Is your alarm the 2 button or the 4 button remote?

Mineis the 4 button with all the options, I don't recall how the guys mounted mine, but the range is really good. The only problems I've had with it are

1. There are alot of other cars that might be jamming the frequency ie range of your remote.
2. Sometimes for extra range I touch the remote to my chin and it extends my range by half.
3.Also if you drop your remote a handful of times, the battery terminals can become loose therefore giving you the perception of a shortened range as well as make you think you have a drained batttery. In that case, just open the case and manually tighten the metal prongs so they are in complete contact with the battery ends. This has helped me out a bunch of times.
