Updated over 3 weeks ago

Quick Checklist (Do This First)

  1. Check usage patterns: Frequent remote operations, Wi-Fi activity, or repeated biometric scans can increase power consumption.

  2. Disable high-power features temporarily: Verify ECO settings in the app.

  3. Confirm Wi-Fi band and signal: Ensure the lock is connected to a stable 2.4 GHz network.

  4. Inspect the active battery: Remove it from the lock and check for bloating, corrosion, or loose contacts.

  5. Insert the spare battery: Place a fully charged spare battery in the lock.

  6. Check battery contacts and orientation: Make sure the battery is inserted correctly and contacts are clean.


Test Results

  • If the issue occurs with only one battery:

    • That battery is faulty and needs replacement.

    • Check the warranty status:

      • Within 1-year warranty: Order a replacement via KB article “Create a Sales Order.”

      • Beyond 1-year warranty: Direct the customer to MSL Replacement Parts: MSL Spare Parts


  • If the issue persists with both sufficiently charged batteries:

    1. Perform a factory reset.

    2. If the reset does not resolve the issue, inspect cables and pins:

      • Ensure the cable joint is properly inserted and not reversed.

      • Check that the pin header in the cable joint is not bent or loose.

      • Confirm the cable is not crushed, broken, or distorted during installation.

Note:

  • Issues caused by bent/loose pins or damaged cables from improper installation are not covered under warranty.

  • Damaged outside panel cable: Customer needs a replacement outside panel.

  • Loose/bent pins in inside panel: Customer needs a replacement inside panel.

  • Refer customers to MSL Replacement Parts: MSL Spare Parts

  • If no cable/pin damage is found and the issue occurs with both batteries:

    • Proceed with replacing the inside panel following the Tech Escalation process.
