Activity Key GEN2 Retrofit – Wearable Waterproof Vehicle Access for Land Rover & Range Rover

Leave the traditional key fob behind and embrace a fully active lifestyle with the genuine JLR Activity Key GEN2. This second‑generation wearable device provides complete keyless entry, push‑button start, and passive vehicle locking, all in a compact, shock‑resistant wristband designed to accompany you during water sports, trail running, cycling, or any outdoor pursuit. The kit is engineered to integrate directly with your vehicle’s Remote Function Actuator (RFA) and Body Control Module (BCM), replicating every function of the original factory option.

How the Activity Key GEN2 System Works

The Activity Key GEN2 utilises a passive RFID transponder operating at 125 kHz and an active UHF transmitter on 433 MHz (market‑dependent) to communicate with the vehicle’s keyless entry system. The wristband itself contains no battery; the GEN2 module is powered by an integrated, long‑life lithium cell that is sealed within the shock‑resistant silicone strap. When the driver approaches the vehicle, the RFA module detects the Activity Key’s unique identifier, validates it against the stored security credentials, and permits door unlocking via the capacitive touch sensors on the door handles. Once inside, the vehicle recognises the key and allows engine start via the start/stop button.

A critical improvement over the first‑generation Activity Key is the GEN2’s ability to support full passive entry, passive start, and passive locking – the vehicle locks automatically when the key moves out of range, and the engine can be started without requiring the key to be placed in a specific location. The wristband is rated IP68 for continuous immersion in water up to 30 metres, making it safe for swimming, diving, and other sub‑aquatic activities. The silicone strap is also resistant to salt water, UV radiation, and common chemicals.

Programming the Activity Key into the vehicle is performed via the JLR diagnostic tool (Pathfinder) by updating the Car Configuration File (CCF) and authenticating the new key in the immobiliser and RFA modules. The system can store up to four Activity Keys alongside the conventional Smart Keys, and each key can be individually enabled or disabled through the touchscreen.

Key Technical Benefits

Full waterproof capability – IP68 rating allows continuous submersion, so you can swim, surf, or paddle without worrying about the key.
Passive entry and start – Unlock the doors by touching the handle, start the engine with the push‑button, and walk away to lock; no need to press any buttons on the wristband itself.
Zero battery anxiety for the band – The GEN2 module uses a sealed lithium cell with a typical life of 5–7 years; there is no charging port, and the unit is replaced when the battery is depleted.
OEM keyless security – Encrypted UHF communication and rolling‑code RFID prevent relay attacks and cloning; the key is authenticated to the same standards as a factory Smart Key.
Seamless integration with vehicle settings – Once coded, the Activity Key appears in the instrument panel key list and can be managed via the touchscreen, including disabling the conventional keys for added security.
Ergonomic and discreet – The slim silicone strap fastens securely to the wrist with a simple clasp, and the module is unobtrusive enough to be worn under a wetsuit or cycling gloves.

Included Components

The complete retrofit kit contains all genuine Land Rover parts required for installation:

Activity Key GEN2 wristband module (pre‑programmed blank, VIN‑matched after coding)
Silicone strap with clasp (choice of colours available, standard black)
RF antenna interface module (if required by vehicle hardware level)
Wiring harness and connectors for the RFA module (where applicable)
Installation guide and CCF modification template

All components are supplied in sealed Land Rover packaging and are identical to the factory‑fitted option. The kit does not include a conventional Smart Key; the Activity Key GEN2 is intended to supplement, not replace, the standard key fobs.

Compatible Vehicles

The Activity Key GEN2 retrofit is available for JLR vehicles equipped with the latest keyless entry architecture (Remote Function Actuator module with UHF and passive LF antennas) and Pivi Pro or InControl Touch Pro infotainment systems. The following models are supported:

Model	Platform Code	Model Year from
Range Rover	L460	2022 onward
Range Rover Sport	L461	2022 onward
Range Rover Velar	L560	2021 onward (MY21.5+)
Discovery 5	L462	2021 onward
New Defender	L663	2020 onward (with 10″ infotainment)
Range Rover Evoque	L551	2021 onward (with passive entry)
Discovery Sport	L550	2021 onward (with passive entry)

Compatibility is verified on a VIN‑by‑VIN basis. Some vehicles may require a supplementary antenna or module update; we will check your specific hardware configuration before dispatch.

Installation Notes

The retrofit process is predominantly software‑based, with minimal physical installation required on most vehicles equipped with the correct RFA module. The steps include:

Connection of the JLR diagnostic tool (Pathfinder) to the vehicle’s OBD port and verification of the existing RFA, BCM, and Gateway module software levels.
If required, installation of the additional RF antenna interface module and its wiring, typically behind the rear quarter trim panel or in the roof console area.
Programming of the Activity Key GEN2 into the vehicle’s security system – this involves updating the immobiliser, RFA, and KVM (Keyless Vehicle Module) configurations with the new key’s unique encrypted ID.
Modification of the Car Configuration File (CCF) to enable the Activity Key feature in the touchscreen and instrument cluster menus.
Functional testing of passive entry, passive locking, and passive start using the wristband.

lr‑retrofit.com offers professional installation at our workshop, with the entire programming process typically completed in under two hours. Remote coding support is also available for customers who wish to perform the physical installation themselves.
