This video demonstrates using Lock50 tools for a 2019 Range Rover Sport PEPS car. It details removing and opening the RFA module, then using a Lock50 clip with VVDI Prog to read the D-flash data from the SPC560B60L3 chip. The extracted data is then used with the Lock50 JLR Key Tool to generate an emulator key. This emulator key successfully disables the vehicle's alarm, preparing it for new key programming with a dealer tool.

The Range Rover L405 (2013–2021) is one of the most common JLR key jobs. Lock50 HW04 tools program spare and lost keys over OBD, covering both early and locked-RFA later builds.

This video demonstrates programming two new OEM keys into a locked 2023 Range Rover Sport's RFA module. Using the Lock50 HW04-C tool connected via OBD, the process involves scanning the car, entering the PEPS key learning routine, placing keys on the reader, and then on the passenger seat as prompted by the software. The key IDs are detected, and the module is successfully updated in under two minutes, concluding with a BCM write.

A dealer Range Rover key replacement in the UK can run into hundreds of pounds — and days of waiting. This guide breaks down real costs for spare and lost keys, and shows how an independent locksmith with a Lock50 tool does the same job faster and cheaper over OBD.
More demos on the Lock50 YouTube channel.
A main-dealer spare key is typically the most expensive route once you add the key, programming and any recovery. An independent locksmith using a Lock50 HW04 tool programs the same key over OBD, usually at a fraction of the time and cost.
Cost depends on whether it is a spare (one key still works) or all keys lost, the model year, and whether the RFA is security-locked. Newer UWB models need a UWB-capable tool, which Lock50 provides.
Dealer prices are the highest; an independent locksmith with a Lock50 tool typically does the same spare or lost-key job for far less over OBD. Exact cost depends on model year and whether keys are lost.
Usually yes. Lock50-equipped locksmiths program keys over OBD without dealer overheads.

This video demonstrates programming a spare key for a Land Rover vehicle using the Lock50 JLR Key Tool 1.3.11.0. The process involves connecting the tool to the vehicle's RFA module, collecting data, and then duplicating an existing key by placing it on the programmer. The operation is shown to be successfully completed, programming a new key for a locked RFA module on 2024+ models within two minutes. The service is offered by Lock50 in Birmingham, UK.

JLR key security centres on two modules: the KVM (Keyless Vehicle Module) and the RFA (Remote Function Actuator). Knowing the difference tells you which job — and which tool — you are dealing with.
More demos on the Lock50 YouTube channel.
The RFA authorises keys and keyless entry/start. On newer cars it is security-locked and must be unlocked before adding keys.
Earlier or different-market vehicles use a KVM performing a similar role. Lock50 supports reading and programming both.
Both authorise keys; the RFA is used on most modern JLR vehicles and is often security-locked, while KVM appears on earlier/other-market cars. Lock50 supports both.

This video demonstrates using a specialized programmer tool, likely the Lock50 HW53 SPC560B60L3 RFA, to make a JLR (Land Rover) KVM module virgin without soldering. The process involves erasing and unlocking the 9S12 MCU, adjusting data partitions, and then loading virgin D-FLASH, EEE, and P-FLASH files onto the module. This enables key programming for Land Rover vehicles from 2010-2018 (KVMS) and 2017+ (RFA) without component removal.

A dead key fob battery is the most common Jaguar/Land Rover key 'fault' — and the easiest to fix. Here is how to swap it yourself, and when the problem is actually the key, not the battery.
Slide out the emergency blade, split the fob at the seam, lift the old cell and fit a fresh CR2032 the correct way up. Clip it back together and test.
If a new battery does not help, the key may be damaged or de-synced — that needs re-programming, which a Lock50 technician handles quickly.

Programming a key for a modern Jaguar or Land Rover is no longer a dealer-only job. With the right tool you can add a spare key, handle an all-keys-lost situation, or replace a locked module yourself — often in minutes rather than hours. This guide explains how JLR key programming actually works, what changed with newer security, and which Lock50 tool fits your workshop.
More demos on the Lock50 YouTube channel.
Every Jaguar and Land Rover built since roughly 2010 uses a PEPS (Passive Entry Passive Start) system. The key talks to the car's RFA (Remote Function Actuator) and BCM (Body Control Module), which together decide whether a key is allowed to start the vehicle. To add or erase a key you must communicate securely with these modules — that is exactly what a JLR key programming tool does over the OBD port.
Older methods meant removing the RFA or BCM from the car and reading it on the bench. Modern Lock50 tools do the whole job through the OBD port with no module removal on most 2010–2024 vehicles — faster, cleaner, and far less risk to the customer's car.
Lock50 offers a clear upgrade path so you only pay for what you need:
Yes. With a Lock50 HW04 tool you can add a spare key or handle all keys lost yourself through the OBD port, without dealer login.
A spare key is typically added in a few minutes. All-keys-lost and locked-RFA jobs take longer but are still far quicker than module removal.
Yes — the HW04-C+ kit supports the newest UWB models including locked RFA programming and EVA2 unlock.
