Hello and welcome to JustAnswer!
What kind of problems are you having?
If the keys stopped working independently of each other then the problem is with the keys themselves.
What normally happens on these is the piece that holds the battery to the circuit board inside the key will break free of the circuit board. These terminals are soldered to the circuit board in three spots, and these joints are all needed for the key to work. Over time they will break free and the key stops working.
Open the keys up and check for breakage of the solder joints. If you find any breakage or cracking then you can remove the batteries and carefully resolder the joints back together and the key should work again.
the breakage was recognized, when the first key stopped months ago, and i resolder still doesnt work does it need to be reprogrammed?
What is it not doing? If you leave the driver's window down, lock the door with the key fob, watch the security light until it's at a steady slow flash, and then open the door from the inside does the horn honk and light flash?
If not, do the interior lights come on when you open the driver's door?
