Notes & cautions
- This chassis Lexus 4D67 dot chip + G-chip smart key. IS XE20 (2006-2013) — 4D67 + late G-chip on 2010+ 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.
- 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 IS XE20 4D67 — professional tool mandatory.
- OBD AKL typically needs dealer-issued PIN (Toyota Techstream + NASTF) or EEPROM dump on some IS XE20 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.
