1. A Short History of Hotel Door Locks
The past of hotel security has dramatically evolved throughout the last century.
(1) Mechanical Beginnings
Early hotels employed only mechanical key-and-lock systems. Each room had a special key, typically large and cumbersome. Even though dependable, these locks were not secure—keys could be copied, and lost keys meant replacing the entire cylinder.
(2) Magnetic Stripe Cards
1970s introduced the revolutionary magnetic stripe card system. Guests were given a small plastic card with room details, which could be rapidly reprogrammed. Magnetic locks were convenient to manage keys but were prone to wear and demagnetization.
(3) RFID and Smart Access
By the early 2000s and late 1990s, there was radio-frequency identification (RFID). Contactless access, toughness, and additional encryption were offered by RFID cards. Today, mobile-based and IoT-integrated smart locks are the latest chapter, making it possible for guests to use smartphones or wearable devices as keys.
2. Types of Hotel Door Lock
Modern hotels are presented with an incredible range of door lock styles, from security to convenience and cost. Below is an in-depth description of the main hotel door locks that exist today, from the vintage hardware to the latest smart technology.
1) Mechanical Key Locks
These are the old-fashioned locks most people think of when they hear “hotel rooms.”.
