Trade Republic may decide to lock your card if we believe your card or account are at risk. We will let you know if we do so and guide you through the necessary steps to unlock your card or get a replacement.
In case of several consecutive unsuccessful payment attempts with an incorrect PIN, your card is automatically locked for security reasons. If you simply forgot your PIN, you unlock your card instantly in the app and retrieve your PIN. If these payments were attempted by someone who might have stolen your card, you will be able to terminate it and order a new one.
