Smart Keyless Keeper Device
The Smart Keyless Keeper helps protect cars with keyless entry from relay theft. It fits inside your key fob and switches the key off when it isn't moving, so there's no signal for thieves to pick up, and you keep the convenience of keyless entry.
- Fits inside your key fob
- No change to how keyless entry works
- Simple DIY fitting
- Doesn't drain the key battery
What is a passive keyless entry system, and how does it work?
Older cars used active keyless entry: you pressed a button on the key fob to unlock the car. Passive keyless entry, now fitted to most modern cars, unlocks the car as you walk up to it, with no buttons to press.
It works by radio. Your key fob keeps sending a unique code, and the car keeps listening for it. When the car hears the right code, usually within about 5 to 20 metres, it unlocks and lets you start the engine.
What is a Relay Attack?
The same technology can be used against you. In a relay attack, one thief stands near your house with a device that picks up your key fob's signal and boosts it. A second thief stands by your car with a receiver, so the car thinks the key is right next to it and unlocks.
It can happen while the car is parked outside your home overnight, or while you're having dinner in a restaurant.
How Does the Smart Keyless Keeper Device Work?
The Smart Keyless Keeper is a small chip that wraps around your key fob's battery and has a built-in motion sensor. When the key has been still for a while, for example on the side at home overnight, it switches the key off so it stops sending its signal.
As soon as you pick the key up and walk to your car, it switches back on, so you can unlock and start the car as normal.
How to fit it
Fitting is as simple as changing the key fob battery: open the fob, wrap the chip around the battery and close it again. Need a hand? There are battery-change videos for most models on YouTube, or contact our UK team.
What Makes the Smart Keyless Keeper Device Unique?
There are other ways to stop relay attacks, such as silicone cases and Faraday boxes. Here's how they compare.
Silicone case
Low cost, but depending on how the key sits, the signal can still leak through, and you have to take the key out to use it.
Faraday box
Blocks the signal well at home, but only while the key is inside it. Forget to use it, or leave the house, and the key is exposed again.
Smart Keyless Keeper
Works automatically. It switches the key off when it has been still for a while and back on when you move, at home or out and about.
