How do i get the factory security to shut off ive tryed using the key in the door and that dont work no more and i pulled fuses and relays it start and shuts off and the security light is blinking

pull the horn relay till its sorted
factory alarm may need a diagnostic scanner
might be a faulty module

Put the battery cables back on shut the doors and lock the drivers door with the key then unlock it with the key. This will shut the alarm off it it goes off and may get the car out of the lockdown mode it seems that it is currently in. If that does not work you may try and call your local Mitsubishi dealer and ask one of the guys in the service or parts dept if the car has a lock down mode and what procedure has to be done to unlock it, mor than likley the will tell you and you wont have to spend a dime. This is all regarding the factory alarm however.

If it's the factory security system that honks the horn and flashes the headlights, you can shut it off by turning the key in the door cylinders or in the rear tailgate key cylinder. If it's an aftermarket alarm, look for a small silver switch under the dash and usually turning the ignition on and flipping that switch will permanently put the alarm into valet mode. Good luck.

Just guessing but is there a security system in htis car?
Being a 95 it may have a factory security, the key does it have a chip built in?
You can bypass and use a regular key,
if none of these apply check idle air,

Try "cycling the key in the passenger door lock. Turn it all the way to the right and all the way to the left.
