At the heart of that technology suite is the \u003cstrong\u003eKEYLESS-GO push-button start\u003c\/strong\u003e — a feature that, in the W166, became central to the driving experience rather than an optional extra. After several years of daily use, the button's \u003cstrong\u003efactory finish\u003c\/strong\u003e shows the familiar signs: a worn centre face and a \u003cstrong\u003echrome ring\u003c\/strong\u003e that has lost its original lustre.\u003c\/p\u003e\u003cp\u003eThis \u003cstrong\u003edirect replacement unit\u003c\/strong\u003e restores the button to original condition and costs a fraction of what a dealer would charge.\u003c\/p\u003e\u003cp\u003eLooking to \u003ca title=\"Interior Car Parts \u0026amp; Accessories\" href=\"https:\/\/europremiumparts.com\/collections\/interior-car-parts-accessories\"\u003eupgrade the interior\u003c\/a\u003e of your car?

The \u003cstrong\u003eKEYLESS-GO start button\u003c\/strong\u003e, however, is a high-contact surface. It is used every time the vehicle moves. Over 100,000+ presses across a decade of ownership, the \u003cstrong\u003ebutton cap surface\u003c\/strong\u003e develops visible wear at the contact point, and the \u003cstrong\u003echrome surround\u003c\/strong\u003e picks up micro-scratches from key fobs, jewellery, and sleeve contact.\u003c\/p\u003e\u003cp\u003eThis is normal wear for a component at this price point.
