Kids were playing in the truck yesterday and left the lights on, this morning the battery was dead, its a 2005 GMC canyon crew cab, the 2 rear doors and the front passanger door DO NOT have key holes, only the front driver side door, so i go to put in the key to unlock the door, (to jump start the truck) and it does nothing, will not open the door?? Call Roadside service, they show up and eventually get a wire thingie in there and flip the door lock button, the door opens, jump start the truck, all is well, then we look at the only option to open the truck with a key, the driver door, and the lock when used with the key, will only LOCK the door, it will not open the door, i never used the key to get in the truck, have always used the keyless entry (remote control) to lock/unlock the truck. It seems like there is something wrong here, it cannot be that there is no option to unlock the door, lol, i tried spraying wd-40 in there and to work the key around, still nothing, the key slot is vertical and will only turn to the right, to lock it, and does not go all the way horizontal, only about half way between vertical and horizontal, and it locks it just fine, everything else works great and like it should, what do i do about this? if the truck battery dies again i dont want to be stranded, anyone know anything about this? cant really afford to take the truck to the GMC dealer at this time. thanks.
