How do I report a lost or stolen debit card?

To report a lost or stolen debit card, you can contact KeyBank immediately through their customer service phone line, online banking portal, or mobile app. It is important to report the card as soon as possible to prevent any unauthorized transactions. KeyBank will then deactivate the card and issue a replacement with a new card number to ensure the security of your account. Remember to monitor your account for any suspicious activity and update any automatic payments associated with the lost card to the new one once it arrives.
