In case of a malfunction in the lock, we have incorporated a "fail-safe design" that functions on the safe side! This prevents troubles that would cause the door to become inoperable!
● The lock is a consumable item. Even with careful use and proper maintenance, there are limits to the performance of the product. Using the product beyond its capabilities can lead to malfunctions or accidents. In the unfortunate event that the lock breaks and you become trapped indoors... ● TXS lock's fail-safe mechanism When excessive impact is applied to the lever handle, or when excessive rotational torque causes metal fatigue, or if damage occurs due to normal use (repeated light loads: aging deterioration) leading to component wear, the latch bolt will remain retracted inside the lock (activating the fail-safe), preventing issues such as the door becoming unable to open.
