I'm new to this, so don't hold me to it but I read somewhere that any additional keys have to be coded within 25 or 30 seconds of the first one otherwise, after this time period elapses, the latest coded key takes over to the detriment of any earlier key.
My goddaughter just bought a 2007 TDV8 with one of her two keys only able to start the engine. When I see her next, I plan to use the procedure below, which I have cribbed from somewhere, to hopefully get the 'faulty' key to open the doors:
To do this procedure you need to have one working key and one key that
needs to be programmed.
1) Get in and close all doors.
2) Turn on the ignition and turn off quickly. (No more than 5 seconds)
to start the process. Next action must take place within 30 seconds.
3) Remove the 1st key.
4) Hold the key up near your left shoulder (this is so it is closer to
the remote receiver antenna.
5) Hold down the unlock button and press the lock button 3 times.
Release the unlock button and the doors lock which confirms the operation.
6) Quickly repeat steps 4 & 5 for key #2 etc. (ie within 25 seconds)
Turn ignition on and off to finalise
I take away from this that I will be programming the 'faulty' key and then have to re-program the good key immediately afterwards. The spare key seems only lightly used, so I am hoping there is not another reason it doesn't function.
