Central locking problem

Hello to all

Am facing the above problem
I install an e bay central locking mechanism. my car already have but with out remote
Everything works fine until 4 days ago.
The problem is ... when i unlock the car with the remote control only the drivers side door unlock.
And the most strange of all... when i get in the car and close the door suddenly all the other 3 doors unlock!
I guess the vibration when the door close makes the mechanism to unlock the other 3 doors
When i try to unlock the car with my key all doors unlock together.
I spray some wd40 to the key hole but no luck..
Please someone to help me ??
Thanks
