Step-by-Step Guide to Replace Your BMO Debit Card

  • Log In: Sign into BMO Mobile Banking or BMO Online Banking using your credentials.
  • Navigate to Account: Select your primary bank account from the dashboard, then click on Manage Card on the account details page.
  • Report the Issue: Choose the It's lost or stolen option from the menu. (If your card is just damaged, look for the replacement option for damaged cards).
  • Confirm Details: Verify your mailing address and contact information on the screen, then Submit your request. Your old card will be permanently deactivated.

Pro-Tip: Before your new debit card arrives, remember that your core bank account number remains the same, but the 16-digit card number and expiry date will change. You must update any online merchants or subscription services that bill directly to your debit card once you activate the replacement.

Troubleshooting Common Replacement Pain Points

  • MFA Verification Delays: If you are unable to receive the Multi-Factor Authentication (MFA) text code to log in, you cannot order a replacement online. Call 1-800-361-3361 to verify your identity over the phone instead.
  • Browser Errors: If the Manage Card page fails to load or loops indefinitely, clear your browser cache and cookies, or try submitting the request through the BMO Mobile App instead.
  • Locked User ID: If your digital access is suspended due to multiple failed login attempts, you must reset your password or call customer support to unlock your profile before you can report the debit card.

Efficiency Hack for Safer Replacements

If you have simply misplaced your card and want to search for it before permanently canceling it, use the Lock your card feature in the mobile app. This instantly freezes all transactions. If you find the card, you can unlock it with one tap. If you cannot find it after 24 hours, proceed with the permanent replacement process.
