🔧 PRO TIP
The 2011 Yaris remote head key (MOZB41TG) uses a Texas Instruments TMS37126 / 4D-67 transponder chip inside the key head. That chip talks to the immobilizer ECU through Toyota's standard 4D encryption, not the newer 80-bit H chip that showed up later. If your key turns the ignition but the engine cranks and dies right away, the immobilizer light on the dash (the little car with a key icon) will stay solid or blink. That means the 4D-67 chip is not being read. Before assuming the worst, pull any extra fobs, AirTags, or gate remotes off the ring. RF clutter on the keychain can block the transponder signal at the antenna coil around the ignition cylinder.

2011 Toyota Yaris Remote Head Key Replacement - Fast, Affordable & Professional

A guy near the Omer Rains Bike Trail in Ventura lost his only Yaris key somewhere between the sand and the parking area. Looked for close to an hour, checked with people nearby, retraced his steps twice. Nothing. His 2011 Yaris was sitting in the lot with no way to open it.

I started with my TOY43 Lishi tool. The 2011 Yaris runs the standard Toyota TOY43 keyway, and the Lishi picks and decodes each wafer position inside the door cylinder so I get exact cut depths without the original blade. Took maybe eight minutes to read all ten wafers.

Once I had the mechanical side done, I cut a new remote head key blank on my mobile machine, then connected through the OBD-II port to reset the immobilizer ECU. On this generation Yaris, the 4D-67 transponder registration requires a timed seed-key handshake with the immobilizer module. Old key data gets wiped, new chip gets written in. After that I synced the three remote buttons: lock, unlock, panic.

He was sitting on a bench watching the whole thing. When the engine fired, he just sort of nodded and said "huh." Like he expected it to be harder than that.

The dealer would have meant a tow and a wait measured in days. This was about 50 minutes, start to finish, right there in the lot.

Toyota Yaris Mobile Service FAQ

Real costs, no dealer surprises

I lost my only key for a 2011 Toyota Yaris. Can you make one without the original?
Yep. All-keys-lost on the 2011 Yaris is a standard field job for me. I decode the TOY43 lock cylinder to get the cut data, make a new MOZB41TG remote head key, then connect through OBD-II to reset the immobilizer ECU and register the fresh 4D-67 transponder chip. Old key data gets erased so whatever is lost out there can never start the car. The remote buttons get synced at the same time. Usually takes around 45 to 55 minutes from arrival to engine running.
Is a mobile locksmith cheaper than the Toyota dealer for a 2011 Yaris key?
Does your Yaris key replacement include cutting, programming, and the remote?
My 2011 Yaris key turns the ignition but the engine cranks and immediately dies. What is going on?
Can I buy a 2011 Yaris remote head key online and program it myself?
