How can I deactivate alarm with no key fob or original radio?


New Member
When I bought my Civic it came with no key fob or radio at all and the security module on the drivers footwell was unplugged, if I tried to plug it back in the alarm would instantly go off. I’ve tried deactivating it by locking and unlocking the doors but no luck. My grandma has a civic from the same year and she is willing to gift me her duplicate key fob, but even if I programmed it to my car with the alarm going off I don’t know if I would be able to deactivate it without having the actual radio. Does anyone know a workaround of some sort or would I have to buy a new security module or Honda radio?
