                                If the Dead Bolt will not retract
                                       December 9, 2009 rev.,rs


If you operate the thumb turn and the dead bolt will not retract. You can try working the dead bolt
back with a putty knife (This is assuming the other locking points have been retracted in the handle
operation). If not see the instruction below.

Recommended tools:
• Bent needle nose pliers
• Cordless drill, with drill bits and Phillips screw driver tip.
• Stiff punch for prying pin
• Small metal chisel
• Hammer

Because of the security of the system you will destroy the bottom gear and maybe the cylinder. Call
ahead and have a replacement at the site. Remember to get the correct finish when asking for the
cylinder.

First step is to remove the handles and trim / escutcheon plates from door.

Second step is to remove the cylinder. ( drill out screw)
        This is done by drilling next to the cylinder, right through the cylinder screw that holds it in
place. To do this you drill through the lockcase cover and the screw at the bottom of the cylinder. If
the screw is not completely drilled out, you can put a chisel on what is left and break the material
with a hammer. Since there is still some material hanging outside the cylinder you will need to pull
the cylinder out the side that was just drilled. This way the material does not hang up on the
lockcase.

Next, drill out the pin that holds the activator arm.

                                                Pin that is
                                                pivot point
                                                for activator
                                                Arm




Take you needle nose pliers and pull the arm out the cylinder hole.

Depending on Manufacturers route for the cylinder hole you may or may not be able to see the slot
for the dead bolt pin. If you can see the slot you can take your punch and pry the pin back see
diagram. If not take the new gear and see which side of the door the slot will be on. Then mark the
distance 5/8” (16 mm) up from the top of the cylinder hole (From the lockcase not the route). Drill
into the door until you hit the lockcase. Remember the hole has to be straight above the cylinder hole
cutout so you can make sure the backplates (Escutcheons from the handle) cover the hole you make.
You should now be able to pry the pin back.




                                                        Work pin from front of slot to back of
                                                        slot. You may have to push stainless
                                                        actuator arm down to allow pin to slide
                                                        all the way to the back. If you can not
                                                        see the pin at all you may need to drill
                                                        into the dead bolt for a foothold to pry it
                                                        up and back to get it started.

                                                 Dead bolt pin
                                                 needs to end
                                                 up back here
                                                 to open door.




You should now be able to push down on the handles and open the door. If the pin does not want to
move or you can not get you punch behind the pin to move it. You can drill into the dead bolt. The
dead bolt is stainless so you will only put a small countersink in it. You can then use the hole as a
point to pry on.
