Symptoms
After installing a new metal strike plate the app reports a shut door even while it is slightly open. This guide addresses that particular contrast, not every fault that can occur with the product or service.
- Observable failure: After installing a new metal strike plate the app reports a shut door even while it is slightly open.
- Control test: Compare door sensor response at fully open, half open and shut positions without locking the bolt.
- A confirmed correction must meet this outcome: The open-door indicator changes accurately across physical positions before auto-lock is restored.
Write down the exact sequence that reproduces the failure and the moment it stops. Intermittent failures are easiest to isolate when the same short test is repeated before and after one change.
Why It Happens
A video stream, a cloud acknowledgment and a physical door release represent different subsystems. Access credentials, egress safety and residents' permissions take precedence over convenience changes.
The important distinction is whether magnet field altered by new plate or sensor calibration assumes old alignment explains the observed difference. Door gap changed during hardware service remains another plausible explanation until the comparison rules it out.
Three competing explanations
- Magnet field altered by new plate.
- Sensor calibration assumes old alignment.
- Door gap changed during hardware service.
These are hypotheses. Do not infer a hardware defect, account restriction or network outage from one status indicator alone. A result that supports magnet field altered by new plate does not automatically exclude sensor calibration assumes old alignment; the comparison needs to separate them.
Before Making Changes
Protect legitimate emergency entry and fire egress. Change permissions only through the authorized owner or building administrator. Do not force bolt engagement against a misaligned strike plate.
Preserve the current state: note the affected product or account, current mode and time of the failed attempt. If settings will be changed, photograph or write down their original values. Keep copies of any unique files or evidence before overwriting anything.
Use a non-sensitive sample whenever possible. If the issue involves a shared device, building system, workplace account or regulated equipment, obtain the appropriate owner or administrator permission first. Stop if the test would compromise security, electrical protection, access or an animal's welfare.
Problem-Specific Diagnosis
Run this discriminating test before restarting or resetting the entire system: Compare door sensor response at fully open, half open and shut positions without locking the bolt. Compare the observed result against the three paths below.
| Observation or suspected layer | Interpretation | Next controlled check |
|---|---|---|
| Magnet field altered by new plate | If the failing state changes under the comparison, magnet field altered by new plate is plausible. This is not yet proof. | Repeat with that one factor changed, then return to baseline. |
| Sensor calibration assumes old alignment | If the first change has no effect but a supported configuration differs, sensor calibration assumes old alignment moves higher on the list. | Inspect the relevant option or documented behavior without clearing unrelated settings. |
| Door gap changed during hardware service | If both earlier paths are contradicted, investigate whether door gap changed during hardware service accounts for the timing or device-specific result. | Collect an event timestamp or status report for qualified support. |
Now apply the least-disruptive change that corresponds to the evidence: Temporarily use manual locking, review the installed sensor alignment and compare with original mounting photo. Avoid treating all three hypotheses at once; simultaneous changes erase the diagnostic value of the test.
Step-by-Step Troubleshooting
Begin with reversible comparisons. Use Advanced only if the evidence points to a deeper problem.
Verify the affected workflow
After installing a new metal strike plate the app reports a shut door even while it is slightly open. Write down where it happens, its most recent time and the state displayed by the product. Do not treat a nearby working feature as proof the whole path is healthy.
Run the safe comparison
Compare door sensor response at fully open, half open and shut positions without locking the bolt. Use the same device, account and operating conditions where practical. Note what remains unchanged so the comparison is meaningful.
Try the smallest safe intervention
Temporarily use manual locking, review the installed sensor alignment and compare with original mounting photo. Make one adjustment at a time and preserve the previous value so it can be restored if the result becomes worse.
Confirm the real outcome
The open-door indicator changes accurately across physical positions before auto-lock is restored. Repeat the complete user-facing operation and then make sure unrelated protections and functions still work. If the result is inconsistent, restore the previous setting and continue diagnosis.
Separate the three suspected layers
Assess evidence for magnet field altered by new plate, sensor calibration assumes old alignment and door gap changed during hardware service separately. A positive result for one path is not evidence for every path. Preserve before-and-after observations, including timestamps.
