About Sleep­ing Bat­tery

Secure your keys. Secure your car.

At 3D Autokeys, we know that los­ing or replac­ing a car key remote is stress­ful enough. That’s why we don’t just sup­ply spare and replace­ment remotes; we also offer a smarter way to pro­tect your vehi­cle from mod­ern theft threats.

Meet the Sleep­ing Bat­tery, a straight­for­ward upgrade that turns your remote into a bar­ri­er against car theft.

Why choose the Sleep­ing Bat­tery?

Built-in motion sen­sor: After 3 min­utes sit­ting still, your key’s sig­nal switch­es off auto­mat­i­cal­ly - no fid­dling, no hassle.

Blocks relay attacks: Crim­i­nals can’t inter­cept what your key isn’t send­ing. Sleep­ing Bat­tery shuts the sig­nal off before thieves get a chance.

Peace of mind overnight: While you sleep, your key does too. No sig­nal, no worries.

Afford­able pro­tec­tion: For a small upgrade, you dodge the big headache of car theft and save your­self thou­sands in the long run.

Relay Attacks: The biggest car theft threat

Relay attacks are on the rise world­wide. Thieves use inex­pen­sive devices to cap­ture and relay your key fob’s sig­nal, trick­ing your car into unlock­ing and start­ing with­out the key.

Insur­ance com­pa­nies are increas­ing­ly con­cerned, with some refus­ing to cov­er high-risk vehi­cles unless extra secu­ri­ty mea­sures are in place. The Sleep­ing Bat­tery is a low-cost, prac­ti­cal solu­tion that pro­tects your car with­out com­pro­mis­ing convenience.

One Battery. One smart upgrade.

A smarter key battery that keeps thieves locked out by automatically disabling your car key’s signal when it’s not in motion.

Help and advice

How does it work?

The Sleeping Battery puts your device to sleep when it’s not in use and wakes automatically with a tap, movement, or button press. This saves power, extends battery life, keeps your device ready, and protects against relay theft.

What is a relay attack?

Criminals use antennas to intercept and boost your key signals to fool your car into thinking you are standing next to it. This method allows criminals to open your car without using force and to also start and drive your car away with ease.

Are relay attacks common?

With 95% of motorists at risk, relay attacks are on the rise all around the world, so much so that some insurers are refusing to insure Range Rovers unless they have secure parking. Criminals can buy the devices to carry out relay attacks for as little as £80, making this a very profitable and simple to perform crime.

Can I fit Sleeping Battery myself?

Yes, fitting the Sleeping Battery is relatively simple so you can fit it yourself. If you don't want to fit the product yourself, we can fit it at our Nottingham-based head office.
