SW28 Lock50 HW04-B or C  OBD Tool JLR 2017 to 2024+ New RFA Replacement Programming to 24+ (Locked BCM L8B2 + R8E2 + M8E2 Supported)

When swapping a Remote Function Actuator (RFA) in newer Jaguar Land Rover (JLR) vehicles (typically 2017 to 2025+), the Body Control Module (BCM) is often "locked." Standard dealer tools like TOPIx Cloud usually require you to replace both the RFA and the BCM to program new keys, which is costly and time-consuming. ????️

However, tools like the Lock50 HW04 series are designed to bypass this requirement using specialized software functions.¹ Let’s look at how we can navigate this process together.

SW28 Lock50 HW04-C OBD Tool JLR 2017 to 2024+ New RFA Programming (Locked BCM R8E2 + M8E2 Supported)  

When the BCM is not been locked then its possible to swap a New RFA and adapt it to work in the Vehicle without having to have a New or Virgin BCM with SW27

However when the BCM is Locked then to Swap to a NEW RFA to Erase old keys in the RFA & BCM then its required to Swap RFA ONLY and New BCM Changes can be avoided.

After Swapping RFA and Updating the Software in the Lock50 the user then goes to the PEPS Options and runs the Command   called   " Replace RFA"

Once started the Vehicles will either complete if the BCM is not locked or will give an Error that says  

"2 Keys Required or Authentication Failed" or "Less than 2 Keys found" & this means the BCM is Locked.

If you was doing a spare key you can still swap back the Original RFA and the clients old key will still work and nothing is broken.

Now you have 3 Options to make keys in this vehicle with Locked RFA and Locked BCM.

Option 1

If BCM is Locked you can still use the SW28 Paid function to bypass it and still be able to adapt a new RFA only without a new BCM in the Special Functions.

Option 2

Also if the car has UWB you can use the SW36 Paid Duplicator option to  Make a Copy of keys without changing to a new RFA even the BCM is Locked and RFA is Locked and is a faster way to do a new Key on Lock50 Keys.

Option 3 

Use the SW30 Function and Add Oem Keys in to the Locked RFA & BCM when you have 2 working keys to add the 3rd Key and supply a OEM Key to your clients.

SW28 Solution 

You need a new RFA to use this function for 21+ Cars which have been back to Dealerships for Software updates and cannot be programmed with others tools without first putting a new BCM in the Car.

Lock50 allow you to avoid messing with BCM or having to remove it  and can program keys to a New RFA still using the HW03B adapter with HW04 Lock50 obd tools and this function only is needed is you need to erase lost keys. 

Otherwise the Key copy SW36functions is faster and the option to ADD OEM Keys in the Locked system can Allow you to give your clients exactly what they required.
