Mortise locks have been in use for centuries, with the earliest known example being found in the ruins of ancient Egypt. They are one of the oldest and most reliable types of locks and have been used to secure doors, windows, and other openings since the Middle Ages. While mortise locks are still in use today, their popularity has declined significantly in recent years.
Mortise locks are a type of lock that requires a hole to be cut into the door or frame in order for the lock to be fitted. The lock is then secured by two metal plates that are inserted into the hole and secured with screws. The plates are connected by a metal bar that is operated by a key. Mortise locks are usually very secure, as they require a key to open them and the metal plates make it difficult to pry them open.
The popularity of mortise locks began to decline in the 19th century, as new technologies such as the pin tumbler lock became available. The pin tumbler lock was much easier to install than a mortise lock and was also more secure, as the pins inside the lock made it difficult to pick. This led to the decline of mortise locks, as they were no longer seen as the most secure option.
In the 20th century, the popularity of mortise locks continued to decline as new technologies such as electronic locks became available. Electronic locks are much easier to install than mortise locks and also offer a higher level of security. Additionally, electronic locks are much more convenient, as they can be programmed to open with a code or a key card.
Today, mortise locks are still used in some applications, such as in historic buildings or in certain types of furniture. However, they are no longer seen as the most secure option and are usually only used in situations where a more traditional look is desired.
Overall, mortise locks have been in use for centuries, but their popularity has declined significantly in recent years due to the availability of new technologies such as the pin tumbler lock and electronic locks. While they are still used in some applications, they are no longer seen as the most secure option and are usually only used for their aesthetic appeal.
