Add additional key fob

Product Overview (JLR OEM‑Spec Vehicle‑Security Retrofit Service)

Add additional key fob delivers secure OEM‑level spare smart‑key enrolment for DOIP‑based JLR Defender L663 vehicles. Many owners hold only one working smart fob. Losing this single key creates expensive lock‑out and recovery risks. Aftermarket cloned keys often break PEPS passive‑entry‑passive‑start security features. If you build a complete access‑convenience setup, pair this service with our Activity Key GEN2. It adds a waterproof wearable wrist‑key alongside standard smart fobs. This service uses genuine blank JLR smart‑fob hardware. It unlocks full lock‑unlock, passive‑entry, remote functions and push‑button start via secure DOIP immobiliser enrolment.

First of all, a new blank key fob will not work simply from battery installation. Technicians verify existing working key‑fob health and LF proximity‑antenna condition. Next, our jlrcoding team runs a full DOIP diagnostic scan. We complete secure security‑access authentication for the vehicle security domain. We also perform key‑enrolment adaptation for KVM keyless‑vehicle‑module, RFA remote‑function‑actuator‑module and BCM body‑control‑module. After programming finishes, the new fob supports all factory remote and PEPS functions. It also appears on the IPC instrument‑cluster key‑management menu. For extra vehicle‑access convenience, check our Keyless entry.

Hardware & Operating Logic

This service supplies genuine blank PEPS‑compatible smart key fob, matched to your vehicle regional RF frequency. It includes all required small installation accessories. The KVM‑RFA security stack validates each fob’s unique cryptographic transponder ID. Status and key‑authentication signals travel over CAN‑FD bus toward BCM and IPC modules. Each enrolled key supports button lock‑unlock, remote tailgate trigger, passive‑entry touch‑handle access and push‑button engine start. The vehicle stores multiple valid key identities inside KVM memory. Existing working keys stay fully functional during the enrolment process. All security‑handshake behaviour strictly matches original JLR factory PEPS specifications. Even with physical genuine‑fob hardware, the immobiliser will reject the key until authorised DOIP secure key‑enrolment completes. You can combine this security‑focused service with Genuine Dash Cam for complete vehicle access and incident‑recording coverage.

Vehicle Eligibility & Technical Pre‑Conditions

This Add additional key fob service suits 2020+ Defender L663 90, 110 and 130 models. The vehicle must retain at least one fully functional original working smart‑key fob. Send us your VIN number first. We validate KVM, RFA and BCM firmware revisions before starting any security‑domain work.

Local tasks include verification of LF proximity‑antenna connections and existing‑key operational tests. No major interior trim removal is normally required. Genuine blank key‑fob hardware gets prepared for secure enrolment. Once hardware preparation finishes, we save a secure backup copy of your original KVM‑RFA security memory and CCF file. We execute authorised DOIP security access then run multi‑module key‑enrolment adaptation. Finally, we clear all security‑system‑related DTC fault codes.

You can pair local fob preparation with our worldwide remote coding service. Remote sessions require a DOIP‑VCI or Enet Type‑C cable. Follow the standard jlrcoding remote‑service workflow.

Key Technical & Practical Benefits

• Genuine OEM PEPS Smart‑Key Enrolment: Factory‑spec spare key fob retains full passive‑entry, push‑button‑start and remote‑control functions; avoids unstable cloned‑key limitations.
• Preserves Existing Valid Keys: Current working fobs remain stored inside KVM memory; no forced full‑key‑wipe operation for adding an additional spare.
• Native CAN‑FD Security‑Module Integration: KVM, RFA and BCM follow JLR PEPS cryptographic security rules; new key shows inside IPC instrument‑cluster key‑management menu.
• Professional DOIP Secure Enrolment: Secure security‑domain access plus key‑ID programming removes security‑related DTC faults and maintains stable cross‑module‑bus communication.

Quality Assurance & Service Notes

Every key‑fob addition starts with pre‑service diagnostic health‑check plus KVM‑RFA security‑memory and CCF backup. After programming, we verify lock‑unlock, passive‑entry response and push‑button‑start for every enrolled key. A blank genuine‑key‑fob alone cannot enable fully‑compliant factory PEPS key‑functionality.

Incomplete security‑access or bad key‑enrolment creates unrecognised key‑fob behaviour or persistent security‑system DTC fault codes. Once fully programmed, this OEM‑spec security‑service removes single‑key lock‑out risk. It works well for family‑shared Defender L663 vehicles, overland‑focused owners and daily‑driving commuters.
