Tenorshare has updated its 4uKey iPhone Unlocker to support the new iPhone 18 series and expanded Activation Lock compatibility for devices running iOS 18 through iOS 26.1. The move matters because it extends the utility of a widely used unlocking tool to the latest hardware and a broad range of operating system versions, helping users avoid being locked out of their own devices due to forgotten passcodes, secondhand purchases, or other lock scenarios.
The update adds the iPhone 18 series to 4uKey's supported device lineup, according to the company. Users with newer iPhone models can connect their devices to 4uKey and check available functions based on the device model and iOS version. The current technical specifications list support for iPhone models ranging from earlier generations through the iPhone 18 series, as well as supported iPad and iPod models. This means owners of the newest iPhones are not left behind when they need to bypass an activation lock or remove a screen passcode.
Activation Lock support has also been expanded for compatible devices running earlier and newer supported iOS versions. According to Tenorshare's compatibility list, 4uKey supports Activation Lock removal on compatible devices running iOS 26.0–26.1. Supported models include iPhone 11 through iPhone 17 series devices, iPhone Air, and selected iPad models. For iOS 18.0–18.7.2, supported devices include iPhone SE (2nd and 3rd generation), iPhone XR, iPhone XS series, and iPhone 11 through iPhone 16 series, along with selected iPad models. Because support varies by device and iOS version, users should check the compatibility list before starting an Activation Lock-related process.
Determining compatibility does not require users to guess based on their iPhone model alone. The latest version of 4uKey can check the connected device directly. Users download and launch 4uKey iPhone Unlocker on a Windows PC or Mac, connect the iPhone or iPad with a USB cable, select the relevant unlocking or Activation Lock feature, and follow on-screen instructions to see whether the connected device and iOS version are supported. Tenorshare recommends checking the supported device list before purchasing or beginning an unlocking process, as available functions can vary by model and system version.
Beyond Activation Lock scenarios, 4uKey provides tools for several other common device lock situations, including screen passcodes, Apple ID, MDM restrictions, and Screen Time passcodes. The update is part of Tenorshare's continued effort to keep 4uKey compatible with newer iPhone generations and supported iOS releases. For users who rely on their iPhones for work, communication, and daily tasks, the expanded support may mean the difference between a usable device and a costly replacement.
