🔧 PRO TIP
The 2017 CX-3 runs the same WAZSKE13D01 smart key found on the Mazda3, Mazda6, and CX-5 from that era. All share Mazda's Mitsubishi Electric transponder system with a 128-bit AES chip on the ID49 (PCF7953P) platform. A weak CR2025 will throw "KEY IS NOT DETECTED" on the dash and kill push-button start range before the remote buttons die. Swap the CR2025 first, but check the battery clip tension too, not just the voltage.

2017 Mazda CX-3 Smart Key Replacement - Fast, Affordable & Professional

Got a call from an Uber driver sitting in a pulloff near Topa Topa Brewing Company in Oxnard. His 2017 Mazda CX-3 had the emergency key blade snapped clean off inside the driver door lock. Years of heavy use, getting in and out between rides, and the thin MAZ24 blade just gave up.

He had already called another locksmith who told him the cylinder would need to be drilled out. New lock, new key, the whole deal.

I started with the broken fob housing. The ID49 chip inside was still intact, so I pulled transponder data with my VVDI2. Then I used my MAZ24 Lishi tool to extract the broken blade fragment without scoring the wafer surfaces. Once that was out clean, I decoded the lock to original depths and cut a fresh blade on site.

The WAZSKE13D01 shell was cracked from the break, so I transferred the board and chip into a new 3-button housing, part number KDY3-67-5DY. Tested lock, unlock, trunk, push-button start, walked to every door. All good.

He sat on the curb the whole time watching. When I handed it back he turned it over a couple times like he was checking if it was really his. Same key data, same programming, fresh shell and blade.

No drilling. No cylinder swap. No trip to the dealer. He was back picking up rides in under an hour.

Mazda CX-3 Mobile Service FAQ

Real costs, no dealer surprises

Why is a 2017 Mazda CX-3 smart key replacement so expensive at the dealer?
It is not just a key. The WAZSKE13D01 carries an ID49 transponder chip running 128-bit AES encryption that has to handshake with the CX-3's immobilizer module. Newer Mazdas including the 2017 CX-3 require Mazda's MDARS security server to generate a one-time registration code before a new key can be paired. The dealer has to pay for that server access, pay the parts counter price for the fob, cut the blade, then bill shop labor on top. That stack adds up fast. A mobile locksmith with the right tooling and server access handles the same process for way less.
