Unable to open, lock, horn or open the truck after replacing the battery. i did press down both open & close button for 7 seconds close to my car but still no go. can you help

 

have you tried opening the remote, and looking at the connections? Sometimes the solder will come loose on the connectors that hold the battery in place. I've fixed a few temporarily by just pushing the connectors back in the board.

 

i did clean all the connectors. had to go to the dealership with both remotes and they had to program the remote. said it happens when you sometimes replace the battery. atlest it is working

 

For future reference, this website is handy for programming remotes.
