Activity Key
Product Overview (JLR OEM‑Spec Wearable Security‑Key Retrofit)
Activity Key delivers OEM‑spec wearable security‑key capability for DOIP‑architecture JLR Defender L663 vehicles. Many outdoor‑focused owners take part in surfing, hiking and off‑road excursions. Standard smart‑key fobs risk water damage or loss during these activities. This retrofit installs genuine JLR waterproof wrist‑band hardware so drivers can leave traditional fobs safely locked inside the vehicle.
This upgrade will not operate through hardware fit‑out alone. Technicians inspect your existing PEPS passive‑entry system hardware. Our jlrcoding specialists run full DOIP diagnostics, toggle activity‑key CCF feature flags and complete KVM‑RFA module adaptation plus authorised immobiliser key‑learn. Correct programming registers the wrist‑band into vehicle security memory and unlocks passive‑entry and passive‑start functions.
Activity‑Key Hardware & Operating Logic
The retrofit kit supplies an OEM sealed IP68‑rated activity‑key wrist‑band. The unit combines LF‑band RFID transponder and encrypted 433 MHz UHF rolling‑code transmission. It draws power from an internal long‑life lithium cell and needs no regular charging. The wrist‑band works comfortably underneath wetsuits or heavy outdoor protective clothing.
Once programming finishes, drivers use touch‑handle sensors for lock‑unlock, walk‑away locking and push‑button engine start. The instrument cluster adds the activity‑key to the registered‑key inventory list. The system follows the same factory cryptographic security rules as standard smart‑key fobs. Raw hardware cannot trigger immobiliser release until technicians complete full security synchronisation over CAN‑FD bus.
After you prepare the wrist‑band hardware, no security functions activate. All passive‑entry and start features remain offline until official KVM‑RFA key‑learn completes.
Vehicle Eligibility & Technical Pre‑Conditions
This Activity Key retrofit fits 2020‑onwards Defender L663 90, 110 and 130 chassis. Fully functional factory PEPS passive‑entry and passive‑start hardware is a strict prerequisite. At least one fully‑working original smart‑key fob must stay present during programming. Send over your VIN number first. We validate KVM‑RFA module part‑number compatibility before any work begins. Our team completes a full DOIP pre‑scan before programming.
No heavy interior disassembly is required for this retrofit. After you prepare the genuine activity‑key wrist‑band hardware, our technicians save a secure backup copy of your original CCF file. We enable activity‑key feature flags and execute the authorised PEPS key‑learn routine inside the KVM‑RFA module. Our team clears all security‑system‑related DTC fault codes after configuration finishes.
Pair local workshop hardware preparation with our global remote coding service. Remote sessions require a DOIP‑VCI or Enet Type‑C cable following jlrcoding standard remote‑service workflow. The physical activity‑key hardware must sit at the vehicle location for key‑learn execution.
Key Technical & Practical Benefits
- IP68 Waterproof Wearable Wrist‑Key: Sealed OEM wrist‑band built for water‑sports, hiking and off‑road use with zero charging requirements.
- Full PEPS Passive‑Entry & Passive‑Start: Supports touch‑handle lock‑unlock, walk‑away lock and push‑button engine‑start same as standard smart‑fob behaviour.
- Factory‑Grade Encrypted Security: Rolling‑code RFID‑UHF communication integrates with KVM‑RFA immobiliser and matches original JLR anti‑cloning security standards.
- Professional KVM‑RFA & DOIP Security Procedure: CCF backup, authorised key‑learn and DTC‑clearing work prevents security‑system warning‑light faults.
Quality Assurance & Service Notes
Every Activity Key retrofit includes pre‑service diagnostic health‑check and original CCF backup. Our technicians test touch‑handle entry, walk‑away locking and passive‑start ignition for both original smart‑fobs and the new activity‑key wrist‑band once configuration completes. Hardware alone cannot achieve full wearable‑key functionality.
Incomplete module adaptation results in missing key entries inside the instrument cluster or rejected engine‑start requests. Once fully calibrated, this OEM‑spec security‑access upgrade brings reliable hands‑free convenience for Defender L663 owners with active outdoor and overland lifestyles.
