I have recently bought a 307 second hand. However the spare key remote locking does not work. It will start the car but wont open the doors etc.
I went out to a shop and bought a new battery and tried the reprogram feature, but it still dont work. The technique I tried is :-
1) Put non working key in ignition.
2) Turn ignition on (2 clicks)
3) Turn off ignition
4) Turn on ignition
5) press lock button for 10 secs
6) release lock button and turn off ignition
7) try key
8) nothing happens.
Is this technique right? Also if this key is duff. Can I just buy another key from ebay for example and reprogram that?
