Removing the activation lock: handing your device over properly

The activation lock is a theft protection: it ties the device to your account so that after a reset it can only be put back into service with your credentials. That is a good thing, but it regularly becomes a stumbling block when selling, because many people forget to sign out.

Why this matters so much

A device with an active lock cannot be set up. That makes it neither sellable nor repairable in the sense of a full functional test. For the buyer it is worthless, and for a trade-in purchase it is too. Signing out is therefore the most important step before handing anything over.

The clean route while you still have the device

1. Create a backup. After this you can no longer get to the data.
2. Sign out: on an iPhone, tap your name at the very top of the settings and sign out. On Android, remove the Google account under Accounts. On Samsung, remove the Samsung account as well.
3. Unpair the device: if you wear a smartwatch with it, unpair it beforehand.
4. Erase all content and settings. Only now, not before.
5. Remove the SIM card.

The order matters: sign out first, then erase. Anyone who erases first and then notices that the account is still linked has to take the detour via remote removal.

When you no longer have the device in your hands

This can also be done afterwards. Sign in to the manufacturer's account on a computer, open the device overview and remove the device in question from the list. That releases the link remotely. With Apple this runs through the device list in your account, with Google through the account management. If the device has already been handed to someone, this is often the fastest solution.

When the device no longer starts

Even a phone that can no longer be switched on can be removed from your account remotely. That is exactly why a defective device is still sellable: the lock is released online, not on the device. If it is about recovering data before you hand it over, data recovery can help.

There is no reputable way around it

Offers that promise to remove someone else's activation lock for a fee are not reputable. The lock is built precisely to prevent that. If you are offered a used device with someone else's lock still active, stay away from it, more on this in buying used without getting burned.

Conclusion

Sign out, then erase, then take the SIM out. If you are too late, signing out remotely works through your account on a computer. After that, nothing stands in the way of selling or trading in. You will find all the steps in one place in the selling checklist.
