Purpose and function of the component

The described Mercedes AMG remote button switch belongs to the Switches, control elements, and ignition locks category and is responsible for the physical operation of the remote key functions – locking, unlocking, and other functions assigned to the housing buttons. It is mounted within the original remote housing, ensuring proper travel, tactile feedback, and reliable signal transmission to the key's electronics.

The component is dedicated to modern Mercedes models from the C118, W167, W177, and W247 families in AMG versions, which guarantees a proper fit with the housing and maintains factory ergonomics.

Design, color, and fitment

The switch has been designed as an OEM component to work with the original remote control circuit board. The construction ensures:

• precise button movement,
• stable seating in the key housing,
• appropriate rigidity and resistance to typical operational wear.

The black color of the button housing maintains visual consistency with the factory AMG key finish, which is important for both aesthetics and the legibility of markings. As a result, after replacing the switch, the remote retains the original, discreet look characteristic of the Mercedes brand.

Benefits of using an original switch

Using a dedicated button switch in a Mercedes remote offers a number of practical benefits:

• Restoration of full key functionality – correct response to pressure, reliable operation of all buttons.
• Factory fitment – no need for housing modifications, soldering additional components, or using aftermarket replacements with uncertain dimensions.
• Visual consistency – maintaining the original look of the AMG remote thanks to the appropriate color and geometry of the component.
• Economic solution – the ability to repair a worn or damaged key without replacing the entire set.

Using an OEM component in a Mercedes

For the Mercedes brand, choosing a used, original control component is often a sensible alternative to new service parts. Elements from the Switches, control elements, and ignition locks group are designed with a high durability margin, which is why a properly selected remote button switch can still provide stable, predictable performance in daily use.
