How to choose among the large assortment of locks suitable for you in price and quality? There are a lot of manufacturers offering quality goods, so choosing a lock is much more difficult than a door.
Today on the market there is a large assortment of similar products from brands such as Cisa, Mottura, Chubb, Medeco, etc. English and American options are a little expensive, but Italian Cisa locks combine high quality and affordable price. This brand offers a huge range of products - from mounted models to electromechanical.
The Italian locks Cisa, or "Chiza", are about thirty thousand different types of devices for locking doors. There is plenty to choose from, but in order not to be mistaken, you should study the main types of products of this manufacturer.
Benefits
Cisa locks are available for various purposes, designs and sizes. They can be installed on armored doors, wooden, aluminum, street gates, etc. The most important properties of such locking devices are quality and reliability. Such a product should not only close and open your door well and be a protection against breaking, but also serve properly and for a long time. All these qualities are possessed by Cisa locks. When installed correctly, they become reliable protection for any room.
Kinds
Locks "Chiza" are overhead, mortise and padlocks. In terms of secrecy, they are divided into lever, cylinder, and by the principle of closing - into mechanical, electromechanical and electromagnetic. Locks of the latter type are more suitable for installation on the entrance doors to the entrance of an apartment building, but for apartments this is not the right option. In particular, such devices have a significant drawback: in the absence of electricity, they simply open, and the room remains unprotected.
Another type of locks manufactured by Chiza is multifunctional. They combine a cylindrical and leveling system. These locks belong to a series 57 and are the most demanded products of this brand. The combination of two locking systems greatly improves their quality and reliability.
Range
Among the many models for different doors and needs, Cisa mortise locks can be noted: 56.525.48 with a cylinder mechanism, lever locks 57.525.28 and a very simple mortise lock - 5.110-60 with one flat crossbar. The brand also produces overhead electromechanical options 11.630.60.2 or 11.931.60.3, which are opened with a key and a button, and mortise - 12.011.60. These models are very convenient and are not afraid of power outages, as they open mechanically with a conventional key. The power needed for their operation can be constant (12V and 24V) or alternating 24V (at 3.1A).
Lock Replacement
There are situations when these devices fail and cannot be repaired. Then replacement of locks Cisa is required. It should be remembered that the design of these products eliminates their hacking. If a broken lock needs to be replaced, and you no longer need it, you can use tools such as a drill or angle grinder to dismantle it. However, it is better to invite a specialist. He will be able to remove the lock with minimal damage, since, perhaps, only the larva has failed. In this case, it is necessary to carefully measure all the seats, the size and type of fittings, since knowledge of these parameters will help to establish a new model efficiently and without much difficulty.
How to recode a lock
For the convenience of replacing the devices from Chiz, their developers invented a system that helps in a situation where keys are lost. In the cylinder lock, the larva changes, and in the lever lock, the possibility of transcoding is provided. It is enough to change the key to a new one in the form of the letter "G", which is sold complete with the device. Each of them is accompanied by special instructions. Castle Cisa with its help is recoded in a couple of minutes.
In short, this process looks like this: a valid key is inserted and the lock is completely closed. To do this, the crossbars are fully extended. Then a āGā -key is used to encode. It is inserted into the end hole and rotated counterclockwise towards the inside until it clicks and is removed. Then remove the old key from the keyhole, insert a new one and open the lock. All! Now you can safely use the new set of keys.
How to install Cisa Castle
When buying such a device, it is imperative to check that the kit contains instructions containing information on the rules for its installation and operation.
Cisa locks must be installed by a specialist with experience. All performance, durability and reliability of the device during operation will depend on who installed it and how. It should be remembered that the installation of Cisa multifunctional locks by an amateur is successful only in one case out of 10. Is it worth it to waste time and spoil your door?
Repair of locks Cisa
No device is insured against breakage. The reasons are different: the door is skewed, the hardware broke, the device was damaged as a result of careless handling, finally, it just stopped working for unknown reasons, etc. To make the lock work, it is enough to do preventive maintenance or adjust it. Buying a new device or paying for its installation is not cheap. Therefore, the best option is to repair the castle, entrusting this task to a professional.
Sometimes it is possible to fix the malfunction by replacing the grub of the device. This is not difficult to do with little experience and the availability of the necessary tool. To do this, you need to know its size, type of lock and cylinder and buy exactly the same. You can simply remove the larva and take it with you to the store. Then the seller will not be difficult to pick up the same model. As a rule, the larva is fastened with just one screw. It is located on the front of the castle, and it is easy to work with. It is enough to completely unscrew the screw. Then you should remove the larva, install a new one and, turning the key in different directions, check the correctness of the installation of this part. Having found the desired position in which the lock is easily unlocked, you should fix the device with a screw, tightening it until it stops.
disadvantages
Like any other product, Cisa door locking devices are not ideal. Mostly flaws are manifested by improper installation or operation. For example, they are afraid of even the weakest load. This can lead to the fact that they can easily jam with a small resistance to the crossbar, even at the time of installation. In this case, you have to cut the door along with the lock. In addition, in new models the reason for their jamming often becomes an additional system of protection against hacking.
