All About Smart Door Lock Batteries

Battery Replacement, Equipment

Wondering how to keep your smart door lock powered and reliable? This guide covers everything you need to know about smart lock batteries, from lifespan to replacement tips.

Why isn’t my door lock’s battery state updating?

If you’ve changed the batteries for your smart door lock and the battery status isn’t updating, there could be a few different reasons:

  • First, verify you’re using the recommended batteries. Guardian recommends name brand such as Energizer, Duracell, or Panasonic alkaline batteries.
  • Ensure the batteries have not reached their expiration date. 
  • Lock and unlock your door manually. This will force an update to the system and our interactive services.

Why do my smart lock batteries drain so quickly?

If your door lock’s batteries drain too quickly, there could be a few different reasons:

  • First, verify you’re using the recommended batteries. Guardian recommends name brand such as Energizer, Duracell, or Panasonic alkaline batteries.
  • Ensure the batteries have not reached their expiration date. 
  • The door lock motor may be overworked. To verify: 

1. Open the door and lock the door lock. The dead bolt should fully extend with little resistance. Unlock the mechanism and close the door tightly. 

2. Lock the door again. Check to ensure the lock mechanism is in the same orientation as earlier. You should not have resistance when locking the door here. If you encounter resistance, the door lock motor is being overworked and causing the batteries to drain faster. Contact us at 1.800.PROTECT (1.800.776.8328) to schedule a technician to assist with adjusting your lock.
