🔧 PRO TIP
The 2010 H3 runs GM's PK3+ (Passkey 3+) immobilizer system with a Megamos ID 13 transponder chip embedded in the key head. The key blank is Strattec 5911588, and the remote portion uses the OUC60270 or OUC60221 three-button fob at 315 MHz. If you lose all keys, the theft deterrent module on these needs a 10-minute relearn cycle per key through the OBD-II port. No shortcut around that timer.

2010 Hummer H3 Transponder Key Replacement - Fast, Affordable & Professional

Got a call from a guy near the Oxnard Skate Park in Oxnard. His 2010 H3 had one key left, and the blade was so worn it barely grabbed the wafers anymore. He had to jiggle it three or four times just to get the ignition to turn over. Some mornings it wouldn't turn at all, and he'd sit there working the steering wheel lock back and forth, thinking the column was the problem.

It wasn't the column. The key blade was rounded off on the cuts, so the sidebar wafers inside the GM ten-cut lock weren't seating. That slow wear is the kind of thing you don't notice until it fails on you at the wrong time.

I cut a fresh Strattec 5911588 blank to code, not copied from his worn key, but pulled from the lock data so the cuts were factory-spec again. Programmed the PK3+ transponder through the OBD port, cloned the OUC60270 remote, and tested all three buttons plus the ignition cycle. The lock turned like it was new.

He kept turning the key back and forth in the ignition a few times, just feeling the difference. Then he looked at his old key and kind of laughed, like he couldn't believe he'd been fighting that thing for months.

Whole job, about 35 minutes in the parking lot. He drove off with two working keys and no dealer appointment.

“I needed a car key replacement in Hillcrest and EZ Car Keyz helped me immediately. The technician programmed a new smart key right next to my car and tested every function before leaving. Fast, friendly, and very professional.”

“The dealership quoted me $600 for a new Honda key. EZ Car Keyz did it for $225, same day, cut and programmed at my house. Works perfectly. Everyone should know this is an option.”

Hummer H3 Mobile Service FAQ

Real costs, no dealer surprises

How many buttons does a 2010 Hummer H3 key have and what do they do?
Three buttons: lock, unlock, and rear hatch release. The key uses the OUC60270 or OUC60221 remote head at 315 MHz. All three are integrated into the key head, so there's no separate fob to carry. When I make a replacement, every button gets programmed and tested on your actual vehicle before I leave. If the hatch release doesn't respond, that can point to a liftgate actuator issue on these, not the key, so I check for that too.
What is a transponder key and why does my H3 need one?
Why does the dealer cost so much more for a replacement H3 key?
My SECURITY light stays on and the H3 won't start. Is the key bad?
Can I program a new 2010 H3 transponder key myself at home?
