PM Auggie Mathis, he has all the keys.

Hi Phill,
I mailed the key back today. Please let me know once you recieve it. Thanks a lot for helping me out with the key.

Hello guys,

I also need a roof rack cap key for 03 H2. My lock is #003
I need also one complete cap because one is missing - best also #003, or any another cap with key will be helpful.

Could someone help me?
I'm from Slovakia (central europe)

Regards,

Duro

E004 Key
 

Don't know if I can't PM because I am new but I need an E004 key, if someone could help I would appreciate it, I'm in Savannah GA

need E001 roof rack key please
 

If some one would send a copy I would gladly pay for postage and key. Just don't want to go through lock smith and pay the the extra.

How do you find what key number you need?

If you look at the lock there is a number on the round plate where the key goes in. It sounds like they used E001 up to E005

You can purchase the Hummer H2 roof rack keys pre cut at any GM dealer parts dept. Just give them the four dig code on the lock cylinder, make sure to check all the cylinder codes as sometimes they are different. Its the best way and its the factory GM key so you know it will work the first time.

I have an 08 H2, but the round plate doesn't have any serial number. Do I need to take it to a lock shop?
