Jaguar & Land Rover key type service
Land Rover HW15 HW16 key is provided as a vehicle-specific service. HW15 and HW16 are Land Rover OEM non-UWB NCF29A1 key families. HW15 is 433 MHz; HW16 is 315 MHz.
About HW15 and HW16 OEM Keys
These are fixed-ID keys. On compatible non-UWB applications, locking and unlocking is normally button-operated rather than passive keyless entry.
We confirm RFA compatibility, correct frequency and key status before programming. Once programmed, a fixed-ID key is dedicated to that vehicle.
What this service includes
- Vehicle, model year and security-platform identification
- HW15 and HW16 OEM Keys specification, part and frequency checks
- Main-battery, KVM or RFA communication checks before programming
- The correct supply, programming or diagnostic route for the vehicle
- Remote buttons, passive entry, emergency access and starting tests
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 a correctly matched spare or replacement key
- The existing key is damaged, intermittent or no longer recognised
- Remote locking, passive entry and starting do not all behave the same way
- You want compatibility confirmed before buying a key
- A key or security-module fault needs to be separated from low voltage or antenna problems
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
- VIN, registration, model and exact model year
- Key frequency, hardware family and new or previously programmed status
- Number of keys currently authorised by the vehicle
- KVM, RFA, BCM and immobiliser communication where applicable
- Relevant aerials, wiring, battery condition and complete DTC suffixes
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 confirm RFA compatibility, correct frequency and key status before programming. Once programmed, a fixed-ID key is dedicated to that vehicle.
- 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

Photos of the current key, scan report, module labels or dashboard message can prevent the wrong part or service being selected.
Frequently asked questions
Can appearance confirm compatibility?
No. A matching case and button layout do not prove the electronics, frequency or security generation are correct.
Can a vehicle fault look like a key fault?
Yes. Low voltage, antenna faults, wiring damage and KVM or RFA communication issues can prevent a valid key being detected.
What should be tested after programming?
Remote buttons, passive entry where fitted, cabin detection, emergency access and reliable starting should all be checked.
