2018 Mazda 3 Smart Key Replacement - Fast, Affordable & Professional
A guy near Mission Oaks Park in Camarillo called me about his 2018 Mazda 3. His smart key fob had cracked open from a drop on his duplex driveway. The housing was split down the seam, buttons barely hanging on, the CR2025 half exposed. He said the dealer quoted him a full replacement fob, programmed, and told him that was the only fix.
What they didn't mention is that the WAZSKE13D01 internals were fine. The board inside, the circuit with the Mitsubishi transponder chip that talks to the car's keyless control module, was undamaged. Just the plastic shell was done.
I pulled up with my ACDP, read the keyless module data as a precaution in case anything went sideways, then carefully moved his working electronics into a new aftermarket shell. Fresh CR2025, reassembled, and started testing. Lock, unlock, trunk, panic. Then push to start with the fob in his pocket, then on the dash, then in the center console. All clean.
He stood there turning the new shell over in his hands like he was waiting for a catch.
No catch. His original programmed chip, his original key data, just a housing swap and a battery. Done in his driveway in about twenty minutes, for a fraction of what the dealer wanted to replace the whole unit.
