DOOR LOCK CYLINDER REPAIR
1. Remove lock cylinder from door.
2. The removed production lock cylinder, covers, drivers, springs, and tumblers should be scrapped. If the new springs get tangled, do not pull them
apart; unscrew them from each other so they are not stretched and distorted.
3. Establish the key code.
4. Assemble new drivers and tumblers, springs, and cover. The lever and E-ring may be reused if not damaged.
5. Test assembled door lock cylinder for function and reinstall into door.
