When hotels tried to replace only part of the system, they quickly discovered that Cerraduras de puertas de hotel, key cards, and encoders from different brands are not compatible at all.
In this article, YonAnn explains why sistemas de cerraduras de hotel are not universal, what risks are involved, and how to safely replace your old system with a reliable new solution.

Why RFID Hotel Lock Systems Are Not Compatible with Each Other
Sistema de bloqueo de hotel
A hotel lock system is not just a physical lock — it’s a complete ecosystem that includes the lock hardware, software de gestión, key cards, encoder (card writer), y energy-saving switch. Each brand develops its own encryption and communication protocol, meaning different systems cannot recognize or communicate with each other.
1.1 Different Communication Protocols
Every lock manufacturer creates its own proprietary software-to-lock communication protocol. That protocol defines how authorization data is transmitted. As a result, software from Brand A cannot operate locks from Brand B, even if the locks look identical.
1.2 Unique Key Card Encryption
Most hotel locks use RFID cards such as MIFARE, TEMIC, or ID cards, but the encryption keys and data structures are brand-specific. Even if two cards look the same, their encrypted data is completely different. Therefore, a card from one brand will not open another brand’s lock.
1.3 Encoders Are Not Interchangeable
The card encoder (also called a card issuer or writer) is designed to work with its own software and encryption logic. If you try to use another brand’s encoder, the system will reject it or create invalid cards. This is why you cannot replace just the encoder or the card and expect it to work.
1.4 Security Reasons
Hotel locks handle guest privacy and safety — they must be secure and closed systems. Allowing “universal compatibility” would make it easier for unauthorized access or card duplication. So in fact, non-compatibility is a built-in security protection.

What If Your Original Hotel Lock Supplier Can’t Be Reached?
Many hotels are now facing this problem: their original supplier has disappeared or stopped providing software and hardware support.
As a result, they experience:
-
Software cannot be activated or downloaded
-
Key cards can’t be reissued or replaced
-
Encoder is unavailable or incompatible
-
Locks stop working with newer systems
-
Lost access to technical support
In such cases, there is no “universal fix”. Because different systems are encrypted and closed, you cannot mix parts from different suppliers. The only reliable solution is to replace the complete hotel lock system from a single brand.
