Key locks, electronic locks, multi-point locks: advantages and disadvantages
The choice of lock is crucial to the security of your home or business premises. There are a wide variety of locks on the market today, ranging from traditional keyed models to electronic lock systems and multi-point locks. Each type of lock offers different levels of security, comfort and functionality. In this section, we'll explore in detail the different types of lock, their advantages and disadvantages, to help you make an informed choice based on your specific needs.
1. Key locks: the traditional solution
The key locks are the most common and probably the oldest. They work by means of a cylinder into which you insert a key to operate the locking mechanism. These locks are available in a wide range of models, from simple single-point locks at multipoint locks.
Advantages of key locks
- Ease of use Key locks are simple to use and install. They require no special skills to operate, making them an ideal option for entrance doors or gates.
- Affordable cost In general, key locks are more affordable than other locking systems, especially basic models. Their price varies between 50 and 200 euros, depending on the brand and level of security.
- Easy to maintain Key locks are easy to maintain. A little lubricant is all it takes to keep the mechanism in good condition for many years.
Disadvantages of key locks
- Limited safety (standard models) Standard key locks offer a relatively low level of security, especially single cylinder or single point locks. These models are often vulnerable to burglary techniques such as hooking, the bumping or the drilling.
- Risks associated with key loss One of the major disadvantages of key locks is the risk of keys being lost or stolen. In these situations, the lock can become vulnerable, and cylinder replacement is often necessary to avoid any risk of burglary.
2. Multipoint locks: enhanced security
The multipoint locks are the modern evolution of key locks. They also work with a key, but they lock the door in several places (usually 3 or 5 points), which considerably increases security. These locks are particularly recommended for entrance doors and armoured doors.
Advantages of multipoint locks
- Superior level of safety Multi-point locks are much more difficult to break into than single-point locks because of their multi-point locking mechanism. They lock the door at the top, bottom and centre, making it more difficult to break in. They are therefore highly recommended for front doors, especially in large cities like Paris, where the risk of burglary is higher.
- A2P approval : Many multipoint locks are A2P certified (an insurance-recognised safety standard), making it a wise choice for homes requiring extra protection.
- Resistance to burglary techniques Unlike single-point locks, multi-point locks offer greater resistance to burglary techniques such as drilling, picking or forcing. They are also often equipped with anti-drilling cylinders and anti-pinching.
Disadvantages of multipoint locks
- High cost : The price of a multi-point lock is higher than that of a standard lock.
- Complex installation : Installing a multi-point lock is more complex than installing a simple lock, which increases the cost of labour. It is therefore advisable to call in a qualified professional, like those of ASAP Serrurerie, to ensure correct and compliant installation.
3. Electronic and connected locks: modernity at the service of security
The electronic locks and connected locks are modern locking devices that do not require the use of a physical key to operate. They generally work with a code, card, smartphone or biometric fingerprint.
Advantages of electronic and connected locks
- Comfort and convenience : One of the main advantages of electronic locks is their practical. You no longer need to carry physical keys, which eliminates the risk of loss or theft. You can open the door with a code or a simple click on your smartphone.
- Remote control Some connected locks allow you to control access remotely via a mobile application. You can, for example, authorise access to a service provider or a member of your family, even if you're not on site.
- Enhanced security : Electronic locks offer high level of safety, including models with biometric recognition. These locks are difficult to break into or hack. What's more, some are equipped with alarm systems in case of attempted break-in.
- Access history : Connected locks offer the possibility of consulting a opening and closing history, This can be useful for finding out who has entered or left your home and at what time.
Disadvantages of electronic and connected locks
- High prices The cost of electronic locks is generally higher than that of mechanical locks. Prices vary according to model and functionality (biometrics, remote control, etc.).
- Dependence on electricity or connectivity Electronic locks require a power supply or Internet connection to work properly. If the system fails, you could find yourself locked out. It is therefore essential to have a back-up solution, such as a double mechanical system.
- Complexity of installation As with multipoint locks, the installation of an electronic lock is more complex and requires the intervention of a professional. What's more, these locks often require regular software updates to remain secure.
4. Code locks: a secure alternative
The code locks are operated by a numeric keypad on which you enter a code to unlock the door. This type of lock is particularly popular in blocks of flats, offices or premises requiring access control.
Advantages of code locks
- No physical key Like electronic locks, code locks do not require a physical key, so there are no problems with lost or stolen keys. They are therefore practical for places where several people need to have access (business premises, buildings, etc.).
- Simple access management You can easily change the access code if you need to, without having to replace the whole lock. This is particularly useful if a person with access is no longer authorised to enter (for example, after a change of tenant).
Disadvantages of code locks
- Relative safety Code locks offer a decent level of security, but they can be vulnerable if the code is mishandled or if an unauthorised person learns it. In addition, some cheap code locks may be less resistant to attempted break-ins.
- Keyboard wear Over time, the keys on the keypad can wear down, which can make some locks more vulnerable. For example, wear marks on certain keys can give clues to the code used.
5. Biometric locks: fingerprint security
The biometric locks are electronic locks that use a fingerprint or other physical characteristics (such as the retina) to unlock the door. These locks offer a very high level of security and are often used in environments requiring maximum protection (offices, sensitive premises, luxury homes, etc.).
Advantages of biometric locks
- Maximum safety Biometric locks offer one of the highest levels of security, as they use unique and inimitable features (such as a fingerprint) to unlock the door. They are very difficult to hack or bypass.
- Ease of use Opening the door with a fingerprint is simple, quick and convenient. There's no risk of losing a key or forgetting a code.
Disadvantages of biometric locks
- High prices Biometric locks are among the most expensive on the market.
- Dependence on technology As with electronic locks, biometric locks depend on technology and require a power source. If the system breaks down, it is essential to have a back-up means of gaining entry.
