Car thieves are a constant threat for motorists.Keeping your car secure will not only deter criminals but could also result in lower car insurance premiums.

In This Guide:

Vehicle tracking

An increasingly popular car security device, vehicle tracking systems sit inside your car and allow you to monitor its location via GPS should it go missing. While this won’t prevent your car from being stolen, it will vastly increase the chances of you being able to locate it with the help of the police. It’s worth exploring different vehicle trackers as the more high-tech options will omit signals on multiple frequencies to assist tracking.

Security camera

A conspicuously placed camera should do a good job in dissuading even the most determined of car thieves. Best placed in a visible location as a deterrent, yet inaccessible so it can’t be easily disabled.

Key protectors

With key technology constantly evolving, keyless car theft is becoming one of the most common forms of vehicle theft. Relay devices can be used to increase the range of your key fob, meaning your car can be unlocked even if your keys are in your possession or home. Keeping your keys in a blocking pouch (widely available) inside your pocket or in a secure metal box at home are both recommended.

Vehicle immobilisers

Cars manufactured since 1998 that are sold in the UK will legally require some form of immobiliser to be fitted. If your car is older, having an immobiliser fitted is highly recommended as it prevents the engine from being initiated, making it a fantastic security device.
