I put new batteries in the key Fob And the doors locked and unlocked perfectly. But when you press the trunk button nothing would happen. So I took the emergency key out and open the truck with the emergency key. The hazard started flashing for about five or 10 minutes and now I’m locked out of the car. The car will not respond to the key Fob. Luckily the batteries in the trunk so I have unhooked it let it sit and hooked it back up again ...same problem I now have an open trunk but a locked car I can’t get into. I would much rather not be able to get in the trunk of course but be able to get in the damn car. Should I close the trunk and try to unlock The car again? Thanks

Did you try locking then unlocking the car? The alarm module tends to fail on these cars. The easy solution is to simply remove it from the car .
On US cars it's on the driver's side so mirror image everything you see here.

Should fix the lock problem.
