I have a Peugeot 206 manual model 2004. I have a problem with my remote key. I can open my car, but can't lock the door once I press the unlock. I heard a sound click for unlock and directly return, open all the doors. How do I fix this problem?
Double check to ensure all of the doors are closed, as well as the trunk (boot) and hood (bonnet) of the vehicle. Just one of these things being ajar or if the sensors for these are broken (won't register), the doors won't lock. Since they unlock, it shows the system itself is working (car is acknowledging the fob request).
