Hi first Happy New year all. My peugeot cental locking doe not work. It does flash the lights when pressing the key but no door locks or unlocks but the tailgate makes a noise but is always locked. I have to remove the panel to unlock it but it locks again when shut. It does the same using the key in the door. I have removed the tailgate lock and it works fine with direct power. All fuses are fine. Any ideas please. Thanks in advance.

Check the door looms all of them as they can break and cause many weird things to happen, even greening of the wires can cause bad, weak signal.

I take it the door lock button on the dash does not work either (if it has one)?
If my information is correct, the doors and the tailgate are in separate looms, so its not likely to be that and you say you have checked all the fuses. The BSI is decoding the fob signal by flashing the indicators.
All the locks are run from the BSI. If past form is anything to go by, it's probably a dead relay in the BSI.
The BSI has 2 large printed circuit boards connected together with "fingers" that poke through the circuit boards. These are not soldered and have been known to fail as well.
If it turns out to be the BSI, there is no easy solution. There are solutions...but none of them easy.

Cheers, I will do a bit more checking and see what turns up.

How you getting on with the central locking ?

My 306 is in surgery at the moment having door looms checked/repaired.

Sounds familiar as in the last couple of weeks, my 206 1.4hdi also recently started doing a very similar thing, in that the indicators lit up, a definate click from the bsi (when checked on being sat in car) but neither door locking (3 door car).

In my case I suspected the boot locking motor wasn't working properly and subsequently unplugged it.

After putting the key in the ignition, starting the car briefly and retrying to lock the car everything worked (or it was just coincidence for me).

I ordered a replacement part off a famous auction site and it's all behaving currently. I don't have the lock button on the dash.

I do recollect soldering failed cables between the front doors and posts on a 306 as it was certainly common on mine.

Good luck hope you rectify it.
