For years Mazda was partly owned by Ford and shared some of its key systems. That history is why many older Mazdas are easy for a locksmith, while newer ones use Mazda's own smart keys.
Your Key by Era
| Years | Key system | What it means |
|---|---|---|
| Late 1990s to late 2000s | Chip key | Many models used a system related to Ford's. Some allow owner programming with two working keys. |
| 2000s to 2010s | Flip key | Common on Mazda3, Mazda6 and CX models. |
| 2010s to now | Smart key push-start | Most newer models. |
What a Locksmith Can Usually Do
Spares and all-keys-lost jobs on most Mazdas are routine for a mobile locksmith.
When the Dealer Is the Better Call
Rarely required. Some of the newest models may need newer tools.
Tips Worth Knowing
- If you have two working keys on an older Mazda, check the manual for at-home programming of a third.
- Flip key hinges and shells wear out. A new shell is cheaper than a new key.
- Smart key fobs hide a metal key for the door. Find the release now.
