2003 Hummer H2 Metal Key Replacement - Fast, Affordable & Professional
Got a call from someone over in Eden Gardens in Solana Beach. Guy had just bought a used 2003 H2 and the previous owner handed him one beat-up key. He wanted a spare before it gave out completely.
Simple job on paper. But when I looked at the key he handed me, the blade was so worn I almost couldn't read the cuts. The tip was rounded off and two of the cuts were nearly flat. That key had been turning a sticky cylinder for a long time.
I decoded it anyway with the Lishi tool right there in his driveway. Pulled the original bitting, cut him a fresh key to spec.
Then he put it in the ignition. Turned stiff. Real stiff. I asked when that started and he said the previous owner mentioned something about it "needing a firm hand." That's not a key problem. That's a cylinder that's been fighting worn cuts for probably years.
We talked through it. He decided to have me address the cylinder that day rather than let it go until he was stranded somewhere. Good call.
He drove off with a properly cut spare and an ignition that actually turned like it was supposed to. No dealer trip, no tow, no waiting a week for a parts order. Just done in his driveway.
