Observed behavior

Solution 1Recommended

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.

1
Install driver updates

Install the latest Keylok driver and application version provided directly by your third-party software vendor.

2
Check Device Manager

Open Windows Device Manager to confirm the Keylok dongle is detected successfully and has no yellow warning triangles.

3
Unblock the macro file

Open Windows File Explorer, locate the problematic macro file, right-click it, and select 'Properties'.

4
Apply changes

At the bottom of the 'General' tab, check the 'Unblock' box if it is visible, then click 'Apply' and 'OK'.

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.
