• 1 Key vs. 2 Keys Licences: A 1-key licence covers duplicating a single key. A 2-key licence programmes two keys in the same session at a discounted package price (e.g. PAYG SW34 is £200 for 1 key or £300 for 2 keys — saving £100).
• Unlocked Modules: Standard OBD key adding is 100% FREE (£0) across all tiers — no tokens needed.
• Locked Modules: For KVM, duplicate via OBD or direct cable (SW34). For locked UWB RFA, duplicate via HW03-C direct connection cable (SW36) into Lock50 Change-ID keys — direct connection is required to enable UWB keyless door functions. (2017–2020 non-UWB OBD copy uses SW35 on HW04-A, A+, B, C, and C+).
• Dump File Operations: Key adding or slot copying directly in module dump files is 100% FREE (£0) on HW04-A, B, C, and C+ (HW04 PAYG tool is locked and uses SW34/SW36 tokens only).

Supported Vehicle Modules & Key Transponder Hardware
Visual Identification & Direct Store LinksLock50 HW04 operates across both generations of JLR keyless immobilisers. Review the modules below to identify your vehicle system and select the correct transponder keys:
KVM Keyless Module
2010–2021 • DPLA, FK72, HPLA
Earlier generation keyless module. Unlocked units = FREE OBD add. Locked dealer units = SW34 duplicate into Change-ID keys without module replacement.
KVM Programming & Parts →
RFA PEPS & UWB Module
2017–2026+ • JPLA, K8D2, J9C3, M9R3
Modern PEPS & UWB module. Locked UWB units MUST be duplicated via SW36 & HW03-C direct connection into Change-ID keys to ensure keyless door functions work, or adapt replacement virgin RFA.
RFA Modules & Cables →
Lock50 Change-ID Keys
For Locked KVM & Locked RFA
Required for SW34 & SW36: HW13 / HW14 for 2017+ RFA; HW05-A / HW06-B for 2010–2021 KVM. Accepts cloned cryptographic transponder ID.
Browse Change-ID Keys →
Cheaper Fixed-ID Keys
For Unlocked OBD & Dump Adding
Standard Fixed-ID transponders (Lock50 HW17 / HW18 or OEM HW15–HW28). Used when adding new key positions into unlocked modules or bench dumps (100% FREE).
View HW17 Fixed-ID Fob →
Hardware Summary: When duplicating locked modules (SW34 for KVM, SW36 via HW03-C direct cable for UWB RFA), use Lock50 Change-ID keys (HW05/06 for KVM, HW13/14 for RFA). When adding keys to unlocked cars or bench dumps, save money by using cheaper Fixed-ID keys (HW17/18 or OEM).
Who Version B is for
For techs handling locked keyless modules. Replace the RFA outright, or swap/adapt one in — free, no per-job cost — instead of paying to copy each key. Key copying stays optional. Once a new RFA is adapted with SW28 you can use any keys, OEM or non-OEM — no need to copy keys from the RFA or KVM. Copying is only needed when the RFA or KVM is locked, and then only Lock50 Change-ID keys are allowed.
Built into Version B — no per-job token for the module work. Alarm OFF via OBD & CAN wires, replace the RFA on a locked keyless module (SW28) or program a new RFA on an unlocked BCM (SW27), then program any key, OEM or non-OEM — swap the RFA alone, no BCM change, no Service Mode. No need to copy keys from the RFA or KVM. Program a new / spare key: SW36 £400.
Replacing the RFA also erases every old key. When you replace the RFA (SW28 locked BCM · SW27 unlocked BCM) all previously programmed keys are erased from the BCM as well as the RFA — only the keys you program in afterwards will start the car. On an unlocked RFA & BCM you can also add or remove single keys over OBD (SW29).
Why deleting old keys matters: a lost, stolen or unreturned key keeps its ID in the immobiliser and can still start the car until it is erased; used cars often carry keys from previous owners that nobody can account for; after a loss, an insurer can treat keys that were never erased as negligence; and once erased you know exactly how many keys are live.
Why deleting old keys matters: a lost, stolen or unreturned key keeps its ID in the immobiliser and can still start the car until it is erased; used cars often carry keys from previous owners that nobody can account for; after a loss, an insurer can treat keys that were never erased as negligence; and once erased you know exactly how many keys are live.
Virgin RFA Module Route: In addition to swapping a new complete RFA, technicians can virginise or replace the processor on the client's existing RFA using standard programmer tools with the HW03-A adapter. Once initialised, update the module to the latest software in Lock50 and adapt it directly over OBD.
Which connection a job needs. On the older KVM system (roughly 2010–2018+ PCF7953), early or rare un-updated KVMs that are unlocked can be done directly over OBD only. However, 2013/2015+ KVMs with FK72 or HPLA part numbers are almost always LOCKED by JLR security updates: on these locked KVMs, standard OBD key-adding is blocked, but you do not need to remove or swap the KVM — simply use the SW34 Key Duplicator with a £100 token and Lock50 HW05/HW06 Change-ID keys to copy the key directly. On the newer RFA system the key is still read and programmed over OBD, but where the RFA is locked and UWB is enabled you also make a quick connection to the RFA to authorise the immobiliser first — still no soldering and no removing parts. On Version B: replace the RFA on a locked keyless module (SW28, built in, no token), or add OEM UWB/PEPS keys on a locked EVA2 system (SW30 — see the SW30 note below). Version C includes SW36 — unlimited key programming and KVM / RFA key duplication with no key tokens (SW35 NCF29A1 key duplicator for locked RFA is already included on A, A+, B, C, and C+).
What Version C adds. Version B includes DOIP programming & diagnostics via ENET on 2022+ vehicles (SW37) and replacing the RFA on a locked keyless module (SW28). HW04-C adds locked-RFA UWB keys with SW36 included — unlimited new / spare key programming (HW13 / HW14) and KVM / RFA key duplication with no key tokens — every SW36 key token you buy on B is credited 100% towards that upgrade.
Start on B. Every SW36 key token you buy is credited 100% (£ for £) towards your next tier — work your way up to C or C+ job by job instead of paying the upgrade in one go.
What each key costs on this version

HW04-B
One tool. Replace the RFA on a locked keyless module — no BCM change, no Service Mode.
Every HW04 is the same hardware. Version B adds CCF editor + as-built flashing, SDD / Pathfinder module VIN programming, New RFA programming, DOIP via ENET on 2022+ vehicles and Replace RFA on a locked keyless module (SW28) — swap the RFA alone, no BCM change, no Service Mode. On the older KVM system (roughly 2010–2018+), unlocked modules are OBD-only, while locked FK72 / HPLA KVMs use SW34 (£100 token) with Lock50 HW05/HW06 Change-ID keys to duplicate keys without removing or swapping the module. On the newer RFA system — especially where UWB is switched on — if the RFA is locked you also make a quick connection to the RFA itself to authorise the immobiliser; the key is still read and programmed over OBD — no soldering and no removing parts. On Version B the token is per key you program (SW36 £400); key copying (SW36 Key duplicator RFA when locked 2017–2025 £400 · SW34 HW05/HW06 PCF7953 key duplicator when KVM locked 2010–2022 £100) is optional. Every SW36 key token you buy is credited 100% towards your next tier.
First 12 months of updates are free, then renew from £750 a year. Step up to HW04-C for locked-RFA UWB keys and the unlimited KVM / RFA duplicator with no tokens (SW36 included). Watch the short demo below, then use Add to Cart above to get started.
