🔧 PRO TIP
The 1999 GS remote head key (HYQ1512V) uses a Texas Instruments 4C transponder chip, not 4D. That matters because 4C is a fixed-code chip with no rolling encryption, which means cloning is possible if you have a working key to read from. But if you lose all keys, the immobilizer ECU needs a full reset through the OBD-II port to accept new 4C transponder data. A dead CR1616 kills the remote buttons but the transponder still starts the car, since 4C is passive and powered by the antenna coil around the ignition.

1999 Lexus GS Remote head key Replacement - Fast, Affordable & Professional

A woman near Miramar Beach in Montecito called after her clutch purse was stolen off the back of her chair at a wine bar. Keys, ID, cards, all gone. She borrowed someone's phone and called the police, then her husband, then me.

Her 1999 Lexus GS was sitting in the lot with zero keys. The husband had already called the Lexus dealer. They wanted the car towed in, said it would be four to five business days, and recommended a full immobilizer reprogram. The quote made him go quiet on the phone.

I got there that evening. All-keys-lost after a theft is a specific job. The stolen key still has a valid 4C transponder code in it, so the first step is wiping the immobilizer ECU's key memory so that fob is electronically dead to the car. I used my IM608 to access the immobilizer module, cleared the old key data, and registered two fresh HYQ1512V remote head keys from scratch. Decoded the lock cylinder, cut both emergency blades on site, and programmed the 4C chips one at a time through the OBD-II port.

Both fobs were locking, unlocking, and starting the car before the police even called back with a case number.

She drove home that night. The stolen key can't start anything now. That's the part that mattered most to her, and it was done in under an hour in a parking lot, not five days at a service bay.

Common Lexus GS Pricing Questions

What it costs and what you get

Why is a 1999 Lexus GS key replacement so expensive at the dealer?
The key itself (part number 89070-33470) has a transponder chip inside that has to be registered to your car's immobilizer ECU. Dealers charge for the blank, the cutting, and a separate programming fee on top. If you need towing because you have no working key, that's another line item. And if it's all-keys-lost, the labor goes up because the immobilizer memory needs a full wipe before new keys can be written. With us, the whole thing happens on site in one visit for a fraction of what they quoted. No tow, no waiting days for a parts order.
What exactly is a remote head key on the 1999 Lexus GS?
How does a mobile locksmith compare to the dealer for this key?
My key turns in the ignition but the engine cranks and won't start. Is it the immobilizer?
Can I buy a HYQ1512V blank online and program it myself?
