In about 2 seconds
I had a 94 Tempo. It didn't have a chip in the key, but nobody would have wanted to steal it, at least not near the end of the time I had it.
An older car, pretty easy. A newer car with a chip in the key, next to impossible, they get towed away.
Even faster than that. Less than 1/2 min.
if they want it, they will get it in a very short time. a chipped key can slow them down but it is not foll proof.
It depend on how big a brick or hammer you have.
I think I just saw a car get stolen a car pulled up a man got out keeled down at the door for just a minute got inside for a minute turned it on took off an the car he got out of followed it just looked suspicious to me I was wondering how fast can a car be broken into an started?
