2021 Mazda 3 Smart Key Replacement - Fast, Affordable & Professional

Lock decoding means I read your car's lock to create a key without drilling, without breaking anything, and without replacing the cylinder. The car looks exactly the same when I leave.

An Uber driver between rides on a frontage road pulloff near Scripps Ranch had his key snap inside the door lock of his 2021 Mazda 3. The blade broke clean off from years of heavy use. Another locksmith he called told him the lock would need to be drilled. New cylinder, new key, pushing $450.

I used my VVDI2 to read the transponder data from the broken key head since the chip was intact. Then I used my MAZ24 Lishi to extract the broken blade fragment without scratching the wafer surfaces. Once extracted, I decoded the lock and cut a fresh blade to exact depths. His remote, FCC ID WAZSKE11D01, was a 4-button unit that I rebuilt into a fresh shell with the salvaged chip.

No drilling, no cylinder replacement. His total was $285. The other locksmith wanted $488 or more. Destructive entry should be a last resort.

“I called over 40 locksmiths trying to get a key made for my Audi A6 and nobody could do it. Tim made it easy, fast, and affordable. He showed up with a smile and got the job done without any stress. Absolute wizard with keys.”

“My Chevy key snapped while I was running errands in North Oxnard. He removed the broken piece from the ignition, cut a new blade, programmed the transponder, and tested everything thoroughly. The whole job was smooth and professional. Best automotive locksmith I have used.”

“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.”

Mazda 3 Mobile Service FAQ

Real costs, no dealer surprises

What is the cheapest way to handle all-keys-lost on my Mazda?
Call a mobile locksmith, not the dealer. Mazda dealer AKL quotes run $600 to $900 before you add towing, and they may not get to it the same day. A CX-5 owner facing $898 at the dealer had a mobile locksmith do the entire job for $400 on site. We come to your location in San Diego, cut the key, reset the immobilizer, program the transponder and remote functions, and test it all before we leave. No tow, no overnight, no dealer markup.
Can you delete lost or stolen keys from my Mazda so they no longer work?
Does my Mazda smart key have a hidden emergency blade?
How many buttons does the 2021 Mazda 3 key have?
