Require product key to be re-entered after deactivating computer

If I activate a computer using a product key and then later deactivate that computer, the next time I go to TurboActivate and click 'Activate', it no longer prompts me for a product key and instead just uses the previously used product key automatically.

How can I switch that computer to using a different product key after it has been deactivated from the original product key?

For example suppose there are 2 product keys:Key 1: the 'lite' feature is enabledKey 2: the 'pro' feature is enabled

A user is currently using the product key with the 'lite' feature and wants to switch to a different product key that has the 'pro' feature. The user deactivates the product key with the 'lite' feature using TurboActivate. The user now tries to enter the different product key that has the 'pro' feature but can't because TurboActivate no longer shows a textbox for entering a new product key.

When you call TA_Deactivate() there is the erasePkey option. Set it to true to get the behavior you're looking for.
