Emergency Key Card Supply Resolved in 24 Hours

Overview

Industry: Hospitality – 100+ room Hotel
Scenario: Emergency key card shortage – Assa Abloy lock system – MIFARE Ultralight AES Chip
Challenge: Supplier delay with no remaining stock during peak occupancy period
Solution: Next-day supply and direct delivery
Outcome: Full resolution within 24 hours with no disruption to operations

The Situation

A hotel contacted RFID Hotel on a Thursday morning after being informed of a delay from their existing supplier. As a result, they were at risk of running out of room key cards ahead of a busy weekend check-in period. For hotels, key cards are critical to daily operations. Without them, guests cannot access rooms, front desk teams face increased pressure, and service levels can quickly decline.

The Challenge

The hotel needed a fast and reliable solution to avoid running out of key cards entirely before the weekend.

Key risks included:

Guests being unable to access their rooms
Long queues and delays at the front desk
Increased pressure on staff during peak check-in periods
Negative impact on the guest experience

With limited time available before the weekend, the hotel required replacement stock quickly and with complete confidence in compatibility.

The Solution

RFID Hotel assessed the requirement immediately and confirmed the correct key card specification, ensuring full compatibility with the hotel’s ASSA ABLOY (VingCard) system using MIFARE Ultralight AES technology.

We were able to:

Identify and prepare the correct key card type
Supply genuine compatible AES key cards from available stock
Arrange next-working-day delivery ahead of the weekend

The order was placed before 2pm on Thursday and dispatched the same day for Friday delivery.

Implementation

The replacement cards were prepared, verified for compatibility, and shipped immediately following order confirmation. The cards arrived on Friday ready for immediate use, requiring no additional setup or changes to the hotel’s existing system.

Because the correct specification was confirmed upfront, the hotel was able to continue normal operations without disruption ahead of a busy weekend period.

The Result

The hotel received replacement key cards before stock was fully depleted, allowing operations to continue smoothly without interruption.

Key outcomes:

Genuine AES replacement key cards delivered before the weekend
No interruption to guest access
Front desk operations continued as normal
Urgent stock issue resolved with next-day delivery

The hotel was able to manage Friday evening arrivals and weekend check-ins without operational impact.

Customer Feedback

“We were incredibly impressed by how quickly Sonny Fox responded. What could have become a major issue for our guests was resolved before the weekend. The support and urgency shown by the team made all the difference.”

What Made This Project Unique

This project required a rapid understanding of compatibility requirements and immediate action to prevent operational disruption before a busy weekend period.

Because the system used MIFARE Ultralight AES technology, selecting the correct genuine card type and ensuring accurate compatibility was critical. Having available stock and hospitality-specific RFID knowledge allowed the issue to be resolved quickly and reliably.

What This Means for Other Hotels

This case highlights how important it is for hotels to have access to reliable RFID key card supply, particularly during busy operational periods.

Hotels can reduce risk by:

Maintaining backup stock
Confirming compatibility in advance
Working with suppliers that understand hospitality RFID systems
Choosing suppliers with available stock and fast dispatch capability

Key Takeaways

Fast access to genuine compatible key cards can prevent operational disruption
Stock availability and responsiveness are critical within hospitality
Correct specification is essential when using AES RFID technology
Reliable RFID supply partners help protect both guest experience and front desk operations

What should I do if my key card supplier lets me down last minute?
If your current supplier cannot deliver on time, the priority is finding a supplier that can confirm compatibility immediately and provide stock without delay. In urgent situations, having access to pre-approved, in-stock cards that match your system can prevent disruption and keep operations running.
Why are my replacement key cards not working with my ASSA ABLOY system?
This is usually due to incorrect chip type or configuration. ASSA ABLOY systems, particularly newer setups, often require MIFARE Ultralight AES. Ensuring the correct specification is confirmed before supply avoids cards failing at the door or needing re-encoding.
How can I avoid delays when ordering replacement key cards?
Delays often happen when compatibility needs to be rechecked or cards are made to order. Using a supplier that holds stock of commonly used chip types and can quickly verify your system setup helps reduce lead times and ensures faster turnaround when it matters.
How do I make sure replacement cards work immediately on arrival?

Cards should be supplied with the correct chip type and verified against your system requirements before dispatch. This ensures they can be encoded and used straight away, avoiding additional setup or disruption at the front desk.
