Hello guys!
My remote transmitter fob suddenly stop working long time ago. I have just one fob from previous owner when I purchased my H2 and since that time transmitter fob was working good, but one day it suddenly fail to work. I changed fob battery, but it doesn't help. My mechanic friend try to find out what is wrong and tried to fix contacts inside fob with small soldering iron, but it didn't help either.
Any suggestions or advices, please, what to do with this one?

 

From another forum but worked for me when I bought a new FOB for my 2007 H2:
Put the key in the ignition and don't turn the car on. While holding the unlock button down on the driver door, turn the key on and off twice (without turning the car on, turn it to the on position and then to the off position). You should hear the horn honk really quick and the door locks will cycle, this means the car is in program mode. Take the key fob and hold down the lock AND unlock buttons. After between 6-20 seconds, the locks will cycle, that means it's accepted the programming. Repeat with for additional key fobs. When finished with fobs, turn the key on and off, you'll hear another honk, which means it's out of program mode.

If this doesnt work, you might need to buy a new fob

Thank You very much, guys, for Your help! I found this way of fob- programming for 2003 Tahoe(Suburban, Yukon, Silverado, Escalade and Hummer H2) on You tube! I ordered already two new key fob transmitters from: Replacement Car Remote Key Fobs & Transponder Keys. When I will receive them, so will try to program them.
