I am selling an Excalibur remote start with bypass module. I had installed in my daughters Trailblazer about a month ago. I just sold her Trailblazer and the new owners did not want the remote start feature. This does use the OEM key fobs. Just hit lock button three times and it starts right up. I do still have the box, paperwork and all instructions as well as the Trailblazer wiring diagram for easier installation. I also have all the wiring harness' for the remote start and bypass module. My current Trailblazer already has a remote start, so I just dont need this one. I am asking $60 shipped
