Ideally the lock should display horizontal for locked and vertical for unlocked. This is the accepted standard in most of the world. In actuality, this is more dependent on the manufacturer of the lock and when/where manufactured.
TLDR: All locks are different. Follow the manufacturer's instructions. If the direction is not specified, then install the lock so that it is unlocked when the thumb latch is vertical and locked when it is horizontal. The latch or key locks when turned towards the frame (strike plate) and unlocks when turned away.
Double-cylinder deadbolts can be used with a key from both sides. Vertical deadbolts operate similar to single and double deadbolts, but the lock moves up and down instead of horizontally. This orientation is more resistant to forced entry via prying with a tool such as a crowbar.
A vertical deadbolt lock is a type of door lock that is attached to the doorframe at the top rather than the side. This provides extra security against burglars, as it makes it much harder for them to pry the door open with a crowbar or other tool.
Single cylinder
This is the most common type of deadbolt used. Single cylinder deadbolts have an exterior keyhole that throws or retracts the deadbolt using a key on the outside. On the inside, you can lock and unlock the deadbolt with the thumbturn.
Vertical Lock is an architectural panel system, easily installed over open framing as well as solid substrate. A concealed clip allows the panel system to float freely over the deck with thermal movements. The individual panels snap together for ease of installation.
Opt for a deadlatch if you want to just pull the door shut and deadlock it automatically behind you. If you have a knob set and just want some extra security and the choice of when it's locked then it's a deadbolt you're after.
The deadbolt latch may be installed upside down. Remove the interior assembly and mounting plate, and look at the latch inside the door hole. If the word “UP” is upside down and at the bottom of the latch, the latch is installed incorrectly.
Basic Cylinder Locks
Deadbolts use a solid piece of metal to secure the door, while standard cylinder locks use a spring to help make it easier to lock the door. Unfortunately, the spring does not provide much security and it can easily be forced. Deadbolts, however, are still vulnerable to lock picking.
The BHMA/ANSI has three, separate grades for deadbolts, simply labeled grades 1 through 3. Grade 1 is the highest quality, and the most dependable deadbolt you can have. Grade 3 is your average deadbolt which will provide an accepted, but minimal, level of security.
Often, the latch handle is in the shape of a bar that turns. Now, there are two possible ways you can set up your lock. One is that the a horizontal bar represents the locked position and a vertical bar represents the unlocked position.
Standard Core doors have a single lock block. The side of the door that the lock block is situated is indicated on the top of the door. Standard Flush Veneer doors, the lock block is positioned centrally. Moulded doors, the top of the lock block is located 880mm from the top of the door.
It might sound silly to mention locking your door as a critical safety tip, but 34 percent of those burglars enter homes through the front door. If the door is unlocked, they can just turn the handle and walk right in! By keeping your door locked, you're already one step ahead.
Yes, deadbolts are safe. But you probably actually wanted to know if they were secure. They're about as secure as a cheap lock can be; they are mostly intended as a deterrent to someone casually wandering into your house, rather than to actually keep someone out, if they were determined to get in.
Deadbolt Lock Disadvantages
Deadbolts are stronger and more difficult to compromise than other locks, but they're not entirely impenetrable. Break-ins can still happen no matter which type of lock your doors have.
In combination with your deadbolt, your door will put up a fight against even the most forceful kicks. They're also tamper-proof and will protect your door against lock picking and lock bumping. Even if someone steals or copies your key, they won't be able to get in.
Due to the nature of the mechanism, a deadbolt will always be more secure than a doorknob. If you're reading this from home I encourage you to do a simple test: If you have a door with both a deadbolt and a doorknob, open it and then lock both locks while the door is open.
The horizontal mortice locks in this section are used to replace the old Victorian locks fitted on older properties. They provide a deeper fixing for the handle on large doors which would look more aesthetically pleasing than if the handle was fitted too close to the door frame.
This page will explain the different types of locks and the security features that should be considered. Although there are many types of locks, the four most common are padlocks, deadbolts, knob locks, and levers.
Passive Locking — Automatically locks doors and trunk/liftgate after you turn off the vehicle, exit with the key fob and close all the doors. Passive Unlocking — Determine which doors unlock upon the first press of the button on the driver's door.
