Components of Door Security

Keyways, deadbolts and standalones for added security

Ensuring the safe and secure access to buildings and spaces is of greater importance today than ever before. The safety of employees, customers, visitors, residents, or patients is directly related to the locks that are deployed in the building.

Products discussed include ABLOY deadbolts and the Abloy Protec system, Schlage deadbolts, Yale keypad exit trim, standalone locks from Codelocks, dormakaba and PDQ.


ABLOY USA deadbolts offer the highest security for critical infrastructure and other industries that need protection under the harshest conditions. Designed to meet and surpass the highest global standards, they feature the utmost in performance and reliability: case hardened steel cylinder housing with a 2” long bolt, 6 mm steel retaining screws, a rotating collar, reinforced steel strike box and a protective bolt shield.

Models with a standard or drive-in bolt include a double cylinder, single cylinder with thumbturn, and a single cylinder with a key lockable thumbturn, all with a key operated outside. The inside thumbturn can be locked with a proper key to ensure double cylinder security. UL listed (Burglary and a 20 min fire rating), these deadbolts fit 1-3/4” to 2-1/8” holes and are available in four standard finishes – Bright or Satin Chrome, Bright Brass PVD or Satin Brass.

The Abloy lockable thumbturn deadbolt is the best solution for many deadbolt installations.  It offers the security of a double deadbolt with the convenience of a normal single cylinder thumbturn deadbolt.  Most high security lock manufacturers try to accomplish this by selling 'captive key' deadbolts.  Captive key deadbolts generally are nothing more then a double sided deadbolt in which a key is left on the inside with a key head that looks like a thumbturn.  The major downside of this is the fact you have a working key sitting in the lock 24/7 which someone could possibly quickly borrow and make a copy of. 

The Abloy lockable thumbturn deadbolt is a far more elegant solution, being a true locking thumbturn.  It features a thumbturn on the inside like a single cylinder deadbolt and when it is in normal mode can be turned like a normal thumbturn deadbolt. 

You can then use the key to enable 'secure' mode in which it can no longer be turned by hand, completely disabling the inside thumbturn from effecting the deadbolt at all.  This allows it to function like a normal thumbturn when you are at home, but then at night or when you leave the house for an extended period of time, you can enable the secure mode to ensure it cannot be unlocked without the key.  

No matter if you have glass next to the door or a window nearby, the lockable thumbturn allows for peace of mind whenever you need it. 

The Abloy lockable thumbturn deadbolt has one other unique feature in the high security world in that it has no exposed inside screws.  The screws can only be accessed when the thumbturn is not in secure mode.  When the thumbturn is in secure mode it is impossible to remove the deadbolt from the door no matter where you have access.  

This feature along with the locking thumbturn also means that even if a burglar was able to get into your house he would not be able to open the door from the inside making it far harder for them to make off with your property as they would have to go back out the way the entered.

Abloy currently has two different systems of locks, the Abloy Protec2 and the Abloy Protec. 

The Emergency Key option allows us to specially key double deadbolts and lockable thumbturn deadbolts to make them better suited for residential or primary door environments.  An emergency key is a special key that will only open the lock from the inside, and not from the outside.   This way an emergency key can be kept near the door and in case of an emergency used to open the door to get out.  As the emergency key will only work from the inside, if it is lost you do not need to worry about someone being able to open your lock from the outside.
