Hey guys, i was wonder how good these Transponder Security Systems work. I have one in my new Integra, how good are these things from keeping the car from being started with out the key, and can an aftermarket alarm be added easily with these things?

 

to a simple theif the factory will help, but to a pro it's nothing, you should add layers of protection. like adding an alarm with your factorytrans. also a hidden kill switch so in case they find your alarm and then maybe a tracker such as gps or lojack from towtrucks. no matter how much you spend or add always gota watch ur car.
