A smart key is the type of key your 2017 Mazda CX-3 uses. It contains a programmed chip that communicates with your vehicle's Mazda immobilizer system to verify it is an authorized key before the engine will start. It also has 3 buttons for remote lock, unlock, and other functions depending on your trim level. Without proper programming, even a perfectly cut key will not start your Mazda because the immobilizer will reject it.

Q: How much does the Mazda dealer charge vs a locksmith?

Mazda dealers typically charge between $400 and $750 for a smart key replacement. That breaks down to roughly $200 to $400 for the fob, $20 to $100 for cutting, and $120 to $300 for programming and diagnostic labor. One CX-30 owner was quoted $240 for the key and almost $300 for programming, totaling over $540 for a single fob. A mobile locksmith like EZ Car Keyz handles the same job with professional equipment for a fraction of that. Your 2017 Mazda CX-3 smart key runs $257 with us, fully programmed and tested on site.

Q: What is the FCC ID for the 2017 Mazda CX-3 key?

The FCC ID is WAZSKE13D01, WAZSKE13D02. This is the identifier printed on the back of your key fob that tells us exactly which key your vehicle requires. It ensures we match the correct blank, the correct chip frequency, and the correct remote protocol so the key programs correctly on the first attempt. Mazda is especially picky about FCC ID matches. Locksmiths report that using the wrong remote ID triggers a key error on the dash and the programming will fail entirely.

Q: Do you offer a warranty on the key?

Yes. Every key we make comes with a warranty covering both the hardware and the programming. Mazda owners online warn about cheap aftermarket keys where the buttons died within 24 hours or the key warning light stayed on permanently after programming. One Mazda6 owner paid a locksmith for a generic fob and had it fail the next day, then had to fight for a refund. When you go with EZ Car Keyz, the key is tested on the spot before we leave, and if there is ever an issue after that, we take care of it.

2017 Mazda CX-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 Topa Topa Brewing Company had his key snap inside the door lock of his 2017 Mazda CX-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 WAZSKE13D01, was a 3-button unit that I rebuilt into a fresh shell with the salvaged chip.

No drilling, no cylinder replacement. His total was 257. The other locksmith wanted 443 or more. Destructive entry should be a last resort.

Common Mazda CX-3 Pricing Questions

What it costs and what you get

Why is Mazda key replacement so expensive?▼

Modern Mazda keys are not just pieces of metal. A smart key has an encrypted transponder chip, communication with your vehicle's immobilizer, and remote functions that all need to be programmed to your specific VIN. Newer Mazdas use a security server system called MDARS that requires authorized access to generate one-time codes for programming. That is why a Mazda dealer can quote $500 to $750 for a single smart key. The technology is real, but the dealer markup on top of it does not have to be.
