- All keys lost: no existing working key needed.
- PIN / security code: required — NASTF + Lonsdor + dealer.
- Online / server access: not required (offline programming).

Notes & cautions
- This chassis Chevrolet City Express uses NXP PCF7937/7952 HITAG-2 (2014-2018). GM HITAG-2 era — Autel IM608 + IMKPA GM, AD Smart Pro ADS178 GM, Lonsdor K518 USA + GM adapter, Xhorse VVDI Key Tool Plus + KH100 GM. PIN via BCM or NASTF.
- GM smart proximity or remote head key: ensure existing key fob battery is functional before starting.
- Verify chip before booking (this chassis facelift): GM spans Passlock (pre-2008 econoline) → PK3/PK3+ (2000-2010 Cadillac/Chevy) → HITAG-2 (2010-2016) → HITAG-AES Global A (2017-2019) → Global B (2020+ NASTF VSP SAC required). Mid-cycle K2XX/T1XX facelifts swap chip — confirm transponder ID from a working key with Lonsdor K518 reader before quoting.
- Tool kit context: Autel IMKPA GM module is the dominant add-key accessory (~$5-15/session for Global B cloud). AD Smart Pro ADS178 also strong GM. Lonsdor LKE Smart Key Emulator for K518 simulated-key flow. Xhorse KH100 + GM module. APB112 simulator, G-Box bench EEPROM NOT typically needed. XP400 PRO only for BCM EEPROM bench fallback.
- All existing keys erased. Bring ALL replacement keys before starting — minimum 2.
- No manual AKL for Chevrolet City Express GM HITAG-2 — professional tool mandatory.
- AKL for GM HITAG-2 needs PIN (NASTF / BCM read / Tech 2 dealer) + Global B needs NASTF VSP SAC.
- Keep all existing/lost key fobs at least 10 metres from vehicle during AKL.
- AKL accessory needs: NASTF VSP SAC for Global B chassis (mandatory); Autel IMKPA + GM token, Lonsdor LKE Smart Key Emulator for K518 simulated-key AKL path, Xhorse KH100 GM. APB112 simulator NOT mandatory. G-Box bench EEPROM NOT used. XP400 PRO only if BCM EEPROM corrupted (rare).
