Purpose and function in the vehicle

The presented lock is designed for installation in the front right door, which is crucial for the proper operation of the entire locking system in the Audi A4 S4 B7. It is responsible for:

Construction and technical advantages

The lock barrel with cylinder and coil has been designed for seamless cooperation with the factory Audi key. The construction provides:

• a precision cylinder compatible with the key profile,
• a coil responsible for proper communication within the mechanism,
• a housing adapted for mounting in the front right door structure.

This solution allows for maintaining the original vehicle locking and unlocking functionality without the need to interfere with other door system components.

Condition of the item and service application

The offered lock comes from the group of used Audi components, making it an attractive alternative for service repairs when replacing the entire door module is not required. It is particularly useful in situations where:

• it is necessary to replace only the component responsible for key interaction.

Selecting the correct lock for the specific model and side of the vehicle allows you to limit the scope of workshop work and focus on replacing a single, specialized sub-assembly.
