If the key is stuck, gently insert a spudger under the edge of the keycap.

Start from one corner and carefully pry the keycap from the keyboard, working your way around it until it pops out.

Inspect the key mechanism (scissor switch under the keycap) for any damage or debris.

If the keycap is dirty, clean it by soaking it in warm soapy water.

Ensure the key mechanism and cap are dry before reassembling.
