Keyless entry unlock sensor

Need some help with my keyless entry. The sensor on my drivers door isnt working so i have to pull the handle to unlock it instead of it unlocking itself, if that make sense :huh: Now the sensor on my passenger door works fine and unlocks as it should so does anyone know if its possible to swap the sensors over so i have a working drivers door? I dont want to go and take both my doors apart and find out its not possible.

Just to add ive fitted a new handle to the drivers door so its not the handle thats the issue its the sensor in the door.
 
you need a rivet gun as well as the handsfree system is held on with one under the door handle :coffee:
