Keyless Repeaters and Relay Attack Devices for Sale

A keyless repeater — also called a keyless go repeater, relay attack device or keyless repeater box — retransmits the signal between a vehicle and its smart key over a distance, letting specialists evaluate how a keyless-entry system behaves under relay conditions. KeylessRepeaterBox offers one-way and two-way repeaters, including the AKS PRO V11.1 and the updated V12.1 low-frequency kit, for diagnostics, training and authorized security research.

How a keyless go repeater works

The system consists of two blocks. The receiving block is placed near the vehicle’s door handle, the transmitting block near the smart key — in an office, a pocket or a bag up to several meters away. The blocks exchange the signal over a radio link of up to about 300 m in open space, and the car responds as if the key were next to it. For security teams this reproduces the classic relay scenario in a controlled, measurable way.
