You can program the remote portion of your 2008 and 2009 Hummer H22 remote yourself at home with these simple instructions.
There is also a free programming tutorial video below to show you how easy it is done.
Switch ignition ON.
Repeatedly press vehicle information button Fig. 2 [A] until PRESS TO RELEARN REMOTE KEY is displayed.
Press set/reset button Fig. 2 [B] until REMOTE KEY LEARNING ACTIVE is displayed.
Programming mode activated, proceed as follows:
Press and hold LOCK and UNLOCK buttons on first remote transmitter simultaneously for 15 seconds.
Wait for acoustic signal (indicates correct programming).
Repeat above procedure to program remaining remote transmitters.
Switch ignition OFF to exit programming mode.
Remote transmitters can also be programmed using diagnostic equipment.
NOTE: A maximum of 8 remote transmitters can be programmed.
I am considering purchasing 2 new 4 button remotes for my 2009 H2 hummer and doing the programming myself rather than going to the dealer to provide the key fob and the service. However I could only find DIY instructions for the lock/unlock buttons of the remote, not the “remote start” feature. Is the remote start feature something I can program at home as well, or is it dealer-specific?
Thanks
Unfortunately, most of the Hummer remotes must be professionally programmed by a GM dealer or a locksmith.
