Had some weird glitches a while back - tach was jumping intermittently and finally went dead, alternator was not charging, but now is working. One of the problems that started at this time is the functionality of the remote FOBs. They no longer work to lock and unlock the doors when the car is running. I used to be able to get out and lock/unlock the car with one remote while the car is running with the other key and remote in the car. Batteries have been replaced. Both FOBs act the same. Have searched the forum, can't anything applicable. 2001 T&C Limited. Thanks for any help!
