Since the alarm responds to locking and unlocking the vehicle and you have tried more then one remote this sounds like the control unit/ecu (brain) itself is at fault.The antennae signal looks to be working as well since it recieves the signal to lock and unlock the vehicle.This sounds like the control unit itself needs either removed and repaired by an authorized repair center or removed and replaced to correct this fault here.You would need to speak with an alarm/audio install facility to see if it can be repaired or if it needs replaced.
