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: NATS PIN tool-side via OBD.
- Online / server access: not required (offline programming).
- On-board (no tool) sequence: not available — Nissan Altima NATS-5/6 requires professional OBD tool — no self-programming procedure for ID46 transponder.
- On site: engine off · Maintain 12V+ · Clear NATS 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 Nissan Altima uses Texas PCF7936 (ID46) with NATS-5 / NATS-6 immobilizer (2007-2012). NATS-5/6 covered natively by Lonsdor K518 USA, Autel IM608 Pro II + IMKPA Nissan module, Xhorse VVDI Key Tool Plus Nissan module, OBDSTAR X300 DP Plus Nissan menu. PIN read tool-side via OBD — NASTF lookup not required for NATS-5/6 era.
- Standard 16-pin DLC OBD path; no XP400 PRO bench, no APB112 simulator needed for add-key.
- Smart proximity or remote head key: ensure existing key fob battery is functional before starting.
- Verify chassis NATS generation before booking: NATS-5 (1999-2009 typical) and NATS-6 (2010+ typical) differ in tool flow — confirm transponder ID from a working key with Lonsdor K518 reader before quoting. Some 2010+ Nissans transitioned to HITAG-AES in mid-cycle — verify chip before ordering blanks for facelift years.
- Tool kit context: Autel IMKPA Nissan module is the dominant add-key accessory ($5-10/session). Lonsdor K518 USA + Nissan adapter and Xhorse VVDI Key Tool Plus + Nissan KH100 module also confirmed. APB112 simulator, G-Box bench EEPROM, XP400 PRO, LKE Smart Key Emulator NOT required for OBD-only NATS add-key.
- All existing keys erased. Bring ALL replacement keys before starting — minimum 2.
- No manual AKL for Nissan Altima NATS-5/6 — professional tool mandatory (Lonsdor K518 / Autel / Xhorse / OBDSTAR).
- NATS-5/6 AKL via OBD — PIN read tool-side; NASTF not required. Newest NATS-6 chassis (2010+) may dealer-bind on some VINs.
- Keep all existing/lost key fobs at least 10 metres from vehicle during AKL.
- AKL accessory needs: Autel IMKPA Nissan token for cloud calc on newer NATS-6 VINs, Lonsdor LKE Smart Key Emulator for K518 simulated-key path. APB112 simulator and G-Box bench EEPROM NOT mandatory. XP400 PRO only needed if BCM/NATS EEPROM is corrupted (rare).
