Help Stop Vehicle Crime - Tips

We will do all we can to help prevent vehicle crime, and the tips below can help deter potential offenders and keep your vehicle secure.


Ensure all doors, windows and sunroofs are closed and locked when leaving your vehicle unattended. Don’t simply rely on your key fob, as some thieves use ‘jammers’ to intercept the signal between the fob and the car, leaving the vehicle unlocked and vulnerable to theft.

Don’t leave your keys lying around or visible on a windowsill at home or near a front door, where they could be hooked through the letterbox

Never leave valuables in your vehicle and keep any other possessions out of sight. Remove your sat nav and its holder and wipe away any window suction marks as these could indicate a sat nav is stored in your vehicle

If you use a vehicle for maintenance purposes, it is advisable not to leave tools or other working materials in a vehicle unoccupied or overnight, as works vehicles such as vans are commonly targeted by criminals

Never leave vehicle documents in your car, as this would make it easy for a thief to sell your car or provide a cover story if stopped by the police

Consider having anti-theft screws fitted to your number plates to prevent them from being stolen and used on another vehicle

If advertising your vehicle for sale via an auction style website, ensure its number plates are blocked out in any images you share to avoid others cloning its identity

Fit a dual band tracking device that works on both VHF or UHF frequencies and GPS signals to ensure that one tracking system will still function if criminals use GPS blocking techniques to avoid detection. Vehicles with a tracking device are often promptly recovered

When using a sat nav, protect your home by not using your actual home postcode in your sat nav or storing your postcode as 'home', to avoid thieves knowing your home address if your vehicle and sat nav are ever stolen

There is an increasing risk of motorists having their car stolen using a ‘relay attack’. One criminal uses a device to receive the key signal from inside the home, transferring the signal to a second box, which is placed alongside the car. In effect, this tricks the car into ‘thinking’ the key is there, allowing the thieves to unlock the vehicle and drive away. Although the signal can pass through doors, walls and windows, it cannot penetrate metal, so placing the keys inside a metal box, signal blocking wallet or safe will protect your vehicle from a ‘relay attack’.
