Hello dear friends ! I have lost one FOB of my h3 keys set..so i bought new FOB on ebay 315 mhz and now i need to tie it to my car. As i understand there are no way to do it without Tech2.

Step by step. And maybe i bought not right FOB ? HERE is photo of it:

Here's the setup from my Tech 2 with NAO 33.004

F0: Diagnostics
(8) 2008
LD Trk, MPV, Incomplete
Hummer
Hummer H3
5GT (ADM) Check your VIN
F1: Body
Uplevel Radio (Navigation Radio)
F0: Body Control Module
F5: Module Setup
F0: Programs Key Fobs
All fobs must be programmed in the same session. Ensure that the ignition is OFF.

To program fobs, press and hold the LOCK and UNLOCK buttons at the same time.
When all fobs are programmed, cycle the ignition to RUN then OFF to activate.
Programming may take up to 12 seconds.
Press [Enter] to continue.

Hope this helps!

The instructions say turn ignition off. But you must leave the ignition on but engine off. Then Tech2 screen you press enter to go into programming transmitter. Then you select the start button. Then you hold down on the lock and unlock buttons on a fob at the same time. The locks in the truck will cycle to tell you it programmed that fob. Then go to the next fob and hold down on the lock and unlock buttons until the truck locks cycle. You will also notice on the Tech2, the number of fobs programed will increase. You can program up to four fobs. When your done programming the last fob. Turn ignition off and then start the engine. Turn ignition off and press the stop button on the Tech2. Now verify all fobs work that were programmed. Hope this helps.
