Here's a website that has a few ignition interupt systems for sale.
I was thinking of buying one of the top three, but don't know which one.

And once I buy one, where can I have these installed? Is any stereo/alarm store okay? I'm new at this, please be patient.

 

The keypad one is effective and reliable, but is ugly looking mounted on the dash..

The "touch and go" is an easy one to figure out.. theres only so many dash switches to wire it up to and would take about 20 seconds to test every available switch..

Keysense is a good system, but not as reliable as the keypad due to the fact it needs components within the ignition tumbler to operate .. I would believe a worn out key could actually throw this system off..

of course, none of the above systems are fool proof..

 

I kinda know this mechanic who said I should get this switch that goes between the wires that controls the ignition. Basically, with the switch turned off, there will be no spark, thus those b**tch A** ***** can't take your ride. And he said I could hide the switch almost everywhere inside.
Sound good, or should I just get a backup battery for my alarm WITH the fuel cut off or ignition cut off?
