Credit card is locked: 1. If the credit card is overdue and has not been repaid for more than two or three months, the bank card will lock the credit card. 2. In order to ensure the safety of users' funds, the bank will temporarily close the cardholder's bank account because the cardholder entered the wrong password for more than 3 times when logging in online banking. 3. The bank's risk control system monitors the cardholder's cash-out behavior, and will also lock its cash-out bank card.

1. If the credit card is frozen due to overdue, you should return the overdue amount as soon as possible. After paying off the arrears, you can call the credit card center of the issuing bank, and the general bank will unfreeze it.

2. If the card is frozen because of the lost or stolen credit card, the card issuing bank will unfreeze it after the relevant matters are handled, or it can take the initiative to ask for unfreezing.

3. If the bank recognizes the cardholder's cashing, the card can't be unsealed. However, if there is evidence to prove that it is not cashing by itself, but there is something wrong with the merchant's Pos machine, the credit card center may unseal it.
