What's your car bro? Is it an oem remote alarm/central lock system?

Had a problem with my corolla gli before with similar symptom as yours - using the remote the car respond with sound and flasher blink but won't lock/unlock even though the central locking is working when pressed from the driver side lock/unlock switch.

I did some tinkering on the alarm controller box and found one defective I.C. which was part of the circuit that triggers the lock/unlock switch. Circuit ok after replacing that part.
