It's The Lock Replacement Case Study You'll Never Forget
Deadbolt Lock Replacement
Over time, locks can wear out. Often jamming a key in a lock or locking and unlocking it repeatedly can cause damage to the hardware.
Rekeying your locks can solve this issue, but the new lock is a better option. New locks are hard to get jiggling and offer an updated look that will let honest people in and keep dishonest ones out.
Deadbolts
A deadbolt is the most secure option to secure your door. These locks are a lot harder to be smashed into than a lever or doorknob lock because they use a thicker bolt and sit further into the door frame. In order to ensure your home's security it is essential to check the condition of your deadbolt, and replace it if it shows signs of wear.
A deadbolt lock is one that opens with a key and a thumb-turn on either side, or it can be a double cylinder lock that requires the homeowner to use two keys to open the door. The kind of lock you select is based on the level of security you want for your home, and a locksmith can help you decide what type of deadbolt is best suited to your requirements.
If you are planning to install a new deadbolt on your own begin by getting rid of the old bolt as well as its hardware. Use a screwdriver for the two screws located on the inside of the bolt. Remove the set plate which holds the bolt in place and connects it to the door frame. It is also necessary to take off the bolt and then the strike plate on the outside of the door. Install the new deadbolt by inserting it with the latch facing upwards into the strikeplate. Then, you'll have to reattach the bolt to the strike plate and secure it using short woodscrews.
Always refer to the installation instructions that was included with the deadbolt you purchased to ensure that you're following the instructions correctly. If you're unsure about what to do, talk to an expert at your local hardware store and let them know what measurements you've taken on your door. They'll be able to guide you and show you models that work with your existing hardware. If you're using a lock with an ANSI rating then ensure that it is grade two or more. This indicates that the bolt has been tested and is in compliance with industry standards for strength and durability.
Deadlocks
Deadlocks are situations in which processes cannot proceed in their work because each process has locked a resource that another process also needs. This creates an unending loop of waiting during which the processes can't be executed (Mutual Exclusion). To avoid this problem, the operating system must be able to detect deadlocks. It should also be able to identify them when they occur.
To prevent deadlocks, it's common to assign all resources to a single category. For instance the system could divide resources into categories such as printers, memory, and CPUs. This way, all processes can access the same resources without causing deadlocks.
This method can be paired with a basic Banker's algorithm to detect deadlocks. This method checks the status of each process and when they aren't finished with their work, it is assumed that the process is locked. This method isn't 100% reliable. A programmer could still create a deadlock that the operating system cannot detect.
Another method for preventing deadlocks is to require that all processes hold and release their own resources before soliciting new ones. This allows the operating system to anticipate process requests and free up existing resources. This method prevents resource starvation but has some disadvantages such as late process inception and frequent preemptions.
Another option is to use a deadlock detection method that makes use of a queue to monitor the state of each process and its children. This kind of mechanism can be used to identify deadlocks that aren't detectable with a simple dynamic test. It is only possible to use in conjunction with operating systems that are designed to accommodate this type of fix.
Other ways to prevent deadlocks is to use a priority queue. In this, each process is assigned a numeric priority. The more priority the process has, the more likely the process will be a victim of rollbacks. This technique is great for reducing the number deadlocks, but it could result in processes with low priority being postponed indefinitely. This is the reason why it is not recommended for projects that have high priority.
Mul-T-Locks
The Mul-T Lock cylinders and deadbolts have been designed to be more secure to traditional locks. These locks are constructed using premium materials and patented technology that deter attempts to pick, bump or drill. This means you can sleep soundly knowing that your home or business is secure.

They were demonstrated in videos as being easily picked. However, the latest version of Mul-T-Lock is extremely resistant to these techniques and has stood up to the examination of experts in the field.
The key to this level of protection is the inner pin stacks. They are laid out in dimpled layers within the outer driver pin stacks. These dimples have small islands in their center which control the lifting of the pin stacks in the inner layers which allows them to reach the shearline. Once they are there, they press against the inner key-pin of the binding to set. The outer drivers are removed from the plug and the lock is opened.
This system also provides extra protection against extraction pulling attacks. This is achieved by incorporating an internal shear line, which makes the cylinder body harder to ram with an external tool. The cylinder also has a shear line on the bottom and top to protect it. This is in addition to the side and back pins, which provide additional pick, drill, and pry resistance.

Mortise Locks
A mortise is a rectangular, box-shaped device that fits inside the cutout on the front door. They are extremely popular in Europe and are available in a vast selection of styles that can be fitted to doors of all types. They can be installed flush with the exterior surface or receding into the edge. They can be opened using keys from inside or operated by turning a handle or knob from the outside.
When replacing or installing a mortise lock, be sure to read the instructions provided with the lock. A lot of mortise lock manufacturers have websites with maintenance and installation guides and parts lists. It is a good idea to visit these sites before starting any repair or replacement projects.
It is recommended to measure the mortise pocket on the door prior to starting the work. Download or purchase a template to ensure that the correct size is cut. If the pocket is too big the lock will not fit correctly and will be difficult to operate. It's also a good idea to mark the center of the hole to mark the face and edge of the door on the template with a pencil. This will prevent cutting yourself when drilling.
When the pocket is correct in size and the pocket is properly sized, a mortise lock can be put into it and bolted in place. The spindle can be screwed into to the handle or knob. The cylinder that controls the locking and unlocking functions of the lockcase could be rekeyed to match your existing keys. This allows you to use one key for every door in your house.
In a residential setting mortise locks are located on exterior doors that open onto the street or a patio. They are also commonly used in large commercial complexes. In both settings it is essential to always be proactive about security and not become comfortable, as burglars look for easy ways into businesses and homes through doors that are weak.
