Understanding Your Honda City Car Key
Before diving into the battery replacement process, it’s essential to understand the different types of Honda City car keys and their components. Honda City models typically use either traditional key fobs or smart keys, each with its own unique design and battery requirements.
Traditional Key Fobs
Traditional key fobs are the more common type, featuring a physical key blade and a separate button panel for locking, unlocking, and trunk release. These key fobs typically use a CR2032 battery, a small, coin-shaped lithium battery readily available at most stores.
Smart Keys
Smart keys, also known as proximity keys, are more advanced and often found in newer Honda City models. They don’t have a separate key blade; instead, they use radio frequency identification (RFID) technology to communicate with the vehicle. Smart keys typically use a CR2016 or CR2025 battery, which is slightly smaller than the CR2032 battery used in traditional key fobs.
Tools You’ll Need
Gathering the necessary tools before you begin is crucial for a smooth and successful battery replacement. Here’s what you’ll need:
- A new car key battery (CR2032 or CR2016/2025, depending on your key type)
- A small flathead screwdriver or a key fob battery removal tool
- A small piece of tape (optional, for securing the battery contacts)

1. Identify the Battery Compartment
Locate the small compartment on the back of your key fob that houses the battery. This compartment is usually secured by a small screw or a sliding cover.
2. Open the Battery Compartment
Using your screwdriver or key fob battery removal tool, carefully pry open the battery compartment. Be gentle to avoid damaging the key fob’s plastic casing.
3. Remove the Old Battery
Once the compartment is open, gently lift out the old battery. Note the positive (+) and negative (-) terminals on both the old and new batteries to ensure proper installation.
4. Install the New Battery
Align the positive (+) and negative (-) terminals of the new battery with the corresponding contacts in the key fob compartment. Gently press the new battery into place until it sits securely.
5. Close the Battery Compartment
Carefully slide the cover back into place or tighten the screw to secure the battery compartment.
6. Test Your Key Fob

Troubleshooting Common Issues
While changing a car key battery is generally straightforward, you might encounter some common issues. Here are a few troubleshooting tips:
