Do you know someone with a Trailblazer w/keyfob you could program to yours to see if its capable?
A few minutes to program yours and reprogram the donor vehicle back is not difficult.
Do not need dealer to perform the program!
Also no dealer needed for keyfob as well!
I got a spare designated 3rd driver after i programmed it from an E-bay vendor for under $10 and works perfect...
