OEM key-family guide and service
JLR OEM key types is provided as a vehicle-specific service. JLR OEM key types must be matched by hardware family, frequency, security generation and fitted KVM or RFA—not by casing alone.
About Jaguar and Land Rover OEM Key Types
JLR key families span earlier PCF7953 platforms, specialist NCF29A1 variants, fixed-ID non-UWB products and later Ultra-Wideband keys. UK applications commonly use 433 MHz, but the vehicle specification remains decisive.
This guide routes owners to the correct family page and provides a service enquiry path when the existing part number or RFA generation is not known.
What this service includes
- HW05 and HW06 PCF7953 identification
- HW13 and HW14 specialist clone-route assessment
- HW15 to HW20 non-UWB family checks
- HW21 to HW26 UWB identification
- 433 MHz and 315 MHz verification
- OEM-versus-compatible alternative explanation
The final scope is confirmed before work begins. No feature, key or module is treated as compatible solely because it looks correct or appears in a generic parts list.
When this service may be suitable
- You need to identify an existing JLR key
- A supplier has quoted an HW number
- You want to compare UWB and non-UWB functions
- A visually matching key has proved incompatible
- RFA information is available and needs interpretation
These signs help route an enquiry, but they do not replace diagnosis. Two vehicles showing the same message can require different work because their platform, software, equipment and failure history differ.
Compatibility and diagnostic checks
- Vehicle brand, derivative and model year
- Key hardware number and frequency
- RFA or KVM part and software information
- Passive-entry and button behaviour
- Whether the proposed key is new, fixed-ID or previously programmed
We preserve the complete diagnostic evidence, including the reporting module and DTC suffixes. Low voltage, damaged wiring, lost network communication or missing hardware must be resolved before programming is presented as the answer.
How the mobile service works
- Identify the vehicleConfirm the registration, VIN, exact model, year and fitted security or control-module platform.
- Verify authority and compatibilityCheck ownership where security work is involved and prove the proposed key, part or configuration is suitable.
- Diagnose before changing dataTest battery condition, communication, relevant wiring and the original fault evidence.
- Complete the agreed serviceWe combine the VIN, fitted module information and key evidence to select the correct family. Supply or programming proceeds only after the expected functions and limitations are clear.
- Validate the resultRepeat the original operating conditions, scan the vehicle and test every affected function before handover.
What to send with your enquiry
Vehicle details
- Registration and VIN where available
- Jaguar, Land Rover or Range Rover model
- Exact model year and postcode
- Whether the vehicle starts and can be moved
Fault or service details
- Number of working keys
- Exact warning wording and full DTC suffixes
- Relevant part numbers or fitted retrofit details
- Recent battery, wiring, module or key work
Photos of the current key, scan report, module labels or dashboard message can prevent the wrong part or service being selected.
Frequently asked questions
Does the HW number prove vehicle compatibility?
No. Brand application, frequency, RFA generation and key state also matter.
Which variants are normally 433 MHz?
Common UK variants include HW05-family products and the odd-numbered 433 MHz members of several later pairs, but the vehicle must still be checked.
What is different about UWB?
Ultra-Wideband supports more precise proximity detection on compatible later vehicles and requires the correct UWB-capable system.
