Reversible Cylinders

Reversible keys can lock using both sides; this means that the key will fit into the lock and lock it regardless of which direction it is facing when it is inserted. A reversible key provides a great deal of more comfort, especially in bad lighting or for people with impaired vision. Additionally, the reversible key does not have any sharp-edged grooves. This makes carrying it in a pant pocket, for example, more comfortable.
