SW27 Lock50 HW04-B & C OBD Tool JLR 2017 to 2024+ New RFA Programming (UnLocked BCM Supported)
Mostly BCM are Unlocked unless the Dealer has applied the Latest Updates to Lock then Down.
The Locking of the BCM starts from 2017 up to 25+ Vehicles and mostly 21+ are Locked always.
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.
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" when BCM is Locked.
If BCM is Locked you can still use the SW28 function to bypass it and still be able to adapt a new RFA only without a new BCM.
Also if the car has UWB you can use the SW36 Duplicator the 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.
