Why doesn't key unlock or lock door?
I have a 1999 VW Jetta, the alarm fob does not work, so I manually open the driver's side door, since that is the only door with a keyhole. Today, I went to unlock the door, the key turns freely, but door does not lock or unlock. There isn't any resistance when I turn the key. Do I need to replace cylinder or complete lock. Also, my trunk will not unlock, I took it to my mechanic a few weeks ago and he fixed it, but now it no longer unlocks; the trunk lock has a lever in the car and that doesn't work either. When I turn the key in the trunk, I hear the mechanism but nothing happens. Any suggestions?
