The drop bolt lock (Fallriegelschloss) is the oldest known lock in human history. The lock contains pins, the so-called tumblers, which fall into holes in the bolt and thus block it. The drop bolt lock is opened with the help of a pronged key, whereby upon opening the lock, the prongs lift the individual tumblers and release the bolt. Drop bolt locks contain a varying number of pins or tumblers, which can be arranged at different intervals. From this, and from the distance of the tumblers to one another, the individual locking variation of the drop bolt lock is derived.<\/p>\n

History of the Drop bolt lock<\/h2>\n

In human history, the drop bolt lock was the first lock that had to be opened with an individual key. Today, the oldest found drop bolt lock is estimated to be around 2,800 years old. It was discovered in the territory of modern-day Iraq. Naturally, it was made of wood back then, and since wood is not a particularly stable material, intruders could easily bypass the locking mechanism of the drop bolt lock by simply destroying the lock. Some highly spiritual peoples of West Africa had a great idea to prevent this: they designed their drop bolt locks in the shape of gods. No matter how criminal someone may be \u2013 they will think twice before destroying a divine figure because they fear divine revenge.<\/p>\n

The Drop bolt lock Today<\/h2>\n

Today, drop bolt locks are hardly used anymore, especially in modern industrial countries, but they can still be found to this day in parts of Africa or even Turkey.<\/p>\n

Even though drop bolt locks can hardly be found in our regions anymore, since the cylinder lock and the bit key lock now offer much better and more secure alternatives, various service areas of the Amper Aufsperrdienst naturally also deal with the topic of drop bolt locks. Thus, in addition to replacing a drop bolt lock with a more modern locking mechanism, doors with drop bolt locks can of course also be opened if, for example, the associated key has been lost.<\/p>\n
