Sometimes it may happen even in a new keyboard for a couple of keys to need real pressure in order to work. If all keys are that hard, then its your keyboard’s “policy” and you need to search for something else, but if a couple of keys differ from the rest, it’s a problem, and fortunately it’s a problem you can fix easily.

I had a key like that in my Dell KB216 Keyboard, a machine that is really popular precisely for its soft keys. What a disappointment! Well, you don’t need to get a new keyboard (although this one isn’t expensive and you can change it any time).

First remove the keycap; place some thin blade between the keycap and the keyboard’s body and push the keycap gently upwards until it’s removed. You can see now the keyboard’s membrane, which for that particular key must be somehow curved, unable to transfer pressure easily. If this part of the membrane cannot become straight, then you need to place something above it, such as a tiny peace of cotton, that will reduce the distance between the membrane and the keycap, making it easier for you to activate the keyboard when you press the key.

You may have to experiment a while by adding and removing thin cotton pieces until you find the point when the key obeys, but without reducing the travel too much, that is without making the key super sensitive and equally useless.

Enjoy!
