🔧 PRO TIP
The 2004 Sequoia uses a separate remote (HYQ12BBX, part 89742-0C030) and a transponder key with a Texas Instruments 4C/4D chip, depending on production run. Most 04 Sequoias landed with the 4D-67 chip running Toyota's fixed-code immobilizer. The remote is just for locks, panic, and hatch. It does not start the car. If you turn the key and nothing happens, the problem is the transponder in the key blade, not the remote. Two different things, two different fixes.

2004 Toyota Sequoia Remote Replacement - Fast, Affordable & Professional

Got a call around 9pm from a guy in the Fillmore Towne Theatre neighborhood of Fillmore. His 2004 Sequoia was sitting in the driveway and he had zero working keys. The original spare went missing a year ago and then his daily key snapped off inside the ignition cylinder that afternoon. He got the broken piece out with needle-nose pliers, but now he had a key blade with no bow and a remote fob with no way to start the truck.

He had already called the dealer. They told him to tow it in and leave it, could be a couple days. He was not excited about that plan.

I pulled up, set my tools on the passenger seat, and got to work. The 04 Sequoia runs the 4D-67 transponder through the immobilizer ECU, board number 89780-0C050 on most first-gen models. I connected through the OBD-II port, read the existing key data, and registered a fresh 4D-67 transponder chip to the vehicle. Cut the new key on site using the key code pulled from the lock. Then I paired his HYQ12BBX remote back up so he had full lock, unlock, panic, and rear hatch function on all four buttons.

He sat on his porch the whole time, just watching. When the engine turned over on the first crank, he nodded once like he had been holding his breath. Whole thing was done in about 25 minutes, and he never left his own driveway.

Toyota Sequoia Mobile Service FAQ

Real costs, no dealer surprises

Why is replacing a key for my 2004 Toyota Sequoia so expensive at the dealer?
The 2004 Sequoia uses a transponder key with a 4D-67 chip tied to the immobilizer ECU. Dealers charge for the blank, the cut, and then a programming session that requires their Techstream diagnostic system. On top of that, most dealers add a diagnostic fee before they even touch the key. Sequoia owners on Toyota forums regularly report total dealer bills north of what makes sense for a single key. A mobile locksmith with the right programmer and key stock does the same registration through the same OBD-II port, on site, for way less.
What exactly is the remote on my 2004 Sequoia, and does it start the engine?
