Keyless Go Repeater AKS PRO NEW SE Multibrand Relay Attack

AKS PRO SE — Compact Keyless Relay System

AKS PRO SE is a compact two-module radio relay system designed for compatible vehicles equipped with factory-installed Keyless Go and Keyless Entry systems.

The main advantage of this version is its reduced vehicle-side module, which is three times smaller than the small module used in the standard version. This compact design distinguishes AKS PRO SE from conventional keyless relay systems.

AKS PRO SE receives and relays radio signals, extending the communication link between a compatible vehicle and its original smart key. It operates as a relay device rather than a code grabber.

Also known as a Keyless Relay Stick, Universal Stick, Long Arm, Wave or Multibrand system, the device supports vehicle unlocking, locking and engine starting on compatible configurations.

AKS PRO SE is available in two compatibility packages: Multibrand and Full.

Important: AKS PRO SE does not support UWB-equipped keys. This restriction applies to all operating modes and package configurations.

Compact Design and System Configuration

AKS PRO SE consists of two separate modules:

• Larger key-side module: Communicates with the original vehicle key.
• Compact vehicle-side module: Handles communication near the vehicle and is three times smaller than the standard small module.

The reduced dimensions of the vehicle-side module are the main distinguishing feature of AKS PRO SE.

Both modules work together to establish a radio communication link between the vehicle and the original key.

Available Compatibility Packages

3. FBS4 Mode

FBS4 mode provides compatibility with selected Mercedes-Benz and Audi vehicle systems.

• Mercedes-Benz: Supported vehicles through 2025.
• Audi: Supported vehicles through 2026.

On compatible configurations, this mode supports vehicle unlocking and engine-start functions.

Note: Vehicles equipped with UWB keys are not supported in any mode.

Key Detection and Recognition

In TOY-LEX mode, AKS PRO SE can detect and recognize compatible Toyota, Lexus and Subaru keys.

The larger module provides information about the presence of a compatible original key within its operating range.

Radio Communication and Operating Range

The specified radio communication range between the two modules is up to 300 metres.

Under typical operating conditions, the effective working distance is approximately 100–200 metres and rarely exceeds 250 metres.

Actual performance depends on the original key's radio communication characteristics, battery condition and surrounding environment.

Walls, reinforced concrete, other obstacles and radio interference may reduce the effective range. The communication margin is designed to help maintain a stable connection in environments such as parking areas and locations with physical obstructions.

The distance between the two modules and the distance between the key-side module and the original key are separate operating parameters.

Operating Principle

AKS PRO SE uses two modules to establish a radio communication link between a supported vehicle and its original key.

The vehicle-side module handles communication near the vehicle, while the larger module communicates with the original key.

Once the system is active, the modules relay the relevant communication between the vehicle and key. Available functions depend on the installed keyless system and vehicle compatibility.

Module Placement Requirements

The supplied operating instructions specify the following placement requirements:

• Vehicle-side module: Position 10–30 cm from the door handle, near the vehicle's antenna.
• Key-side module: Position within 5–7 metres of the original key, with the antenna plane aligned horizontally towards the key.
• Antenna orientation: Incorrect positioning may reduce the effective operating range.
• Optional extended antennas: Described as increasing the operating distance to the key to up to 15 metres.

The suitable position of the smaller module depends on the vehicle model and installed keyless system. Refer to the operating instructions for the corresponding configuration.

Vehicle Compatibility

The supplied compatibility information identifies the following tested vehicle brands:

• BMW
• Mercedes-Benz
