Smartkey Starter now available for W203
It usually ranges from 100 feet to 200 feet for me. The signal is not strong enough to go through the thicker office walls. I can get my car started from the back of my home with no problems.
Viper created a module that you can attach to the SmartStarter for an extra $300. It will allow you to start your car from anywhere with an app that you can download to your iPhone, Droid, or BB... But, there is a $30 annual fee.

I really like it; it has become a convenience for me. I get up late for work and the last thing I want to do it wait for my car to warm up, especially during winter when I need to defrost the windows. I used to start the car up and leave the key inside, locking it with the valet... Unfortunately, my neighborhood has really gone under and people are really shady around here.
I also park my car out in the sun all day at work. All I have to do is step out front hit my panic button to start it up, go back and wrap things up and leave without having to air-out the car.
The must have is the keyless go option. I'd just like to get in, hit a button and drive off. Going to get that one soon.

The hot summers here in TX call for something like this...loved it in my Civic.
