Is it a rim lock or mortise lock? Verify the bolt, strike, deadbolt, cylinder, and locking mechanism's measurements at all times. A door lock needs to be properly picked, regardless of whether you open it from the right or the left, by pushing or pulling. These are the best suggestions. (αλλαγη κλειδαριασ)
Disassemble the model you intend to replace (taking it with you when you purchase the new one is the most convenient option).
Using a meter, paper, and pencil, measure everything that can be measured and record the results.
When buying a new lock, pay attention to the door opening method and then evaluate the options available on the market.
If you are not too knowledgeable, you can efficiently identify the features of your lock by applying the following criteria in order:
To surface, either vertically or horizontally, depending on the case's proportions, or to embed (also known as mortise). Therefore, they are categorized as vertical when their height exceeds their depth, and as horizontal when their depth exceeds their height.
The dimensions of the box, the bulb or cylinder, the front, the latches, the square, and the distance between axes.
The locking system, the cylinder or the mechanism.
The single-point or multipoint.
The opening direction to the right or left by pulling or pushing to the right or left.
The locking system can be:
There is an elongated cavity inside containing a kind of cam that is activated when the key is inserted into the cylinder. When the key is not inserted, the internal pins drop down, preventing another type of key from being inserted and forced. It is important to determine its shape, length, security level, and number of openings. The key is usually flat, with one or two carved profiles, or with holes.
This is the traditional system. A key activates the opening or closing system, in which case it is integrated into the lock. The key is usually heavy, called a groove or a pallet key, and this type of lock is for interior use.
Increasingly developed to improve security, they can be card-based, badge-based, or button-based (on the inside). Some include a remote opening function, controlled from a mobile phone.
A lock cylinder is usually reduced by 30-30 mm (measured from the center of the cylinder to each of the two ends). Classic double-entry cylinders can come in other sizes: 30-40; 30-50; 50-50, etc. In these cases, they are given different names, such as centered, asymmetrical, or half-cylinder.
The security level varies: anti-picking, anti-drill, anti-key copying, anti-breaking; and it complies with the A2P standard.
In addition to the security level, several other variants stand out:
Removable or Detachable Cylinder – Allows it to be opened from the outside. Its main advantage is that in case of loss, the entire lock does not need to be changed, just the cylinder.
Half Cylinder – Accessed with a key from the outside and can be locked from the inside. It is widely used, for example, for garage doors.
Push-Button Cylinder – Accessed with a key from the outside, and the inside can be locked with a button. This is the most commonly used type, for example, in public restrooms. https://okleidaras.com/ilektronikoi-kylindroi/
