Anti Theft System Help

[salenks]

Hello,

I would like to know if there is a way to add a switch to block the starting of the vehicle or any other kind of additional protection from theft. I am planning to have this lock installed http://www.zeder.rs/zeder.php?lng=en but I heard that even that is possible to be bypassed.

I have a friend who added a switch that needed to be presses before you could start the car. It is somehow connected to the clutch. I have an automatic, so this kind of protection will not work for me. I do have an option to enter a code that is required to be entered before you can start the car but anything that is from the manufacturer is easily bypassed.

I am in an eastern European country where they steal these kind of cars a lot.

Thanks for your help,
