If your grand master key cards for the Kaba door lock system are not functioning and you can’t immediately contact the company for support, you may attempt a reset using the Kaba 780 FDU machine. Please proceed cautiously and ensure you are authorized to perform such actions, as incorrect handling can lead to further issues or security breaches.

Here’s a generalized procedure you might follow:

1. Access the Kaba 780 FDU: Navigate to the device in your hotel that is used for programming and managing the locks and keys.
2. Authenticate Yourself: Make sure you log in or authenticate yourself using a manager’s or administrator’s card or the relevant credentials.
3. Locate the Grand Master Key Settings: Within the system’s menu, navigate to the section where you can manage or program master keys.
4. Select the Key to Reset: If you have multiple master keys, select the correct one you wish to reset.
5. Reprogram the Key: Follow the system prompts to reprogram the key. This usually involves encoding a new key card with grand master key permissions. Ensure you’re using the correct authorization codes and programming settings.
6. Test the New Key: Before deploying the new grand master key, test it on several locks to ensure it works correctly.
7. Securely Store the Old Key: If the old grand master key is a physical card, ensure it’s securely stored or properly disposed of to prevent unauthorized use.
8. Record the Changes: Document the reprogramming for your security records, noting the date, the person responsible, and any other relevant details.
9. Monitor the Lock System: After resetting the grand master keys, keep a close eye on the system to ensure no further issues.

If you’re not familiar with the Kaba 780 FDU machine, it’s generally advisable to wait and contact Kaba’s customer support for proper guidance to avoid potentially compromising your hotel’s security system. Remember, master keys provide extensive access to your property, and managing them with the utmost security is paramount.

Also, please note maybe the validity period of your grand master key card has expired. You may need to extend the use time of this grand master key card instead of resetting it.

To extend or reprogram the expiration date for an authorized master key using a Kaba key encoding system, you’ll need access to the Kaba Front Desk Unit (FDU) device. Here’s a general guide on how to do this:

1. Access the Kaba System: Swipe a GMA-authorized keycard For Contactless 790 and Confidant RFID, and present a valid FDU Authorization Keycard to the external Contactless Encoder. (Note: You cannot use FDA Keycard or PIN to access this Function)
2. Locate the Master Key Settings: Navigate through the system to find the section where you can manage master keys.
   1. Press 6 to select the “Staff Keycard” menu.
   2. Press 5 to select the “Grand Master” menu.
3. Adjust the Expiration Date: Press the right > arrow to allow access to available Time Zones; change the expiration date to the new desired date. Once Time Zones are set, press the enter button. Ensure that the new expiration date complies with your hotel’s security policies and the specific needs of the key holder.
4. Reprogram the Key: After setting the new expiration date, you must reprogram the physical key card. Insert and swipe a blank guest keycard and present the card to the Contactless Encoder (for 790 / Contactless RFID locks).
5. Confirm the Changes: Some systems might allow you to confirm the changes on the screen before finalizing the reprogramming. Ensure that all the details are correct.
6. Test the Key: Before redeploying the master key, test it on a few doors to ensure it works correctly with the new expiration date.
7. Record the Changes: Log the changes in your hotel’s security records, noting the key’s number, the new expiration date, and the person responsible for the changes. Proper documentation is crucial for maintaining security and accountability.
8. Redistribute the Key: Hand the master key back to the authorized holder, informing them of the new expiration date and any other relevant changes.
