🔧 PRO TIP
The 2008 H3 runs GM's PK3+ (Passkey 3+) immobilizer system with a Megamos ID13 transponder chip embedded in the key blade. The transponder key is separate from the remote. Your remote fob (FCC ID: L2C0007T, GM part 15913420) uses a CR2032 and handles locks only. It does not start the car. If the key turns but the engine cranks and dies after two seconds, that is the PK3+ killing the fuel injectors because it does not see the right chip. The problem is the transponder, not the battery in your remote.

2008 Hummer H3 Transponder Key Replacement - Fast, Affordable & Professional

Got a call from a guy at Pacific View Mall in Ventura. He had been inside one of the stores, came out, and his 2008 H3 was just sitting there with zero keys. Lost them somewhere between the food court and the parking structure. He already called the dealer and got the speech: tow it in, wait three to five business days for the key to arrive, then pay a big number.

He did not want to tow anything.

I pulled up, confirmed the VIN, and got to work right there in the lot. Cut a new key blade to factory spec using the code, then seated a fresh Megamos ID13 transponder chip. Plugged into the OBD-II port under the dash and ran the PK3+ all-keys-lost procedure. That clears every old key from the body control module and registers the new transponder from scratch. Once the immobilizer accepted the chip, I programmed his L2C0007T remote for lock, unlock, and hatch.

Then the part that matters: testing. Key turns, engine catches and stays running, no theft deterrent light on the cluster, no DTC codes stored. Remote locks from 30 feet away, unlocks clean, hatch pops.

He sat in the driver's seat for a second and just kind of exhaled. Like the whole afternoon had been holding its breath.

Whole thing took maybe 40 minutes. He drove out of that parking structure on his own, same day, for a fraction of what the dealer quoted him.

“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.”

“My key fob stopped working while I was at Oxnard Harbor and I thought I was going to need a tow. EZ Car Keyz showed up fast, programmed a new fob, checked everything carefully, and made sure the car was fully functional before leaving.”

Hummer H3 Mobile Service FAQ

Real costs, no dealer surprises

What battery does the 2008 Hummer H3 key fob remote use?
CR2032. It is a standard coin cell you can grab at any pharmacy or auto parts store. Pop the fob case apart with a flathead or a coin, swap it, and snap it back. The CR2032 only powers the remote buttons for lock, unlock, and hatch. It has nothing to do with starting the car. That is handled by the transponder chip inside the key blade, which has no battery at all.
What is the FCC ID for the 2008 Hummer H3 remote and what does it mean?
How long does a replacement key for a 2008 Hummer H3 take on site?
My 2008 H3 cranks but dies after a couple seconds. Is that the key?
Can I program a new transponder key for my 2008 H3 myself at home?
