hi guys
just to share my experience - what tcm carries is actually a simple alarm and i had it installed sometime in Dec09. Cost about low-end of S$100, so i reckon it shoudn't be too far off now.
According to SE, the alarm is hooked up to the car horn. So, the car horn will go off if it detects a break-in and stuff. I didn't have to change another I-key and I wasn't given another I-key, but it rendered my spare key useless. So if you have the car alarm installed and use the sparekey to physically slot into keyhole, the whole alarm system will be activated.
It comes with what most people call "auto-lock" - so basically, you start engine and then you step on the brake pedal to activate the auto-lock. It's good to prevent some cheeky bas**** from opening your boot from outside whilst you're in your car.
SE also said that most of the stock cars that drove out of the TCM showroom are only equipped with an immobiliser and not an alarm system. Well, this statement would vary because different bros probably got different bargains from their sales engineers at point of sale so maybe yours came with it.
small price to pay for ease of mind in my opinion!
