2010 Mazda 3
Low-Cost Key Made On-Site in Ventura County

Q: How does mobile key replacement work?

You call us and give us your year, make, model, and VIN. We confirm the right key for your 2010 Mazda 3 and give you a price on the phone. We come to your location with everything we need: the key blank, cutting tools, and professional programming equipment. We cut the key, program the transponder and remote functions to your vehicle, test everything, and hand you a working key. The whole process happens right next to your car. No tow truck, no waiting room, no second visit.

Q: What do I need to have ready when you arrive?

Just your vehicle, a valid photo ID, and proof of ownership like your registration. We pull the VIN from your dashboard or door jamb to verify the key specs. If you still have your Mazda key code tag, the small metal tag that came with your original keys, that can speed things up. Mazda dealers sometimes require additional steps or refuse to work on customer-supplied keys. We keep it simple so you can get back on the road faster.

Q: What battery does the 2010 Mazda 3 key fob use?

The 2010 Mazda 3 uses a CR2025 or CR1616 battery. You can find them at most auto parts stores or pharmacies for a few dollars. When we make a replacement key, we always install a fresh battery so you are starting with a full charge. If your current Mazda fob is losing range or acting inconsistent, try a new battery before assuming the key needs to be replaced.

Q: Can you come to my office or workplace?

Absolutely. A big chunk of our calls are to workplaces, office parking lots, and job sites across Simi Valley (Santa Susana area area). You do not need to take time off or leave work to deal with a key issue. We pull up, handle everything at your vehicle, and you go back to your day. One Mazda owner was told by the dealer to plan on "a couple hours" at the dealership and that it would "take half my day." With us you are looking at well under an hour at your vehicle and zero disruption to your schedule.

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

A first-year teacher at the community center lot in Simi Valley had just bought a used 2010 Mazda 3 from a coworker. Decent car, fair price, one key. She called the Mazda dealer and they quoted 466. On a new teacher's salary, that wasn't happening.

She found me online and asked if the dealer number was real. I told her it was. Dealers charge what they charge. But the same key, the same cut, the same programming costs 271 through me because I don't carry the same overhead.

I met her at the community center after school. Her 3 used an older remote-head key with a transponder chip inside. I used my VVDI2 to read the chip data from her existing key and clone it onto a fresh blank so the immobilizer accepted it without a full security reset. Her key's FCC ID was WAZX1T768SKE11A03, and I cut the blade from a decode of her door lock.

She drove home with two working keys for 271. That spare means if she ever loses one, the replacement is a quick add-a-key instead of all-keys-lost.

“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.”

“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.”

Do I need to bring my 2010 Mazda 3 somewhere for key replacement?▼

No. EZ Car Keyz is a fully mobile service. We come to wherever your vehicle is, whether that is your driveway, your job, or a parking lot in Simi Valley (Santa Susana area area). Mazda dealers require you to either drive in with a working key or tow the vehicle to their service bay. One CX-5 owner with no keys was facing a tow plus a $900 dealer bill just to get back on the road. We handle everything on site and you keep your vehicle the entire time.
