🔧 PRO TIP
The 2003 Land Cruiser (J100 series) runs Toyota's Texas Instruments 4C/4D transponder system, specifically a 4D-67 chip in the remote head key. But here is the catch: if your VIN starts with "J" (Japanese-built), the immobilizer config can differ from a US-built unit. I always pull the VIN first because loading the wrong seed calculation bricks the registration process on the Autel. The 89070-48821 key uses a CR2016 battery. Weak cells kill remote range long before the transponder side shows any trouble.

2003 Toyota Land Cruiser Remote Head Key Replacement - Fast, Affordable & Professional

Got a call around 8pm from a woman in the Blanchard Community area of Santa Paula. She was at the hospital parking lot. Her kid had just been discharged and she needed to get home. Her 2003 Toyota Land Cruiser would not respond to the key at all. Dead remote buttons, and even holding the key near the steering column was not getting a read from the immobilizer.

She had already tried the dealer. Closed for the night.

I got out there and opened the door manually. Once I had my IM608 II on the OBD-II port, I pulled up the immobilizer module and read the system. Her HYQ12BBT remote head key had a corroded CR2016 contact inside, and the corrosion had gotten bad enough that it was affecting the board near the transponder coil area too. The 4D-67 chip was not registering cleanly.

Replaced the full key. Cut the blade to match, registered the new 4D-67 transponder through the IM608, programmed the remote side, and walked every button. Lock, unlock, panic. Then engine start, three cycles. Solid.

From her phone call to engine running was about 45 minutes. She put her kid in the car seat, pulled the medicine bag off her shoulder, and just sat in the driver's seat for a second before she turned the key. Did not say anything. Did not need to.

That is the whole job sometimes. Just get someone home.

Toyota Land Cruiser Mobile Service FAQ

Real costs, no dealer surprises

Are you licensed and insured to work on Toyota vehicles in California?
Yes. EZ Car Keyz is licensed through the California Bureau of Security and Investigative Services (BSIS License LCO 6792) and carries full insurance. We also hold NASTF Vehicle Security Professional certification, which gives us authorized access to Toyota's security codes and PIN retrieval through the same credentialing pipeline dealerships use. Without NASTF access, a locksmith cannot pull the immobilizer data needed to register a new 4D-67 transponder on a 2003 Land Cruiser. Not every mobile locksmith carries this credential. If they cannot tell you their NASTF status, that is worth asking about.
How do I know a mobile locksmith is not going to scam me?
Will the replacement key work exactly like my original Toyota key?
My 2003 Land Cruiser key turns but the engine cranks and will not start. Is that the immobilizer?
Can I program a new key for my 2003 Land Cruiser myself with the two-key add method?
