Schlage Locks Just Got Safer-But There's A Catch
Schlage Security Update Fixes You Shouldn't Ignore
Recent Schlage security updates have focused on firmware fixes for Control and Control Mobile Enabled locks, including communications hardening, error handling improvements, and bug fixes that reduce the risk of lock outages or unstable gateway behavior. The most notable updates in the available release notes are the November 2024 Control firmware 03.15.01 for older pre-July 30, 2019 locks, and the June 2025 Control Mobile Enabled firmware 04.16.01 / 05.15.01, both of which emphasize security enhancements alongside reliability improvements.
What changed
Schlage's recent firmware notes point to a practical security pattern rather than a single headline vulnerability: the company keeps tightening the lock-to-gateway communication path, fixing parsing issues, and adding protections around data transfer and error conditions. In the November 2024 release, Allegion documented "added protection to buffer used for data transfer between Lock and GWE" and "fixed hard faults that could occur during GWE communication," while the June 2025 release added fixes for schedule corruption, read attempts during self-test, and UI consistency after relock states.
For owners, the key takeaway is simple: these are the kinds of updates that can prevent a smart lock from becoming unreliable at the exact moment you need it most. They also matter because some ecosystem partners have tied observed lock instability to upstream security patches, suggesting older firmware implementations may not handle newer secure communication requirements cleanly.
Recent release timeline
| Release date | Product family | Version | Main changes |
|---|---|---|---|
| November 2024 | Schlage Control | 03.15.01 | Gateway disconnect/reconnect improvements, added buffer protection, hard fault fixes |
| June 2025 | Schlage Control Mobile Enabled | 04.16.01 / 05.15.01 | Schedule parsing fix, relock UI fix, power-on credential read fix, updated Engage audits |
| 2024-2025 ecosystem impact | Schlage older integrated locks | Security patch compatibility | Some users reported offline behavior after a hub/security patch, linked to secure transmission handling |
Why it matters
Security updates for smart locks are not just about closing theoretical holes; they can directly affect whether your door lock stays connected, authenticates correctly, and responds to app or hub commands. In one SmartThings support thread, escalation notes said a recent security patch from a chipset maker exposed a protocol-reuse behavior in older Schlage firmware, and the platform would not roll back the patch because it would create a vulnerability elsewhere.
That matters because a smart lock is part security device and part networked computer. If a firmware build assumes an older secure-communication behavior, a new patch elsewhere in the chain can make the lock appear "broken" even when the real issue is compatibility, not a simple hardware failure.
Who should update now
- Owners of Schlage Control locks manufactured before July 30, 2019 should check for firmware 03.15.01, because that release was specifically made for that legacy hardware set.
- Owners of Schlage Control Mobile Enabled BE467/FE410 locks should look for firmware 04.16.01 or 05.15.01, which include both feature updates and bug fixes tied to security and stability.
- Anyone using a hub or integration layer, such as a smart home platform, should verify that the lock, hub, and mobile app are all on the latest supported versions, because mixed-version environments are where compatibility issues often appear.
How to update safely
- Identify the exact Schlage model and manufacturing date from the lock body, packaging, or app record.
- Check whether the lock uses a gateway, hub, or direct mobile connection, since the update path can differ by product family.
- Charge or replace batteries before updating, because a low-power interruption can complicate firmware installation.
- Update the lock, then update the app and any connected home platform so all components negotiate the same security behavior.
- Test lock and unlock actions from both the keypad and the app after the update is complete.
Observed problems
Reported issues around recent Schlage updates have centered more on connectivity and interoperability than on confirmed breaches. The clearest example is the offline/online behavior reported in smart home communities after a security patch changed secure-communication assumptions, with escalation notes advising that some older locks may need replacement or manual operation until Schlage resolves the problem.
Schlage's own release notes also show a recurring theme of hardening edge cases: corrupted schedules, unsupported JSON parsing, and power-on credential reads are all the kind of low-level software issues that can create user-facing failures if not fixed.
What users should watch
Two practical signals matter most after a Schlage update: whether the lock still responds reliably, and whether the app or hub shows the correct status. If the lock starts dropping offline, failing to relock, or desynchronizing its reported state, that is often a clue that a firmware, gateway, or platform compatibility issue needs attention rather than a dead lock.
It is also smart to keep an eye on vendor release notes, because Allegion explicitly advises customers to use the latest firmware to benefit from "the latest functionality, bug fixes, and security enhancements".
"Use the latest firmware release to take advantage of the latest functionality, bug fixes, and security enhancements."
What this means now
The most recent Schlage security updates are best understood as maintenance releases with real security value: they reduce the odds of communication faults, improve resilience against malformed data, and align older locks with newer ecosystem security expectations. For most users, the right move is to update promptly, retest the lock, and treat any new offline behavior as a compatibility warning worth investigating.
Frequently asked questions
Key concerns and solutions for Schlage Locks Just Got Safer But Theres A Catch
Are there any known breaches in Schlage smart locks?
In the sources reviewed here, no confirmed company-wide breach was identified, and Mozilla's privacy review says it found no known security breaches with Schlage's smart locks or Schlage as a company.
Which Schlage locks need the newest firmware most urgently?
Schlage Control locks manufactured before July 30, 2019, and Schlage Control Mobile Enabled BE467/FE410 locks are the clearest candidates for immediate checking because Allegion published recent releases specifically for those product lines.
Why did my Schlage lock go offline after a security patch?
One documented case linked offline behavior to a recent security patch from a chipset manufacturer, with notes indicating that older Schlage firmware relied on an insecure communication loophole that the patch removed.
Should I roll back a security update if the lock stops working?
Generally no, because rolling back a security patch can reopen the vulnerability the patch was meant to close; one platform response explicitly said it would not roll the patch back because that would create a vulnerability for the hub.
What should I do after updating?
After updating, test keypad entry, app control, relock behavior, and any hub integrations, then confirm the lock reports the correct status across all connected devices.
