Keyless Protector – Anti-Theft Protection Against Relay Attacks
Keyless Protector is the world’s first anti-theft device for cars that protects against relay attacks without limiting the full functionality of your key fob in any way.
This is a Polish-made product developed in response to the growing need to secure vehicles from increasingly common car theft techniques.
What Is Relay Theft?
Relay theft involves intercepting and cloning the key fob signal in order to open and drive away with the stolen vehicle. One thief approaches the driver or their home and captures the signal from the key fob or remote, while a second thief uses the cloned signal near the vehicle. The car, detecting what it believes to be a valid key, allows access and engine start.
The tools used by thieves are often hidden in backpacks or suitcases (hence the name “relay theft”). This allows them to discreetly intercept the key fob signal and steal an unprotected car without drawing attention.
Anti-theft protection is essential in countering relay theft, as without it, the theft simply looks like the vehicle’s owner getting into their car and driving away—no alarms, no signs of forced entry.


What Is Keyless Protector?
Keyless Protector is an anti-theft device in the form of a clip that attaches to the key fob battery. It was created in response to the growing threat of relay theft and as a smarter, more practical alternative to less effective solutions like key pouches, Faraday cages, and signal-blocking cases.
The clip disables the key fob’s power supply after the user walks approximately 30 steps or after 3 minutes of inactivity, depending on the version.
Without power, the key fob does not emit a signal. Without a signal, the car cannot be stolen using the relay method.
What Is Keyless Protector Lite?
Keyless Protector Lite is a simplified version of the original device, designed for ultra-easy installation. All the components needed to protect against relay theft are built directly into a specially designed battery.
Instead of attaching a clip to your key fob battery, you simply replace the existing battery with the Keyless Protector Lite battery.
This version was developed to meet the market’s demand for the fastest and simplest way to protect a car against relay attacks. It offers maximum convenience with minimal installation effort.
Important Note: The Lite version provides protection for a limited time due to battery life. The standard Keyless Protector clip offers a longer usage period.
Additionally, unlike the standard version, the Lite version cannot be transferred to another key fob once the battery is depleted, as the components are integrated within the battery itself.
