VW Cabrio alarm problem & key won't lock door
 

2002 VW Cabrio alarm problem: alarm will not un-set. Door will not lock using the key OR the remote. Hitting "alarm off" button on remote, it unsets, then arms again immediately. With engine running, alarm will set itself to on (beeping to let you know it's armed), then start sounding if you don't hit the "alarm off" button within one minute. Brand new batteries in remote, both remotes having same problem so it's a problem with the alarm itself, NOT the remotes. Remote door lock and unlock stopped working 5 years ago. Any suggestions?

I recently had a problem with my daughters Cabrio, it turned out to be the door handle. Inside the door handle there is a little piece that turns the locking mechanism and it had broke. This will prevent the alarm to reset. I had to buy a new handle which was $22.00. There is one screw to remove the handle and only takes 20 minutes to replace. I hope this helps you.
