When you open you back gate you should have a round knotch on the right side and the extention that fits the jack also fits the spare tire release. Counterclockwise, and that should work. No special or spare key needed just your tools provided.
Check the owner's manual - if it is like my Bravada there is a safety catch that has to be released prior to the spare tire dropping
The same crank used for the jack also cranks down the spare tire. The jack and crank are located under the rear seat(s). If the lift system has not been serviced it may be necessary to pull the spare tire down as somebody operates the crank to release it. www.trailvoy.com - All the answers for your Trailblazer from true enthusiasts!

Read the owners manual. There should be a key/tool provided to operate the spare tire holding mechanism.
