Construction and Technical Characteristics

The key fob in this product group is based on an integrated electronic module that communicates with the car via a specifically programmed signal. Inside the housing, there is a control board, buttons for individual functions, and a space for the power source. The housing is designed to ensure a comfortable grip and intuitive access to the buttons, facilitating daily vehicle operation.

As a part identified in the inventory system by a dedicated SKU and assigned an OEM part number and interchangeable numbers, the key fob can be precisely matched to a specific car configuration. This simplifies compatibility verification based on service documentation or parts catalogs.

Brand, Condition, and Replacement Selection

The presented key fob is from a manufacturer designated as Unbranded, meaning it is not marked with the concern's logo but has been prepared as a replacement meeting specific technical requirements. The product is offered as used, which allows for reduced replacement costs while maintaining the functionality required for daily operation.

When selecting such an item, it is important to pay attention to compatibility with the vehicle's electronic system, the type of control system used, and programming requirements. Markings such as the OEM part number and interchangeable numbers can be helpful in verifying if a given key fob is the correct equivalent for a specific car model.

Integration with the Control System and Installation Aspects

Replacing a key fob in modern vehicles requires consideration of its interaction with the immobilizer, comfort module, and ignition switch. In most cases, the key fob needs to be properly programmed to the specific car to ensure correct communication with the existing electronics. For this reason, it is recommended that installation and programming be performed by a workshop with access to the appropriate diagnostic tools.

When planning service work, it is worth remembering that the key fob is part of a larger vehicle control system. In the case of extensive repairs to the security system or replacement of several control elements, it may be helpful to use a comprehensive checklist for used components – you will find it in the guide how to safely select used brake system components and other key parts, prepared for informed part selection.
