No—not by itself. Bluetooth proximity features can reduce the chance that an unattended device stays accessible, but they are fallbacks, not theft-proof locks. Windows Dynamic Lock only locks an idle PC after its paired phone moves out of Bluetooth range; Android’s Extend Unlock can do the opposite and keep a phone unlocked near a trusted device. Use a strong screen lock and turn on your platform’s theft and recovery protections before anything goes missing.
What Bluetooth proximity locking can—and cannot—do
A proximity feature reacts to a Bluetooth connection or signal. It does not verify who is holding the device, prove that its owner is nearby, or guarantee that a lock will engage at the moment of theft. Signal behavior varies by device and surroundings, and a nearby trusted device can remain connected after a device changes hands.
No theft-prevention rate is established for these features in the cited platform guidance. Treat them as convenience safeguards against some situations, not as a substitute for a strong passcode, manual locking, or theft-specific account protections.
How the features differ
| Feature | What triggers it | What it means if a device is stolen |
|---|---|---|
| Windows Dynamic Lock | The paired phone’s Bluetooth signal falls below a threshold while the PC is idle. | It may lock an idle PC after you walk away, but it does not guarantee a lock if the PC is active or the phone stays nearby. Microsoft says it “doesn’t replace the need for the user to lock the computer.” |
| Android Extend Unlock | A trusted Bluetooth device remains connected after you unlock the phone once with a PIN, pattern, or password. | The phone can stay unlocked near that device, creating exposure if both are taken or the trusted device is nearby. |
| Apple Stolen Device Protection | Applies extra checks to selected sensitive actions, particularly when the iPhone is away from familiar locations. | It is not a Bluetooth proximity lock. It raises barriers to sensitive access and security changes after a phone is away from its owner. |
Will Windows Dynamic Lock protect a stolen PC?
Dynamic Lock is a backup for the moment you leave an idle Windows 10 or Windows 11 computer behind. It uses the Bluetooth signal from a paired phone; when that signal drops below a threshold, Windows can lock the PC. The key limitation is the idle-state requirement: it is not a guarantee that a PC will lock while someone is actively using it, or that it will be secured immediately when stolen. Microsoft describes Dynamic Lock as an additional barrier, not a replacement for locking the computer yourself. Microsoft’s Dynamic Lock documentation

Lock the PC manually before stepping away, especially where theft is plausible. Dynamic Lock is useful if you forget, but should not be the only protection between a thief and an open session.
Can someone use an Android phone if it is stolen near a watch or car?
Potentially. Android’s Extend Unlock can keep a phone unlocked while it remains connected to a trusted Bluetooth device. Google says Bluetooth connectivity can reach up to about 100 meters, depending on the devices and environment; that is a possible range, not a reliable boundary. A stolen phone may therefore remain near a trusted watch, car system, or other device long enough for Extend Unlock to keep it accessible. Google also warns that someone might imitate a trusted Bluetooth connection. Google’s Extend Unlock guidance

Review the trusted devices in Extend Unlock and remove ones that are usually carried or kept with the phone. Google specifically advises against trusting devices that are always with the phone, such as Bluetooth keyboards or cases. For higher-risk situations, Android’s Lockdown action temporarily disables biometric unlocking and Extend Unlock on the lock screen until the next unlock.
What iPhone theft protection adds
Stolen Device Protection is designed for what proximity locking cannot solve: a thief may already have the iPhone. For selected sensitive actions, it can require Face ID or Touch ID with no passcode fallback. Certain account or security changes can also trigger a one-hour Security Delay followed by another biometric check. Apple says the feature requires a passcode, Face ID or Touch ID, two-factor authentication, Find My, and Significant Locations, and is available on iOS 17.3 or later.

Enable both Find My and Stolen Device Protection before a theft. Apple lets users choose “Always” so the additional measures apply regardless of familiar location; this adds friction to some actions, but avoids relying on the phone’s location to trigger them.
What to do before and after a theft
Before a device goes missing
- Set a strong screen lock and lock the device manually when stepping away.
- On Windows, pair a phone for Dynamic Lock if useful, but do not rely on it instead of locking an active or unattended PC.
- On Android, remove trusted Bluetooth devices that tend to stay near the phone; use Lockdown when you need biometric and Extend Unlock access disabled on the lock screen.
- On iPhone, turn on Find My and Stolen Device Protection, and choose “Always” if you want its added measures regardless of familiar location.
After a phone is stolen
Use the platform’s lost-device controls promptly and secure the associated account. Apple’s guidance directs owners to mark a missing iPhone as lost; Stolen Device Protection’s checks and delays are intended to give the owner time to act, not to replace reporting the loss or securing the account.

What Bluetooth security research does—and does not—show
A 2025 paper presented at the USENIX WOOT conference analyzed the Master Lock Bluetooth Deadbolt D1000 under a specific attacker model involving proximity to the lock, recording encrypted Bluetooth Low Energy traffic, and injecting packets. The authors reported issues including session replay that could repeat commands such as unlocking, persistence after revocation, clock manipulation, audit-log tampering, and malformed messages that could disrupt or corrupt the lock. USENIX’s 2025 WOOT paper
That result is evidence about one physical deadbolt model and the stated attack conditions—not about Windows Dynamic Lock, Android Extend Unlock, or every Bluetooth product. It does illustrate why a Bluetooth connection or encryption claim alone is not proof that a product is secure.
