They always seem to disappear at the most inopportune times, but there are devices that exist to locate your missing house keys and car keys. Luckily, you can add another type of key finder to your arsenal: a similar tool has been created for finding those sometimes elusive software product key codes you used to originally install software such as Microsoft Office 2003, 2007, 2010, or 2013.

What Are You Looking For?

It helps to know what you’re even looking for, right? Key codes can, of course, vary from product to product but are typically alphanumeric strings separated by dashes.


The following are suggestions for free software product key finder programs. These will hopefully help you find your key code, but if you run into any snags, also check out my more detailed instructions for your version of Microsoft Office:

This list features free key finder utilities because in general, a lot of users can get along just fine using a free key finder tool. However, corporations with a large number of installations may benefit from a more professional grade version.

How Do Key Finder Programs Work?

Key finder programs can retrieve software product codes because the information should already be stored in your computer registry from when you originally installed the program. These programs seek, find, and possibly unencrypt the code so you can re-enter it.

What is a Software License?

When you purchase software, the license is for a distinct individual or group’s use, even if that license extends to a certain number of computers. Software companies protect this interest by issuing product key codes.

Are Product Key Finders Risky to Use?

Not typically, but you should still keep in mind that choosing to use these tools is up to your discretion. If your antivirus software blocks the program, for example, while you may not really have a threat on your hands, you may want to think twice until you are able to check it out further.

Volume License Key Codes

If a key code finder returns something strange, containing repeated letters or symbols or something that is obviously not a real product key code, it may have been part of a volume license deal. In this case, you may need to contact the originator servicing that deal to obtain a product key code. Alternatively, refer to the Microsoft Volume Licensing Service Center (VLSC) site.

Manufacturer Sticker Codes

Don’t get confused if you see a different code stickered on your computer or device. This could be a manufacturer’s code for the hardware, rather than the true product key code for your software or operating system.
