How to Fix If Unlock with Apple Watch is Broken on the iPhone 13


iOS 15 has landed, and unsurprisingly, this update is chockfull of features that make life easier for us in newfound ways.  For example, if we have the Apple Watch and an iPhone, we can now unlock our iPhone with the Apple Watch! This is true only for Face ID-equipped iPhones only, though.


Why did Apple bring this particular feature only to Face ID-equipped iPhone models? This was a direct response by Apple to the global coronavirus pandemic wherein people with Face ID-equipped phones found themselves unable to unlock their phones due to the face masks.


But Apple has identified an issue where Unlock with Apple Watch may not work with iPhone 13 devices after the iOS 15 update. You might see “Unable to Communicate with Apple Watch” if you try to unlock your iPhone while wearing a face mask, or you might not be able to set up Unlock with Apple Watch.


Apple has warned owners of its new iPhone 13 model that they might not be able unlock their phone with an Apple Watch due to this software glitch.

If everything seems to be in order and you are still unable to unlock iPhone with Apple Watch after the iOS 15 update, there are a few steps you can take.

1. Restart the iPhone and key in your passcode when it boots up.

2. Restart the Apple Watch similarly.

3. Ensure that Unlock With Apple Watch is activated!

This method can temporarily solve the problem, but it may happen again in the future.

Good news is that Apple is lining up a software update that should resolve the problem, according to a new support document. Althought the specific release time is still uncertain.

4. Reset Your Network Settings.

But it is not work for iOS 15 user, the current way to solve this problem briefly is to restart the phone, but the problem will still recur.

“Creating greater access to Apple genuine parts gives our customers even more choice if a repair is needed,” said Jeff Williams, Apple’s chief operating officer. “In the past three years, Apple has nearly doubled the number of service locations with access to Apple genuine parts, tools, and training, and now we’re providing an option for those who wish to complete their own repairs.”


To ensure a customer can safely perform a repair, it’s important they first review the Repair Manual. Then a customer will place an order for the Apple genuine parts and tools using the Apple Self Service Repair Online Store. Following the repair, customers who return their used part for recycling will receive credit toward their purchase.
