well, i have some shitty alarm/keyless entry that came with the car. it worked for a while but now the arm/lock feature doesn't work anymore. the little button on the remote red lights up, so i know the button is functioning. but it doesn't lock. the unlock works fine though. i changed the battery but that didn't fix it. i disconnected my car battery in an attempt to reset it. that didn't work either. do you guys have any suggestions?
