The screw may be a torx head or phillips. Remove the screw and leave the lock in the locked position. Pull it straight out. now remove the key from the new cylinder and slide it in keeping the cylinder lined up with the locked position. The cylinder will stop once bottomed out. Now put the screw back in, test it. and reassemble all the rest of the stuff you took out. jim

You CANNOT leave the tumbler cylinder in the Lock position to remove it. The key must be in the cylinder and in the "RUN" position to be able to pull the cylinder out. It is a theft deterrent.

All of the 73-78ish columns I have faced have the spring button holding the cylinder in. However, I do know '82 and up columns use a screw that holds the cylinder in.
