2021 Mazda 3 Smart key Replacement - Fast, Affordable & Professional
Mazda uses a transponder immobilizer system on every model since the early 2000s. On older Mazdas, it's a chip in the key head, usually a 4D63 or ID46, that communicates with a coil around the ignition. On newer push-to-start models, the smart fob uses an ID49 chip that talks wirelessly to antennas in the doors and cabin. Either way, the car won't start unless the chip sends back the correct encrypted code.
A freelance graphic designer at the smoothie shop in Camarillo thought only the dealer could handle the programming on his 2021 Mazda 3. He needed a spare smart key and the dealer quoted 451. He assumed that was the only path because of "the computer chip stuff." A friend who'd used me before passed along my number.
I brought my Smart Pro to his car. It reads the immobilizer PIN, handles the security wait, and registers new keys to the keyless module. His smart key, FCC ID WAZSKE11D01, was a 4-button smart fob.
His spare was programmed and tested in about 30 minutes including the security wait. Total was around 262. Same chip, same programming, same result as the dealer.

“I had two Subaru key fobs made and Marco provided excellent service. He stayed persistent through multiple part orders to make sure everything was correct. Very thorough, punctual, and great communication throughout.”
“I called EZ Car Keyz to unlock my truck, make a key, and sync a new key fob. They were at my location within minutes and handled everything fast and friendly. Prices were great and the service was excellent.”
“This is the only locksmith anyone should ever call. I am still shocked at how fast he arrived and the price was hundreds less than other quotes I received. Honest, professional, and extremely efficient.”
