Avoid Warranty Surprises: 5 Common Reasons Digital Lock Claims Get Rejected (and How to Prevent Them!)

Author
Published on:

Your digital lock is designed to offer convenience and security — but did you know certain mistakes can void your warranty? Here are the top 5 reasons claims often get rejected and how you can easily prevent them.

1. Battery Leakage or Corrosion Damage

Battery leakage is one of the most common causes of lock failure — and it’s not covered under warranty because it’s considered user negligence. Leaked acid can corrode the battery terminals and internal components, permanently damaging the circuit board.

How to Prevent:

  • Always use high-quality alkaline batteries
  • Replace them every 6–9 months or when the low battery indicator appears.
  • Never mix old and new batteries or different brands.

✅ Recommended vs ❌ Not Recommended Batteries

Type Recommended Reason
Alkaline (non-rechargeable) ✅ Yes Stable voltage and leak-resistant design
Lithium ✅ Yes May have higher voltage – check lock manual
Rechargeable (NiMH / NiCd) ❌ No Causes unstable power and leakage risk
Zinc Carbon / Heavy Duty ❌ No Short lifespan, higher leak probability

2. Improper DIY Installation or Unauthorized Servicing

DIY installations may seem simple but can easily lead to misalignment or wire damage. Similarly, unauthorized servicing can void the warranty if tampering is detected.

How to Prevent:

  • Always engage authorized installers.
  • Keep your installation and service receipts as proof of professional work.

3. Environmental Exposure or Misuse

Digital locks aren’t meant to handle extreme weather unless specified. Continuous exposure to rain, humidity, or direct sunlight can cause rust, fading, or internal malfunction — which are not covered under warranty.

How to Prevent:

  • Install the lock under a sheltered entrance.
  • Opt for weather resistant models if it’s exposed to outdoor conditions.

4. Misplacement of Parts or Accessories

Warranty doesn’t cover lost mechanical keys, RFID cards, or remote controls. Misplacing these can also affect your security.

How to Prevent:

  • Keep all backup keys and cards in a safe, labeled location.
  • Store digital lock accessories together for easy access.

5. Partial Warranty Coverage Misunderstanding

Not all lock components share the same coverage period. For instance, some of the main lock body may have 3 years warranty, but accessories or electronic parts could only be covered for 1 year

How to Prevent:

  • Ask your retailer for the detailed warranty breakdown.
  • Clarify what’s covered before confirming your purchase.

Final Tip:

Proper care and awareness can extend the life of your digital lock and keep your warranty valid. Treat your lock like an investment — and it will serve you securely for years to come.
