When I use my key fob to lock the doors it sets off my alarm. 1999 VW Passat.

If I use the button on the key fob to lock my 1999 VW Passat it sets off the alarm. I have to walk around car, open passenger side door and press button to lock all doors. Whats wrong with my key fob?

My older Subaru started doing something similar and I finally had a friend figure out how to disable the alarm (but my fobs still work).

I think the shock sensors or door locks or something must get a bit flaky with age, or perhaps it's a simple grounding problem. Sometimes the solder joints crack with age. Tracking down the problem could be a pain, and the dealer will want a diagnostic fee just to mess around with it.

Do you have another fob you can try to rule that out? Maybe the fob got squished and the contacts are making the wrong connection when you click it.