Check the responsible subsystem
Have an authorized locksmith or installer verify magnet placement and the mechanical fit without disabling egress. Gather only logs and supported diagnostic views that apply to this exact scenario; do not change service-wide policy or hardware wiring.
Validate the unaffected path
Revisit the comparison: Compare door sensor response at fully open, half open and shut positions without locking the bolt. If the first suspected cause is not supported, compare the behavior predicted by sensor calibration assumes old alignment with the behavior predicted by door gap changed during hardware service. Keep the first correction reversible.
Commit or escalate with evidence
Confirm: The open-door indicator changes accurately across physical positions before auto-lock is restored. If that cannot be reproduced, restore the original safe configuration and send sanitized observations to the device owner, building manager or access-control service provider. Safety boundary: Do not force bolt engagement against a misaligned strike plate.

Common Mistakes to Avoid
- Assuming magnet field altered by new plate is proven simply because the visible symptom matches this page.
- Changing multiple accounts, rules, connections or device settings before running the control: Compare door sensor response at fully open, half open and shut positions without locking the bolt.
- Skipping this safety boundary: Do not force bolt engagement against a misaligned strike plate.
- Resetting, formatting, deleting credentials or replacing hardware without a confirmed backup, a supported recovery path and evidence that the step is necessary.
A setting that makes one symptom disappear is not always the correct permanent configuration. If it disables another essential function, revert it and investigate the underlying dependency rather than leaving an unsafe workaround in place.
How to Verify the Fix
The primary pass condition is specific: The open-door indicator changes accurately across physical positions before auto-lock is restored. Repeat the original workflow, not a loosely related shortcut, and confirm both the previously failing behavior and an unaffected comparison still work.
- Record the before-and-after state in the same location, account and operating mode.
- Repeat the original comparison: Compare door sensor response at fully open, half open and shut positions without locking the bolt.
- Check the stated pass result: The open-door indicator changes accurately across physical positions before auto-lock is restored.
- Confirm that normal security, notification, storage or physical safety protections remain enabled.
If the result works only once or disappears after reopening the app, reconnecting the accessory or waiting for the next scheduled event, treat the issue as intermittent instead of fixed. Keep the event time and what changed between attempts.
If the Problem Continues
If the safe correction does not work, move to a focused deeper investigation: Have an authorized locksmith or installer verify magnet placement and the mechanical fit without disabling egress. This is a different path from the first settings check; use it only if the device or service supports the required diagnostics.
When escalating to the device owner, building manager or access-control service provider, provide the exact symptom, result of the control test, changes already tried, time of occurrence and any non-sensitive error or status data. Explain whether magnet field altered by new plate, sensor calibration assumes old alignment and door gap changed during hardware service were supported or contradicted by evidence.
Do not share account recovery codes, private documents, live access tokens, sensitive location histories or full recordings merely to prove the problem. Redact or summarize identifiers before opening a public support request.
Prevent Recurrence
Keep a short reference note with the working configuration and the successful check: The open-door indicator changes accurately across physical positions before auto-lock is restored. After an app update, firmware change, network migration or scheduled clock change, run the same short test before depending on the function again.
Watch for the condition that originally made the failure visible: After installing a new metal strike plate the app reports a shut door even while it is slightly open. Where practical, retain an alternative approved way to perform the essential task so that one device, cloud service or interface does not become a single point of failure.
FAQ
How can I tell whether magnet field altered by new plate is responsible?
Run the controlled comparison: Compare door sensor response at fully open, half open and shut positions without locking the bolt. A change that specifically affects the failing layer supports this hypothesis, but repeat it before changing permanent settings.
What if the real cause is sensor calibration assumes old alignment rather than magnet field altered by new plate?
Do not repeat the initial correction blindly. Check the supported diagnostic path: Have an authorized locksmith or installer verify magnet placement and the mechanical fit without disabling egress. Keep the earlier working configuration recorded so you can reverse the test.
When is this particular issue resolved?
The decisive result is: The open-door indicator changes accurately across physical positions before auto-lock is restored. If it fails after the normal workflow is repeated, document whether door gap changed during hardware service still explains the remaining behavior and escalate with non-sensitive observations.
