Key Replacement - Save vs Dealer in Ventura County

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

Oxnard Shores is a weird place to lose your only car key. It's a tight little coastal neighborhood - a few blocks of houses, the beach, and not much else. Not exactly where you want to be stranded.

A guy had parked near the water and spent the better part of an afternoon out on the sand. When he got back to his 2019 CX-3, the fob was gone. Not in his bag, not in his jacket, not anywhere he'd been. He called the dealer first. Next available appointment was four days out, and they wanted him to tow the car in before they'd even talk about it.

He called me instead.

I drove out to Oxnard Shores and found the CX-3 sitting exactly where he'd left it - locked, no key, no way in. I used a Lishi tool to pick the door open and decode the blade profile from the lock cylinder directly, so I had the exact cut data without needing the original key. Then I connected through the OBD port and ran the all-keys-lost procedure. Mazda's system on this generation has a security delay timed into the reset - you just sit and wait it out. There's no skipping it.

Once the wait cleared, I programmed two new smart fobs and cut both blades to match the decoded profile. Both keys started the car. Both unlocked the doors from the lot. He walked away with a working vehicle and a spare, same afternoon, no tow involved.

The dealer would have been four days, a flatbed, and a lot more money. He saved a good chunk and got back on his feet the same day he called.
