🔧 PRO TIP
The 2004 SC 430 runs a Texas Instruments 4D-67 transponder chip inside the HYQ12BBK remote head key. That chip talks to the immobilizer ECU (part number 89780-24030) through the transponder amplifier coil around the ignition cylinder. If the red security light on the dash blinks and the engine cranks but won't fire, the chip isn't being read. Before you panic, pull the key out, check for cracks near the blade base where the chip sits, and try reinserting slowly. A loose or cracked shell can shift the chip just enough to kill the read distance.

2004 Lexus SC Remote Head Key Replacement - Fast, Affordable & Professional

Got a call around 10pm from a guy stuck in an underground parking garage in the Mesa neighborhood of Santa Barbara. His only key for a 2004 SC 430 was gone. Checked pockets, retraced to the elevator, walked the stairwell twice. Nothing.

He was ready to call a tow truck just to move the car somewhere safe overnight. Didn't know his VIN off the top of his head, didn't have his registration on him.

I kept him on the phone. Told him to look at the base of the windshield, driver's side. He read me the VIN. Then I had him check his insurance app and he pulled up registration there. With those 17 digits I already knew I needed the HYQ12BBK with the 4D-67 chip, TOY48 blade, and the three-button layout. I prepped everything before I left.

Under the garage lights I cut the blade to his lock, generated the transponder profile on my VVDI Key Tool, and registered it to his immobilizer ECU through the OBD-II port. Programmed the remote functions, tested lock, unlock, and trunk on all doors. The whole thing took maybe 35 minutes.

He got quiet for a second when the engine turned over. Then he just said, "I thought I was sleeping in the stairwell tonight."

He drove home. The dealer was closed anyway, and even if they weren't, this would have meant a tow plus a wait. The VIN tells me everything before I show up. Text it ahead of time if you can.

“The dealership quoted me $600 for a new Honda key. EZ Car Keyz did it for $225, same day, cut and programmed at my house. Works perfectly. Everyone should know this is an option.”

“A+ service at an even better price. Tim was a lifesaver. I lost my original and only key for my Audi and he was willing to come to my location at 8pm the same day. He worked fast, communicated clearly, and made sure everything worked before leaving.”

Lexus SC Mobile Service FAQ

Real costs, no dealer surprises

I lost my only key for a 2004 Lexus SC 430. Can you make one from nothing?
Yep. All-keys-lost on the SC 430 is a standard job for me. I read the immobilizer ECU data through the OBD-II port, generate a new 4D-67 transponder chip, cut a fresh TOY48 blade to your locks, and program the HYQ12BBK remote. The old missing key gets erased from the system so it can't start the car. The whole process runs about 30 to 45 minutes on site. No tow needed, no waiting on a dealer parts counter.
Is a mobile locksmith cheaper than going through the Lexus dealer for this key?
Does your price cover everything, or are cutting and programming extra?
My 2004 SC 430 cranks but won't start and the security light is blinking. Is the key bad?
Can I program a new key myself or use an online add-key procedure on the 2004 SC 430?
