Meet Our Expert,
Vehicle Security & Relay Attack Specialist

Most people don’t think twice about locking their car.
What they don’t realize is that the key is still broadcasting a signal.

That signal can be captured and used to steal the car without touching the keys.
I’ve tested dozens of so called anti theft solutions. Alarms. Apps. Pouches.
Many fail the moment real relay scanners are used.

SignalBlox is different.

It physically blocks the key signal the moment your keys are inside the box.
No signal escapes. Nothing to copy. Nothing to relay.

No charging.
No setup.
Works 24/7 without effort.

If you drive a keyless entry car, this is the simplest and most effective way to protect it.
