The patented Turner Deadbolt Lock from Safety by Design is a cylindrical deadbolt that locks from the outside with one keyless turn.

When I first saw the Turner Deadbolt Lock at a recent convention, I decided to take a simple survey. Over a period of a week, I asked a number of locksmith and non-locksmiths questions regarding deadbolt usage. I asked the following three questions:

  1. Do you have a deadbolt lock on the door you enter and leave your residence?
  2. Do you lock the deadbolt using your key when you leave your residence?
  3. If the deadbolt could be locked from the outside without the key, just by turning a ring surrounding the deadbolt, would you lock it?

The overwhelming responses to the three questions were:

  1. Yes my residence has a deadbolt lock on the main door used to enter and leave.
  2. No, I do not take the time (or have the time) to lock the deadbolt unless leaving for more than the day.
  3. Yes I would lock the deadbolt if there was a way to lock without using the key.

When Safety by Design sent sample locks for the article, they included several pages of burglary information. According to a survey in the year 2000, only approximately 50 percent of homes have deadbolt locks on all entrances. Of these, only 50 percent take the time to lock them.

What if you could sell your customer a deadbolt lock that could be locked from the outside without using a key? The patented Turner™ Deadbolt Lock is a cylindrical deadbolt that locks from the outside with one keyless turn.

According to research provided by Safety by Design, only 25 percent of the population locks the deadbolt upon leaving the residence. This was no surprise as a significant portion of residential burglaries occurs during the day.

The Turner Deadbolt Lock has a spring-loaded collar. This rotating ring is part of the exterior assembly that is designed to rotate in order to extend the bolt. The collar has indents that act as finger grip positions. Rotation of approximately 90 degrees is required to extend the bolt.

The collar has two internal positions: one for right hand door applications, the other for left hand door applications. When properly configured, the carrier screw is threaded into the proper collar position. The collar is able to be rotated approximately 90 degrees in order to extend the bolt. As the collar turns, the carrier screw contacts and rotates the actuator that is located over the base of the torque blade (tailpiece). Rotating the actuator causes the torque blade to rotate, which acts like the turn knob or key and extends the bolt. See Exploded View Drawing.

The Turner Deadbolt Lock Series 100 and 200 exceeds Grade 2 standards, being equipped with a one-piece solid metal face and a solid brass bolt with an anti-saw pin. These deadbolt locks can be set to any required key system because the lock cylinders and tailpieces are of industry standard design.

The deadbolt fits into standard 2-1/8” diameter cross bore with a 1” diameter edge bore. The bolt is adjustable to accommodate a 2-3/8” and a 2-3/4” backset. The lock is designed to accommodate a 1-3/4” to 2” thick door. For 1-3/8” thick doors, finish compatible spacers are available. Also for thicker doors (up to 2-1/4” thick), long screws are available.

The deadbolt lock’s brass, six-pin tumbler lock cylinder is equipped with pick resistant mushroom pins. These deadbolt locks are available with KW1, KW10 and SC4 keyways.

For this article, I will remove the lock cylinder for a combination change and change the hand of the deadbolt. Note: The Turner Deadbolt Lock is handed; the factory default is right hand.

To remove the lock cylinder:

Step 1. Remove the two assembly screws from the rear of the exterior assembly. The Phillips head screws are located just above and to the side of the torque blade.

Step 2. With the exterior assembly laying face down, lift the locator off.

Step 3. Note location of the actuator in proximity to the carrier screw. Once noted, lift the actuator off the lock cylinder’s torque blade.

Step 4. Lift off the lock cylinder.

Step 5. Recombinate the lock cylinder. The lock cylinder is equipped with a screw-on cap with spring loaded retainer pin.
