RE: Equinox keyless remote start short range
GM's remote start system is great, but has a couple flaws. the run time that is not adjustable, and the range of the remote. Because the system uses the keyless entry module, it is limited in range. There are aftemarket modules that use an external antenna and replacement remote that activates the factory remote start.
If you have a question, ask it in the forums. I will no longer be answering questions sent to my email.
