I have a Digipass GO6 authenticator from the FFXIV version 1 collector's edition. Unfortunately, it's started to take considerable effort to get the OTP to display; the button is failing to activate most of the time. Because of the fact that this is an auth from the 6th Astral Era, I'd rather be able to keep this authenticator for as long as possible instead of having to replace it. (Rather a point of pride, personally.)
I'm thinking of prying it open myself to replace the membrane switch. The thing stopping me is concern over whether or not it will continue to work properly. I know that there are tamper-resistant features on the authenticator (having also looked at the manufacturer's website). It appeared to me that these features were centered around making sure the tampering was apparent, rather than towards breaking the device for security purposes. This I can live with, but I'm not sure that my interpretation is correct.

Basically: If I open my authenticator (or rip off the big red button) and replace the switch, will it still work?
