Programming procedures
What the job needs
- Add a key: 1 existing working key required.
- All keys lost: no existing working key needed.
- PIN / security code: Toyota cloud seed-code.
- Online / server access: not required (offline programming).
- On-board (no tool) sequence: not available — Toyota RAV4 Prime H chip smart/remote key requires professional OBD tool — no self-programming procedure.
- On site: engine off · Maintain 12V+ · Clear IMMO DTCs.
- Bring: Photo ID + vehicle registration. VIN cross-check before start.
Tool coverage
Documented for this case on: Autel IM608 Pro II · Autel IM508S · Autel KM100 · Xhorse Key Tool Plus · Xhorse Key Tool Max Pro · Lonsdor K518 Pro / K519 · OBDSTAR X300 DP Plus · AutoProPad G2/G3 · Advanced Diagnostics Smart Pro · Launch X431 IMMO Elite / IMMO Plus. Step-by-step menu paths for each tool are in the app.
Notes & cautions
- This chassis Toyota RAV4 Prime uses Texas H 8A chip (DST-AES, 128-bit, integrated in proximity fob, 2021-2025). H-chip OBD covered by Lonsdor K518 USA + ADP adapter natively, and Autel IM608 Pro II via IMKPA token (~$5-15/session for seed-code calc). 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.
- Smart proximity key: ensure existing key fob battery is functional before starting.
- Post-2024 Autel US firmware: Toyota/Lexus add-key on Toyota RAV4 Prime 2021-2025 may be affected by TMNA restrictions — verify on current firmware before booking.
- Verify chip before booking: H-chip vs G-chip vs 4A AES generations share a fob shell but use different cryptosystems — confirm transponder ID from a working key with Lonsdor K518 reader before quoting.
- Tool kit context: most aftermarket flows use Autel IMKPA accessory or Lonsdor LKE Smart Key Emulator for cloud seed-code; Autel APB112 simulator and Autel G-Box bench EEPROM are NOT required for OBD-only add-key on this Toyota family. XP400 PRO only needed for damaged ECU EEPROM dump fallback.
- All existing keys erased. Bring ALL replacement keys before starting — minimum 2.
- No manual AKL for Toyota RAV4 Prime H chip smart key — professional tool mandatory.
- AKL for Toyota/Lexus H chip typically needs dealer-issued PIN or seed-code cloud calc — confirm OBD AKL path before quoting.
- Keep all existing/lost key fobs at least 10 metres from vehicle during AKL.
- Post-2024 Autel US firmware: Toyota/Lexus AKL on Toyota RAV4 Prime 2021-2025 reportedly restricted per TMNA — verify capability before booking.
- AKL accessory needs: Autel IMKPA Toyota module for cloud seed-code calc, Lonsdor LKE Smart Key Emulator for K518 simulated-key AKL path. APB112 simulator and Autel G-Box bench EEPROM are NOT mandatory for standard AKL on this Toyota family — only XP400 PRO is needed if the ECU EEPROM is corrupted (rare).
Lockout
Door pick / decode: Lishi TOY43AT (CW).
