A mobile phone key is made of metal and positioned on a faceplate, having a figure mark for a function or a number for dialing formed on a top surface of the key. The figure mark or the number is formed to protrude on or recess in the top surface of the key as a 3D configuration. The key has a support pin protruding down through the faceplate to face to an upper surface of an IC board with a proper gap so that the key may tough the IC board when it is pressed down manually, and may recover its place by a spring fitted around the support pin protruding down through a socket combined with the support pin by means of a locking ring. The key endures a long period of use, and also able to be discerned by the weak sighted and the blind by touching in using the mobile phone. So the mobile phone with the keys can have a wide scope of users.
