morning guy's,they started the spark plug thing about 10-15yrs ago in South Africa and we put in a safty film, the new thing is a normal gate or alarm remote at a shopping centre hold the button in while somebody is locking a car,how many people look when they push the button,the remote blocks the signal and the car is left open for them to steal everything bought at the last shop,works with 90%+ cars.
