How do I unlock the keyboard of IBM Selectric III???
The Selectric typewriter has several "interlocks" that can cause the keyboard to be locked. When you turn the machine off there is a mechanism that locks the keyboard. When you turn it on the part should move and unlock the keyboard. Sometimes this part sticks and the keyboard will remain locked. When you type any character the keyboard is locked to prevent two keys trying to type at the same time. The machine locks and unlocks very fast. One keys is locked in and prevents others from working. try turning on the machine and hitting every key just a little bit harder and see if it then types. When you shift, as the ball is turning the keyboard is locked temporarily so it won't attempt to type as the ball is turning as that would damage the machine. Sometimes the shift mechanism can cause the keyboard to remain licked as the shift may not have finished it's complete cycle. Also, the return mechanism locks the keyboard temporarily when the carrier is returning to prevent you from typing when the carrier is moving backwards. Only a qualified technician can resolve those issues.
