I have a 2006 Trailblazer it has the keyless entry system all fuses are good to go. I've followed the remote entry programing steps. The locks cycle but then nothing. I have been looking into the issues with the loft gate module issues but the rear wiper, defogger and all inside lock and unlock buttons work. I can still use the key to unlock the driver side door and the loft gate. Locks engage and disengage as they should. I bought the vehicle second hand, one previous owner and he stated the fob battery had dies and he never replaced it. I replaced that battery as well as purchased two new remotes. Any ideas?
