A reliable door lock is a guarantee of the security of an apartment, house, office and other premises.

Locks installed by a qualified specialist will serve you without problems for a long time. The cost of replacing a faulty lock consists of several parameters:


When a quick replacement of locks is required, many do not want to spend time and money on contacting a specialist. Of course, you can attempt to change a faulty lock on your own. However, in such a case, the results are not guaranteed. The procedure for replacing locks consists of two stages – dismantling the old lock and installing a new device. Work on locks replacement can be complicated by the fact that the holes in the door are not identical to the new device, and so the door needs rework. In most cases, it is not possible to accomplish the replacement of a lock without damage with the help of improvised means. Many modern door models have a metal insert inside the case that prevents the opening of the locks using brute force. The metal insert can become a serious hindrance when drilling the new holes for the installation of the lock.  As a result, amateur work can result in damage to the house that entails the need for costly repairs. Professional-grade tools are also required to change the locking mechanism of a door. The lack of proper tools and practical skills can be the reason for the poor quality of lock replacement, leaving the house vulnerable to security threats. Residents are likely to have problems with opening / closing the lock. The locks can require frequent repairs due to improper installation. It is better not to risk the security of your house and entrust the installation of a new locking mechanism to a qualified locksmith. We have all the necessary knowledge and experience to complete the work on lock replacement quickly and efficiently without the slightest damage to the door structure.

When might you need a lock installation service?

  • Lock replacement is needed when moving to a new apartment or changing tenants;
  • If the existing device is out of order, it should be replaced or repaired for security reasons;
  • You may need to install an additional lock in order to increase the security of the premises;
  • Mechanism replacement may also be required after burglars try to break it.

Can the installation work be completed without turning to a professional?

The process of installing the locking mechanism consists of several steps. First of all, markings must be made on the structure at the place of installation of a replacement device. Then, holes for the fasteners are drilled according to the markings. All that remains to be done is to mount the lock in the structure and fix the striker. However, despite the apparent ease of the task, a number of difficulties can arise over the course of work:

  • The choice of replacement mechanisms can be a challenge due to the extensive number of available models on the market. The selection of locks should be based on the type of structure and security requirements for a particular property. Only a professional locksmith can competently choose a replacement device for installation;
  • For quick and high-quality work, a set of tools is required, as well as knowledge in the field of the design and operation of mechanisms of various types. The task requires certain skills and experience;
  • The installation in modern structures can be complicated by the presence of a sheet of hard alloy placed inside the case for protecting the locking device from drilling. Therefore, the installation of a mechanism can become difficult at the stage of drilling the mounting holes.

If you want all the work on installing the locking mechanism to be done correctly, so it serves you for many years without any complaints, it is better to entrust the installation process to an experienced specialist. The process does not take much time, and the risk of poor-quality installation with damage to the mechanism and the structure is minimized. We’ll be happy to assist you in solving any lock related problems.

Who should be entrusted with the installation of a locking mechanism?

Installation is a service offered by many local companies and handymen. Choosing a company for the provision of replacement services pay attention to the following:

  • The period of time the company has been in the locksmith business. We advise against blindly chasing low prices because often a low price is offered by one-day companies, whose staff consists of unqualified employees that carry out work on replacing the locking mechanism improperly without providing a guarantee for the quality of products;
  • When turning to a private handyman for assistance, there is a risk of encountering criminal elements. Make sure to research and read reviews. There are many known cases when criminals have burglarized properties using key copies they have made under the disguise of locksmiths.
