If you SecureKey or SREDkey unit displays "Activating..." when it is plugged in. And, it never changes to "Ready" or "Swipe Card or Key-in Card Number", this indicates the device is non-functional and will need to be returned to the provider or sent into ID TECH on an RMA for service. If you are with 30 days of the date of purchase, you should return it to the provider. The unit has a manufacturer's warranty for 1 year from the date of purchase.
SREDkey units must be injected with an encryption key to function at all. SecureKey units will output card data in plain text (not encrypted) unless they are injected with a key. The key is usually injected at the time of purchase by the provider.
