![]() It is advisable to check with the company’s insurance company about changes otherwise, problems may arise in the event of loss or damage. Depending on the current business organisation structure, which may also have a significantly higher security requirements than before, this replacement is even more imperative. Replacing a locking system and its master key with digital locking technology would make sense in such cases. Expansion capacities may even be fully exhausted after such long periods. If a company’s organisational structure has been changed, locking systems with master keys can often only be adapted to a limited degree. Master keys, master group keys and locking cylinders in systems, such as those from the 80s or 90s, are subject to certain signs of wear due to heavy use, which can also have a negative impact on the security status. During a service life of 20 years or more, keys, including master keys, are always being lost and do not reappear anywhere, thus posing a major security risk. WHAT IS A MASTER KEY SYSTEM Plain and simple, a master system allows you to have different levels of access to each lock and to be controlled by one key. This may create serious problems if these are master keys with a superordinate function. Keyed Alike: A number of locks operated by the. After the patents expire, master keys for such systems can be legally copied anywhere without needing to show the security card or certificate. Keyed to Differ:Individually keyed locks only opened by their own key. Patents on cylinders and keys are only granted for certain periods of time, for example. Older locking systems with a master key may pose certain security risks which users are often not fully aware of and which make it easier for miscreants to go about their "business". Even if the cylinders are still working, there are a few issues regarding security. ![]() This lets the person with the master key access any lock in the group, while someone with a change key can open only his or her own lock.Many companies have owned their mechanical locking system for decades. In this lock design, the lowest pin is the same length in each lock in the group, but the master wafer varies in length. In both cases, there is a gap at the shear line and the key is able to turn. The change key might raise the pins so that the shear line is just above the top of the master wafer, while the master key might raise the pins so the shear line is at the bottom of the master wafer. When three pins are combined in a shaft, there are two ways to position the pins so they open the lock. This third pin is called a master wafer or spacer. In these locks, a few of the pin pairs are separated by a third pin. The change key will open only that specific lock, while the master key will open that lock and several others in a group. Some locks are designed to work with two different keys. The right combination of pins lines up perfectly with the notches in the key. The correct key will push each pin pair up just enough so that the point where the two pins come together lines up perfectly with the space where the cylinder and the housing come together - this point is called the shear line. The incorrect key will push the pins so that most of the top pins are still partly in the plug and partly in the housing. When you insert a key, the series of notches in the key push the pin pairs up to different levels.
