So I read on one of the tc forums that someguy is doing this. I have a hornet 740. Any idea/ Thank you!

Not sure about that exact one, but I know on mine, if I use the key remote, it will set off my alarm. It doesn't recognize where the car is being unlocked from because it wasn't the alarm remote. I took out the battery in my key to prevent that.

depends on the alarm being installed.
