If you are looking to buy a keyless remote, you minds well buy a legit alarm and if you want remote start. Those Key fobs are not cheap at all. I ended up putting a Viper car alarm with remote start and love it. It will page my remote up to a mile (yeah right) away and let me know what is going on. But the remote start is nice and is does have some great range.

here it is, and no I didnt pay that price.
