Just got my H3 last week and also don't have the roof rack key. It's an SP5 just ike noted above. Have been doing a lot of reading and just joined the forum to post here. Izanchor, I'm also in Canada (Calgary to be specific). Can you make a copy and mail one out to me?

 

I'm in Minnesota, and I need a SP5 key to. All the original owners of these H3's did not respect the roof rack keys.

 

You can get them fast and cheap now on eBay... Seller is ' Filecabinetkey '. I ordered a couple for a set of racks, figured I'd give them a try vs the pita and kinda costly locksmith route and they were perfect. Had them super fast for like $6 per.
Good luck

Where the hell do I find the key code for a 07 h3 luggage rack?

 

 

LMAO Thanks

 

It will only be there if the roof racks are O.E.M. not aftermarket. The way you can tell O.E.M.'s is the word HUMMER is molded into the end caps. If the end caps are 'smooth' they're aftermarkets. Infringement rights came into play with the aftermarkets so they offered stainless steel stick on letters for the word HUMMER.
EDIT: OMG!!!! I just noticed this is an 8 year old thread!.....sorry Doc.

 

Your key code is typically stamped on the face of the lock.
