2012 Toyota 4runner Remote Head Key Replacement - Fast, Affordable & Professional
A 4Runner owner in the East Ventura neighborhood called me around 2am. His only key had stopped communicating with the truck. The 4Runner was sitting in his driveway, and he was already on his phone pricing tow trucks and looking up dealer hours for the morning.
I told him to stay put.
I drove out, connected my programmer to the OBD-II port, and started the Toyota all-keys-lost procedure. On the 2012 4Runner, the immobilizer ECU runs that 4D-72-G transponder protocol, so the tool reads the seed data off the immo box, calculates the encryption password, and walks through key registration from scratch. The whole process has a timed security countdown built into it. You just wait it out.
His new remote head key, HYQ12BBY with part number 89070-42660, got cut on the spot, transponder paired, and remote buttons synced. Three-button setup: lock, unlock, panic. I tested every function at the doors, the hatch, the ignition cycle. All clean.
He stood in the driveway in gym shorts watching the whole thing. When the engine turned over, he just nodded like he didn't quite believe it was done.
No tow. No waiting in a dealer lounge for two days. The whole job was wrapped up by about 3am, for a fraction of what the dealership route would have run him.
