Mazda 3 key replacement in McKinney, Plano, Frisco and nearby cities starts with knowing which key your year uses. 2010-2013 cars take a flip key or smart fob depending on trim, and 2014-2018 and 2019-2024 models run a proximity smart fob. Our Apex Locksmith Pros technician cuts and programs your Mazda 3 key on-site by VIN, wherever the vehicle is parked, and pairs it to the immobilizer so it starts the engine. One flat total is confirmed on the phone before dispatch, and a call-out fee is never added.

What Key Does the Mazda 3 Use?
Which key your Mazda 3 takes depends on the year. Early cars (roughly 2004-2009) use a bladed transponder key with a 4D-family chip that has to be programmed to the immobilizer. Mid-generation cars (about 2010-2018) run either a remote-head flip key or, on higher trims, a proximity smart fob for push-to-start. The current 2019+ Mazda 3 uses a proximity smart fob standard, with a laser-cut emergency blade hidden inside for the door. Every one of these needs the transponder or fob programmed to the car's immobilizer through the OBD port, plus the remote synced for lock/unlock. We handle both the cut and the programming with Autel IM508 gear, and Lishi picks if you're locked out with no working key.
The most common 3 call
A common one on the 2014-2018 Mazda 3 is the smart fob acting flaky: you have to be right on top of the car for it to detect, or push-to-start stops recognizing the key. Most of the time that's just the CR2025 coin cell inside the fob going weak, not the car. We pop the fob open, swap the battery, and confirm range. If the buttons themselves are mushy or cracked from years in a pocket, we can re-shell the fob and reprogram it instead of selling you a whole new unit.
Mazda 3 Key Fob FCC IDs
Flip your fob over: the FCC ID is printed on the back of the case. Find it below, or just read it to our dispatcher. It tells us the exact remote your Mazda 3 takes before the van rolls out.
| Years | Key type | FCC ID |
|---|---|---|
| 2010-2013 | Flip key / smart by trim | KR55WK50121, KR55WK49383 |
| 2014-2018 | Proximity smart fob | WAZSKE13D01 |
| 2019-2024 | Proximity smart fob | WAZSKE13D03 |
Trim and market can change the fob, and several IDs often fit one model year. We confirm the exact part by VIN on every job, so a mismatched guess never reaches your driveway.

What Do Mazda 3 Owners Ask?
Straight answers for Mazda 3 owners in McKinney and nearby cities: which key your car uses, what to have ready and how on-site programming works.
Yes. We program Mazda 3 fobs and transponder keys on-site through the OBD port, same as the dealer does, no appointment or tow needed. We come to you and finish same day, for less than dealer pricing.
Yes, an all-keys-lost Mazda 3 is doable. We pull the cut from your VIN, get the door open with Lishi picks if needed, cut a fresh key or fob, and program it to the immobilizer on the spot. All-keys-lost takes a bit longer than adding a spare since the system has to be reset, but it's a roadside job, not a tow.
It depends on the year. An older transponder key is the cheapest; a push-to-start proximity smart fob on a newer Mazda 3 costs more because the fob hardware is pricier. Most jobs run well under what a dealer quotes once you add their programming fee and the trip. We give you the price up front before any cutting.
Yes. A 2013 Mazda 3 takes either the remote-head flip key or a proximity smart fob on push-to-start trims, both cut and programmed through the OBD port at the car. The early 2004-2009 chip keys and the all-fob 2019s are covered the same way. Every Mazda 3 year works; we just match the blank to your VIN.
It depends on the year. 2010-2013 Mazda 3: KR55WK50121 or KR55WK49383; 2014-2018 Mazda 3: WAZSKE13D01; 2019-2024 Mazda 3: WAZSKE13D03. The ID is printed on the back of your fob case. Trim and market can change it, so we confirm the exact part by VIN before the van rolls out.
Deciding where to go? Dealer, AutoZone or locksmith? compares cost, wait and what each one can program.
