A stuck lock cylinder is one of the most common and frustrating situations faced by door owners. The mechanism stops turning or works with noticeable resistance, and attempts to “force” the key may lead to serious damage. Let’s look at why this happens and what actions can help solve the problem safely.
Most often, the cylinder gets stuck due to contamination inside the mechanism. Dust, fine metal shavings from the key, and old dried lubricant interfere with the free movement of the pins. In such cases, careful cleaning and the use of a special lock lubricant can help, but it’s important to avoid aggressive products and universal sprays.
Another common reason is wear of the key or the cylinder itself. If the key is deformed, chipped, or has worn-down teeth, it may jam inside the mechanism. Sometimes replacing the key is enough, but in cases of severe wear, the entire cylinder needs to be replaced.
A cylinder may also get stuck because of door misalignment. When the door sags even slightly, the lock begins to operate with increased force and may eventually jam completely. In this situation, hinge adjustment or reinstallation of the lock is required.
It’s important to remember that using force is the worst possible solution. Attempts to turn the key all the way or use a screwdriver or other objects can break the mechanism or snap the key inside the lock.
If the lock is completely stuck and gentle methods don’t help, it’s best to contact professionals who perform emergency lock opening. A technician will safely open the door without damaging the surface or hardware and will determine the exact cause of the jamming.
Regular maintenance, careful use of the lock, and timely replacement of worn parts help prevent such situations and extend the lifespan of the door mechanism.
