Key Replacement - Save vs Dealer in Ventura County

2015 Toyota 4runner Remote Head Key Replacement - Fast, Affordable & Professional

She was at a sushi place in Ventura near the Loma Vista neighborhood when her bag got swiped off the chair next to her. Keys, wallet, phone, all gone. She borrowed the server's phone and called the police, then her husband, then me.

Her 2015 Toyota 4Runner was sitting in the lot with zero keys. The dealer told her husband three to five business days, the car had to be towed in, and they recommended rekeying. The estimate was ugly.

I got there that evening. All-keys-lost is a different process than adding a spare. Adding a key means the car already trusts one key and just registers another. All-keys-lost means I wipe the key memory through the OBD port and start fresh, so the stolen key is erased from the immobilizer entirely. I used the IM608 to access the 4Runner's H-chip transponder system, cleared the old key data, and registered two new HYQ12BBY remote head keys from scratch. Decoded the lock cylinder, cut both emergency blades, and had both keys starting the car before the police report was even filed.

She drove home that night. The stolen key can still physically fit the door lock, but the immobilizer will not let the engine fire. That is the first thing I tell people in her situation. The moment I wipe the key memory, the old key is dead to the car.
