Emergency 2016 Mazda CX-3 key fob made from scratch by EZ Car Keyz Ventura CA
🔧 PRO TIP
The 2016 CX-3 smart fob runs a CR2025, not the CR2032 that fits half the other fobs in the drawer. Easy mix-up. If you swap in a CR2032 it'll seat wrong, make intermittent contact, and you'll think the fob is dying when the battery is just slightly proud of the contacts. The fob itself is shared across several Mazda models from this generation, which means parts are easy to source and most locksmiths with Mazda coverage already know the system well. Three buttons: lock, unlock, and one more. The emergency insert blade lives inside the fob body and gets you in the door if the fob goes completely dead. Know where that release tab is before you need it in a parking lot.

2016 Mazda CX-3 Smart Key Replacement - Fast, Affordable & Professional

She was at the outlets over near River Park when her purse got taken right out of her shopping cart. Keys, wallet, phone, all of it. She borrowed a phone from a store clerk, called her husband, then the police, then me.

Her 2016 CX-3 was sitting at home in the garage with zero keys. The Mazda dealer told her husband they could order parts but needed three to five business days, plus they recommended towing the car in and doing a full security system reset so the stolen fob couldn't start the car anymore. The combined estimate was well over four hundred dollars before any tow bill.

I got there that evening while the police report was still being filed. All-keys-lost after a theft is a specific kind of job. The first thing you do is wipe the key memory entirely so the stolen fob is dead to that car. Then you register fresh fobs from scratch. I connected through the diagnostic port, cleared the old key data, and enrolled two new smart fobs. Cut both emergency blades to match the door, tested everything twice, walk-and-check on both doors, both handles, the start button, all three buttons on each fob.

She drove home that night with her daughter. The stolen fob is permanently locked out. Dealer wanted days and a tow. I was done before the officers left.

Mazda CX-3 Mobile Service FAQ

Real costs, no dealer surprises

What is the cheapest way to replace my 2016 CX-3 key?
Call a mobile locksmith before you call the dealer. Mazda dealers price smart key jobs high because they factor in parts lead time, shop labor rates, and in some cases a mandatory tow if you have no working key to drive the car in. With EZ Car Keyz you skip all of that. I come to you in River Park, Wagon Wheel, wherever the car is sitting, and the job gets done on site. You get pricing when you call, but it will be a fraction of what the dealer quoted you.
How much harder is all-keys-lost compared to just adding a spare?
Do aftermarket CX-3 fobs actually work, or should I stick with OEM-spec?
My CX-3 shows a key warning on the dash but the fob starts the car fine. What's going on?
I have a spare CX-3 fob I bought online. Can I program it myself?
