You get 3 chances to enter your PIN correctly. If you enter the wrong PIN 3 times, your debit card will be locked.
My PINsentry card reader says 'PIN locked'. What does this mean?
To unlock the PIN, you need to visit a cash machine. You also need to know the correct PIN. At any UK ATM, select ‘PIN services’ and follow the instructions.
Get an instant PIN reminder if you can’t remember your PIN.
If you live abroad and locked your PIN, we may need to send you a new card. For details, call Telephone Banking on (if you’re registered).
