Notes & cautions
- This chassis Lexus 4D67 dot chip + G-chip smart key. LS USF40 (2007-2017) — 4D67 + G-chip 4D60 on smart-key trims. Newer-era H-chip/8A on Autel needs IMKPA token (~$5-15/session). Lonsdor K518 USA + Honda/Toyota AES module covers G/H/8A natively. Xhorse VVDI Key Tool Plus needs 2024+ firmware for H-chip. Standard 16-pin DLC OBD path; no XP400 PRO bench, no APB112 simulator needed for OBD enrolment.
- This model spans 2007–2017 with two distinct FCC IDs (HYQ14AAB for 2007-2008, HYQ14ACX for 2009-2017) — confirm correct key blank for the specific year.
- Post-2024 Autel US firmware: Toyota/Lexus add-key may be affected by TMNA restrictions — verify on current firmware.
- All existing keys erased. Bring ALL replacement keys before starting — minimum 2.
- No manual AKL for Lexus LS USF40 4D67 — professional tool mandatory.
- OBD AKL typically needs dealer-issued PIN (Toyota Techstream + NASTF) or EEPROM dump on some LS USF40 ECUs — confirm OBD AKL path before quoting.
- Post-2024 Autel US firmware: Toyota/Lexus AKL reportedly restricted per TMNA — verify AKL capability on current firmware before booking.
