Repair

Sometimes simply oiling the lock releases the pins and the lock becomes more effective. Often the lock is worn and needs replacement.

Method to remove

Inside door

• Remove window winder and door handle
• Remove armrest
• Carefully pull door card clips out of door frame
  • I use a flat screwdriver wrapped in tape to minimize the chance of scratching anything
• Wind window up
• Locate the two crosshead screws that secure the handle to the door
  • one is inside the door cavity, the other is in the door jam
• Remove door handle securing screws and carefully lift handle away from door

On your workbench

• Put key in lock and move to open position
• Carefully slacken the lock nut on the back of the handle
  • i.e the bit that was inside the door
• Unscrew the bolt the whole way then carefully re-insert it half a turn
• Gently push the barrel out of the door handle

Apply a light covering of grease to new barrel and push gently back into the handle.

Refit to the car (just reverse the steps above)
