Critical Safety Precautions:

Secure your Kevo account with a strong, unique password and enable two-factor authentication. Regularly review access logs and revoke permissions for unauthorized users. Do not share your digital key with untrusted individuals. Protect the physical fob from theft or loss. Consider disabling the touch-to-open feature during extended absences.

Step-by-Step Fix:

1

Replace the fob battery with a new, high-quality CR2025 battery. Ensure correct polarity.
2

Verify Bluetooth is enabled on the smartphone linked to the Kevo (if applicable).
3

Use a Wi-Fi analyzer app (e.g., NetSpot) to identify 2.4GHz channel congestion. Consider relocating the router or switching channels.
4

Reprogram the fob to the lock following the Weiser Kevo programming instructions. Factory reset may be necessary.
5

Inspect the door frame and strike plate for any signs of warping or misalignment. Adjust the strike plate as needed to ensure smooth bolt operation.
6

Test the fob's proximity range in multiple locations around the door to rule out localized RF dead zones.
7

Check firmware. Update to the latest available firmware through the Weiser app.

What to Look For:

Intermittent or complete failure of the Weiser Kevo fob to unlock the door. Observed behaviour includes flashing red LED on the lock body upon fob proximity, no response from the touch sensor, and error message 'Fob Not Detected' within the Weiser app (if paired).

Common Causes:

Weak fob battery (CR2025 typically). Cold weather significantly reduces battery performance.
RF interference from other 2.4GHz devices (Wi-Fi routers, microwave ovens, cordless phones).
Physical obstruction between the fob and the lock (e.g., metal doors, thick walls).
Incorrect fob pairing or corrupted lock credentials requiring re-initialization.
Internal hardware failure within the fob's Bluetooth transmitter circuit.
Door frame misalignment causing mechanical stress on the locking mechanism, impacting signal reception.

Expert Tip:

If the fob is still not detected after battery replacement, try the three-tap reset sequence on the interior lock housing. Remove the battery cover and locate the programming button. Press the button three times rapidly, then attempt to re-pair the fob. This can clear temporary glitches in the lock's memory.

Technical Overview:

The Weiser Kevo relies on Bluetooth Low Energy (BLE) for fob communication. The fob transmits a unique encrypted identifier. The lock validates this ID against its stored credentials. Signal attenuation can occur due to RF interference on the 2.4GHz band, weakened fob battery voltage, or physical obstructions. Power consumption profiles fluctuate significantly during Canadian winter months due to battery impedance increases at low temperatures.

Prevention:

Replace the fob battery annually, preferably before the onset of winter. Use lithium batteries for better cold-weather performance.
Regularly inspect the door frame and strike plate for signs of wear or misalignment.
Periodically check for firmware updates through the Weiser app.
Minimize 2.4 GHz interference.
Consider a backup physical key.
