Drivers door won't lock.

[Toms_clio]

For sons reason my drivers door won't lock ! And parking in car park at work means anyone could just open the door and help themselves .
It won't lock with the key fob or the door lock button inside the car..
If anyone may know what part I need could you please link me it?
Thanks ..

Door solenoid posibbly sticking....

Take door card off so you can access the solenoid & door lock spray it up with some wd40 and then lock, unlock,lock, unlock a few times and that should solve problem
