SOLUTION
A. Is latch binging due to door sag or
misalignment of latch and strike?
(See 1A and 1C)
B. Are silencers correct size?
C. Is weatherstripping causing
latch to bind?
D. Lubricate keyway. Do not use
petroleum products. Apply powdered
graphite to key and move slowly in
and out. For high security cylinders,
spray Poxylube™ into keyway and
move key in and out.
E. Key may be cut out of tolerance.
Use calipers or micrometer to check key
against specifications in Corbin Russwin
Cylinder manual. Replace key if necessary.
F. Cylinder may be improperly combinated. Dismantle cylinder (locksmiths only!),
measure all pins and compare to published factory specifications. Recombinate
if necessary.
A. Is strike out of line or is gap between door and jamb too great?
