[Solved] What Locks Do Hotels Use?

As far as I know, the most commonly used hotel lock system in hotels at present is the RFID hotel lock system.

RFID hotel lock system: RFID key cards for RFID hotel lock system contain a chip that communicates wirelessly with the reader when close to the lock's reader. Guests unlock the door by placing the card near the reader.

Advantages: More durable and more secure than magnetic stripe cards. The card is not easy to wear out.
Disadvantages: The initial cost is higher compared to the magnetic stripe system. Compatible RFID cards and readers are required.
Price: Due to the use of RFID technology, the price is slightly higher, but it is more secure and has a longer service life. The general price is between $40-80/card.
Application: Modern hotels prefer this card for increased security and guest convenience.

But please note that the RFID hotel lock system usually includes several important components: RFID hotel lock, RFID key card, RFID card encoder and RFID hotel lock system software. These components must be used together to form a complete and secure RFID hotel lock system

In my city, most hotels still use the older magnetic stripe card hotel locks

Magnetic stripe card locks: Guests receive a card with a magnetic stripe containing coded data. Guests swipe the card on the card reader on the lock to open the door.

Advantages: Economical to implement. Simple for guests to use.

Disadvantages: Cards may become demagnetized and need to be reissued. Magnetic stripes are easy to copy and have security vulnerabilities.

Price: Due to widespread use and simple technology, prices are usually very affordable. Prices are generally between 30-60$.unit.
Usage: Various hotels, from small, motels, economy to mid-range hotels.

But generally more traditional and older hotels use them.

I prefer Bluetooth mobile access locks for modern and newer hotels

Bluetooth mobile access locks connect to the guest's smartphone via Bluetooth. Guests receive a digital key through the hotel's mobile app and can unlock their room by simply placing their phone near the door or tapping a button in the app.

Pros:

• No need to use physical key cards, reducing plastic waste.
• Provides a seamless, contactless experience for guests.
• Convenient for guests who like to do everything with their phones.
• Encrypted digital keys offer high security.

Cons:

• Requires guests to have a smartphone with Bluetooth capabilities.
• Can be problematic if the guest's phone runs out of battery or has connectivity issues.
• Costs can be high.

Price: Higher upfront cost due to app integration and Bluetooth hardware. Prices are generally between 60-120$/unit.

Mainly used in upscale, tech-savvy hotels or hotels that offer a smart hotel experience, perfect for guests seeking modern conveniences and contactless options.

Of course, most B&B-style hotels currently also prefer to use this Bluetooth mobile access lock, mainly when there is no one to receive the B&B room, the Bluetooth key or password can be remotely sent to the guest via mobile phone.

Some hotels also use pin code locks as door locks for hotel rooms, but this type of lock is rare. I have only seen it in some hotels converted from family rooms in small cities.
If you don't have many guest rooms, you can also try using a pin code lock.

Pin code lock: Guests will be given a unique PIN code, which they can enter through a keypad installed on or near the door to enter.
Advantages: No physical card is required, which reduces the risk of card loss or demagnetization. The password can be easily changed without reissuing the card.
Disadvantages: Guests may forget their PIN code. The keypad will wear out over time and require maintenance.
Price: Usually the price is similar to RFID locks, depending on the brand and features. Some well-known brands generally cost 80-150$/unit.
Application: Usually used in small family hotels, or hotels that focus on self-service options.

If you don't have many rooms and want to save as much as possible, then mechanical key locks may be a better choice.
Traditional locks operate by inserting a mechanical key into the lock cylinder and turning it to unlock the door. These locks rely entirely on physical mechanisms and have no electronics.

Advantages: Simple and reliable, not dependent on power or electronic systems. Can serve as a backup for electronic systems in case of system failure. Easy to use for guests who are familiar with traditional keys.

Disadvantages: Less secure than electronic systems because keys can be easily lost, copied, or stolen. It is inconvenient for employees if multiple keys are required to enter the room.

Price: Usually lower because mechanical locks are cheap to install and maintain. The general price is around 10-30$/unit.

Mainly used in small budget hotels or as a backup option for large hotels with electronic systems.

Please note: The locks described above are mainly used on the outside of hotel room doors. If you want to provide better security for your hotel, locks for the inside of hotel room doors are still necessary. Such as portable hotel door lock, hotel door latch lock, hotel door bar lock, and hotel chain lock.

Portable Hotel Door Lock: This is a temporary lock that guests can fasten to the door from the inside. It is usually installed on the door's strike plate and adds an extra layer of security by preventing the door from being opened (even if someone has the key).
Pros: Easy to carry and install, giving guests peace of mind. Provides an extra layer of security beyond the standard door lock. Great for travelers who are concerned about safety issues in unfamiliar environments.
Cons: Can only be used when the guest is in the room.
Price: Usually inexpensive, ranging from $10 to $30.
Uses: Popular among solo travelers or those seeking extra security. Not permanently installed, but an additional security option that guests can choose to carry or not.

Hotel Door Bar Lock: A metal bar fixed to the door frame that swings horizontally across the door to lock the door from the inside. The bar prevents the door from being opened even if the main lock is released.
Pros: Sturdy and reliable, providing strong security. Easy to use and highly visible, deterring unauthorized entry.
Cons: Can only be used when guests are in the room. Takes up some space on the door and may not fit all types of doors.
Price: Usually affordable, around $15 to $50, depending on the material.
Uses: Commonly seen in hotels where security is a priority, providing additional protection for guests in the room.

Hotel Door Latch: A latch installed on the door and door frame that allows guests to lock from the inside. The latch prevents the door from opening completely, even if the main lock is unlocked.
Pros: Simple and effective, providing additional security. Guests can partially open the door to talk to someone or receive a package while maintaining a certain level of security.
Cons: Can wear out over time and requires maintenance or replacement. Does not provide adequate security like a door lock or chain lock.
Price: Usually inexpensive, around $10 to $30.
Uses: Common in mid-range and budget hotels, providing basic additional protection.

Hotel chain lock: Chain attached to door and door frame, allowing door to be opened slightly while still secured with chain. Chain can be used by guests from inside to prevent unauthorized entry.
Pros: Easy to use, allows guests to partially open door while preventing full entry. Provides basic additional security beyond main door lock.
Cons: Can be easily damaged or tampered with, limited security compared to other options like door locks. Chains may loosen over time and need to be replaced.
Price: Relatively inexpensive, usually between $5 and $20.
Uses: Common in older hotels, provides a traditional security option, but is generally considered less secure than modern alternatives like latches or door locks.

The locks used on the inside of hotel room doors can be chosen based on the needs and budget of your hotel.
