My 90 Accord came with the factory alarm, including keyless entry. The keyless entry has stopped working, but all other security features work. I know its an old car, but thieves value the parts. The power door locks work, is it more likely the wiring of the power door lock control unit to the security control unit is bad or the security control is bad itself. All other features of the security control unit work, I tested them.

Any comments?
