BE CAREFUL HERE!!! I negotiated an alarm system install and after thinking about it for a little bit, I decided I wanted another system that would use my existing key fob. I had already paid $600+ for the system and the manager was looking for a system that would use the fobs for the truck. He came up with a system that was only $349 but it wasn't on the floor to see a display with a price. While he was on his computer, I used my phone to scan the bar code and the system he was selling me for $349 was only $189. I got a refund on my original purchase and left after telling him I thought he was trying to screw me. He told me the $189 system was only a remote start and he was "throwing in" a security system with it. Watch these guys and make sure you're well versed on what they are selling you. I'm going to use someone else for my installation.
