🔧 PRO TIP
The 2010 Mazda 3 smart key (FCC ID: WAZX1T768SKE11A03) has a transport/sleep mode that kills relay theft. Press the lock button four times quickly, then hold lock until the LED flashes. That shuts down the passive polling between car and fob, so a relay amplifier gets nothing. Re-activating is just pressing any button. Good habit if you store the key near your front door or on a hook by a window.

2010 Mazda 3 Smart Key Replacement - Fast, Affordable & Professional

A first-year teacher at the community center lot in the Santa Susana area had just bought a used 2010 Mazda 3 from a coworker. Decent car, fair price, one key. She called the Mazda dealer and got the number she was afraid of. On a new teacher's salary, that was not happening anytime soon.

She found me online and asked if the dealer quote was real. I told her it was. Dealers charge what they charge. But the same result costs a good chunk less through me because I am not running a service bay with that overhead.

I met her after school in the lot. Her 3 had the second-gen (BL) advanced keyless system with the WAZX1T768SKE11A03 smart key, part number BBY2-67-5RY. The system runs Mitsubishi Electric transponder authentication on the PCB board inside the fob. I registered a new smart key through the OBD-II port using my diagnostic tools and cut the emergency insert blade from a decode of her driver door cylinder.

She sat on the bench grading papers the whole time. Looked up when I handed her two working keys, said "that's it?" and went right back to her stack.

That spare key means if she ever loses one, the next replacement is a simple add-a-key job instead of a full all-keys-lost procedure, which takes longer and costs more on any car.

Save vs the Dealer on Your Mazda 3 Key

Get your key for hundreds less than the dealer. Same quality, same result, better price.

“I needed a car key replacement in Hillcrest and EZ Car Keyz helped me immediately. The technician programmed a new smart key right next to my car and tested every function before leaving. Fast, friendly, and very professional.”

“The dealership quoted me $600 for a new Honda key. EZ Car Keyz did it for $225, same day, cut and programmed at my house. Works perfectly. Everyone should know this is an option.”

“A+ service at an even better price. Tim was a lifesaver. I lost my original and only key for my Audi and he was willing to come to my location at 8pm the same day. He worked fast, communicated clearly, and made sure everything worked before leaving.”

Mazda 3 Mobile Service FAQ

Real costs, no dealer surprises

Do I need to bring my 2010 Mazda 3 somewhere for a new smart key?
No. I come to you. Wherever your car is in Simi Valley, whether that is your driveway, your job, or a parking lot in the Santa Susana area, I show up with the key blank, cutting equipment, and programming tools. Mazda dealers need you to either drive in with a working key or have the car towed to their service bay. I have seen owners quoted for a tow on top of the key replacement just to get back on the road. I handle everything on site and you keep your car the whole time.
How does mobile smart key replacement actually work on my Mazda 3?
What do I need to have ready when you arrive for key service?
My 2010 Mazda 3 says "KEY IS NOT DETECTED" but the fob is right here. What is going on?
Can I just get a copy of my existing Mazda 3 smart key without dealer involvement?
