Northfield is in the heart of Birmingham South, within the Birmingham South region. The B31 postcode area covers Northfield and its surrounding neighbourhoods. Northfield’s position along A38 Bristol Road South makes it accessible to vehicle thieves operating across Birmingham South. LockCar brings professional Land Rover relay immobiliser installation to Northfield and all surrounding areas via a fully mobile fitting service.
Land Rover theft across Northfield
Northfield is a major residential suburb in south Birmingham with a significant number of commercial vehicle owners. The B31 postcode has experienced vehicle crime linked to the A38 corridor, with Transit vans and commercial vehicles targeted overnight alongside keyless entry personal cars. Land Rover remains one of the most stolen vehicle brands in the West Midlands and East Midlands, with 32 thefts per 1,000 registered vehicles recorded across the region. Organised relay gangs specifically target Land Rover Discovery, Defender, Range Rover and Range Rover Sport models.
Northfield’s access to A38 Bristol Road South gives organised theft rings the ability to move stolen Land Rovers out of the area rapidly. Vehicles are typically targeted between 10pm and 4am by pairs of criminals using relay amplifiers to extend the key fob signal from inside the property. Premium residential streets in Kings Norton, Longbridge, Rubery are at highest risk.
LockCar’s relay immobiliser range provides a physical break in the vehicle start circuit that cannot be defeated by relay amplification. Unlike the OEM factory immobiliser, LockCar’s system requires a separate encrypted authentication — a proximity tag, Wi-Fi signal or app confirmation — to allow the engine to start. This stops relay attacks entirely, regardless of how powerful the attacker’s amplifier is.
West Midlands Police urge Land Rover owners across Northfield to use signal-blocking key pouches at home AND a physical relay immobiliser. The pouch protects when the key is stationary; the immobiliser protects when you have your key on you but are briefly away from the vehicle. Both layers are needed.
Relay attacks in Northfield — the specifics
Northfield’s position within the Birmingham South network, with direct access to A38 Bristol Road South, places it firmly within range of organised vehicle theft gangs. Criminals operating across Birmingham South can reach Northfield, conduct a relay attack, and be on a motorway within minutes of stealing a Land Rover. This speed makes traditional anti-theft measures like steering wheel locks and tracker devices insufficient on their own.
Residential relay attacks in Northfield typically target Land Rover, BMW, Toyota and Ford Transit vehicles parked on driveways or in view from the street. Gangs work in pairs: one operator stands near the property with an amplifier to extend the key fob signal, while the other stands next to the vehicle with a relay receiver that mimics the key. The OEM immobiliser is bypassed in seconds.

How does LockCar’s immobiliser differ from the Land Rover factory-fitted one?
Factory-fitted immobilisers communicate with the key fob via radio signal — they can be defeated by relay amplification. LockCar adds a physical relay break in the start circuit that requires a separate, encrypted authentication (proximity tag, Wi-Fi signal, or app) to close. A relay amplifier cannot replicate this signal — the two systems are fundamentally different in their vulnerability profile.
Does LockCar offer fleet protection for Northfield businesses?
Yes. The LockCar Fleet Monitoring Platform (LFM) is a web-based dashboard for businesses managing multiple vehicles in Northfield. It centralises location, immobilisation status, camera feeds and trip history for every LockCar-equipped vehicle. Contact us for fleet pricing for five or more vehicles.
