I had a similar problem with my son's 1998 Jetta K2 4 door. I sprayed loads of WD40 into the locking area from the end of the door through the clip slot, worked the mechanism sprayed some more and finally it start working. My mechanic said these are very prone to moisture causing rusting on the moving parts.

Replace fuse 57 (15 amp) then disconnect battery and wait 30 to 45 minutes before reconnecting the battery.
My 2006 BMW 325I had the same problem with the door locks not responding. I checked all related fuses and found #57 (15 amp) was the only related fuse blown. I put in a new fuse and it still would not work. I then disconnected the battery for a while then once I reconnected the battery everything worked fine.
I believe I blew the fuse while repeatedly pushing the unlock button rapidly while walking across the parking lock to the car. I suggest only pushing the unlock button only once or twice.
