Mercedes-Benz C-Class key service
The Mercedes-Benz C-Class may use different key systems across different years. Older models may use a transponder chip key or remote head key, while newer models may use a smart proximity key with push-button start. Before quoting, we confirm the year, trim, ignition type and whether any working key is available.
| Situation | Recommended approach |
|---|---|
| Need a spare key | Make it while one key still works when possible. |
| All keys lost | Verify ownership, decode/cut key and program when supported. |
| Remote not working | Check battery, shell, button condition and programming. |
| Smart key lost | Confirm push-start system and correct proximity key type. |
