A Smart Key is the type of key your 2017 Mazda CX-9 uses. It contains a programmed transponder chip that communicates with your vehicle's Mazda immobilizer system to authorize the engine to start. It also has 4 buttons for remote lock, unlock, and other functions. Without proper programming, even a perfectly cut key will be rejected by your Mazda's security system. We program everything on site so your new key works exactly like the original.

2017 Mazda CX-9 Smart Key Replacement - Fast, Affordable & Professional

A retired bus driver on dialysis at the dialysis center in Poway called about his 2017 Mazda CX-9. He goes to treatment three times a week and getting to a Mazda dealer across town was a real problem. His aide was off that day and his only key's remote had stopped working. Getting to a dealer wasn't just inconvenient for him. It was a medical scheduling conflict.

I went to the dialysis center that morning. His car used an older edge-cut key with the MAZ24 keyway. I used my MAZ24 Lishi to decode the ignition lock and verify the wear, then cut a fresh blade and programmed the transponder through OBD. His separate remote, FCC ID WAZSKE13D01, was a 4-button unit that I paired at the same time.

He didn't leave the center. Didn't miss treatment. Total was $247 for a working key and remote. Dealer quoted $428 plus the problem of getting there.

Mazda CX-9 Mobile Service FAQ

Real costs, no dealer surprises

Do I have to go to the Mazda dealer to get a replacement key?▼

No. A qualified mobile locksmith can cut and program a Smart Key for your 2017 Mazda CX-9 right where the vehicle sits. Mazda owners often assume the dealer is the only option because Mazda uses a server-based security system on newer models. But locksmiths with the right tools and credentials handle the same programming. Some Mazda owners have even discovered that their dealer outsources key work to mobile locksmiths anyway, which means you could have called that locksmith directly and saved money.
