I bought two keyless/fob remote for my 2007 Chevy HRR - LS, and after numerous attempts assisted by Utube videos; I was unsuccessful in programming the remotes. I need some help with accomplishing this task and avoiding high dealer fees.
Does my car have Remote'Start readiness; how about 5th Door Keyless Entry?

 

Welcome. Your remotes will have to be programmed at a GM dealership with a tech 2 scanner or a locksmith/repair shop with a device with those capabilities. Can't be done at home; those videos are actually for vehicles prior to the system used on the HHR. As far as your other questions; those will be addressed in your other thread.
