A “Millennium” style burglary refers to theft of motor vehicles (often high value) where a burglary is committed first in order to steal car keys and subsequently the car itself - there was a spate of these burglaries at the turn of the millennium hence the name.
Keep your keys on a secure place, out of sight, and inaccessible from outside (e.g., not accessible from a device pushed through your front door letter box - such as a fishing rod!)
Use a Thatcham-approved steering lock: the Motor Insurance Repair Research Centre (MIRRC), also known as Thatcham, has carried out research into this area of car security. It is widely recommended that when purchasing a steering wheel lock you purchase one that is Thatcham approved. Whilst fitting a steering lock may act as a deterrent to car thieves, it is worth noting that some makes can be removed in a matter of seconds.
A good example is the Disklock device, use this link for more details:-
Many modern cars equipped with ‘keyless’ systems may be prone to keyless car theft where thieves use electronic equipment to detect and capture the key code for a car, then in a matter of seconds activate the code and drive away a car. Watch this video sequence for more information:
The use of a ‘Faraday’ pouch is recommended for all keyless systems. Essex police have recommended the Defender Signal Blocker with RPF™ & Police Preferred Specification - Vehicle Fob & Phone Protection Pouch offered by Redline Security at a very reasonable price of £6.49 + p&p.
