How to Fix Keylok Dongle Macro Problems in Excel
Question details
The user needs to resolve an issue where Microsoft Excel rejects or fails to execute macro files associated with software protected by a Keylok hardware dongle.

- Product
- Microsoft Excel
- Device & OS
- Windows
- Scenario
- Opening and running third-party macro files protected by a Keylok hardware dongle in Excel.
- Observed behavior
- Excel blocks or does not accept the macro files, preventing the Keylok-protected software integration from functioning correctly.
Ensure your Keylok hardware dongle is securely plugged into a working USB port on your computer and that you have administrator privileges to install drivers or change file properties.
Update Keylok Drivers and Unblock Macro Files
Ensure the hardware dongle is properly recognized by Windows and remove any system security blocks on downloaded macro files.
Windows often blocks macro files copied from another computer or downloaded from the internet for security reasons. Unblocking them allows Excel to process the macros.
Install the latest Keylok driver and application version provided directly by your third-party software vendor.
Open Windows Device Manager to confirm the Keylok dongle is detected successfully and has no yellow warning triangles.
Open Windows File Explorer, locate the problematic macro file, right-click it, and select 'Properties'.
At the bottom of the 'General' tab, check the 'Unblock' box if it is visible, then click 'Apply' and 'OK'.

Adjust Excel Trust Center and Macro Security Settings
Modify Excel's security settings to allow the specific macros provided by the Keylok software vendor to execute without being blocked by Protected View.
Verify Office Bitness Compatibility
Check whether the Keylok macro requires a specific 32-bit or 64-bit version of Microsoft Excel to run correctly.

Frequently Asked Questions
Why does Excel automatically block my Keylok macro files?
Windows applies a security feature called 'Mark of the Web' to files downloaded from the internet or copied from other computers. You must manually unblock these files in their Properties menu before Excel's Trust Center will allow the macros to run.
Can Microsoft Support help me fix a Keylok dongle error?
No, Microsoft Support generally cannot modify, repair, or troubleshoot proprietary third-party macros. You must contact the specific software vendor that supplied the Keylok dongle for compatible files and updates.
Does it matter if I have 32-bit or 64-bit Excel installed?
Yes. Many hardware dongle drivers and their associated macros are specifically written for a certain architecture (usually 32-bit). If you are using 64-bit Excel with a 32-bit macro, it will fail to execute unless the vendor provides a 64-bit compatible update.
How can I tell if my Keylok dongle is recognized by my computer?
You can check this by opening the Windows Device Manager (search for it in the Start menu). Look under 'Universal Serial Bus controllers' or 'Other devices' to ensure the dongle is listed and does not have a yellow warning triangle next to it.
