Program Xantia mk2 Radio key

Post by skog77 » 26 Aug 2014, 18:36

Hello!

I have just aquired my second Xantia after the ECU on my first one died. This one is a mk2 1999 with beautiful leather interior, PMB and fun gadgets like a rain sensor.

However, the plip key does not work. The previous owner put in the wrong battery, then decided he'd rather use the spare key as it took up less space in his pocket..

I've now changed to the correct battery, but it still does not work. Unlike my old Xantia with an IR key, this is a two-button radio key. There is no radio key card in the car.

1. Is the key supposed to have a LED light up when i press the button? I can't find any LED light anywhere.

2. My friend has a Lexia. Can we do anything with that?

1, There is no LED for an S2 Xantia keyfob control.
2, You don't need the Lexia. According to my Xantia handbook all you need to do is to switch on the ignition, and then operate the remote control.

Hm, i tried doing that right now.

Switch on the ignition and press the opener. Also held it down for a while, but no reaction.

Perhaps the key is dead :?

I would check the soldering of the buttons inside the fob - the joints are notorious for cracking - one of the buttons on my previous S2 fob had completely fallen off and was rattling around inside! :lol:

If you have access to a Lexia and have the 4 character confidential code for the car, I would attempt a key/fob programming session to see if it can be correctly programmed.

The re-syncing procedure mentioned above only cures problems where the rolling code has got out of sync (usually caused by a battery left flat for a long time, or pressing the buttons more than 25 times while out of range of the car) but won't help if the fob and ECU aren't paired.

It could be that someone swapped the circuit board inside the fob or the fob itself to replace a faulty one, or the CPH ECU/Engine ECU were swapped in the past and they didn't know how to reprogram the fob.

At least a Lexia session will tell you if the fob is transmitting any signal at all - as it will accept and respond to ANY S2 Xantia fob during the programming process.

If it doesn't detect anything during the programming process its a fair bet that the fob is faulty. You can program any second hand Xantia S2 fob to the car using a Lexia, so you could get hold of one from a scrappy, swap the boards between fobs then program it with the Lexia.

The most likely scenario is the fob circuit board is faulty or is not the original one from the car.

I hooked up my mates Lexia, and it gave a fault code about a faulty key. However i do not have the four digit code, so i couldnt do anything more.

I'll try and get a hold of that code.

Two ways, either go to your local Citroen dealer with your VIN and proof of ownership or else see if the bloke on here from Ireland (his name escapes me) can still supply the codes..

He'll do the CPH code, radio code and all key codes.

I called up a dealer and explained the situation, expecting to be asked to show up with ID and everything.

He just jotted down my phone number and emailed France, he'll call back with the code when he gets it :-D

Excellent :-D

Others have suffered the Spanish Inquisition before the dealer has done the necessary!

Yes but you know what people say about the Spanish Inquisition.

Got the code, used the Lexia, and they key now works again!

It was good to get this done, as i have some bad experiences with the norwegian winter and frozen Xantia door locks. Not quality items :)

Next mission: Re-align the exhaust system, because the previous owner had it fitted so that the muffler touches the rear bumper when going up hill. #-o
