How to copy & use this key
1
Learn via dealer software (SDD)
The standard dealer route — learn the key through SDD / dealer software over OBD. When prompted, press a button on the HW12 to learn it as a spare key to the vehicle.
2
Key-to-key copy
Best when you already have a working key. Read the existing key on the Lock50 HW01 or HW04 and copy it straight onto the HW12 in seconds — no vehicle, no tokens.
3
Dump-to-key copy
When you have no working key: write from a KVM dump to the HW12 with the Lock50 HW01 or HW04. Defender KVM part refs: DH1215K600AB / DH1215K600BC (2-plug).
4
Bench copy with HW03-CB — no opening
Tools required
To write data to this key you need the Lock50 HW01 JLR Key Tool or the Lock50 HW04 OBD Tool. Bench copy without opening the module uses the HW03-CB KVM/RFA 2-in-1 test cable (with the HW03-D OBD cable). These keys work on the KVM: a new key is added over OBD when the KVM is unlocked, and copied over OBD when it is locked.

On the bench / key tool (no OBD)
| Function | What it does & when you need it |
|---|---|
| SW01 | Read this key — part, frequency, key position and locked status. Always identify the key first. |
| SW15 | Emulate from dump — Defender ALM module (LR084667 / DH12-15K600-AB / -BC) copy, spare or all-keys-lost, onto Lock50 HW11 / HW12 keys. |
| SW10 | Direct key-to-key copy of an unlocked key — done in seconds. |
| SW11 | Unlock a locked key without opening it, then relearn the key. |
Advice for clients
Identify the key first with SW01. On the classic Defender the key is copied from the ALM module dump using SW15 — works for a spare or when all keys are lost. If you already have a good unlocked key, a direct SW10 key-to-key copy is the fastest route, and a locked key can be recovered with SW11 without opening it. There is no OBD add-key route for these keys.
