Powered Lock - UnLock Door Problem

[Joval]

Hi,
When I want to lock or unlock the doors It seems that the electrical power is not enough or something is wrong with the lock-unlock system because most of the time I do have to do it with the key. I does not matter if I try with the remote control or with the switches located in the doors, the system does not lock or unlock the doors.

Is there any part I need to change, or something is requiered to be cleanned at the doors ?


Any clue?

Thanks
Jorge
