Purpose and function of the ignition lock

The presented ignition lock socket is a component responsible for the interaction between the key and the ignition system, as well as comfort systems in BMW 1 Series cars of the E81, E82, E87 LCI, and E88 generations. As a part from the Ignition accessories group, it is responsible for:

• mechanically accepting the key or starter insert,
• transmitting signals to control modules,
• cooperating with the vehicle's factory security systems.

Thanks to maintaining the factory design, the socket allows for the preservation of the original ignition operation logic and consistency with other BMW electronic systems.

Compatibility and replacement numbers

The ignition lock has been designed as an OEM BMW element, which means full compatibility with factory wiring, mounts, and the steering column architecture in the appropriate body versions. The presence of a dedicated part number and associated replacement numbers facilitates the selection of the correct component during service repairs and verification of compatibility with a specific vehicle configuration.

Thanks to this solution, it is possible to replace a worn or damaged ignition lock socket in a controlled manner, maintaining the operating parameters specified by the vehicle manufacturer.

Benefits of using an original ignition lock socket

Using an original ignition lock in a BMW 1 Series brings a number of practical benefits, important both from the user's and the service's point of view:

• Factory fit – no need for installation modifications, drilling, or mount adaptations.
• Consistency with vehicle electronics – correct cooperation with modules responsible for ignition, steering lock, and security systems.
• Stable operation of the ignition system – reducing the risk of starting problems resulting from an incorrect socket.
• Easier diagnostics – the service can use factory procedures and diagrams, which speeds up maintenance.

A used OEM element is also a cost-effective solution while maintaining the high quality of workmanship characteristic of the BMW brand.

Condition, installation, and service application

The offered ignition lock socket comes from disassembly and is marked as a used BMW element. This type of part is particularly useful in situations where it is necessary to replace a damaged socket after a mechanical or electrical failure, and the priority is to maintain the original vehicle specification.

During installation, it is recommended to:

• verify compatibility with the specific model and year of the BMW 1 Series,
• have it installed by a workshop with experience in BMW electronics,
• check the correct operation of the ignition and communication with modules after installation.

Such an approach minimizes the risk of problems with starting the vehicle and potential errors in onboard systems.
