2018 Mazda CX-3
Key Replacement From Scratch in Ventura County

Q: Is a locksmith cheaper than the Mazda dealer?

On Mazdas, the gap between dealer and locksmith pricing is consistently large. A CX-5 owner was quoted $898 at the dealer for an all-keys-lost job and ended up paying $400 through a mobile locksmith. A CX-30 owner facing a $540 dealer quote got the same work done for $179 at a locksmith. Miata owners report the same pattern, with dealer quotes of $450 versus $180 at an independent locksmith. Most Mazda owners who go the locksmith route save 40 to 60 percent compared to what the dealer charges.

Q: Does the price include cutting and programming?

Yes. Our price covers everything: the key blank, cutting to your vehicle's specs, programming the transponder chip or smart key module, syncing remote functions, and testing before we leave. Mazda dealers often break this into four or five separate charges. One Miata ND owner posted a dealer invoice showing $200 for the fob, $30 for the inner key, $140 for programming labor, and $150 for service labor, turning a "key replacement" into a $558 bill with four line items. With us it is one price, everything included, done at your location.

Q: What battery does the 2018 Mazda CX-3 key fob use?

The 2018 Mazda CX-3 uses a CR2025 battery. You can pick one up 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 existing Mazda fob is acting sluggish or losing range, a new battery is the first thing to try before assuming you need a replacement.

Q: Do you charge a trip fee or service call fee?

No. The price we quote includes mobile service to your location anywhere in the Rice Avenue corridor neighborhood in Oxnard. There is no trip fee, no service call charge, no mileage add-on. Mazda dealers require you to bring the vehicle to them or tow it in, which can add $100 to $150 on top of what they already charge for the key. One CX-5 owner with no keys was looking at a tow plus a $900 dealer bill before they found a mobile locksmith who came to them for less than half that price.

2018 Mazda CX-3 Smart key Replacement - Fast, Affordable & Professional

People lose all their Mazda keys more often than you'd think. The most common story isn't dramatic. They bought the car used with one key, always meant to get a spare, and eventually that key cracks or falls out of a pocket.

A yoga teacher at the pilates studio lot in Oxnard had exactly that story at 5:15am before her dawn class. Her only remote-head key to her 2018 Mazda CX-3 cracked at the blade pivot and the blade snapped when she tried to open the door. Key head in one hand, blade stuck in the lock. Zero working keys.

I used my VVDI Key Tool to generate a fresh transponder chip while I extracted the broken blade with my Lishi. Because her old key's circuit board was still intact inside the cracked housing, I could read the chip data and skip a full all-keys-lost procedure. Her key, FCC ID WAZSKE13D01, was a 3-button remote-head that I rebuilt into a new shell with a fresh blade. I showed her the old chip so she could see it was still good.

She made her 6am class. Total was 252. Dealer wanted 436. If you still have the broken pieces, bring them.
