I'ad installed steel-mate security system with remote start option almost 6 months back and yes it costs me for 10k.Till now its working perfect ALHUMDULILLAH.I must say its very cool and problem-free system.Because of following Features in it.
1) The remote is rechargeable.It comes with car charger which takes only 5 minutes to full charge.Standby time 32 days(checked myself)
2)Its range is 1km which is awesome.
3)The remote has screen which shows the current status of your car.Means if you start your car with remote and suppose you forget after starting your car.It will remind you by vibrating and beep showing your car is start.(after every 30sec)
4)Shows you cabin temp of your car and time.
5)Incase someone touches or try to open your car and you are standing within the range of 1km.The remote will start vibrate and shows hammer on the screen which means someone damaged or tried to open your car.
5)With this system one can also switch off the car with remote even if its started with the key.
I think these features in 10k isn't a bad deal :).
The one and only drawback in this system according to my point of view is,The spare remote doesnot work if other remote is switched on.Its remotes can be switched off like cellphone.So if you want 1 remote to work then you have to switch off the spare one.
