1. The door should be flush and free of any lock hardware. Patch and repair the door as
required before proceeding. The door should open and close easily.
2. With the door closed, make a mark on the inside surface of the door 41” up from the
finished floor. This mark will locate the top edge of the inside Mounting Plate.
3. Keeping the door closed, place the inside mounting plate against the inside surface of the
door - aligning so that the top edge of the mounting plate is even with the mark made in
the previous step and the
jamb-side edge is even
with the stop on the door
jamb (See Figure 1).
NOTE ON CHANGING THE HAND
The Sur-Lock™ is designed to be
used in both left-hand reverse and
right-hand reverse applications. It is
shipped pre-configured for left-hand
reverse use. See Appendix A for
instructions on reversing the hand.

For Solid-Core Wood Doors proceed to Step 5, otherwise for Hollow Metal Doors
continue.
4. Attach the outside mounting plate by repeating steps 2 & 3. The outside mounting plate
must align with the inside mounting plate - transfer your measurements from the inside
mounting plate carefully (See Figure 2). Secure the outside mounting plate with the six
(6) self-drilling torx screws.

To change the hand of the device, see Appendix A
5. Using the square holes in the inside mounting plate as guides, drill five (5) holes into the
door (See Figure 3):
For Solid-Core Wood Doors
DO NOT DRILL ENTIRELY THROUGH THE DOOR!
Drill 5/32” holes 1-1/2” deep into the inside door surface.
For Hollow Metal Doors
Drill 1/4” holes entirely through the door. The holes must be straight so that your drill
bit exits the opposite surface of the door through the matching square hole on the
outside mounting plate.

6. Mount the Sur-Lock™ to the inside surface of the door (See Figure 4).
For Solid-Core Wood Doors
Discard the carriage bolts and use five (5) #14 1-1/2” lag screws to fasten the SurLock™ to the inside door surface.
For Hollow Metal Doors
Attach the Sur-Lock™ using the five (5) carriage bolts and lock nuts supplied. The
heads of the carriage bolts must be on the outside door surface and the lock nuts
must be on the inside.
DO NOT OVER-TIGHTEN THE LOCK NUTS ONTO THE CARRIAGE BOLTS AS DOOR
WARPING MAY OCCUR.

7. Keeping the door closed, check the distance between the end of the lock bolt and the
door jamb stop. To ensure the maximum extension into the latch (installed later), the end
of the lock bolt should just clear the jamb stop - the clearance should be approximately
1/16” but no more than 1/8”. If necessary, adjust the extension of the lock bolt rod by
loosening the jamb nut at the opposite end of the lock bolt rod - inside the Sur-Lock™
housing - and rotate the lock bolt rod as needed to obtain the proper clearance. Tighten
the jam nut securely (See Figure 5)!

8. With the door closed, slide the latch over the lock bolt rod, making sure it latches. Mark
around the outside of the latch and open the door. Remove the paper backing from the
adhesive tape on the back of the latch and temporarily affix it to the jamb stop - aligning
with the marks. Fasten the latch to the jamb stop with two (2) self-drilling torx screws
through the two (2) slotted holes in the latch (See Figure 6). Verify that the lock bolt fully
latches into the latch and extends fully. If necessary, make additional adjustments by
loosening the two (2) self-drilling torx screws and moving the latch. Make sure the door
closes and locks smoothly and securely. Tighten the two (2) self-drilling torx screws.
Once you are satisfied with the adjustments, secure the latch to the jamb stop with the
remaining four (4) self-drilling torx screws.
DOOR CLOSER MAY REQUIRE ADJUSTING.

9. With the door closed, measure 39-1/2” from the finished floor up the inside of the door
and make a mark. Using the mark, align the hinge-side deadbolt template by folding and
placing the solid line against the inside hinge-side of the door. Using a center punch,
make two (2) center marks on the face of the door, and one (1) on the door jamb stop.
For Solid-Core Wood Doors
Drill two (2) holes in the door, making sure they are level. DO NOT DRILL ALL THE
WAY THROUGH THE DOOR! Next drill a small pilot hole on the mark in the door
jamb stop. Then drill a 9/16” hole using the pilot hole in the door jamb stop. Finally,
discard the outside mounting plate and the supplied carriage bolts. Install deadbolt
using two (2) #14 1-1/2” wood screws.
For Hollow Metal Doors
Drill two (2) holes in the door all the way through, making sure they are level. Then
drill a small pilot hole on the mark in the door jamb stop. Then drill a 9/16” hole
using the pilot hole in the door jamb stop. From the outside of the door, install the
deadbolt mounting plate using two (2) supplied 1/4” carriage bolts by pushing
through the plate and door. Install deadbolt on 1/4” carriage bolts on the inside and
secure with locknuts (See Figure 7).

10. Remove the backing paper from the bolt plate and align with the 9/16” hole on the door
jamb. Temporarily hold in place with tape and check the alignment of the bolt plate
and the hinge-side deadbolt by closing the door. Make sure the hinge-side deadbolt
moves in and out of the hole freely. Then secure the bolt plate to jamb with two (2) selfdrilling torx screws.
THE HINGE-SIDE DEADBOLT SHOULD EXTEND 1/2” INTO THE BOLT PLATE.
11. Once you have checked the alignment in the previous step, secure the lock bolt plate to
the doorjamb with two (2) self-drilling torx screws. Finally, open and close the door
making sure the door operates freely.
12. Install the 9 volt battery on the battery bracket
assembly (See Figure 8).
13. Connect the wire from the switch on the inside of the alarm assembly cover to the circuit
board (See Figure 9).

14. While holding cover plate in place, wait 15 to 20 seconds, then open door. The alarm will
sound. The alarm will continue to sound until the key is turned to the off position. To do
this, insert the key into the cylinder and turn counter-clockwise until the key stops (See
Figure 10). The alarm should cease.
Note: On the Sur-Lock™, the alarm is set
15 to 20 seconds after the key is rotated
back to the vertical position. The cylinder
is key retaining when the unit is
disarmed.
15. If the Sur-Lock™ being installed is equipped with a counter, rotate the knob on the left
side of the counter until it reads all zeroes (See Figure 11). After checking for complete
proper device function, install all covers with self-drilling torx screws.

A-5. Reposition the clip that secures the battery wires to the unit, using caution so as to not
pull the battery wires out of the Alarm Board (See Figure A.5). The clip should be
positioned on the same side as the Battery Bracket Assembly. If the Battery Bracket
Assembly’s location is now on the left of the unit, route the battery wires below the
Alarm.
A-6. If the Battery Bracket Assembly is located on the left side of the unit, route the battery
wires through the metal channel and up to the battery (See Figure A.6).
