Once you’ve chosen a secure hotel, there are additional measures you can take to ensure your safety. For travelers who are concerned about the security of their hotel room doors, there are several steps and precautions they can take to enhance their safety:

  • Check the Door: Ensure that the door closes fully behind you. Sometimes, doors can stick or not close completely, leaving a potential vulnerability. Check for any signs of tampering around the lock or the door frame.
  • Use the Deadbolt and Security Chain: Always engage the deadbolt and security chain when in the room. These provide an additional layer of security beyond the electronic lock.
  • Use a Portable Door Lock or Travel Lock: These are small devices you can carry with you and install on your hotel room door to provide an additional layer of security. They can prevent the door from being opened from the outside, even with a key.
  • Door Stop Alarm: These are portable devices that you can place at the base of the door. If someone tries to open the door, the device will prevent it from opening fully and will emit a loud alarm. This is especially useful for rooms lacking a deadbolt or security chain.
  • Do Not Disturb Sign: Even when you’re out, consider leaving the “Do Not Disturb” sign on the door. This can deter potential intruders.
  • Avoid Ground Floor Rooms: If possible, request a room on a higher floor. Ground-floor rooms are more accessible and might be more vulnerable to break-ins.
  • Keep a Light On When you leave the room, keep a light or the TV on. This gives the impression that someone is in the room.
  • Be Cautious with Keycards: Don’t leave your keycard out in the open, like on a restaurant table, where it can be easily cloned or stolen. If you lose your keycard, inform the hotel immediately and get a replacement.
  • Stay Alert: Be wary of unsolicited knocks or calls claiming to be hotel staff. If in doubt, call the front desk to verify.
  • Safe Usage: If your room has a safe, use it to store valuables, important documents, and electronics when you’re not in the room.
  • Secure Sliding Doors and Windows: If your room has a balcony with a sliding door or accessible windows, ensure they are locked. As an added precaution, you can also use a rod or bar to block the sliding track.

In conclusion, while the threat of hotel door lock hacks is real, travelers can significantly reduce their risk by being informed and vigilant. By choosing the right hotel and practicing personal safety measures, one can ensure a secure and enjoyable travel experience.
