| Car state | How to add this key | Where |
|---|---|---|
| UWB off + RFA unlocked | Learn this key directly over OBD with HW04 — any package A+ to C+. | OBD |
| UWB on + RFA unlocked | Turn UWB off with 1 Click on HW04, then learn this key over OBD — A+ to C+. | OBD |
| RFA locked, EVA2 2021+ | With 2 working keys, or the car in service mode, or after unlocking the RFA with SW40: UWB off with 1 Click if the car has it on, then learn this key (key number 3 with 2 keys / service mode — same function as the original keys) — A+ to C+. After an SW40 unlock you can also erase the old keys and program new keys into the RFA and BCM to replace them all, with no parts swapped. If the RFA cannot be unlocked: fit a new RFA and adapt it (package B or C) — works even with a locked BCM, 2017–2026. | OBD |
| RFA locked, 2017–2020 (non-EVA2) | This fixed-ID key cannot be added to a locked RFA. To fit this key: replace the RFA with a new unlocked one, program it as new over OBD with HW04 (SW27 unlocked BCM / SW28 locked BCM, SW38 if the software is too high), then add this key to the new RFA (package B or C; works even with a locked BCM). UWB off with 1 Click over OBD first if the car had UWB — the key then has full function. Alternative without changing the RFA: copy the customer’s existing key onto a HW13 (433) / HW14 (315) change-ID key — over OBD or HW03-C / HW03-CB adapter when UWB is already off, SW36 with the HW03-C adapter (package C or C+) when UWB is enabled. | Replace RFA |
| RFA dump on the bench (HW04) | With the HW04 tool (SW01–SW15 functions; HW01 also runs them). RFA unlocked: read the RFA SPC560B MCU DFLASH dump, add this key with SW13 (new key) or SW14 (used / locked key) and write it back. RFA locked: unlock the dump first, then add this key. Remote and start work — no emergency start this way. | Bench |
| Copy an existing key onto this key | Not possible — this is a fixed-ID key, nothing can be copied onto it (no SW35, SW36 or key-to-key). For copy / duplicate jobs use the HW13 (433) or HW14 (315) change-ID keys. | Not possible |

Identify first (bench / key tool, no OBD)
| Function | What it does & when you need it |
|---|---|
| SW02 | Read this NCF29A4V key first — part, frequency, key position, locked / unlocked and PEPS / UWB status. Always identify the key before programming. |
Over OBD (in the vehicle) — add this key
| Function | What it does & when you need it |
|---|---|
| SW29 | Add or remove keys when the RFA and BCM are unlocked (2017–2024+) — the standard route to learn this fixed-ID key. |
| SW30 | EVA2 2021–2025+ — add keys when the RFA and BCM are locked, with 2 working keys or the car in service mode. |
| SW40 | Unlock the EVA2 RFA (L8B2 / M8E2 / R8E2, 2021+) over OBD when you have no service mode — then UWB off with 1 Click if the car has it on, and learn this key. Unlocked RFA also lets you erase the old keys and program new keys into the RFA and BCM — no parts swapped. |
Over OBD — UWB / PEPS off in the BCM (1 Click)
| Function | What it does & when you need it |
|---|---|
| SW25 | CCF UWB / PEPS ON or OFF 1 Click (2017–2024+) — unlocked BCM, unlocked RFA. Needed only if the car currently has UWB enabled. |
Over OBD — replace the RFA and add keys
| Function | What it does & when you need it |
|---|---|
| SW27 | New RFA programming when the BCM is unlocked (2017–2024+) — program the new RFA, then learn this key. |
| SW28 | New RFA replacement programming to 24+ when the BCM is locked (L8B2 / R8E2 / M8E2) — program the new RFA, then learn this key. |
| SW38 | Downgrade the RFA module software over OBD when it is too high (HW04-B or C) — before RFA programming or key adding. |
RFA dump route (bench — HW04 tool, SW01–SW15) — add this key to the dump
| Function | What it does & when you need it |
|---|---|
| SW13 | Add this new NCF29A4V PSFOB key to the RFA SPC560B MCU DFLASH dump (RFA unlocked, or unlocked first if it was locked) and write the files back. Works, but no emergency start on a key added this way. |
| SW14 | Add a used / locked NCF29A PSFOB (non-UWB) key to the RFA SPC560B MCU dump the same way. No emergency start on a key added this way. |
