I admit it. I have a keyfinder device for my house keys and car keys. Luckily, 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 You Are 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.


Example: XXXXX-XXXXX-XXXXX-XXXXX-XXXXX

The following are my suggestions for free software product keyfinder 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:

Professional Key Finder Software

In this list, I have featured the free key finder utilities because in general, a lot of users can get along just fine using a free key finder tool. Enterprises 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 as with all software, don’t take my or anyone else’s word for it. 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, I personally would think twice until I checked it out further.

Volume License Key Codes

If a key code finder returns something weird, containing repeated letters or symbols or 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 origniator 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.

Best of luck with your software key code and please let me know if you have any questions.
