Avoid pressing down too firmly on the tab with the screwdriver as you work to remove the cylinder because doing so could permanently damage the lock and render it useless.

Grab a big flat-head screwdriver and use that to pry the mortise lock out if it can’t be easily removed. Enter the screwdriver into the spindle’s former location.
