Have You Recently Received a Pack of Sleeping Batteries in the Post from Range Rover?

If you’ve received a set of batteries through your letterbox from Range Rover recently, you might be wondering what they are for.

These batteries, often referred to as Sleeping Batteries, are part of Range Rover’s ongoing efforts to improve vehicle security and combat car theft, particularly relay theft, which has become a common method used by criminals to steal modern vehicles.

Sleeping batteries are a new type of key fob battery designed to prevent your car keys from transmitting a signal when they are not in use.

Normally, even when your key is sitting idle on your kitchen counter or hanging on your key rack, it is constantly broadcasting a small signal. This signal can be picked up by criminals using relay theft devices to trick your car into thinking your key is nearby, allowing them to unlock and start your car without ever having the key.

Once installed in your key fob, if the key is left still for a short time, like when it’s hung up at home, the battery shuts down its signal output. This stops any signal from being broadcast, making it impossible for thieves to pick it up and use relay theft techniques. This means when you’re at home and your key is not moving, your car key effectively goes to sleep, preventing any signal from being transmitted. However, as soon as you pick the key up or start moving it again, the battery wakes up instantly and the key functions as normal.

In recent years, vehicle theft rates, especially for keyless entry vehicles, reached an all-time high.

Range Rover has taken significant steps to combat this, including introducing security update recalls, updating vehicle software, and providing customers with sleeping batteries as an added layer of security.

These initiatives have already resulted in a dramatic reduction in car theft numbers for Range Rover vehicles.

It’s important to understand that these batteries protect your car best when you’re at home, and the keys are stationary.

If you’re out shopping or walking with the key in your pocket or handbag, the key remains active and will continue broadcasting its signal as normal.

Therefore, it’s still essential to be vigilant when out and about, especially in busy shopping centres or public car parks.
