Hi

You have to replace the latch of your trunk. The contact is in the latch and most of the time you have to change the wire and the connector because they are oxided and make a resistance.

If I remember well you cannot remove any fuse to solve your problem because the fuse will affect some interior lamps and door lock system.

I had the same problem on a VW Golf

First to turn off the alarm you simply put the key into the drivers door and turn it to unlock the door twice, this is the factory setting to turn off activated Volkswagen alarm. As for the power locks they are air activated, in the trunk near the latch there should be a small electric motor that drives a small air pump with air lines running to all your locks. If this electric motor as worn out your locks will not operate, simple fix replace the motor. I'd try a used one first from a scrap yard to make sure but always check to see if there is power to the motor (you will need another person with a test light to perform this job). Let me know if this works. Vdubs 4-ever !

I found a thread - http://forums.vwvortex.com/zerothread?id=1542461 that details the repair of the soldering on the key lock door module. Our 2000 new beetle had the same issue. Also sometimes it refused to start. Soldering pins fixed it all.

Also see http://forums.vwvortex.com/zerothread?id=1015107 for releasing window from track, And door handle from inner panel.

I ripped the door apart and re-solderd the pins. I only had one pin with cracked solder but two others looked thin so I did them while I was in there. It's about a four or five hour project if you have all the tools. (8mm triple square also called an 8mm internal was the hardest to find - Also needed Torx T8 T10 T15 and T30 plus Philips Screw Driver. )
Project is difficult but not too bad for the mechanically inclined. A 7 on a scale of 10.
Since re-soldering pins - no more issues! My guess is that a VW dealer would get $200 for a new moduel plus 5 hours of service time for this gig - easily a $500 to $1000 bill. My cost - several new tools - about $25.00.
