Frequently Asked Questions 



Q: What is a pre-owned/recycled license key?


A pre-owned key is a license that has already been used to install/activate a particular software package. For example, on a laptop in a business environment. In most cases, the laptops are written off within 3-5 years, which means that the laptop needs to be replaced. A new laptop usually includes a new license code for the operating system, for example. The license code on the old laptop can then be reused/activated.



Q: Why do I get a Microsoft Piracy Warning?

Unfortunately, not all pre-owned licenses are reactivated correctly. This may cause you to receive the standard Microsoft warning for software piracy. 



Q: Why doesn't my license work immediately?

Eurokeys sells pre-owned licenses. These licenses were previously activated, but because of the replacement of the pc/laptop, these licenses are now no longer active. The license will have to be reactivated. In some cases, this 'reactivation' may not go right away. In 90% of the cases where it doesn't work out right away, the license will still come into effect after a re-activation by phone. 


Of course you will receive a guarantee that the license works 100%!


So you are never at risk that you pay for a product, but end up with a non-working license!


In case of a problem, you can always download a trial version from our website first. We will gladly support you in all cases.


Pre-owned licenses are divided into the following categories:

Grade C 20% chance of activation by phone

Grade B 5% chance of activation by phone

Grade A works immediately (delivery time 1-2 days)


Q: Why did you fail to reactivate the first time?

Microsoft's focus is on selling the latest software products. As a result, the reactivation of used licenses is not always given the right priority.


Note: Did you use Office 365 for this? Preferably create a NEW Microsoft Account. A small number of our customers experience activation problems because Office 365 is linked to your account at the same time as our license. This problem is difficult to solve! Make sure that Office 365 is properly removed and create a new Microsoft Account. This can be done with an existing e-mail address, see installation instructions below.


Q: Where can I enter the product code?


Office 365, Office 2019, Office 2016 and Office 2013 (PC and Mac)


Step 1: Go to


Step 2: Sign in with your Microsoft account, or create an account if you don't have one. Remember this account, so you can install or reinstall Office later without a product key.


Important: If you are renewing an Office 365 subscription, enter the Microsoft account associated with your subscription. I forgot my Microsoft account.


Step 3: Enter your Office product key, without bars.


Step 4: Follow the instructions to complete the redemption process.



Q: Where can I download my product?

Office and Windows can be downloaded from the following page, Downloads



Q: Is there a single product activation?

Sometimes it is necessary to use the option Activate by phone. 

In the activation window you choose for telephone activation.


Then use this tool from Microsoft.



Q: What is a license guarantee?

When you purchase one of our licenses, we guarantee you a 100% operation of your license. We will support you until the license key is activated, or we will exchange the license key for a valid code.


In addition, you can always download a valid trial version of the software package you wish to purchase.


Q: Why is pre-owned software cheaper than regular software?

Microsoft makes strict agreements with its sales channel regarding the sale of new software packages. As a result, these points of sale are bound by these price agreements.  We sell pre-owned software, which comes from used PCs and therefore no longer falls under the Microsoft sales policy. This allows us to have a more flexible pricing policy. 


Q: What are MSDN Licenses?

Microsoft Developer Network (MSDN) licenses are rights granted to developers who work with Microsoft products for the purpose of testing software. These licenses are in some cases provided free of charge and have no commercial value. The use of MSDN licenses is therefore strictly prohibited for companies and individuals and can lead to high fines! 



Our strict purchasing policy obliges our suppliers to issue only OEM, Retail and OLP licenses. We also check each license for legality, activation and availability. This gives you the guarantee that the license you purchase from Eurokeys can be used for the purchased software.


Q: What kind of support do you offer?

During office hours, your local contact is available by email and phone. The quickest way to get in touch with the support department is by email.


We offer you a 100% guarantee that your license code works. We will do everything we can to help you on your way.  We would like to ask you first what steps you have already taken to get the product working and if necessary, we will watch with you through a support program.
