My car is a 98 Accord EX I4. The car came with a factory alarm but the previous owner added an aftermarket alarm as well so the car has both. The Honda remote will work on the car but won't disarm the aftermarket alarm. The remote says 'Prestige' on it. My question is can i go to autozone or strauss and buy a remote to program a 2nd remote or MUST it be a prestige remote?
