Land Rover Repair: 2002 Land Rover Discovery 2 SD-back door lock, land rover discovery 2, land rover discovery

Question
Hi
I am a new owner of a Land Rover Discovery 2 SD 2002 model and I have noticed the very back door lock is having problems locking and unlocking when I use the remote on it. As there is no keyhole in the back door, the only way I am able to open it after it is locked is to climb over the back seats and open it from the inside with the latch. I really need to fix this problem asap as my wife is needing to use the back hatch for a trip coming up.
Any and all advice you may have as to what may be causing this problem would be greatly appreciated.
I have tried reversing the safety lock switch in the inside of the door as well as manually locking and unlocking the door but neither seem to help.
Thanks for your time.
Sincerely
Charles

Answer
Almost always this problem is a lack of lubrication.  Pop off the Land Rover logo oval on the handle and spraypenetrating oil into the mechanism.  Spray in the latch hole too.  After several applications your problem should go away.  If it does not, you'll have to remove the door panel for lubrication access.
