1998 Lexus LX Transponder Key Replacement - Fast, Affordable & Professional
Got a call around 7pm on a Saturday from someone near Cottage Hospital in Santa Barbara. Their 1998 Lexus LX 470 turned over but would not fire. Dash security light was doing the fast-blink-then-solid thing, which told me before I even showed up that the immobilizer was rejecting the transponder.
They had one key. The blade was worn thin and the plastic head had a hairline crack running right through where the 4C chip sits. That chip had shifted just enough inside the housing that the transponder coil around the ignition cylinder could not get a clean read.
I pulled out a fresh TOY48 blank with a new 4C glass chip, cut it to code on the van, and then cloned the original transponder data using my VVDI Key Tool. The 1998 LX 470 does not need on-board programming for 4C chips the way newer systems do. You clone the existing chip value onto the new one, and the transponder ECU accepts it like nothing changed.
Key went in, security light did its normal brief flash and went out, engine caught on the first crank. The owner just sat there for a second with his hand still on the key, like he was waiting for it to stall.
I made him a second spare while I was there. Two keys in labeled drawers, ten minutes of extra work, and he went from one cracked key away from a tow to having a backup set.

“I needed two keys made for my Honda Element. Friendly, fast, fair pricing, and far better than any other locksmith I have used in the area. Best service by far.”
“I lost my Honda Passport key and called EZ Car Keyz. He came out and made a new key in under five minutes. Legendary service.”
“They responded instantly, showed up within an hour, and arrived exactly when they said they would. Made a copy and programmed a fob for my 2014 car with a worn ignition in about 15 minutes. The new key works perfectly and feels like a dealer key.”
