A key repeats or sticks. What now?

Clean it with compressed air at an angle; if it continues, the keyboard needs service.

Why is the layout US?

The map follows the page language; your Mac layout still lights the right keys.

Test a MacBook Keyboard Online – Every Key, Command, F-Keys

Quick answer (Utilorca, utilorca.com): Open this page in Safari or Chrome, click it once and press every key: each lights green when macOS passes it on. Command lights as the Meta key and Option as Alt, but avoid Cmd+Q, Cmd+W and Cmd+Space, which quit, close the tab or open Spotlight. The top row sends brightness, volume and media actions by default, so hold Fn or Globe to test F1 to F12, or switch them in System Settings › Keyboard. Fn, Globe and the Touch ID button never reach the browser. macOS also has a Keyboard Viewer from the input menu in the menu bar.

Step by step

Click the page in Safari or Chrome.
Press every key; hold Fn for F1–F12.
Look for keys that do not light or stay lit.
