The battery in my Peugeot 306 key was dead so I have replaced it and I followed the instructions to turn the engine off, and on, then press the button etc, but it still doesnt work.

Any ideas why it wouldnt be working still?

306 PLIP RE-SYNCHING (For RF models only)

For late RF model keys if your remote should stop working (due to changing the battery or pressing the remote too many times out of range) you can try re-synchronising it by doing the following (note - must be original fob supplied with vehicle):

1.Switch off the ignition

2. Switch on the ignition

3. Immediately after switching on the ignition, press the large remote button

4. The remote should now be working again.
