The popularity of credit cards provides us with a lot of convenience. Different credit cards can provide different needs, and we can enjoy interest-free advance consumption by using credit cards. However, some card friends have encountered the situation that their credit cards are locked. Many card friends themselves don't know what caused it, let alone how to solve it. So how to unlock the credit card when it is locked?

let's look at three reasons why credit cards are locked.

1. Wrong password. The credit card password will be locked if you enter it incorrectly for 3 times. But now it is a small amount of confidentiality, and this situation is not often locked. If the wrong password is locked during large consumption, you can call the customer service of the issuing bank to ask how to unlock it.

2. If the bank detects a risky transaction, the card will be locked. Frequent POS machines for large cash withdrawals and large cash withdrawals. Some cardholders installed their own POS machines and swiped their own credit cards, which did not produce real transactions, and some consumption amounts were different from the actual prices of goods. If this happens, you must use the card reasonably.

3, overdue locked. The consequences of overdue are very serious, which not only affects the credit information, but also will be locked if it is overdue. So if you use a credit card, you must repay it in time.
