Just bought a 2006 H# and it only came with a key. No FOB remote at all. Does anyone know if I can buy a generic one and get it programmed, or do I have to go to GMC and get one there? Thanks for any info!!

 

Ebay has GM fobs for H3s all the time, and then get it programmed at a GM dealer. Many full service lock shops can set you up as well.

 

Like Doc said, there is a bunch of them listed on Ebay. Search Ebay for a H3 Key Fob, make sure that it includes the board inside, some are just the covers. Dealers and Locksmiths can program the Fob to you vehicle for a fee.
