I believe what you're talking about is the set screw at the bottom edge which secures the key cylinder in place. I suggest using a type of spray lubricant like WD-40 spray it into the threads. Also, while unscrewing the set screw, try to "jiggle" the key cylinder at the same time. Maybe that will help free up the screw. |
