🔧 PRO TIP
The 2016 Yaris remote head key (HYQ12BBY) uses a Texas Instruments TMS37126 "4D-67" transponder chip, not the newer 8A/H chip Toyota moved to later. That matters because 4D-67 cloning is reliable and fast, meaning an all-keys-lost job does not need a Toyota server connection. The CR2016 battery in the remote head is smaller than most Toyota fobs use. It drains faster than a CR2032, so if your lock/unlock range drops, swap it before assuming the worst.

2016 Toyota Yaris Remote Head Key Replacement - Fast, Affordable & Professional

Over near Arroyo Verde Park in Ventura, a guy flagged me down from the shoulder. Well, not flagged, he had already called. But he was standing outside his 2016 Yaris holding two pieces of key like a broken wishbone.

The blade snapped clean in the ignition cylinder. Half still jammed in, half in his palm. He told me another locksmith quoted him for a full ignition replacement, drilling included. That is a real job on some cars. This was not one of them.

I grabbed my TOY43AT Lishi, slid it into the keyway alongside the broken fragment, and worked the piece out without touching the wafers. Toyota's TOY43 keyway on these third-gen Yaris sedans is narrow but predictable. Once the fragment cleared, I decoded all eight wafer positions from the cylinder itself, no guessing, no key code lookup needed.

Cut a fresh blade on my HPC machine, paired it with a new 4D-67 transponder shell, and programmed the chip through the OBD port. The whole immobilizer handshake took about ten seconds. His remote (HYQ12BBY, part number 89070-42660) was fine since it is a separate piece on these, not built into the key head. I just handed him back a working key.

His original ignition cylinder, untouched. No drill marks, no replacement parts, no dealer visit. He kept looking at the lock like he expected to see a scratch.

“My key fob stopped working while I was at Oxnard Harbor and I thought I was going to need a tow. EZ Car Keyz showed up fast, programmed a new fob, checked everything carefully, and made sure the car was fully functional before leaving.”

Toyota Yaris Mobile Service FAQ

Real costs, no dealer surprises

Why is replacing a 2016 Toyota Yaris key so expensive at the dealer?
The key itself is not just metal. The HYQ12BBY remote head key has a 4D-67 transponder chip that has to handshake with the immobilizer ECU (part number 89780-52481 on most Yaris sedans) before the engine turns over. The dealer charges for the blank, cutting, and a separate programming labor line. Some add a diagnostic fee before they even start. Owners on YarisWorld and ToyotaNation regularly report dealer quotes north of what the whole job should cost. I handle the same programming through OBD with professional tools, on site, for way less.
What exactly is a remote head key, and is that what my 2016 Yaris uses?
