2011 Toyota 4runner replacement key fob with no original from EZ Car Keyz Ventura CA
🔧 PRO TIP
The 2011 4Runner remote head key (HYQ12BBY) uses a Texas Instruments TMS37126 "4D-67" transponder chip and the TOY43 keyway. The battery is a CR2016, not a CR2032. Owners mix those up constantly because they look similar but the CR2032 is thicker and will crack the fob shell or bend the contacts. If your remote range drops but the mechanical key still starts the engine, that is a dead CR2016, not an immobilizer problem. Swap the battery before you panic.

2011 Toyota 4runner Remote Head Key Replacement - Fast, Affordable & Professional

A guy in Ventura, over in the College Area, lost his only 4Runner key somewhere between the sand and the parking area near the beach. Looked for close to an hour, checked with the lifeguard station, retraced his steps twice. Nothing. His 2011 4Runner was just sitting in the lot with no way in.

I started with the TOY43 Lishi tool. It picks and decodes the lock cylinder by reading each wafer position, gives me exact bitting depths without the original blade. Clean decode, no drama.

Mechanical side done, I moved to the immobilizer. Connected through the OBD-II port to the 4Runner's immo computer, board number 89784-35150, and ran the all-keys-lost reset sequence to wipe the old 4D-67 registration and write in the new HYQ12BBY. Toyota's fifth-gen 4Runner uses a challenge-response protocol between the transponder and the immo ECU, so the chip has to be virgin or factory-reset before the system accepts it. That part is just software and timing.

Cut the TOY43 blade, seated a fresh CR2016, and handed it over. He turned the key, the security light on the dash flickered once and went out, and the V6 fired right up in the same lot where he lost the original.

Whole job, lock decode to engine running, took about 50 minutes. The dealer quoted him a tow plus a multi-day wait. He drove home instead.

Toyota 4runner Mobile Service FAQ

Real costs, no dealer surprises

I lost my only key for a 2011 Toyota 4Runner. Can you make one without the original?
Yep. All-keys-lost on the fifth-gen 4Runner is a standard field job for me. I decode the TOY43 lock cylinder to get the bitting, cut a new blade, then connect through the OBD-II port to reset the immobilizer ECU (board 89784-35150) and register a fresh 4D-67 transponder chip. The old missing key gets erased so it can no longer start the engine. Takes about 45 to 55 minutes depending on the lock condition. No tow needed, done right at your car.
Is a mobile locksmith cheaper than going to the Toyota dealer for a 4Runner key?
Does your price include cutting and programming, or are those separate?
My 4Runner's security light stays on solid and the engine cranks but won't start. Is that the key?
Can I buy an HYQ12BBY remote head key online and program it myself?
