🔧 PRO TIP
The 2000 Lexus SC runs Toyota's first-gen immobilizer, same as the Soarer in Japan. Under the shell, the transponder is a Texas Instruments 4C glass chip, not the later 4D electronic type. FCC ID HYQ1512V covers the remote head key with three buttons on part number 89070-33470. The remote and the immobilizer are two separate systems here. The remote does lock, unlock, and panic over RF. The immobilizer reads the 4C chip through the coil around the ignition cylinder. If the red security light on the dash stays solid after you turn the key, the chip is not being read. Check the key blade for cracks near the head first, because a hairline fracture there can shift the chip just enough to kill the read.

2000 Lexus SC Remote Head Key Replacement - Fast, Affordable & Professional

Got a call from a guy out near Hummingbird Trailhead in Simi Valley. He had a 2000 Lexus SC 400, the V8 coupe, and his only key had stopped turning over the engine. Doors unlocked fine with the remote, dash lights came on, but crank? Nothing. Just the red security indicator sitting there solid on the instrument cluster.

He told me he had already called another locksmith off a cheap ad. That guy showed up, said the whole ignition cylinder needed replacing, quoted him a big number, and left when the owner wanted a second opinion. Good instinct.

I drove out and checked the basics first. Key turned in the cylinder with normal resistance, so the wafers were fine. Battery terminals were clean. The security light was the tell. Solid red, not flashing. That means the immobilizer ECU on the 2000 SC, board number 89780-24020, was not seeing the 4C transponder chip in his key at all.

I pulled the key apart on my work mat. The 4C glass chip had shifted inside the key head. Tiny movement, but enough to put it out of range of the coil antenna around the cylinder. Reseated the chip, tested the read with my T-Pro, got a clean response.

Key went back in. Cranked first try. The guy just stood there for a second, then asked if that was really it.

He did not need a new ignition cylinder. He did not need a tow to the Lexus dealer. He needed someone who checked the simple thing first.

Lexus SC Mobile Service FAQ

Real costs, no dealer surprises

I lost all my keys for my 2000 Lexus SC. Can you still make a new one?
Yep. All-keys-lost on the 2000 SC is a standard job. This generation uses Toyota's first-gen immobilizer with a 4C transponder chip, so the security reset goes through the immobilizer ECU, part number 89780-24020. I read the ECU, register a new key with a fresh 4C chip, and cut the blade to your door lock. The old missing keys get wiped from the system so they cannot start the car. The whole thing runs about 30 to 45 minutes on site. No tow, no dealer appointment, no waiting on parts to be ordered.
Do I have to tow my 2000 SC to the Lexus dealer if I have no working key?
How long does a full key replacement take on a 2000 Lexus SC?
My 2000 SC remote works for locks but the engine will not crank. Is the key bad?
Can I buy an HYQ1512V remote head key online and program it myself?
