Yesterday the remote locking stopped working on our 406 mk2. Initially I thought it could be down to the keyfob having no buttons for a while.....
I got a new key this morning and swapped the internals so I had one with the buttons and went to try and re sync the key. I searched and found that I needed to press and hold the large button for 20s then press the small one, the light stayed on. Then went into the car and pressed large button one, switched on ignition for 10 s then off. Bloody remote locking still don't work.
All help & advice greatly received as both manual locks just spin so I can't lock the bloody car

Anyone know what might be wrong? I put it on PP2000 and it said there was a learning problem!!
