I've just installed a security system with many options and am really pleased for the price. I bought a Marksman M7A because it was recognised by my insurance co. and they offered a discount to my premiums. Mind you, it took me about 8 hours to install after probably about 4 hours of studying and planning with my 02 schematic, However, it has every conceivable option with it, immobilizer, remote start, door locks etc. including a turbo cool down timer. It's simple so it dosen't work of temperature but it allows for either a 1, 3 or 5 min cool down after key is withdrawn and automatically locks the doors while doing so. Immobilizer option involves wiring a $3 ISO relay to detect bad guys while armed or remotely started, to disable the starter circuit. Less than 200 bucks Canadian. Oo.
