Since the early days of modern civilization, humans have had a sense of security to protect valuable things such as property. House security is the first step for mankind to guard the safety of their property. Door locks and keys have been an important part of human civilization for centuries. As human civilization has progressed, the types of door locks have evolved and upgraded.

The oldest prototype of door locks known to mankind dates back to about 2,700 years ago and was discovered in the ruins of an ancient Egyptian palace. The Egyptian wooden pin lock, consisted of a bolt, a door fixture or attachment, and a key.

The Romans, on the other hand, used Egyptian technology as a benchmark and developed protective locks with projections inside, using iron instead of wood.
