Key Fob doesn't lock doors but sets alarm
 

2003 Jetta

When I use the key fob to lock my doors, the doors do not lock but the alarm is Electronic door lock buttons do not work either... so the only way to lock the doors is to manually push down the lock.

What can I do to troubleshoot this problem or is there a simple solution I can do?

Thanks for any and all help you can offer!
