Backup Power Solutions: A Guide for Smart Door Locks

Why Do You Need Backup Power?

Power outages can be unpredictable and often occur during emergency situations such as severe weather conditions or natural disasters. Without electricity, many household appliances including smart door locks will not work until the electrical grid is restored. If you rely solely on a battery-powered smart lock without backup power options in place, you may be locked out of your home when you need access most.

Types of Backup Power Solutions

There are several types of backup power solutions available that can help ensure uninterrupted operation of your smart door lock during a power outage:

Battery Backup Option

A battery backup option is one commonly used solution for maintaining access to your home through a smart lock during an outage. This solution involves using rechargeable batteries that are installed alongside the existing batteries in the device. When there is a loss of electrical supply from the main source (grid), these replaceable batteries activate automatically ensuring continuous performance without interruption.


  • Low cost
  • Easy to install
  • Can last up to 6 months between charges depending on ​the manufacturer’s specifications.


  • Battery life reduces over time (lower longevity)
  • The additional hardware required can lead vandalism ore destruction

Solar-Powered Backups

Solar-powered backups utilize solar panels installed near doors where light exposure is maximal so they serve two functions at once ― powering up security cameras as well as offering backup power for smart locks.


  • No dependency on the electrical grid
  • Infinite energy provided there is adequate sunlight
  • Environmentally friendly
  • Low maintenance cost required


  • More expensive than battery-powered backups
  • May not be suitable for locations without sufficient exposure to sunlight

Generator Backup Option

A generator can provide reliable backup power in case of extended outages, particularly when you have a high-energy consuming smart lock system such as one with biometric sensors or facial recognition features.


  • Provides longer runtime.
  • Ideal option for areas that frequently experience power outages


  • Higher upfront costs
  • Requires special installation requirements and professional assistance

Choosing the Right Backup Solution

When selecting a backup solution for your smart door lock, it’s crucial to consider factors like duration of the outage, location of your home, budget and unique features necessary. Evaluate each type by looking at:

1) Reliability: Choose a solution that guarantees consistent access to your doors despite any obstacles presented by natural disasters.

2) Accessibility: Make sure you choose an option that ensures people who need frequent access will find easy usage even during an outage.

3) Cost-effectiveness: analyze different options weighing up their pros and cons against what fits best into your budget

By understanding these considerations about some types of backup solutions available for smart door locks, homeowners can rest assured they will never be locked out again regardless of weather condition or emergency circumstances.


Sure, here are three popular FAQs with answers for “Backup Power Solutions: A Guide for Smart Door Locks”:

Q: What is a backup power solution for smart door locks?
A: A backup power solution is a means of providing emergency power to your smart door lock when the primary power source (such as batteries or electrical wiring) fails. Backup power can come in various forms, such as portable battery packs, rechargeable batteries, and solar panels.

Q: Do all smart door locks require a backup power solution?
A: It depends on the type of smart door lock you have and how it is powered. Some models are designed to operate without external electrical sources and do not require backups; others rely solely on batteries or wired connections that may need backups in case of outages or malfunctions.

Q: How long does backup power typically last for a smart door lock?
A: The duration of backup power varies depending on factors such as the type of device, its energy consumption rate, and the capacity of the backup source being used. In general, high-capacity battery packs can keep most smart locks powered for several hours to several days; solar-powered options generally provide continuous charging capability but may be less reliable during extended periods of low light conditions like bad weather or indoors with little sunlight exposure.

Hopefully these answers help provide some clarity about using backup solutions with your smart locks!
