Code lock for doors: function, advantages & tips

PIN codes play a role in many areas of everyday life. Code locks for front doors, garage doors and other entrances are also becoming increasingly popular. This article shows how a code lock works, what advantages it offers and what you should consider when using it.

What is a code lock, and how does it work?

A code lock is exactly what you would expect from the name:a lock that can be opened by means of codes. A conventional key for the mechanical opening of the door is no longer required. Rather, there is a so-called code button on the respective door – as a kind of keyboard. Authorized persons can use this to enter the code and the door opens. Usually, such codes are four or six digits.

The way it works is similar to many other systems that are operated with a code: be it the PIN code to unlock the smartphone or the code used to authorize payments with the bank card.

Even though the function of code locks is quite simple, there are different types. Some work mechanically, others digitally, and still others by radio.

• Mechanical code lock: The digits are set manually and are not entered directly on the code button. This functionality is also known from safes or bicycle locks, for example. You then have to turn or otherwise operate a component to open the lock.
• Digital code lock: In the digital version, the digits are simply entered on the code button. Sometimes you have to press a confirmation button afterward. With some code locks, the lock opens immediately after entering the last digit.
• Code lock with radio: In some locks, users can enter the code by radio. Many garage doors work this way. You therefore do not have to leave the vehicle to drive on the driveway.

The code lock and its diverse areas of application

Code locks are considered practical and versatile. Therefore, they are used in many different areas. Some install a code lock on the front door. This means that not every family member has to carry a key with them, but only know the access code. However, code locks are particularly popular in apartment buildings where several parties go through the front door.

A code lock is often also used outdoors – for example, in garage doors or garden sheds. This means that all locks are optimally secured.

However, code locks are not only used in the private sector. Rather, many companies also use them. In the commercial sector, code locks are suitable for securing a site, for example. Or the company building is securely protected from unauthorized access.

In shopping malls, for example, there are often lockers with code locks. And these or similar functions also prove helpful in schools, universities or public institutions.

Code locks are also used in the hospitality industry. Hotels and holiday apartments can be optimally secured with this type of locks. This means that each guest receives an individual code, so that no loss of keys is possible, but access is possible at any time.

Benefits of Code Locks

Code locks are used in the private and business sector for many reasons. They offer a number of great benefits, which makes their use increasingly popular. We have summarized the 4 most important advantages of code locks.

1. No problem with losing keys

If a key is lost, it is not only annoying because you have locked yourself out. It also poses a significant security risk –after all, someone could find the key and gain unauthorized access.

This does not matter with a code lock. There is no physical key to lose. Only the code can be forgotten. However, the person who manages the castle can help out quickly. So it's not a real problem.

2. Easy to manage

Code locks are easy to manage. Building owners can change the code at any time via central software. This is not only useful if you forget the code. Even if, for example, you have a visitor, and he knows the code, but then leaves again, it is advisable to assign a new code. The same goes for neighbors who took care of the house while you were on vacation. And this approach is also often very much appreciated for holiday apartments.

3. Full control thanks to code lock

A code lock cannot be opened with just a single code. It is also possible to  give each user their own code. In this way, you always have an overview of who entered the building and when. This is especially useful when several people come in and out. But even if you want to couple the access system with working time recording, this function is extremely practical.

4. Maximum comfort

Users don't need a physical key, so they can't forget or lose it. Rather, entering buildings will be even easier and more comfortable. If you already have a full bunch of keys, you don't need another key, at least for this one lock.

Maximum security through the combination of code lock and other locking media

If you are thinking about retrofitting a code lock to the front door, you should also pay attention to the aspect of security. In particular, the combination of code lock and other locking media can enable maximum security. There  are a number of options available with providers such as BlueID. Building owners can achieve flexible solutions and choose an access system that  is individually tailored to their needs.

For example, the combination of a code lock with an additional locking cylinder for a mechanical key is recommended. Alternatively, a digital identification medium is also suitable. This means that users will only be granted access to the building if they have entered the correct code and activated the additional locking medium.

In addition, it is possible to enable both locking systems, but users are free to choose how to open the lock. For example, there are locking systems that are normally opened with a PIN code,  but can be operated manually with a conventional key in an emergency. Here, it depends heavily on the individual requirements and needs.

In any case, when using a code lock, it is important not to give the code to unauthorized and unknown persons. Rather, it is one of the pieces of information that must be particularly protected. This applies to both the private and commercial sectors.

Result

Code locks are used in a variety of ways and have a lot of advantages. To  further increase security, they can be easily combined with other locking media. At BlueID, you will receive tailor-made solutions that are a perfect fit for your property. You can benefit from the advantages of a code lock.
