Xantia RF remote immobiliser chip location

[RichardW]

Anybody know where the chip is in a MK2 Xantia remote? Is it in the blade, or in the fob housing somewhere? Trying to see if the ECU from my car could be fitted into Paul's without the key code (which I don't have....!).

Don't know for certain Richard, but I think it's moulded into the large chunk of plastic directly attached to the key blade and can't be removed from the key blade.

It might be easier to get the code for your car - I got mine a couple of years ago for under a tenner from the birdman, (as well as the radio code) and I'm pretty sure David Hallworth said that he got the code for the ECU's he swapped with me from Citroen Glasgow for no charge - as long as you present documents that prove you're the vehicle owner. So try giving them a call - can't hurt to ask!

Second hand / used Xantia keys CAN be reprogrammed for a different car / ECU's unlike the C5 - I've proven it with mine as my keys are now working with the CPH and engine ECU I got from David, I only required the 4 character code for the car the ECU's came out of. (VIN not required) So if both you and Paul have the codes for your cars you can swap ECU's (CPH required as well) and reprogram your existing keys with Lexia's and all will be well - no messing around trying to swap key blades or locks.

You could test the code you obtain works by attempting to reprogram your own keys before sending the ECU's away - if it lets you the code is valid. If the code is wrong it won't let you proceed to the programming stage with no harm done.

So is that your Xantia dead and off the road now or are you just doing an ECU swap with Paul ?

Ive seen I think on the Facebook Xantia Page that the Transponder Chip IS in the Key mould BUT it is possible to remove it from the blade plastic..

I tried to look for it last night but couldn't find the post.

Ive NOT got my Key Card code unfortunally, the onylway to do it is we send each other Our ECU's CPH AND matching keys that way it will work. A bit of an arse to do but saves getting key codes.

If it was me I'd still get the codes for the cars. Neither difficult or expensive. If you can get the code for free by turning up with the log book and ID then why not ?? If Citroen try to charge you more than a tenner try the Birdman. Then you have no mucking around with key transponders or swapping lock barrels and keys.

Out of swapping transponders or keys barrels and a quick Lexia session I know what I'd rather be doing! (And have done, as I swapped ECU's with David and simply reprogrammed the transponders AND RF remote in a couple of minutes - dead easy)

pictures of where the chip goes and how to swap. No need to reprogram chip just goes into new blank key and that goes into new fob. topfobs on ebay can supply next day.
