Is there any way to program both buttons on the keypad chain so that one locks and the other unlocks on a 99 Corolla. I'm always second guessing if I locked or unlocked it. This is kind of a stupid idea they had why not just make it like every other keyless entry pad with panic/lock/unlock button. I just found out the other day in the manual that you hold the one locking button down for a while to activate the panic feature.
