We just bought a 1997 Protege and realized that the car alarm will go off if the key is used to open the door. The keyless entry box must be used to unlock the doors. I want to be able to open my car manually even if it means not having a car alarm.

The alarm was not factory for this model, but the keyless entry boxes say Mazda, so I'm guessing someone went to a dealership and had it added after buying the car.
