Looking at a wiring diagram for the Mitsubishi factory alarm it ties into the headlights, trunk lock door lock, hood switch ,ignition switch, starter circuit and lots more. If the factory alarm fails I would have expected it to have presumed the car was being stolen and it would have tried to protect its self by sounding a horn (separate to the normal horn circuit), it should flash the lights and most importantly it should prevent ignition preventing the engine from running. Make sure your car absolutely does not have an aftermarket alarm if it does that will be easy to remove. If its a factory alarm unfortunately it would be easier to fix the alarm than try to remove it or trick. Its complex you need a wiring diagram for sure, someone with electrical or alarm experience will have to look at it.

There is no disarm switch shown on the Mitsubishi wiring diagram.

Factory remotes will usually have some kind of brand name on there or company logo. If the remote has a logo or brand other than Mitsubishi, that's a good sign it is an aftermarket alarm.

I contacted the seller and he said there was probably a switch or key lock in the trunk that I could turn. do you know anything about that

I'm not sure how to fix it, but I have figured out how to circumvent it (I have the exact same issue). When you turn your key to the right to unlock, hold it in that position while opening the door. That'll keep the alarm from coming on. If you forget, just turn the key to the right while the dor is open to stop the alarm.
