When I got into my car this morning i saw a strange looking Microchip on the floor by my seat. It is about an inch wide and says "the Silencer" on it, and it has a little push button with a light bulb icon on it as well (that does nothing when you push it. i thought nothing of it until i tried to start my car and it wouldnt even click. i then put 1+1 together and figured out that it should be plugged in under the drivers dash for the car to start and is very easily removed. is this a stock anti-theft device? (part of PATS?) if so what happens if i lose that little bastard?
