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?

did you check the battery in the keyless remote?

battery in the remote would be my guess also

Those units dont just blow out check all your fuses .

remote batterys only have a 6 month to 2 years life says the manufac of the batterys even if the lil light works it does not mean it has enough power to transmitt
