this is not a major problem but it bugs me quite a bit...

when using the keys to lock and unlock the door, there seems to be no problem. the power locks work perfectly.

the problem comes when im locking it manually (driver's side) when im inside the car. if i lock it, it locks all the doors, however the problem is when i unlock it, only the driver's side door locks.

is this some sort of electronic problem? i really dont think this is mechanical coz i have checked most of the moving parts already
