The 2013–2017 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.

2016 Lexus LS: key facts

Key type: Smart / proximity key
Push-to-start: Yes
Transponder chip: Varies by trim — we confirm by VIN
Programming: OBD
All keys lost: We can originate new keys on site

LS460/LS600h: HYQ14ACX fob with trunk button (GNE board 271451-5290). Catalog listings disagree on the chip inside this fob — most describe it as 'DST+'/DST80, but at least one lists DST40 — so we match replacements by the fob's FCC ID and board number, not the chip label. All-keys-lost via OBD smart-code reset with professional tools.

Same key system as the 2013–2017 LS

Lexus kept the LS's key system unchanged across 2013–2017, so everything about replacing a 2016 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.
