Hummer Key Fob Programming
Neither Hummer we cover can be programmed at home. That's the H2 for 2008 and 2009 and the H3 from 2006 to 2010, seven model years in all, so a new key or remote means a locksmith or dealer. Both use a separate remote alongside a chip key, and every fob takes a CR2032. The model pages list the FCC ID and part number for each year.
Choose your Hummer model for programming steps, the battery it uses, and the correct replacement fob with FCC ID and part number — 7 model years across 2 models.
A brass dot marks models with verified replacement-fob data (FCC ID + part number).
Can you program a Hummer key fob yourself?
Not at home. None of the 7 model years we cover has an owner programming procedure, so every Hummer fob and key has to be programmed by a locksmith or dealer with a diagnostic tool. The model pages still list the exact replacement fob and battery for each year.
What battery does a Hummer key fob take?
Every Hummer fob we cover takes a CR2032.
| Battery | Model years | Models |
|---|---|---|
| CR2032 battery on Amazon | 7 | H2 (2008–2009); H3 (2006–2010) |
Hummer key types
The replacement keys we've matched to Hummer models fall into 2 types. A model year can take more than one, which is why the model pages list each option with its FCC ID.
- Remote 2006–2010
- A separate key fob that only handles locking and unlocking.
- Transponder Key 2006–2010
- A cut metal key with a chip in the head. No buttons.
What Hummer key programming costs
US price ranges for the key types above, with a working key on hand. Losing every key costs more, $200–$500 at a locksmith for a basic fob or transponder key.
| Key | Locksmith | Dealer |
|---|---|---|
| Basic remote, working key on hand | $50–$150 | $100–$250 |
| Transponder or remote-head key | $75–$200 | $150–$350 |
