INSTALLING
A DEADLOCK:
Deadlocks, or deadbolts, are installed almost the same way as locksets.
Two holes are required in the door-one for the cylinder and one
for the bolt.
Position
of the deadlock can be about 12 inches above the lockset (typical)
or about 6 inches below it. This spacing provides a "double" lock
effect one from the lockset and one from the deadlock. However,
no instructions have been cast in concrete that say the deadlock
has to be in this position. It could be at the top or bottom of
the door. The problem here may be inserting the key. Or, you could
install two deadlocks-one above and one below the regular lockset.
- Measure,
mark, and position the template for the deadlock on the door.
Then X the spot where the point of the auger bit is positioned.
If no template is furnished, measure up or down about 12 inches
from the lockset. Mark this point.
- With
an auger bit, drill the hole for the cylinder through the surface
of the door. Then, mark with a nail point the position for the
bolt and drill this hole from the edge of the door to the hole
for the cylinder. The size bit you need can vary. Check the size
on or in the deadlock package.
- Install
the bolt in the hole in the edge of the door and mark an outline
of the plate on the door edge. Remove the bolt. With a chisel,
cut a mortise for the plate. The depth of cut should be the thickness
of the plate.
- Insert
the bolt in the hole and fasten it to the door with the screws
provided.
- Insert
the cylinder, working from the keyed part (exterior) to the thumbscrew
(interior). Screw the parts together from the interior. Test the
lock with the key and/or thumbscrew.
- Locate
the strike plate as detailed above for a regular lockset. Some
deadlocks have a double strike plate. That is, the flush-mounted
plate is backed up with a reinforcing plate. If your lock has
this feature, drill the hole for the bolt and mortise for the
flush-mounted plate. Install the reinforcing plate first, using
3 inch screws driven into the jack stud. Then screw on the flush
mounted plate. If the bolt has to be extended to go into the deeper
bolt hole, adjust the cylinder and thumbscrew along the bolt where
the cylinder assembly goes through. There should be an extra hole
or slot for this.
MASTER
KEYING DATA:
If you are installing new exterior locksets at your house, you may
want to have the locks "master keyed" so one key fits all locks.
Some retailers that sell locksets have the equipment to master key.
There may be a charge for this.
To master
key a lock, one lock must be chosen. The other similar locks are
then disassembled and re-pinned to match the prime lock. Depending
on the lock manufacturer, master-keying can take an hour or several
hours to do.
