First you get the code to see what is causing this. If their was a easy way to disconnect the security then it wouldnt be secure. But if you had a wiring diagrm what you would need to do is put a resister inline. All cars are different to deter thieves from doing this. One car my take 5ohm resister while another may be 15 or 20
How do you disable the security system on a 1999 Mitsubishi Montero sport I have tried unlocking the door with the key numerous times dis connecting the battery etc.
