This guide will walk you through the process step-by-step, empowering you to handle this common car maintenance issue yourself.
Overview
Replacing a remote car key battery typically involves the following steps:
1. Identifying the Battery Type
The first step is to determine the type of battery used in your remote car key. This information can usually be found in your owner’s manual or by examining the key itself. Common battery types include CR2032, CR2025, and CR1616.

3. Removing the Old Battery
With the key fob open, carefully remove the old battery. It’s typically held in place by a small clip or adhesive. Take note of the battery’s orientation as you remove it, as the new battery must be inserted in the same way.
4. Inserting the New Battery
Insert the new battery into the compartment, ensuring it’s oriented correctly. Press it firmly into place until it clicks or sits securely.
5. Closing the Key Fob
Close the key fob and ensure it snaps shut securely. Test the key fob by pressing the buttons to make sure it’s functioning properly. (See Also: How Do I Test My Car Battery)
