Ford B-Max Keyless Entry Control Module AV1T-19G481-AAF

Ford B-Max Keyless Entry Control Module is an original component from the Electronic Control Modules and Controllers group, responsible for managing the vehicle's keyless entry system. This is a precisely engineered Ford controller that allows for convenient locking and unlocking of the vehicle without the use of a traditional key, while maintaining factory safety functions. By using an original module, full compatibility with the electrical installation and electronic architecture of the Ford B-Max is preserved.

Purpose and function of the Keyless Entry module

The presented controller has been designed specifically to support the keyless entry system in the Ford B-Max. It is responsible for communication between the key, the comfort system antennas, and other body control modules, enabling:

• remote unlocking and locking of door locks,
• authorization of vehicle access when the key is in proximity,
• cooperation with the central locking system and other comfort modules. Using an original controller allows for maintaining stable operation of the Keyless Entry system, minimizing the risk of communication errors and malfunctions of comfort functions.

Benefits of using an original Ford module

Choosing an original Ford electronic control module is a solution that technically and functionally outperforms many aftermarket replacements. The controller is factory-adapted to the CAN network architecture in the Ford B-Max, which ensures that it:

• maintains full compliance with the vehicle's software,
• facilitates diagnostics using standard Ford service tools,
• reduces the risk of conflicts with other body control modules. The original module from the Electronic Control Modules and Controllers group also offers greater predictability of operating parameters and the possibility of proper coding and adaptation in the vehicle.

Characteristics and vehicle installation

The module is designed for integration with the existing Ford B-Max electrical installation, which allows for installation in place of the factory controller. In practice, this means:

• retaining original mounting points in the body,
• compatible electrical connectors matched to the vehicle's wiring harness,
• the possibility of performing standard programming procedures at a service center or a specialized workshop. After correct coding, the module works with other comfort systems, allowing for the restoration of full keyless entry functionality after the failure of the previous controller.

Product condition and practical application

The offered item is a used original Ford controller, which in practice means real cost savings while maintaining factory build quality. This solution is particularly beneficial for:

• repairs after a Keyless Entry system failure,
• replacing a damaged module after flooding or a power surge,
• restoring full vehicle functionality after bodywork and electrical repairs. Using an original used module allows for maintaining the consistency of the vehicle's electronics, which is important both for daily comfort and for subsequent service diagnostics. If you are planning a comprehensive repair or upgrade of the comfort electronics area in your Ford and need other components from the same group, such as body control units, comfort modules, or central locking controllers, check the available parts in the Ford Electronic Control Modules and Controllers category.

Technical support and part selection

When working with vehicle electronics, correct coding and matching of controllers to the specific car configuration is crucial. In case of doubts regarding module selection, programming methods, or integration with other systems, it is worth consulting specialized materials. A good point of reference may be an article describing a practical approach to electronics repairs using dismantled parts, available at the link: Driving pleasure for years – how to take care of iDrive systems and electronic modules in BMW 3 and 5 series models using dismantled parts?. Additionally, if you are interested in the impact of using original used electronic components on the future value of the vehicle, it is worth reading the guide: Original used parts and resale value – how not to lose money?, which discusses why conscious component selection helps maintain an attractive car value upon resale.
