Hi there I recently purchased a C3 used car. The problem is if I try to unlock or lock the car using the keyhole on the driver side it just unlocks/locks the driver side. its not a problem unlocking the car as when I get inside the car I can unlock all the other doors with the button on the dashboard. The problem is locking the doors I've tried locking the doors using the button on the dashboard with the drivers door open it just double click. Then with the drivers door closed locks fine then when opening the drivers door unlocks all the doors. I took to the garage where I purchased the car they said thats the way the car is and to use the switch on the side of each door and the boot will not open. Is this the case?
