Hi
Using a Lexia I programmed a key to match with the car central locking ECU. After that I can lock/unlock the car doors remotely. On the process of key programming I was asked to enter code that is written on a tag that comes with the car and it is attached to the key without the remote control and than press one of the buttons. After that the key was able to communicate remotely with the central locking ECU. I guess pressing the button transmits to the ECU the wireless code, then the ECU remembers it and from now on this key can remotely lock/unlock the doors.
In one of the steps Lexia asked key number ( it is not the code transmitted wirelessly ) and I enter "1" Can the central locking ECU communicate with more than one key , where each key has a different RF code ? I want to buy another key and programmed it as well and just wanted to make sure that the ECU can "remember" more than one RF code .
Thanks

Re: Xantia - Number of keys for central locking ECU ?
They usually have 2 keys.
Do you need the Lexia to program them? I remember the early models you just had to go through some convoluted process with the keys.

The Lexia can program more than one key, but any that are NOT used during the 'programming' phase will (for security reasons) be 'forgotten'. If you do decide to get more keys cut, you need to have them all to hand when you start a programing session.
