If your iPod shuffle is locked and can't sync, there are a few methods you can try to get access to it. See this article for help:
iPod: How to use the Screen Lock
You can unlock iPod in one of two ways:
- Enter the combination on iPod using the same controls you used to set the combination. If you do not enter the correct combination, the digits onscreen flash red. When you enter the combination correctly, iPod will unlock and return you to the last viewed screen.
- Connect iPod to the primary computer you use it with (the first one iPod synced with), and open iTunes. When you disconnect iPod from the computer, it will no longer be locked.
If you can't unlock iPod using either of these methods, you can restore your iPod to factory settings. Please note that this will erase all data on your iPod. Afterwards, you can add your music and data back to iPod.If you want to change the primary computer that your iPod is associated with, do this:
- Restore your iPod. Warning: The restore process cannot be undone. All of your songs and files will be deleted. Always make a backup of your important data.
- Connect your iPod to the computer that you want to be the primary computer.
- Open iTunes and synchronize.
