My toddler was playing with the key fob transmitter for my '99 3.5 RL. He did not get it wet or slam it to the ground, just pushed the buttons a zillion times. When I walked out to the car later, the Lock, Unlock, and Trunk buttons did not work. I tried taking the battery out and putting it back in as an attempt to "reset" the transmitter, but it did nothing and the red LED stays on constantly since I did that.

I've been snooping around the internet looking at replacement key fobs, but I'm not convinced that's the problem. I think the one I have will still work if I can just reset it to the original settings somehow. Any tips or advice? I really, really, really do not want to take this to the dealer to be fixed, in fact I'd rather just manually lock/unlock the car for the rest of its life.
