Q: I'm getting a message on my watch "Device Locked"  Unlock iPhone to start using Apple Watch" So I unpaired it from my iPhone, now I can't pair it again.

Hi

Follow these steps to erase your locked watch and re-pair it with your iPhone:

• Connect your watch to its charging cable - with power connected.
• Press and hold the side button until you see the Power Off slider.
• Press firmly (ie more firmly than usual) on Power Off and then tap on Erase all content and settings.
• Then re-pair your watch using the Watch app on your iPhone, choosing to Restore from Backup when offered the option.

Set up your Apple Watch - Apple Support

If you forgot the passcode for your Apple Watch - Apple Support

Upon re-pairing your watch, you might wish to consider using these settings:

- On your iPhone, in the Watch app, go to: My Watch (tab) > General > Wrist Detection - turn this on.

- On your iPhone, in the Watch app, go to: My Watch > Passcode > Turn Passcode on (choose either a Simple Passcode or a more complex one).

- Also on the Passcode settings screen, enable Unlock with iPhone.

After putting it on your wrist, your watch will then unlock after whatever you do first: either unlocking your watch manually (by entering the passcode directly on your watch) or unlocking your iPhone.

It will then remain unlocked (including when the screen is asleep) until you remove it from your wrist. When you remove your watch, it will lock automatically.
