Apple is continuing development of an unreleased iPhone security tool that could lock a device after it detects a theft-related snatching event. The iOS 27.2 beta contains internal references to the work, labeled “AutoLock,” as first reported by MacRumors.
The beta code suggests Apple may draw on the iPhone’s gyroscope, accelerometer and other sensors to identify abrupt movement associated with a stolen phone. A paired Apple Watch could also supply signals when it separates from the handset or loses communication with it.
AutoLock appears designed to weigh several theft signals
Movement would represent only part of the decision. The system may also respond to an extended loss of network connectivity or an iPhone that stays unlocked for a set period, two conditions that could raise concern after a device leaves its owner’s control.
Apple appears to have built safeguards into the selection process before it asks the phone to lock. Biometric verification, use of a foreground app and a recognized location could stop an incorrect response during everyday situations such as travel, a poor connection or normal device handling.
A lock would activate Apple’s existing theft protections
After the system confirms a theft signal, the iPhone would lock and turn on Stolen Device Protection. That existing setting requires biometric authentication for certain sensitive actions outside recognized locations, and it can impose a delay before a user changes an Apple Account password.
The addition matters because a snatched, unlocked phone can give a thief immediate access to apps and account settings before an owner can react. Google’s Android already offers Theft Detection Lock for snatch-and-grab incidents, while AutoLock could give iPhone owners a sensor-based response that feeds directly into Apple’s stricter protection for sensitive actions.
Apple has not announced AutoLock or confirmed that it will reach the public. The company has not specified a release date, supported iPhone or Apple Watch models, thresholds for movement, connectivity loss or unlock duration, or how the system would handle false positives in routine use.
