I have a 2015 volkswagen passat tsi, the fob for locking / unlocking the car has stopped working. The led on the fob still illuminates. I tried replacing the coil cell battery (cr2032) on the fob, but the issue persists.
I only have the one remote, but I do have a frequency analyzer. the remote typically broadcasts at 314-315 MHz, which it still does, before, and after changing the battery.
in accordance to instructions found here:
I tried resetting the key fob, by locking the car. Press and hold the lock or unlock button for one second. Using the master key, unlock and relock your Volkswagen. Your key fob should reset itself.
Perhaps it is a fuse? or something else?
Any insight would be appreciated. I'm also wondering if there is a fuse associated with this device.
