1. Hotel door lock type

There are four types of hotel door locks.

Hotel Door Lock

1) Keypad Door Lock

Many hotels use keypad door locks as a security measure. This type of lock utilizes a keypad (or combination of buttons) to enter a password for unlocking, making it easy to operate and convenient for users. Keypad locks eliminate the need for physical keys or key cards and allow guests to unlock with a unique password.

The electronic keypad lock can store over ten thousand passwords, and the combinations can be changed at will. It can also be equipped with an alarm system. It is easy to access, offers flexible code management, and provides higher security.

2) Digital Key Door Lock

Digital key door locks, also known as smartphone key locks, allow hotel guests to use their mobile phones as digital keys to access their rooms. Guests no longer need traditional physical keys or keycards.

Instead, they use a special hotel application to remotely control the guest room door lock. With smart technology, mobile key locks are becoming increasingly popular in the hotel industry. They provide guests with a modern seamless check-in experience and streamline check-in and check-out processes, improving hotel efficiency.

3) Biotech Door Lock

There are various types of biometric access in daily life, such as facial recognition, fingerprint recognition, vein recognition, iris recognition, voice recognition, and more. As a result of their high costs and maintenance expenses, they are rarely used in the hotel industry.

But there are two lock types of biotech door locks that are mostly used in hotels, fingerprint identification, and facial identification. Biometric door locks use unique biological features to grant access permissions. When checking in, you only need to register your personal identification information, such as fingerprints.

Then, you can unlock your commercial door lock with your fingerprint directly. Keyless access, no worries about lost keys, convenience, and security.

4) Key Card Door Lock

Key card door locks use various types of cards, including magnetic cards, IC cards, RFID cards, etc. They serve as password carriers and control the electronic hotel door lock by using corresponding card readers. This type of door lock is the most widely used electronic lock system in the hospitality industry. There are mainly two types: RFID hotel door locks and magnetic card hotel door locks.

RFID Hotel Door Locks: RFID card smart locks are still the primary electronic locks promoted in the hotel lock market. These locks rely on radio frequency identification technology and operate by using programmed key cards or key fobs that allow access to specific rooms. The RFID card has a built-in chip that is sealed and highly resistant to tampering, providing advanced identification technology.

Magnetic Hotel Door Locks: Magnetic cards are a kind of unlocking key, and they are similar to bank cards or credit cards. After the magnetic card is magnetized, it retains the same magnetic properties as the changing current and records the information sent by the current. The door lock reader verifies access permissions by identifying this information.

Magnetic cards are cost-effective and easy to read and write, but they are also prone to wear and demagnetization. They were the earliest smart cards used in hotel room locks, and even now, some small hotels still use them, although they are on the verge of being phased out.

2. Hotel access control system

Hotel access control machines are generally installed at the hotel entrance or the first door leading to the interior of the building. They are mainly used to control access within the building and enhance overall security.

Hotel access control systems typically offer various access methods, including card swiping, facial recognition, fingerprint scanning, password input, and mobile access. The specific methods available depend on the type and model of your machine.

3. Additional locking mechanisms

Additional locking mechanisms for hotel room doors are usually installed on the interior side of the door, allowing partial opening. They are designed to provide an extra layer of security for guests. Common additional locking mechanisms found in hotels include:

Hotel Chain Locks: Hotel chain locks consist of a chain attached to the door frame and a small sliding plate or rod connected to the door. When closed, the chain extends from the door frame, allowing partial opening while still providing security. This feature enables guests to communicate or verify identities with individuals outside the room before fully opening the door.

Hotel Security Latch: A hotel security latch is a lock installed on the interior side of the door, typically composed of a sliding metal rod or bolt that extends from the door into a strike plate or keeper on the door frame. The security latch provides an additional barrier to prevent unauthorized entry. It can be engaged or disengaged from inside the room using a lever or knob.

Hotel “U” Bar Lock: The hotel “U” bar lock is another common type of additional locking device found in hotel rooms. It is a “U”-shaped metal bar attached to the door frame and extends through the door when engaged. The “U” bar lock provides extra security by preventing forceful opening. It is usually manually operated and can be swung to the side or removed when not in use.
