Preventing car theft

I have the cheapest way without spending a dime " i am not going to say on here which one " for our own good , i have a customer which owns a fairly new kitty cat that parks in the parking garage in airports a lot , and i showed him a certain relay to pull and the car will not go any where, and it's free. throw it in your pocket or put it some where in the car . not saying it can not be towed but so can all the other anti theft devices can too.

 

Well it happened last night. Went to start the car remotely and nada. Went out and drivers window broke out.
Opened the door and alarm went off, must have crawled in and out. Wires under the glove box were pulled down.
Had the town car blocking the scat in. Can't have anything nice.

 

Curious where the nearest stronghold of Democrat Voters is relative to you.

 

I would GUESS That a good kill switch to install would be one that interrupted power to the spark box so that no matter what chicanery the thugs used to try to get the car started, they would not be able to convince it to SPARK.
