AVD4001, 2nd generation doorbell cover

I can't remove the cover with the pin...........it worked before but not now.

If you mean you're trying to remove the doorbell from the mount, try pushing the doorbell into the mount while using the pin to release it. If it's wired to existing power, the wires may be bunched up causing the doorbell to be forced against the release.
