Need help with Keyless entry!!!

Hey guys, I recently bought a 4 door black, 06 Grand Prix... My gf and I were walking out of walmart the other day and she had my keys and repeatedly hit the unlock button on the car while i tried to take keys from her(we were goofing around). Now my remote will not do anything, no unlock, lock, trunk pop, no nothing. I replaced the battery but no luck. Anyone have any ideas? Thanks!!!

you could try to have it reprogrammed into the system. its possible that there was a fail safe if there is a repeated signal sent that it locks out the code. don't know if thats true but it is possible.

the easiest way to program it back in the system is at a dealership, but i think if you look around you can find an easy way to do it
