Re-programing peugeot 207 key fob after battery change

SOURCE: fob wont work the locks

I have done this procedure for my peugeot 307, but you can give it a try for your Pug expert and let me know if it works.
Disconnect the battery for 5 minutes then after connecting the battery perform the following steps
1. Turn the Ignition switch to the ON position using your key.
2. Press the LOCK button for 10 seconds. It will set your ECU in programming mode.
3. Remove the key and wait for 10 seconds.
4. Press the buttons on the key repetedly for operation (lock und unlock doors) to synchronise the key signals.
5. Again turn the ignition on and start the engine.
6. Turn the ignition OFF

If fails in step 4, then disconnect the battery and reconnect it and wait about 10 minutes to check the remote. Some new ecu units synchronises itselfs if you disconnect the battery while in programiing mode.

Try this, press and hold the large button on your key fob,after 20 seconds press the small button while still pressing the large one, the led light will go out and will reset your remote. It worked for me. ray1297

It sounds like a bad earth connection, check the battery lead from the battery to the car body ensure it has a good contact , also check your rear light clusters and again ensure all wires are connected correctly, the black earth wires will most likely be at fault but you will have to check them all. there is one to the gearbox from the loom one from the battery to the the car body and another in the boot from the rear light clusters, also one on the back of the car radio. I would say its touching wires or a bad earth somewhere, also look around the fuse box especially the back of it.

Hope this helps
