The 2025–2026 NX uses the same key setup, so everything on this page applies to those years too. The full picture is on the Lexus NX key guide.

2026 Lexus NX: key facts

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

HYQ14FLD fob listings run through 2026, but we did not find the chip named for these years — same-generation hardware is expected and confirmed by VIN. All-keys-lost remains server-authenticated specialist or dealer work.

Same key system as the 2025–2026 NX

Lexus kept the NX's key system unchanged across 2025–2026, so everything about replacing a 2026 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 NX 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.
