2004 town and country van is not receiving signal form key fob to lock or unlock doors.Had a key fob programed at locksmith that worked for a month then quit working.Took it back he checked and said it was transmitting and van was not receiving the signal.Doors lock and unlock with switch inside.They lock at 15 mph as it should. What to do now.Help please

 

- pull the NEG battery terminal off for 15 minutes
- then put it back - what happens - does the auto unlock ALL work now ?

 

Thanks but I have tried that and didn't work.
