2020 Mazda CX-3 Smart Key Replacement - Fast, Affordable & Professional
An overnight ER tech near the Oxnard Transit Center called me around 11:15 on a weeknight. Her only smart key for the CX-3 had quit, the car was parked in her townhouse garage, and push-to-start just kept flashing "KEY NOT DETECTED" on the multifunction display. She was already looking up tow companies.
I told her to stay put.
When I got there, the fob was completely unresponsive. No button lights, no passive unlock when she grabbed the door handle. I popped the emergency mechanical key from the fob, got her driver door open, and plugged my Smart Pro into the OBD-II port under the dash.
The all-keys-lost procedure on this generation CX-3 reads the PIN off the KD5H keyless module, resets the immobilizer, and then makes you sit through a timed security countdown of about seven minutes. Nothing you can rush. I programmed two new WAZSKE11D01 fobs while the car sat in the garage, cut both emergency inserts on my mobile machine, and walked every function. Passive entry on all four doors. Trunk release. Push-button start from both the driver seat and the passenger seat, because sometimes the antenna coverage is uneven and one side picks up weaker.
She watched the whole thing from her kitchen doorway, holding coffee. Didn't say much until the engine turned over clean on the first press. Then she just nodded.
The dealer route would have meant a tow, a wait for parts, and way more money. She was back to normal before midnight.

“My car keys were stolen on a cold evening and Nick drove all the way out to Santa Barbara. He got into my car, made a new key, and charged $100 less than another company. Friendly, skilled, trustworthy, and genuinely caring. Nick is a hero.”
“Tim is a hero. He programmed a master proximity key for a newer Volkswagen that multiple locksmiths refused to touch. He spent hours until late at night making sure every function worked perfectly. The skill level here is incredible.”
“Very professional and extremely affordable. The price was literally about three times cheaper than what my dealership quoted me. Fast service and no stress at all. Highly recommend.”
