Yes. You will need a new registration key if:
PalmOS Software: You change your HotSync Name
Windows Mobile Software: You change your Owner Name
Windows PC Desktop Software: You change your computer or reinstall Windows with a different name. This is necessary only for "Desktop" versions of our applications (like TealAuto Desktop or TealTracker Desktop) that run on your PC.
We recommend using the same DeviceID when purchasing a new device, as this will allow you to use your existing registration keys.
However, for one small processing fee, you may request that we generate new registraton keys for all your registered products. The fee covers our costs to look up, verify, and process these requests.
You may request this at most once per calendar year by visiting our Customer Database Page.
Make sure all keys are listed under the same email address as any missing ones will not be regenerated. You may change the email addresses associated with individual orders on the same page listed above. If you have both Desktop and Handheld apps or registrations for more than one DeviceID, be sure to enter the DeviceID you want to change from in the "Previous DeviceID" field of the checkout form.
