Add additional key fob

Product Overview (JLR OEM‑Spec Smart‑Key Programming Service)

Add additional key fob delivers specialist DOIP security programming for DOIP‑architecture JLR Defender L663 vehicles. Many households want a spare smart‑key fob for multiple‑driver use or emergency backup. The L663 PEPS passive‑entry system uses encrypted UWB ultra‑wide‑band security. A simple physical key‑fob copy will not start the vehicle without official module programming. This service handles the software‑side registration for your prepared blank smart‑fob hardware.

This service does not supply physical key‑fob hardware. You source and prepare the UWB‑capable smart‑key beforehand. Our jlrcoding technicians run DOIP security access, complete KVM/RFA keyless‑vehicle‑module adaptation, execute immobiliser synchronisation and clear temporary DTC faults. Correct programming writes the new fob identity into vehicle security memory while it preserves all existing registered keys.

Key‑System Hardware & Operating Logic

The Defender L663 KVM/RFA module stores registered smart‑key identities inside non‑volatile onboard memory. Each genuine UWB smart‑fob transmits encrypted rolling‑code radio‑frequency data. The vehicle validates cryptographic challenge‑response before it grants door‑unlock and engine‑start authorisation.

After successful programming, the extra key fob supports every factory function: passive entry, passive start, remote lock‑unlock, boot release and panic‑alarm. Your original working keys stay fully functional and the process never erases them. Unprogrammed blank fobs only deliver manual emergency‑blade mechanical unlocking; they cannot trigger immobiliser release for engine ignition.

Even with a physically cut emergency blade, the new fob cannot communicate with immobiliser until technicians complete official KVM/RFA key‑learn procedure over the CAN‑FD vehicle bus.

Vehicle Eligibility & Technical Pre‑Conditions

This Add additional key fob service supports 2020‑onwards Defender L663 90, 110 and 130 chassis. At least one fully‑working original UWB smart‑key fob must stay present during programming sessions. Send us your VIN number first. We run pre‑service validation to confirm key‑blank hardware compatibility for your build.

Vehicle battery voltage must hold stable above 13.5 V through the full programming workflow. Our technicians run a full DOIP pre‑scan before security‑access operations. We create a backup of your original CCF file, run authorised key‑learn routine inside KVM/RFA module, sync immobiliser parameters and clear temporary security‑related DTC faults once configuration finishes.

You can book local workshop support or choose our global remote coding service. Remote sessions require a DOIP‑VCI or Enet Type‑C cable following jlrcoding standard remote‑service workflow. The new physical key‑fob hardware must sit at the vehicle location for key‑learn execution.

Key Technical & Practical Benefits

• OEM‑Level Spare‑Key Registration: Adds extra UWB smart‑fob into factory KVM/RFA memory and keeps all your original smart‑key‑fob functions intact.
• Preserve Existing Working Keys: This add‑key workflow registers new key‑ID entries and never deletes your current working smart‑key fobs from vehicle security storage.
• Full PEPS System Integration: Enables passive‑entry, passive‑start, remote buttons and immobiliser engine‑start authentication for the new spare fob.
• Professional KVM/RFA & DOIP Security Procedure: Secure authorised access, CCF backup and post‑programming DTC clearing so you avoid security‑system warning‑light faults.

Quality Assurance & Service Notes

Every Add additional key fob programming session includes pre‑service diagnostic health‑check and original CCF backup. Our technicians perform full post‑programming verification. They test lock‑unlock, passive entry, panic‑button and engine‑start operation for old and newly‑added key fobs.

This service covers software‑side security registration only. It cannot repair damaged KVM/RFA hardware or fix faulty key‑fob electronics. Physical key‑blank supply plus emergency‑blade cutting sit separate from this programming service. Once fully programmed, your extra smart‑key fob delivers reliable backup convenience for multi‑driver Defender L663 households and travel‑focused owners.
