How to bypass the security system because I had to pop the lock due to. It being abke to afford a new lock ignition switch

I am 46 now and have been installing car stereo since I was 15 years old this is a very common problem when installing remote starters on a car that already has a stock security system we don't waste our time hacking into automotive wiring systems that much in trying to reinvent the wheel we usually just fix it by using a bypass unit after all I don't work for the dealership I work for a car stereo shop unfortunately might cost you anywhere between 20 bucks and 80 depending on vehicle I'm not sure what is inside of bypass units if it is some sort of relay or relay switch or wherever but try contacting your local car stereo professional if anybody knows anything about car alarms going off when they don't want them to it is them
