Choosing the Right JLR Diagnostic Tool: SDD vs Pathfinder
Choosing the Right JLR Diagnostic Tool: SDD vs Pathfinder

JLR uses two dealer diagnostic platforms — SDD for older vehicles and Pathfinder for newer ones. Knowing which your car needs saves time, and Lock50 handles the key work either way.
SDD (older vehicles)
SDD covers pre-2017/2018 vehicles. It is being phased out but still needed for legacy models.
Pathfinder (newer vehicles)
Pathfinder covers newer models and is the current dealer platform, tied to online accounts.
Where Lock50 fits
For adding keys you do not need dealer accounts — Lock50 programs keys over OBD across both eras.
Which Lock50 Tool Do You Need?
- Add keys across both eras with the HW04-C Peace Edition.
