Frequently Asked Questions

Why need to change the battery in the keyless door lock

You’re probably reading this because you noticed that your keyless door lock is dead and won’t let you in. Don’t worry; it happens to everybody. Keyless door locks are often used outside of a door, exposed to the elements, so their batteries tend to die after a few years (or sooner). This can happen anytime but is more likely to occur during the winter due to colder weather conditions.

If the battery dies on your keyless RFID door lock, you will not be able to open the door. It is essential to replace it as soon as possible because some things could happen if you don’t.

What happens if the battery dies on the keyless door lock

  • The lock may not work at all.
  • You could be locked out of your home or office, which would be inconvenient and potentially dangerous if you had left something valuable inside.
  • This is not a safety device, but it is convenient for people who live alone or have mobility issues in their lives, such as children or elders who cannot reach high shelves or areas where keys are kept in drawers or cabinets above the kitchen sinks.
  • The battery dying on your keyless door lock will not make your house unsafe.
  • The lock still works, but since it has no power supply from its battery anymore, instead of unlocking when I press the button on my remote like usual, I need to push harder until I hear something click somewhere inside that tells me that now it’s unlocked again.

What type of batteries do keyless door locks need

There are two types of batteries that you can use to power your keyless door lock: standard AA batteries and lithium batteries.

  • Standard AA batteries are the most common dry cell type, which does not require any maintenance or special care. They can be used for decades without problems, but they won’t last as long as lithium batteries.
  • Lithium batteries are often used in high-tech devices like cell phones and laptops because they have a longer life span than standard alkaline cells. Lithiums also hold their charge longer than their counterparts and have less self-discharge (meaning they lose power more slowly between uses).

In addition to these advantages, lithiums have lower energy density than alkalines, so they can’t store as much energy per kilogram; however, this isn’t an issue since most devices only require a small amount of current anyway.

The answer to “how long does the battery last in a keyless door lock?” can be a bit complicated. It depends on several factors, including:

The life of a battery depends on the brand, type, usage, and conditions.

  • The brand and type of your keyless door lock. There are many different brands and types of keyless smart door locks, each with varying specifications regarding their batteries. Some have a longer battery life than others. For example, some use AA batteries while others use AAA batteries; some use lithium-ion or alkaline batteries; others use nickel-cadmium or silver oxide batteries.
  • How you use your keyless door lock — whether it’s just used once every few months or if it’s used daily by multiple people (or both). If it’s only being used infrequently, the battery may last longer than if it were being used continuously throughout the day by several people who want access to their home at any given time during those 24 hours.
  • Your device’s environment impacts its potential lifespan, especially temperature extremes! Cold temperatures can kill power faster than hot ones do. So if possible, try keeping them somewhere cool with moderate humidity levels instead – this should help extend their usable lifetime considerably!

The battery of your keyless door lock needs changing if the following occurs:

  • The lock does not work; it does not open or close. The battery is dead and needs to be replaced.
  • The lock beeps when pressing buttons but doesn’t unlock or open the door. Rechargeable batteries lose power over time, so replacing them can restore the full function of your keyless door lock.
  • The lock only opens or unlocks once or twice and then stops working completely.
  • Light indicator: If you have a keyless door lock, you can tell whether the battery needs to be replaced by checking the spare hand. It’s usually located on top of your keyless door lock and will blink when it needs to be changed.

You will need a Phillips screwdriver and a flat one to remove the cover. Sometimes, you may also need a Torx bit or hex wrench, depending on the brand of your lock.

Make sure to have new batteries on hand before changing them out—you can find these at any local hardware store or online.
