How to Replace the Old Batteries in Keyless Door Lock
Performing a door lock battery replacement is an easy task. But you need to have the right tools to help you out. The items mentioned below are easy to find. You can buy them at the nearest hardware store or order them online.
- Screwdriver – The screws securing most of the keyless door locks require a Phillips screwdriver. The basic sizes of a Phillip head screwdriver are #0, #1, #2, #3, and #4. The #1 is commonly used for screws with standard size, while the #2 is used for screws that are miniature or jeweler-size.
- If it turns out that the screw head is slotted, you will need to use a flathead screwdriver, although it may seldomly happen. The standard sizes of a flathead screwdriver are ⅛”, 5/32”, 3/16”, ¼”, 5/16”, and 8/8”.
- New batteries – Batteries needed by locks may vary, so you must know what kind of batteries your lock has. Kwikset and Yale locks are typically powered by AA batteries, while AAA batteries operate Schlage locks. However, sophisticated locks require 9-volt batteries.
Other types of batteries that your lock may need are AAAA batteries, C batteries, and D batteries. Your lock will fail to work if you put the wrong batteries on it, so it is crucial to ensure what kind of batteries your lock requires.
