What is the iTunes Lockdown Folder?
The iTunes Lockdown folder is a hidden folder that contains authentication certificates and keys that allow iOS devices like iPhones and iPads to sync content from iTunes. It restricts access to the synced content, like apps, music, movies, and more, to prevent unauthorized use.
The lockdown folder contains cryptographic keys used to encrypt backup data from iOS devices. It allows iTunes to restrict restores and syncing to only work with the authorized computer the device was originally synced with. This is an anti-piracy measure to ensure synced iTunes content can’t be freely copied and shared.
The folder also contains pair records that associate an iOS device with the authorized computer, and device-specific entitlements granted for syncing. All of this allows secure synchronization while blocking unauthorized access.
By default, the lockdown folder is hidden. Its contents are critical for syncing iTunes content and restoring device backups. If the folder becomes corrupted or keys are invalid, syncing issues occur and a reset may be required.
When to Reset the Lockdown Folder
There are a few common situations when you may need to reset the iTunes lockdown folder:
Trouble Accessing Content
If you are having issues syncing your iPhone, iPad, or iPod Touch to iTunes and accessing the content stored on the device, resetting the lockdown folder may help. This is because the lockdown folder contains the pairing records between iTunes and your iOS devices. If these records get corrupted, it can prevent syncing and accessing content properly. Resetting the folder clears out these records so they can be recreated cleanly.
Forgotten Passcode
If you forget your passcode for your iOS device, you will need to restore it through iTunes. However, if the lockdown folder contains outdated pairing records from before you forgot the passcode, it may prevent the restore process from completing properly. Resetting the lockdown folder first clears out these old records so the device can be restored cleanly.
After Restoring from Backup
Sometimes after restoring an iPhone or iPad from a backup, you may encounter errors or issues syncing the device. This is often due to outdated lockdown folder records from before the restore. Resetting the lockdown folder ensures any old records are cleared out so the device can sync properly with the current state after being restored.
Before Resetting the Lockdown Folder
There are some important things you should do before resetting your iTunes Lockdown folder. First, try entering your passcode on the locked device again. Sometimes there may be a simple explanation for why it’s not unlocking. Double check that you’re using the correct passcode.
If you’ve tried the passcode multiple times and the device remains locked, you may need to contact Apple support. An Apple support representative can walk you through troubleshooting options and determine if resetting the Lockdown folder is necessary.
Finally, make sure to back up your content. Resetting the Lockdown folder will wipe all sync data between your computer and iOS device. You’ll lose any music, photos, contacts, calendars and more that were synced. So be sure to back up everything first through iTunes or iCloud.
According to iMobie, it’s important to try your passcode and contact Apple support before resetting the Lockdown folder, as there may be another solution that avoids data loss.
Reset the Lockdown Folder on Windows
To reset the iTunes lockdown folder on Windows, first quit iTunes and disconnect any iOS devices from your computer. Then, navigate to the lockdown folder location:
C:\Users\\[username]\AppData\Roaming\Apple Computer\iTunes\iPhone Software Updates
You can access this folder location quickly by typing %appdata%\Apple Computer\iTunes\iPhone Software Updates into the Windows file explorer address bar and hitting enter.
Once you have navigated to the lockdown folder, delete all files and folders inside it. With the lockdown folder emptied, you can restart iTunes, which will regenerate the lockdown folder with default files and settings, effectively resetting it.[https://osxdaily.com/2016/01/21/ios-lockdown-folder-location-reset-lockdown-mac-windows/]
After restarting iTunes, you should be able to sync and backup your iOS devices as normal again.
Reset the Lockdown Folder on Mac
To reset the iTunes lockdown folder on a Mac, you first need to navigate to the folder location. The default location for the lockdown folder on Mac is:
/Users/YOURUSERNAME/Library/Application Support/MobileSync/Backup
To quickly access this folder in the Finder, go to Go > Go to Folder and paste in the above file path, then hit return. This will open the lockdown folder.
Once you have accessed the lockdown folder, delete all files and folders inside of it. After deleting the contents, you can close the folder.
The last step is to restart iTunes. When iTunes reopens, it will automatically recreate a new empty lockdown folder. This resets the lockdown database and often resolves issues syncing iOS devices.

Reset the Lockdown Folder on iPhone/iPad
If you need to reset the lockdown folder for your iPhone or iPad, you have two main options: erase the device or restore from a backup. Erasing the device will completely wipe it and remove any connection with the previous lockdown folder. Restoring from a backup allows you to keep your data while still resetting the lockdown folder.
To erase your iPhone or iPad:
- Go to Settings > General > Reset
- Tap “Erase All Content and Settings”
- Enter your passcode if prompted
- Tap “Erase [device]” to confirm
This will erase your device and disconnect it from any previous lockdown folder. You’ll then need to set up the device again as new.
Alternatively, you can reset the lockdown folder by restoring from a backup:
- Connect your iPhone/iPad to your computer
- Open Finder or iTunes
- While holding Shift, click “Restore Backup”
- Select a backup file to restore from
This will install the backup while resetting the lockdown folder. Make sure the backup you restore is not corrupted.

Reset the Lockdown Folder on Apple TV
If you are having issues syncing or connecting your Apple TV to iTunes after deleting the lockdown folder, you may need to reset your Apple TV device completely. This will erase all content and settings on the Apple TV and allow you to set it up as new. Be sure to back up any important data before proceeding.
To reset an Apple TV 4K or HD:
1. Go to Settings > System > Reset.
2. Select “Reset and Update” or “Reset All Settings”. This will reset the device to factory settings.
After resetting, you will need to set up the Apple TV as a new device. Go through the on-screen setup, signing in with your Apple ID and selecting preferences. Once set up, reconnect the Apple TV to iTunes on your computer to sync content. The lockdown folder will be recreated during this process.

Prevent Future Lockdown Folder Issues
To avoid encountering lockdown folder problems again in the future, there are a few best practices to follow:
Remember your passcode – Having a passcode set on your iPhone or iPad is essential for protecting your data, including content synced through iTunes. If you forget your passcode, you may need to reset your device, which can corrupt the lockdown folder. Be sure to remember your passcode or have a backup option for accessing your device if needed.
Remove content before restoring – If you do need to reset your device due to a forgotten passcode, be sure to manually transfer photos, music, videos, and other media off the device first. You can do this by connecting to a computer and syncing the content. This prevents losing your data when the device is reset.
Sync content regularly – Don’t allow weeks or months to go by without syncing your iPhone or iPad to your computer. Regularly connecting and syncing ensures the lockdown folder stays up to date and minimizes discrepancies between the device and your iTunes library. Frequent syncing can prevent lockdown folder corruption.
By remembering your passcode, manually offloading content before resets, and regularly syncing your device, you can avoid lockdown folder problems that require resetting it in iTunes.
Restore Content After Reset
After resetting the iTunes lockdown folder, you will need to restore your content. Here are some ways to do that:

Sign in to iTunes/App Store: Make sure to sign in to the iTunes or App Store with your Apple ID. This will allow you to re-download any previous purchases you’ve made. Your purchase history is tied to your Apple ID, so sign-in is required to download those items again.2
Re-download previous purchases: You can browse your purchase history in the iTunes or App Store and re-download apps, music, movies etc. This is an easy way to restore your purchased content.
