Notes & cautions
- This chassis Mazda Protege5 uses Texas 4D63 80-bit transponder (2002-2003). 4D63 covered by Autel IM608 Pro II + IMKPA Mazda module, Lonsdor K518 USA + Mazda adapter, Xhorse VVDI Key Tool Plus + KH100 Mazda, OBDSTAR X300 DP Plus Mazda menu, AutoProPad G2/G3 Mazda. Manual pedal-dance flow available with master key.
- Standard 16-pin DLC OBD path; no XP400 PRO bench, no APB112 simulator needed for add-key.
- Key fob/blade: ensure existing battery is functional before starting.
- Verify chassis chip before booking: 4D63 (2003-2013 era) gives way to ID49 HITAG-PRO (2014+) on facelift/redesign Mazda3/CX-5/Mazda6 mid-cycle. Some 2013 MY units shipped with mixed chip — verify transponder ID from a working key with Lonsdor K518 reader before quoting.
- Tool kit context: Autel IMKPA Mazda module is the dominant add-key accessory ($5-10/session). Lonsdor LKE Smart Key Emulator for K518 simulated-key flow on master-less chassis. Xhorse KH100 + Mazda module also confirmed. APB112 simulator, G-Box bench EEPROM NOT required for OBD-only 4D63 add-key. XP400 PRO only for IMMO box bench fallback.
- All existing keys erased. Bring ALL replacement keys before starting — minimum 2.
- No manual AKL for Mazda Protege5 4D63 — manual pedal-dance requires master key, AKL by definition has no master. Professional tool mandatory.
- 4D63 AKL via OBD — PIN read tool-side; NASTF lookup usually not required.
- Keep all existing/lost key fobs at least 10 metres from vehicle during AKL.
- AKL accessory needs: Autel IMKPA Mazda token, Lonsdor LKE Smart Key Emulator for K518 AKL path, Xhorse KH100 Mazda. APB112 simulator NOT mandatory. G-Box bench EEPROM NOT used. XP400 PRO only if IMMO box EEPROM corrupted (rare; usually accessible over OBD).
