I have just changed out my fob for a replacement.
I bought an empty shell, and transferred the transponder and PCB across.
Obviously I now need to re-program it to unlock the car however...
I have tried all the various techniques found on the internet such as:
1) Place working key in ignition, switch on (without starting engine), close door, place new key into door lock and lock door (holding in the lock position for 10 secs). Release and press any key on remote, wait two secs and then press again, and then unlock the door with the key. Turn ignition off and it should be programmed - but it isn't!!!
2) Same as above, but don't hold key in lock position for 10 secs. Still doesn't work.
3) Turn key to unlock position and hold for ten secs - wait for pip from hooter - doesn't work.
Am I doing something wrong, or is there some other technique that I haven't found yet?
The remote was working before I swapped it over, and I'm 100% certain I've not damaged the PCB or anything like that (I'm used to working with delicate electronics). I have also checked that I'm getting the correct voltage (6v for this particular key).
Any other suggestions?
Also to add: The interior light (and red light in door) both come on when the door is opened (as does the headlamp warning buzzer if lights on) so that indicates to me that the door micro switch is ok.
So why can't I reprogram my fob? (that worked fine before changing it over).
Thanks in advance.
