A thin key that is thin but includes serrations on each of two opposite sides of a blade (). The key is associated with a cylinder lock including a rotor () with tumblers (-) retained in the rotor. The blade, which is for insertion into the rotor of the cylinder lock, includes opposite first and second wide sides (F, F; F, F) and opposite first and second narrow sides (). A first notch () is formed in the first wide side and a second notch () is formed in the second wide side. The first and second notches each have a serrated wall () engageable with the tumblers. The first notch and the second notch are spaced apart so that they do not overlap each other. The sum of the depths of the first and second notches (L, D; L, D) is greater than or equal to the thickness of the blade (L, D).
