Hello everyone, my car is a 2006 model 1.4 diesel 206. I bought it new. When I lock it with the remote control, the locks unlock as well as close. When I lock it on the road at low speeds, it closes and unlocks. I can only lock the car with the key. When I lock it from the passenger door, all of them lock. When I lock and unlock it from the driver's door, only the driver's door opens. Can anyone who has experienced this before help me? Thanks in advance.
