2017 Toyota Yaris
Key Replacement - Save vs Dealer in Ventura County

2017 Toyota Yaris Smart Key Replacement - Fast, Affordable & Professional

Near Pierpont in Ventura, a woman called about her 2017 Yaris. She had one key, bought the car used, never got around to a spare. That one key finally gave out in the worst possible way: the housing cracked somewhere along the line, and the blade snapped off in the door lock cylinder. Half the blade inside the lock. The fob body in her hand. No backup, nowhere to be.

When I pulled up, the fragment was seated pretty deep. I extracted it clean without damaging the cylinder, then decoded the lock to confirm the cut. The circuit board and transponder chip inside the cracked housing were intact, which changes the job entirely. A working chip means I can read the existing key data and register new keys against it rather than running a full all-keys-lost procedure, which takes longer and costs more.

I rebuilt her original fob board into a fresh shell, cut two new blades to match, and programmed both keys at the vehicle through the OBD port. Tested every button, tested both keys at the ignition, walked the doors. Done in about 40 minutes at her parking spot.

She mentioned she had called the dealer first. The quote she got assumed a full all-keys-lost job regardless of whether the chip was recoverable. That is not always the right call, and it is not the cheapest one either. If you still have the broken key, even just pieces of it, bring it. The chip surviving a cracked housing is more common than people expect, and it can change what the job looks like.
