Lock50 software functions for this key
These are the Lock50 software functions that work with this NCF29A4V PSFOB (non-UWB) change-ID key at 433 MHz. Each one runs on the HW04 tool — click any function to open its own page in a new tab. Reading the key on the tool also shows how many of the 10 rewrites are left.
Copy a key from an RFA module dump (bench, no OBD) — RFA module only, never the KVM
| Function | What it does & when you need it |
|---|---|
| SW04 | Load the JPLA-19H440 RFA module MCU (SPC560B60L3) DFLASH dump you read — copy a key. Remote + emergency start only unless UWB is turned on via OBD in the BCM. |
| SW05 | Load the K8D2-19H440 RFA module MCU (SPC560B60L3) DFLASH dump — copy a key. Remote + emergency start only unless UWB is turned on via OBD in the BCM. |
| SW07 | Load the M9R3-19H440 RFA module MCU (SPC560B60L3) DFLASH dump — copy a key. Remote + emergency start only unless UWB is turned on via OBD in the BCM. |
| SW06 | Load the Jaguar J9C3-19H440 RFA module MCU (SPC560B60L3) DFLASH dump — copy a key. Remote + emergency start only unless UWB is turned on via OBD in the BCM. |
| SW08 | Work from the BCM ST95128 EEPROM dump — copy a key (JPLA / L8B2 / M8E2 / R8E2). |
On the bench / key tool (files, dumps & key-to-key — no OBD)
| Function | What it does & when you need it |
|---|---|
| SW01 | Read the key first — part, frequency, key position, locked status and how many of the 10 rewrites are left. Always identify the key before any copy. |
| SW13 | Add this key to an unlocked RFA MCU dump — NCF29A4V PSFOB non-UWB, RF and keyless supported. New files are written back to the RFA. |
| SW10 | Direct key-to-key copy of an unlocked key — for a damaged key, done in seconds, no OBD. |
Over OBD (in the vehicle)
In-vehicle route for this key: use the HW03-C tool with the M1 adapter in the car, or the HW03-CB bench adapter for 2017–2020 vehicles.
| Function | What it does & when you need it |
|---|---|
| SW30 | EVA2 — add OEM UWB / PEPS keys when the RFA and BCM are locked (2021–2025+). On this key: if you do not have Service Mode, use SW36 first, then SW30 once you have 2 keys. L8B2 / R8E2 / M8E2 supported. |
| SW35 | NCF29A4V key duplicator over OBD when the RFA is locked (2017–2020). |
| SW36 | Key duplicator on a locked RFA (2017–2025) in the vehicle using the HW03-C adapter — the route named on this key. |
| SW33 | Alarm / arm OFF over OBD using the HW03-C RFA adapter (2017–2020) when the car is in alarm state. |
Advice for clients
- Read the key first with SW01 to confirm the part, frequency and how many of the 10 rewrites are left.
- Copy a key from an RFA module dump (bench, no OBD): read the RFA module MCU DFLASH and use SW04 (JPLA-19H440), SW05 (K8D2-19H440), SW07 (M9R3-19H440) or SW06 (Jaguar J9C3-19H440). RFA module only, never the KVM.
- Copy a key from the BCM ST95128 EEPROM dump (JPLA / L8B2 / M8E2 / R8E2) with SW08.
- A copied key gives remote and emergency start only unless UWB / passive entry is turned on over OBD in the BCM.
- File or key-to-key copy on the bench: SW13 and SW10.
- In the vehicle with the RFA and BCM locked: add OEM UWB / PEPS keys on EVA2 with SW30; if the car has no Service Mode, use SW36 first to get two keys, then run SW30.
- When only the RFA is locked: duplicate this key in the car with SW35 over OBD, or SW36 using the HW03-C tool with the M1 adapter (or the HW03-CB bench adapter, 2017–2020); use SW33 to take the alarm / arm state off first if the car is armed.
- All of these run on the HW04 tool.
We show you that Lock50 Products allow you make even spare or lost non original full working keys in the Vehicles even when in Alarm state.
The Impossible does not end thier and as then Lock50 will add OEM keys in the locked RFA and BCM.
When you read the key it will show how many rewrites left.
