It should work fine. It sounds like a different sort of problem.

No, but there is a stub secret key that lives in the usual secret
keyring. This isn't a true secret key (it does not contain the actual
key data), but is the OpenPGP information (user IDs and other things),
along with a pointer that says "the key is on smartcard XYZ".
So if they can get ahold of your computer, someone could steal this
stub, but there is nothing secret about it, and it won't do them any
