobiliser allows the car to start. This "pairing" may have become lost or confused. The battery in the key has nothing to do with this and is merely for the central locking and associated alarm function.

 

For both cases, as far as I know, the only thing for it is a visit to a dealer so that the pairing can be re-established.

 

Sorry can't be of more help :(

Colin, sorry I didnt get back to sooner, anyway my Xantia is an HDI and its a 2000 so from what I have gathered my key will be radio controlled so the story is that my remote key wouldnt activate the central locking, started the car ok, so I had a spare key which hadnt been used for a few years tried it and worked a couple of times and then stopped, I should have said that when my key didnt work I replaced the battery, some guys are saying that I have to reprogram the key but I am unsure how to do that, by the way thats not my only problem yesterday the heater blower runs cotiualy when the engine is running can you solce that one. Thanks Allan

Sorry I haven't been back tp you for a while. The weather has been FAR too nice for computerising! I think you'll have to get Citroen to reprogramme the keys. They shouldn't charge too much and if you ask them the procedure you may even be able to do it yourself.

As for the heater bloer, it sounds as if the resistor pack has failed. this is what makes the different speeds and if it fails it's flat out or nothing.

 

Cheers Hope this helps. :blink:

Thanks Colin, I cotacted Citroen Services in Rutherglen Glasgow about the keys and he wanted £40:00+ vat just to plug into the Computor so that was a no go Someone said that in car the hand book it explained what to do after replacing the battery in the key so I had a look, did what it said and it now works so thanks to all who got back to me on this, about the blower motor I am going on holiday on Friday so I will fix this when I come home. Thanks Again. Allan
