Daughter had same problem on '05 T&C. Neighborhood mechanic searched Internet and found 80-90 others with same problem right around 40,000 miles. Free solution was to pull yellow 20A IOD fuse in right front corner of fuse box under hood, wait 10 seconds, then reinsert fuse. Should solve problem as long as you don't lock doors with FOB. You can unlock doors with FOB, but apparently locking with FOB causes the problem.
Permanent solution is to have dealer reprogram computer for around $50 which is what my daughter chose to do because of inconvenience of not being able to lock doors with FOB when getting baby/carseat out of vehicle.

Look for fuse or relay problem. A bad (shorted) door lock switch can also cause trouble. Need to dig in and start looking at each component one at a time.
good luck

There is an ecu flash for this repair. You may get the locks to start working again with a battery disconnect.
