Other FAQs:
Why are you required to order an open key for funded devices?  
In July of 2015, Medicare (CMS) updated the National Coverage Determination (NCD) for Speech Generating Device, which allows Medicare beneficiaries the ability to open their SGDs and grants access to non-covered services such as the internet, video conferencing etc. These services are clearly noted in the NCD as non-covered services by Medicare and must be paid for by the beneficiary.
Tobii Dynavox, nor any other supplier, should be providing an open key to a beneficiary at no cost due to prohibiting law. Please note that no employee of Tobii Dynavox is allowed to purchase an open key for a beneficiary.  As Medicare providers, violation of this policy is considered fraudulent.

When I buy an open key, how does the charge appear on my bank/credit card statement? 
The charge appears as Tobii Dynavox LLC.

We have tax exempt status.  Will this be accounted for when purchasing open keys online?
If you need to purchase an open key exempt of tax, or with a Purchase Order or check, please reach out to Customer Service directly at 1-800-344-1778 or at CSS@tobiidynavox.com. This purchase process will NOT support those payment needs and only supports taxable, credit card orders.

After scanning the QR code/entering the new product key, my device is still locked.  What should I do?
You may have an older version of the configuration manager.  In order to update this, you will need to run Update Notifier.  Typically, Update Notifier can be found on your device’s desktop.  Once everything is up to date, run configuration manager again it should unlock the device.  If that doesn't do it, make sure you are connected to the internet.  If all else fails, contact Technical Support at 1-800-344-1778 or support.na@tobiidynavox.com.

I am trying to order the open key on a closed Windows device.  However, when I go to enter my credit card info those fields won't finish loading and I can't enter anything.
This is due to intouch lock blocking access.  At the moment, you'll want to order the open key online from another computer.  We plan to address this in the near future, though.
