Then, you will be able to install the new deadbolt by putting the bolt with the latch facing upwards into the strike plate. The bolt must be reattached to the strike plate by using short woodscrews.
Always refer to the instructions for installation that came with the deadbolt that you purchased to ensure you're following the correct steps. If you're not sure what to do, talk to an expert at your local hardware store and let them know the measurements you've taken for your door. They'll be able to guide you in the right direction and suggest models that work with your existing hardware. If you are using a lock that has an ANSI rating then ensure that it is grade two or above. This means the bolt has passed industry standards of durability and strength.
Deadlocks
The deadlock situation is one in which processes cannot proceed with their work because each process has locked a resource that a different process also requires. This results in a cycle of waiting where the processes aren't able to be completed (Mutual exclusion). To avoid this problem the operating system must have a method of detecting deadlocks. Additionally, it should be able to solve deadlocks if they occur.
A common method of avoiding deadlocks is to assign resources to a single category. A system can for instance, divide available resources into categories such as memory, printers, and CPUs. This lets all processes access the same resources, without causing deadlocks.
This method can be paired with a basic Banker's algorithm to identify deadlocks. This method checks every process's status, and if it isn't completed its work, http://mysipguru.com/question/the-history-of-lock-repair/ the process is deemed to be in a deadlock. However, this method is not foolproof. Programmers can still design deadlocks that the operating system is unable to detect.
Another method to avoid deadlocks is to make sure that all processes hold and release their own resources before making requests for new ones. This allows the operating systems to anticipate requests from processes and free up resources. This prevents starvation of resources but has some disadvantages such as late process inception and frequent preemptions.
Another method is the use of a deadlock detector mechanism that utilizes a queuing system to track the state of each process and their children. This kind of system can be used to detect deadlocks which are not detectable by a simple dynamic test. It is only possible to use if the operating systems are designed to accommodate this type of fix.
Other methods to avoid deadlocks is to use a priority queue, where each process is assigned a numeric priority. The higher the priority of a process, the more likely it is to be the victim of a rollback. This technique is useful for reducing the number deadlocks, but it can result in processes with low priority being delayed for a long time. This is why it is not recommended for high-priority applications.
Mul-T-Locks
The Mul-T Lock cylinders and deadbolts are designed to be more secure as compared to traditional locks. These locks are constructed using top-quality materials and patented technology that withstands attempts to pick, bump or drill. You can rest assured that your home or office is secure.

However, the most recent version of Mul-T-Lock is extremely resistant to these techniques and has stood against the examination of experts in the field.
Inner pin stacks are the most important to this level. These are arranged in dimpled layers within the outer driver pin stacks. The dimples are tiny islands in their middle that control the lifting of the pin stacks within them which allows them to reach the shearline. Once they have reached their shearline they will press against the inner key-pin binding to set. The outer drivers are removed from the plug, and the lock is opened.
This system offers additional protection against pulling attacks. This is achieved by adding an interior shear line which makes it harder to smash the cylinder with an external tool. The Cylinder also has a shear line at the bottom and top to protect it. This is in addition to the side and back pins that provide additional pick, drill, and pry resistance.
This system also provides extra security by making it impossible to copy. This is accomplished by requiring a Mul-T-Lock official key card and allowing only authorized locksmiths to create copies. It is extremely unlikely that someone would even attempt to copy a Mult-Lock key from a photo, because it isn't allowed without a valid card.

It is a good idea to measure the existing mortise pocket on the door before beginning the work. A template can be downloaded or purchased to make sure that the correct size is cut. If the pocket is too large the lock won't fit correctly and will be difficult to operate. Mark the center of the hole on the template for the edges and the face of the door with the pencil. This will prevent splintering during drilling.
