Relay Attack: Stealing the Signal Through Your Walls

A relay attack is the most widespread method used to steal Range Rovers and Jaguars in London today. Your key fob emits a continuous low-power signal. When it is sitting on your hallway table, inside a kitchen drawer, or on a hook near the front door, that signal passes through walls and can be captured by a criminal standing outside on the pavement.

Two thieves work as a team. One stands close to your front door or ground floor window with an amplifier device, capturing your fob’s signal and relaying it outward. The second stands next to your vehicle with a receiver. Your Range Rover or Jaguar detects the amplified signal, believes the key is present, unlocks itself and starts. There is no forced entry, no alarm, and no audible sign that anything has happened.

Pre-2018 Range Rover and Jaguar models are significantly more vulnerable. JLR introduced Ultra Wideband key technology in 2018 across its range, which verifies the physical location of the key rather than simply its signal, making relay attacks considerably harder on newer vehicles.

Home Burglary: Breaking In to Get the Keys

As JLR improved keyless security on newer models, some criminal groups adapted by targeting the keys directly inside the home. Rather than defeating the car’s electronics, they defeat the front door instead. Burglary committed specifically to steal car keys is now one of the most commonly reported vehicle-related crimes in London.

Organised gangs will observe a property first, noting the vehicle parked outside and identifying how to get in. They break in, usually through a rear window or unlocked back door, head straight for where keys are most commonly left, and take the vehicle. The entire process can take less than two minutes. In most cases the homeowner does not realise the car is missing until morning.

OBD Port Attack: Programming a New Key on the Spot

Every modern vehicle, including Range Rovers and Jaguars, has an OBD port fitted under the dashboard. Mechanics use it to read fault codes and carry out diagnostics. Criminals use it to programme a blank key fob to the vehicle in a matter of minutes using specialist diagnostic equipment that is widely available online.

To access the port, a thief will break a window, connect their device, programme a new key and drive the vehicle away. The cost of a broken window is considered trivial compared to the value of the vehicle. Older Range Rover models, particularly those manufactured before 2018, are most vulnerable. Fitting a physical OBD port lock is one of the most effective countermeasures for these vehicles.

Surveillance and Targeted Theft: You Are Watched Before They Act

Range Rovers and Jaguars are high-value targets that organised criminal networks plan around carefully. Before many theft attempts, gangs will spend time observing a specific vehicle and its owner, sometimes across several days. They study your routine, including when you leave and return, where you park, whether you have visible security, and which moments create a window of vulnerability.

Once a pattern is established, they act at the moment of least resistance. These are not random crimes. They are planned operations, often carried out by networks that export stolen JLR vehicles to markets in Eastern Europe, West Africa and the Middle East. The National Crime Agency notes that international export remains the primary method of disposal for stolen high-value vehicles in the UK.

Carjacking: Confrontational and Violent Vehicle Theft

Carjacking is the most direct form of vehicle theft and Range Rovers and Jaguars are disproportionately targeted because of their conspicuous value. Criminals observe a target near traffic junctions, petrol stations, supermarket car parks, school gates or residential driveways, and wait for a moment when the driver is alone and vulnerable.

Tactics range from intimidation and threatening behaviour to outright physical assault. In some reported cases, thieves use a minor staged collision to force the driver to stop and leave the vehicle. If you are confronted in this situation, hand over the keys and call 999 immediately. No vehicle is worth your safety.

Signal Jamming: Your Car Never Actually Locked

A signal jammer blocks the radio frequency your key fob uses to lock the vehicle. A thief standing nearby activates the jammer as you press your fob to lock up. The locking signal never reaches the car. In most cases neither the vehicle nor your key gives any clear indication that locking has failed. You walk away believing the car is secure. It is not.

This is particularly common in busy public locations across London, including supermarket car parks, shopping centres, petrol stations and high streets. The Crime and Policing Act 2026 now makes it a criminal offence to possess or supply signal jamming devices, with penalties of up to five years in prison.

Key Cloning: Your Fob Copied Without Your Knowledge

Criminals carrying handheld scanning devices can read the radio frequency data from your key fob at close range, whether in a queue, on public transport, in a car park or even through a bag. That data is then used to programme a cloned key, giving a thief permanent, silent access to your vehicle days or weeks later.

Older JLR keyless fobs without Ultra Wideband protection are most susceptible. UWB technology, introduced across the JLR range from the 2018 model year, verifies the precise physical location of the key rather than simply its signal, making cloning significantly more difficult. If you own a pre-2018 Range Rover or Jaguar, a Faraday pouch is essential.

Opportunistic Theft: Keys Left In or Near the Vehicle

Not every JLR theft involves sophisticated technology. A significant proportion are entirely opportunistic. Criminals walk residential streets and car parks checking door handles and peering through windows. A Range Rover or Jaguar left unlocked, running unattended, or with keys visible on the seat requires no equipment and no planning whatsoever.

Leaving your vehicle running to warm up on a cold morning is one of the most common ways JLR vehicles are stolen in London. Your insurer may also refuse to pay out if your car is stolen whilst the engine is running unattended with the doors unlocked. Check your policy terms carefully.
