first off im new to this forum. if this forum is anything like others im member in then im in the right place.

my dads rig, a couple of weeks ago developed an issue. first it was the pass side door elec lock is stuck in the locked position. then the other day the drivers side door has done the same thing.

keyless hasnt worked for a realk long time, key will not unlock it either. can gain access thru the rear barn doors with the key. also, what ever ids going on has drained the battery.

have replaced battery hoping that would help, but no. any ideas? suggestions. thanks in advance people.
