Visit on a weekday or Saturday morning and ask for a new PIN if you still have your unlock code.
Bring the card and any PIN/PUK letter you still have. Ask staff which recovery route applies before ordering new codes. For codes ordered through the municipality, collect at the ordering counter; federally ordered codes are collected at the counter named in the notification. Keep your codes private.
