Key jamming crime is on the increase. Deputy Chief Constable Matt Jukesfrom the National Police Chiefs' Council recently said, "The Vehicle Crime Intelligence Unit is working closely and extensively with a number of partners, including the Home Office and motor manufacturers, on solutions to prevent this crime now and in the future." It is, however, important that vehicle owners remain vigilant and understand what they are up against.
Key jammers are very easy to buy on the internet and some are able to work from a distance of 75m – potentially it could affect a whole car park. When you press the button to lock your car, the jammer blocks the signal and the car’s doors do not lock. This leaves the vehicle unlocked for anybody then to rifle through and take any valuables or parts – including your car. This is why it is so important to manually check car doors before leaving a parked vehicle.
Fortunately, most modern cars either give a short hoot or some other signal that the doors have locked. Even so, it is wise to just check before moving away from the car.
Since jammers work so effectively, it is important to ensure that your car’s central locking system is working properly and consistently. If it shows any signs of not functioningas it should, you should have it looked at as soon as possible because it may have been tampered with or disabled. Always have the system reprogrammed immediately if you lose your keys and have replacements made.
