I had the same problem. Couldn't lock or unlock using fingerprint on any door other than driver's side. Turns out that my battery needed replaced. Completely fixed it. Was told that these systems are affected by a low battery. I wasn't driving the vehicle enough to keep it charged enough.
Likewise, fingerprints do not work on any of the other 3 doors! Interesting….I would have never thought that the battery would affect the intelligent access! Thank you so much for your quick response! Off to get a new battery! I appreciate your time and I’ll keep you posted!!
Some other tell tale signs of weak 12 volt battery are: as you approach vehicle welcome lights are not activating and probably your start/stop feature no longer stops the car once it comes to a stand still. The disabling of the start/stop when 12 volt battery gets weak had to be reprogrammed since the car might not start up again in traffic.
Wow! Ok definitely don’t want that happening! Yes, it sounds like the battery is ready to be changed!! The welcome lights on the ground and as I approach the car are not working either. Thank you all for your wonderful and insightful information! Very much appreciated! Have a great day everyone!!
