07 Passat Key fob quit working
 

07 VW Passat key fob quit working. I have changed the battery and still won’t work. I can’t lock the drivers door when I push the lock button. The three other doors lock when I push the lock button on the drivers door. To get the drivers door to lock I have to lock it from the passenger front side button. I have only one key fob for this car when I bought it.
