What to know about Hummer keys.
Hummer's H2 and H3 models were built on GM platforms and use GM-style Passlock security, with the H3 offering proximity key options in later model years.
Hummer key blanks and fobs can require more searching to source since the brand was discontinued in 2010.
Whichever Hummer you drive, our technicians carry the key blanks and programming equipment to handle lockouts, replacements, and broken-key extraction on-site, with no tow to a dealership in most cases.

Do you come to where my Hummer is parked?
Yes. We are fully mobile. Wherever your car is in our six-county coverage area, a technician comes to you.
Is a Hummer key cheaper from you than from the dealer?
Usually, and faster: there is no appointment wait and no tow. Call with the year and model and we will quote it on the phone.
