🔧 PRO TIP
The 2000 RX 300 uses a remote head key with FCC ID NI4TMTX-1 and a Texas Instruments 4C transponder chip, not a smart proximity system. That means the key turns in the ignition like any traditional setup, but the immobilizer still talks to the chip in the key head. If the red SECURITY light on the dash stays solid after you turn the key, the transponder is not being read. Check for a cracked key shell before assuming the worst. Battery is a CR1616 for the remote buttons.

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

Got a text from a guy in Peninsula Park, Oxnard. His 2000 RX 300 was sitting in his driveway and his only key had snapped right at the blade, clean break where the metal meets the plastic head. The transponder half was in his hand, the blade was still jammed in the ignition barrel.

He had already called the Lexus dealer. They told him the key had to be ordered by part number 89070-48020, it would take about a week, and he would need to tow the car in for programming. He did not love that answer.

I pulled up, extracted the broken blade from the cylinder with a standard extractor, and decoded the wafers right there in his driveway. Cut a fresh TOY43 blade on my mobile machine. The key head I used has the same NI4TMTX-1 housing with a 4C chip inside, so I matched the transponder to the immobilizer ECU using my diagnostic tool connected at the OBD-II port under the dash.

The part that made him laugh: his dog sat in the passenger seat the whole time watching me through the windshield like I was performing surgery. Never barked, never moved. Just stared.

Key turned, engine fired, remote locked and unlocked all doors. He went from dead in the driveway to driving in about 40 minutes, for a fraction of what the dealer quoted him.

“Locked out on a weekend night and everyone else wanted $300+. EZ Car Keyz sent Roman late at night for much less. He worked for over an hour and did not give up until the door opened. They even made a new key on the spot.”

Lexus RX Mobile Service FAQ

Real costs, no dealer surprises

How long does it take to replace a key for a 2000 Lexus RX 300?
Depends on whether you have a working key or not. If you still have one, adding a spare is quick. I clone the 4C transponder chip, cut the TOY43 blade, and test it. About 20 minutes total. If all keys are lost, the immobilizer ECU on the RX 300 has a timed security lockout period of roughly 16 minutes before it accepts a new transponder registration. So all-keys-lost jobs run closer to 30 to 45 minutes from the time I pull up. Either way, same visit, same day, done on site wherever the car is parked.
How fast can you get to my location in Oxnard?
Can I get a 2000 Lexus RX key made the same day I call?
My 2000 RX 300 SECURITY light stays on and the engine cranks but won't start. Is the key bad?
Can I program a new key for my 2000 RX 300 myself?
