2009 Hummer H3 Transponder Key Replacement - Fast, Affordable & Professional
I got a call from someone over on The Avenue in Ventura. Her H3 had been broken into the night before, and the spare key she kept in the center console was gone with everything else. The truck itself was still there, but knowing someone had a working key to it was enough to keep her from sleeping.
She wanted the locks re-keyed. I had to explain that re-keying the door locks does not help when the real threat is the transponder. Whoever took that key could still walk up, put it in the ignition, and drive away. The door lock situation is almost secondary.
So we did the full reset. OBD port, diagnostic equipment connected, all keys cleared from the immobilizer memory. Then I cut and programmed two new keys on site and confirmed both started the truck before I packed up. The stolen key is now just a piece of metal with a chip that the car ignores completely.
She asked if the dealer could have done the same thing. They could, but she would have waited days for a service appointment and paid significantly more. We handled it in her driveway in about an hour.

“Locked out on a weekend night and everyone else wanted $300+. EZ Car Keyz sent Roman late at night for much less. He worked for over an hour and did not give up until the door opened. They even made a new key on the spot.”
“I had two Subaru key fobs made and Marco provided excellent service. He stayed persistent through multiple part orders to make sure everything was correct. Very thorough, punctual, and great communication throughout.”
“Tim went above and beyond. I struggled all day trying to program a new FOB and nothing worked. Tim helped me patiently, even recommending cheaper options since I was on a tight budget. He eventually came all the way to Ojai late at night and fixed everything.”
