2019 Mazda CX-3
No Working Key - No Problem in Ventura County

Q: How much more does all-keys-lost cost vs a spare?

Significantly more, on any Mazda. When you still have one working key, adding a spare is a straightforward programming job. When all keys are lost, the immobilizer needs a full reset and reprogramming from scratch, and some Mazda systems require two new fobs to complete the procedure. A 2022 CX-5 owner was quoted $900 at the dealer for an all-keys-lost job with two fobs. Forum commenters confirmed that $900 "sounds about right" for dealer AKL on a Mazda smart key vehicle. The best advice is to get a spare made while you still have a working key.

Q: Are aftermarket Mazda keys cheaper and do they work?

Aftermarket keys are cheaper upfront, but on Mazdas the results are mixed. A CX-5 owner bought an aftermarket fob for $70, had a locksmith program it for $70, and reported two years of trouble-free use. But a Mazda6 owner got a generic aftermarket fob that died within a day, and a Mazda3 owner ended up with a permanent key warning light from an aftermarket fob. Mazda is notoriously selective about keys. We carry OEM spec keys that are tested and verified for your specific Mazda model so you are not gambling on compatibility.

Q: How many buttons does the 2019 Mazda CX-3 key have?

Your 2019 Mazda CX-3 key has 3 buttons. The button count helps identify exactly which fob your vehicle uses, since Mazda sometimes uses different remotes across trim levels of the same model. When you call us, having this detail along with your year, make, and model helps us confirm the right key before we head out so there are no surprises when we arrive.

Q: Are there hidden fees I should watch out for?

Not with us. Our price is our price: key, cut, program, mobile service, all in. But Mazda dealers are a different story. One Miata ND owner posted an invoice showing four separate line items: $200 for the fob, $30 for the inner key, $140 for programming, and $150 for "service labor," totaling $558. Another owner on Reddit broke down a $725 Mazda dealer quote as $300 to $400 for the fob, $100 for the physical key, $100 for cutting, and $220 for programming alone. With EZ Car Keyz, $247 is the total. Period.

2019 Mazda CX-3 Smart key Replacement - Fast, Affordable & Professional

No key at all? I get these calls all the time. On newer Mazda push-to-start models, all-keys-lost requires two new keys programmed in one session before the car will start. That's a Mazda system requirement, not a locksmith upsell.

A birdwatcher at the nature preserve lot outside Oxnard lost his only key somewhere on the trail. He searched for half an hour, checked with the ranger station, nothing. His 2019 Mazda CX-3 was sitting in the lot and he had no way to open it. He figured it was stuck until a tow could drag it to the dealer. I told him I could be there that afternoon.

I started with my MAZ24 Lishi to pick the door open and decoded each wafer position for exact cut depths without the original. Then I connected through OBD, ran the all-keys-lost procedure with the 7-minute security wait, and programmed two new smart keys. His smart key, FCC ID WAZSKE13D01, was a 3-button smart fob.

His car started in the same dirt lot. Total was around 247. Dealer wanted 428 plus a tow and a weekday appointment.

“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.”
