> You can lock the glovebox with a pin

That doesn't mean you can't put a touch button on the actual glovebox.

Use the UI (with a pin) to lock the glovebox so that it doesn't open when the glovebox button is touched, use the UI (with the same pin) to reverse that at a later stage.

Putting the button anywhere but on the glovebox makes non-fanboys seriously question the suitability of the car as a convenience.
