Door Lock problem

[BillysBowties]

My remote control only unlocks the drivers door now, I have to open the lift and tail gate by the key and the rest of the doors in side the truck can anybody help on that, and also the gas gauge always reads 1/4 or less all the time. Could it be a relay or fuse I don't know. 2001 2 wheel drive. Thanks alot.
