It will take 10 secs and please dont ask me how to start a mustang without keys. lol
Also, you are suppost to have a few spare keys
its only 4 wires you need to connect.........
I saw a thing on 60 mins or some news show once where they showed a person with a key on one side an another with a coat hanger on the other and the guy with the hanger beat the key into the car 4 out of 5 times.
so like I said a person that knows the 4 wires and has a coat hanger could take your car quicker then you could imagine. If you do not have an alarm in your car I feel no sorrow for you when it is stolen or broken into. The times we live in almost dictate its need even if you are in a small town with low crime. A descent alarm will run ya 2-300 bucks and will scare off 90% of the theives out there.
At the very least you can add a flashing led and a simple but effective starter kill. When I am feelin extra paranoid in a bad area I just engage my starter kill by removing the cig lighter and then it will not even crank. I guess if the thief had an extra cig lighter plug he could take it then but I don't imagine them checking that if it doesn't start.
