The 2018–2026 LS uses the same key setup, so everything on this page applies to those years too. The full picture is on the Lexus LS key guide.

2020 Lexus LS: key facts

Key type: Smart / proximity key
Push-to-start: Yes
Transponder chip: 8A (128-bit DST-AES)

HYQ14FBF smart fob; a HYQ14FBZ (board 3410) variant also appears from 2020. From 2020, US all-keys-lost generally requires Toyota/Lexus server codes with locksmith-credentialed (NASTF VSP) access or tool-specific authorization; add-a-key with a working fob is less restricted.

Same key system as the 2018–2026 LS

Lexus kept the LS's key system unchanged across 2018–2026, so everything about replacing a 2020 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 LS 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.
