London consistently records the highest vehicle theft figures in the UK, with the Metropolitan Police area reporting tens of thousands of car crimes annually. Relay attacks — where thieves amplify keyless entry signals from inside your home — are now the dominant method in every London borough, from Barnet to Bromley and Ealing to Greenwich.
Vehicle theft across Greater London
Greater London spans 32 boroughs and over 600 square miles of urban and suburban territory, making it the single largest hotspot for vehicle crime in England. The Metropolitan Police Service records suggest that keyless relay theft now accounts for the majority of car thefts where access was gained without breaking the vehicle — criminals work in pairs, one standing near your front door with a signal amplifier, the other standing beside your vehicle with a relay receiver. The entire attack takes under sixty seconds.
Ford Transit and custom vans remain the most targeted vehicle type across outer London boroughs, particularly in trade-heavy areas such as Enfield, Hounslow, Ilford, and Ealing. Premium keyless SUVs — Range Rover, BMW X5, Toyota Land Cruiser, and Audi Q7 — are disproportionately targeted in south-west and south-east London. Catalytic converter theft continues alongside relay attacks, meaning vehicles can face multiple forms of targeted crime simultaneously.
The introduction of Thatcham-approved immobilisers creates a hardwire break in the vehicle’s start circuit that cannot be bypassed by relay amplification. Unlike tracking devices that notify you after theft, an immobiliser prevents the theft entirely. LockCar’s relay-cut immobiliser range installs a hidden 20-amp relay in the ignition or fuel pump circuit, requiring either a proximity tag, mobile app authorisation, or an encrypted wired PIN before the engine will start.
Metropolitan Police data shows relay theft is rising year-on-year in London. If your vehicle was manufactured after 2015 and uses keyless entry or push-button start, it is vulnerable. A physical relay immobiliser is the single most effective deterrent available.
LockCar immobiliser range for London
Every LockCar device is designed and assembled in the UK. The range covers wired analog connections for budget-conscious buyers right through to 4G-connected dashcam and immobiliser combos for fleet operators and business owners needing remote oversight. Below are the four most popular configurations in the London area.
How relay attacks target London vehicles
Modern keyless entry systems continuously emit a low-power radio signal that the vehicle’s door locks listen for. Normally, you need to be within a metre or two for the car to detect your key fob. A relay attack uses two devices: one criminal holds a scanner outside your front door or window, which captures and amplifies your key’s signal; the second criminal stands beside your vehicle holding a relay transmitter that makes the car believe your key is right next to it. The car unlocks and starts as normal.
In London, these attacks are most commonly carried out between 11pm and 4am, when vehicles are left on driveways or residential streets. The process is completely silent, leaves no physical damage, and the vehicle simply drives away. Police recovery rates for relay-stolen vehicles are low, as the cars are frequently moved overseas within hours via Channel Tunnel freight routes or broken for parts in chop-shops across Greater London.
A hardwired relay immobiliser creates an electrical break in the ignition or fuel circuit that no radio signal — no matter how amplified — can bridge. The relay requires a physical, encrypted signal from a proximity tag or mobile app to close the circuit. This is the only proven counter-measure that stops relay attacks entirely.
Mobile installation across all London postcodes
LockCar operates a mobile installation service across the full Greater London area — from the inner zones (E, N, NW, SE, SW, W) through to the outer boroughs covered by BR, CR, DA, EN, HA, IG, KT, RM, SM, TW, and UB postcodes. Our technicians come to your home, workplace, or any convenient location. There is no need to leave your vehicle at a garage or wait for an available workshop slot.
Most installations take between 45 and 90 minutes. The hardwired relay is concealed within the vehicle — specific location varies by make and model to maximise security. All wiring is soldered and heat-shrunk, not crimped, for long-term reliability. You receive a full walkthrough of the system operation before the engineer leaves, and a 12-month installation warranty is included with every booking.

Frequently asked questions
Will a LockCar immobiliser affect my vehicle warranty?
LockCar devices are installed following automotive wiring standards. The relay connects into the existing circuit using reversible connections. We recommend informing your dealership if you plan to claim warranty work on related electrical systems, though in practice the device has no effect on other vehicle systems.
Can my insurer see the LockCar immobiliser for a discount?
Many UK insurers accept additional security devices as justification for a premium reduction. Contact your insurer before booking — several will ask for a certificate of installation, which we provide. Some specialist insurers require Thatcham-approved devices; we can advise on compatibility during your consultation.
What happens if my phone battery dies and I have the app-controlled version?
All LockCar app-controlled immobilisers include a backup unlock method. Depending on your model, this is either a proximity tag, a PIN sequence, or a one-time override code obtainable from our support team. You will never be stranded by a flat phone.
Which London postcode areas do you cover?
We cover all Greater London postcodes including E, EC, N, NW, SE, SW, W, WC, BR, CR, DA, EN, HA, IG, KT, RM, SM, TW, and UB. If you are just outside Greater London, contact us — we frequently cover areas up to 10 miles beyond the M25.
How hidden is the immobiliser once installed?
The relay module is installed inside the vehicle’s cabin or engine bay in a location specific to your make and model — chosen to be inaccessible without significant disassembly. Wiring is routed behind trim panels. A professional car thief with detailed knowledge of your specific vehicle would struggle to locate it in any reasonable timeframe.
