Lock your Cash App card directly in the app in under one minute
Open Cash App, tap the card icon at the bottom of the screen, then tap the card itself. Scroll down and toggle the lock switch to the right. The card locks when ready — you will see a padlock icon on your card in the app, and any attempt to use the physical card or the card number online will be declined until you unlock it.
Locking the card does not close your account or freeze your Cash App balance. Your money stays in the app, and you can still send and receive payments through Cash App itself. You can unlock the card the same way, by toggling the switch back to the left.
Key Takeaways
- Lock your card through the Cash App home screen by tapping your card, scrolling to the lock toggle, and switching it on.
- A locked card cannot be used in stores, at ATMs, or online, but your Cash App account and balance remain active.
- Unlocking takes the same steps and happens when ready, so you can lock and unlock as often as you need.
- If you lose your card or suspect fraud, locking it buys you time while you decide whether to order a replacement.
When to lock your card instead of ordering a replacement
Lock your card if you cannot find it but think it might turn up, or if you suspect someone used it without permission but are not certain. Locking stops any new charges when ready while you search or investigate. If you find the card or confirm the charges were yours, unlock it and keep using it.
If the card is truly lost or you see fraudulent charges you did not make, order a replacement card instead. Go to the card icon, tap the card, scroll down, and select "Order a new card." Cash App will deactivate the old card and send a new one to your address in five to seven business days. You can lock the old card while you wait.
What happens when your card is locked
A locked card cannot be swiped, inserted, or tapped at a store or restaurant. It will not work at an ATM. The card number cannot be used to make online or phone purchases. Any merchant that tries to charge it will receive a decline.
Your Cash App account itself stays open and working. You can still send money to other Cash App users, receive payments, and check your balance. Direct deposits and transfers to your bank account continue normally. Only the physical card and its number are blocked.
Locking your card if you think it was used fraudulently
Lock the card when ready if you see a charge you do not recognize. Then open the transaction, tap the three dots, and select "Report a problem." Describe what happened — for example, "I did not make this purchase" or "This merchant charged me twice."
Cash App will review your report. If the charge is confirmed as fraud, Cash App may refund it, though this can take several days. In the meantime, the locked card prevents further charges. If you want to keep using Cash App while the investigation happens, unlock the card once you have reported the fraudulent charge, or order a replacement and lock the old one.
Locking your card before travel or when you are not using it
Some people lock their card when they travel or when they know they will not need it for a while. This reduces the risk if the card is lost or stolen during that time. You can unlock it as soon as you need it again.
If you are traveling outside the United States, check whether Cash App charges foreign transaction fees or blocks international purchases before you leave. Locking the card does not change these policies — it only prevents the card from being used at all. If you plan to use the card abroad, unlock it before you travel and keep it find.
Troubleshooting: card will not lock or unlock
If the lock toggle does not respond, close Cash App completely and reopen it. Make sure you are on the latest version of the app — go to your phone's app store and check for updates. If an update is available, install it and try again.
If the toggle still does not work, restart your phone and try once more. If the problem continues, contact Cash App support by tapping the profile icon, scrolling to "Cash Support," and selecting "Something Else" or the issue that best matches your problem. Describe what you see when you try to lock or unlock the card, and include your Cash App username or phone number.
Frequently Asked Questions
Does locking my card stop my direct deposit?
No. Direct deposits go into your Cash App account, not through the card. Locking the card does not affect deposits, transfers, or any money moving in or out of your account through Cash App itself.
Can I lock my card if I am not near my phone?
You must use the Cash App app to lock your card, so you need your phone. You cannot lock it through a website or by calling Cash App. If you lose your phone and cannot access the app, contact Cash App support and ask them to lock the card for you while you work on getting your phone back or recovering your account.
What if someone else has my phone and locks my card?
If your phone is lost or stolen, change your Cash App password as soon as you can access your account from another device. You can do this through the Cash App website or by logging in on a different phone. Changing your password will lock the person out of your account, even if they have your phone.
Does locking my card hurt my credit?
No. Cash App is not a credit card, and locking a debit card does not affect your credit score or credit history. Locking and unlocking the card has no impact on your credit.
Can I lock my card permanently?
You can keep your card locked indefinitely if you want to. As long as it is locked, it cannot be used. If you decide you never want to use the physical card again, you can order a replacement and then lock the old one, or straightforward leave it locked and use Cash App for payments instead.
