Bought our T&C in 2018. No remote start. One fob didn’t work well unlocking any of the doors. Replaced the battery, same issue. Had to get up close and point the fob in different directions to the car to unlock any door. So I retired that fob as backup and started using second fob that came with the car. It has worked flawlessly until about a week ago it started acting like the first one. Installed a new battery, same issue. So do fobs eventually just start failing? Any recommendations? Thx for any help.
