🔧 PRO TIP
The 2012 Yaris remote head key (MOZB41TG) uses a Texas Instruments TMS37126 / 4D-67 transponder chip, not the newer Toyota H or smart key system. This is a traditional turn-key ignition with a physical chip in the key head. The CR2016 battery only powers the lock/unlock/panic buttons. If the battery dies, the car still starts fine because the immobilizer reads the 4D-67 chip passively. Dead remote buttons do not mean a dead key.

2012 Toyota Yaris Remote Head Key Replacement - Fast, Affordable & Professional

Got a call around 2am from a guy over near Ventura River Trail. His 2012 Yaris was sitting in the driveway and his only key had snapped at the blade, right where the plastic meets the metal. The transponder head was in his hand and the blade was stuck in the ignition cylinder.

He had already looked up dealer hours. Earliest appointment was four days out, and they wanted him to tow it in since the blade was jammed.

I told him to hang tight. Pulled the broken blade out of the cylinder with extraction tools, took maybe ten minutes. Then I set up on the hood. The 2012 Yaris runs Toyota's 4D-67 transponder on the 89070-21050 remote head key. I cut a new TOY43 blade by code, cloned the 4D-67 chip from his broken key head, and assembled the new MOZB41TG shell with a fresh CR2016 for the remote buttons.

Then I programmed the remote function through OBD using the T-Code. Lock, unlock, panic, all three buttons confirmed. Tested the transponder start twice cold.

The part that stuck with me: he kept holding the old broken key like he wasn't ready to let go of it. I told him it was dead weight now. He dropped it in a drawer and went back to bed.

Whole thing was done on site for a fraction of what the dealer quoted, and he never left home.

Toyota Yaris Mobile Service FAQ

Real costs, no dealer surprises

What is the cheapest way to replace my 2012 Toyota Yaris key?
Call a mobile locksmith before the dealer. The 2012 Yaris uses part number 89070-21050, a 3-button remote head key with a 4D-67 transponder chip. At the dealer, you are paying separately for the key shell, the blade cut, the transponder programming, and sometimes a diagnostic fee on top of that. Yaris owners on Toyota forums regularly report dealer totals that make them wish they had called around first. I show up, cut the TOY43 blade, program the chip and remote, and hand you a working key on the spot for way less.
How much more does all-keys-lost cost compared to getting a spare made?
Are aftermarket Toyota Yaris keys reliable, or should I stick with OEM?
My 2012 Yaris key remote stopped locking and unlocking. Does the whole key need replacing?
Can I program a new 2012 Yaris transponder key myself with a DIY method?
