Hertfordshire police have revealed that 17 keyless vehicles have been stolen in Potters Bar and Borehamwood so far in April.

According to officers, thieves have been targeting the vehicles, leading the Constabulary to issue advice on how to prevent thefts of this type of vehicle.

A spokesperson for Hertfordshire Constabulary said: "Cars with keyless entry unlock automatically when the key comes within a short distance of the car. This can be from inside a pocket or bag.

"Keyless car theft or 'relay theft' is when a device is used to fool the car into thinking the key is close by. This unlocks the car and starts the ignition.

"Thieves only need to be within a few metres of your car key to capture the signal, even if it’s inside your home.

"This means that even if your car and home are secure, thieves can still unlock, start and steal your car.

"When at home keep your car key (and the spare) well away from the car.


"Put the keys in a screened or signal-blocking pouch, such as a Faraday Bag and check if the bag or pouch is still working every few months.

"Reprogramme your keys if you buy a second hand car.

"Turn off wireless signals on your fob when it's not being used.

"Additional physical security such as locks and immobilisers are still highly recommended."
