Product Overview

When a vehicle owner misplaces every key – remote fob, valet key and spare immobiliser – the repair shop must replace three inter‑linked components. Therefore, this bundle gathers the BCM, the KVM and three 434 MHz keys together, supplies the exact part numbers and includes a step‑by‑step programming guide that follows Jaguar Land Rover’s coding standards.

All components meet JLR’s OEM specifications, so the upgrade preserves the factory warranty when a certified technician performs the coding.

Technical Application

First, the technician disconnects the battery and removes the faulty BCM and KVM from the vehicle’s electronic control network. Next, they install the new units and connect the OBD‑II port to a JLR‑approved diagnostic tool (Techstream, IDS or SX‑Tool). Then, they run the supplied coding file, which restores the vehicle’s unique security ID, re‑creates the key‑pair list and enables the 434 MHz remote frequency.

After the electronic modules are in place, the technician programs the three supplied 434 MHz keys. Because the keys use the same transponder chip as the original factory keys, they pair with the newly installed BCM without any additional hardware changes.

Key Features

• OEM‑grade BCM (part number varies by model – see compatibility matrix)
• KVM module that interfaces between BCM and remote keys
• Three brand‑new 434 MHz remote keys (one primary, two spares)
• Full coding file compatible with Jaguar Land Rover Techstream/IDS/SX‑Tool
• Warranty‑safe when installed by a certified dealer or workshop
• Ready for models built 2015‑2024 that use the 434 MHz key frequency
• Includes a PDF guide with wiring diagrams, checksum tables and programming steps

Why Choose the All‑Key‑Lost Package?

Losing every key creates a costly, time‑consuming situation. Moreover, ordering three separate parts often leads to mismatched part numbers, extra shipping fees and longer lead times.

In contrast, this bundled kit eliminates those inefficiencies, delivers the exact parts that work together, and reduces the total turnaround time to a single workshop visit.

Because the kit follows JLR’s original part numbers and coding procedures, the vehicle retains its factory‑grade security level. Consequently, customers appreciate the seamless restoration of remote locking, alarm activation and valet‑mode functionality.

Compatibility & Installation Checklist

1. First, confirm the vehicle’s VIN indicates a 434 MHz key system (most Land Rover, Range Rover, Discovery and Evoque models built 2015‑2024).
2. Second, check the existing BCM part number against the matrix provided in the PDF guide. If they match, order the replacement from this package.
3. Third, disconnect the battery, remove the old BCM and KVM, and install the new units according to the wiring diagram.
4. Fourth, connect a JLR Techstream/IDS or SX‑Tool interface to the OBD‑II port.
5. Fifth, load the supplied coding file (ALL_KEY_LOST_V1.0.act) and write it to the new BCM.
6. Sixth, program the three 434 MHz keys using the “Key Programming” routine in Techstream. Then verify each key can lock/unlock and activate the alarm.
7. Finally, re‑test valet mode, central locking and peripheral functions (e.g., wipers, lights) to confirm full integration.

If any step fails, simply re‑run the checksum verification or contact JLR technical support with the error code displayed by the diagnostic tool.

Who Should Use This Package?

• Jaguar Land Rover dealerships that want to offer a fast, warranty‑safe key‑loss solution.
• Independent workshops equipped with JLR diagnostic software.
• Fleet managers who need a reliable replacement process for multiple vehicles.
• Vehicle owners who have lost every key and prefer a single‑source, OEM‑grade fix.

Product Benefits

The kit restores complete vehicle security in one service visit, saves shipping and handling costs, and guarantees that the new BCM, KVM and keys operate as a matched set.

Additionally, technicians benefit from a documented coding routine, while customers enjoy immediate access to all remote functions.

FAQ

Do I need to replace the battery when I install the new BCM?

Yes. Disconnect the battery for at least 10 seconds before removing the old BCM to avoid voltage spikes.

Will this package void my vehicle warranty?

No. When a certified dealer or an authorised workshop uses JLR Techstream/IDS/SX‑Tool for coding, the warranty remains intact.

Can I use this kit on a vehicle that originally had a 315 MHz key?

Only if the vehicle’s hardware supports 434 MHz. Therefore, check the VIN‑derived key frequency in the compatibility matrix before ordering.

How many keys does the kit provide?

The package contains three brand‑new 434 MHz remote keys – one primary key and two spares.

Do I need any special tools besides Techstream?

You need a JLR‑approved diagnostic interface (Techstream, IDS or SX‑Tool) and a standard key‑cutting machine if you want to add a mechanical cut to the new keys.
