The 2000–2003 RX uses the same key setup, so everything on this page applies to those years too. The full picture is on the Lexus RX key guide.

2002 Lexus RX: key facts

Key type: Transponder chip key
Push-to-start: No
Transponder chip: 4C
Programming: OBD
All keys lost: We can originate new keys on site

RX300: 4C chip on a laser-cut TOY48 short blade with a separate remote fob. All-keys-lost on the earliest cars can require an immobilizer ECU reset rather than a quick OBD add — we confirm by year and VIN.

Same key system as the 2000–2003 RX

Lexus kept the RX's key system unchanged across 2000–2003, so everything about replacing a 2002 key — blanks, programming, and what happens if every key is lost — matches the rest of that run. The full year-by-year breakdown lives in our Lexus RX key guide.

What drives the price is the key type, whether you still have a working key, and where the car is parked. There's more on Lexus programming in general on our Lexus key page.
