Lenovo Laptop Keys at Machina Electronics

When buying a replacement laptop key from Machina Electronics, you're getting one from industry experts with thousands of laptop repair parts in stock. If the keyboard key doesn't fit your keyboard, we work with each customer to exchange it for the correct replacement.

Laptop keys can snap off and sometimes break the plastic clips and hinge parts under the key. We hear about everything from vacuuming off keys to toddlers, dogs, and cats ripping keys off. It is easy to fix the keyboard if the sensor under the key still works when pressed. There is a cone-shaped rubber spring piece under the key that may be missing or damaged, but we include this piece with each replacement key kit.

To reattach the keyboard key, the hinge scissor mechanism is attached to the keyboard base first, and then the keycap is snapped on top. Check out our free keyboard repair tutorials using the Installation Guide link above to see how each kind of Lenovo key mechanism is attached. We strongly advise against using glue or adhesive- the irreversable mess it makes of the keyboard can always be avoided with the right repair parts.

Each Lenovo key from Machina Electronics is an original key, and we guarantee it will perfectly match your Lenovo laptop keyboard. We've supplied tens of thousands of laptop users with the right part for their keyboard, and our database keeps track of each individual key in stock, so we are able to fill every order without delay. Take a look at some of the most popular keys and thank you reponses we receive.
