How to Change Battery in 2018 Chevy Key Fob

If you own a 2018 Chevy vehicle, chances are you use a key fob to lock, unlock, and start your car. Like all key fobs, the battery in your 2018 Chevy key fob will eventually die, requiring a replacement. Fortunately, changing the battery in your 2018 Chevy key fob is a simple process that you can do yourself in minutes without any special tools or technical expertise. This article provides a step-by-step guide on how to change the battery in your 2018 Chevy key fob, helping you get back on the road quickly and easily.

Understanding Your 2018 Chevy Key Fob

Before you begin, it’s helpful to understand the two types of key fobs that may come with your 2018 Chevy vehicle:

• Standard Key Fob: This type features a traditional key blade that folds into the fob.
• Keyless Entry Remote: This type may not have a visible key blade and relies solely on wireless signals.

Both types require a small, flat battery to power their functions.

Signs You Need to Replace Your Key Fob Battery

Identifying a dying key fob battery early can prevent inconvenient lockouts. Here are some common signs:

• Decreased Range: You need to be closer to your vehicle for the fob to work.
• Intermittent Functioning: The lock, unlock, or panic buttons work sporadically.
• Dashboard Warning Light: Some vehicles display a “Key Fob Battery Low” warning on the dashboard.

Gathering the Necessary Tools

You’ll only need a few things to change your 2018 Chevy key fob battery:

• Replacement Battery: The most common battery type is a CR2032 3V lithium coin battery, easily found at most stores.
• Small Flat-Head Screwdriver: This will help you to pry open the key fob casing carefully.

Step-by-Step Guide to Changing the Battery

Follow these easy steps to replace your 2018 Chevy key fob battery:

1. Locate the Release Button: Most 2018 Chevy key fobs have a small release button or switch. This is usually located on the back or side of the fob.
2. Release the Key Blade (if applicable): If your key fob has a physical key blade, press the release button and carefully slide the blade out of the fob.
3. Separate the Fob Halves: Use your fingernail or the edge of the flat-head screwdriver to carefully pry open the key fob casing along the designated seam. You might hear a slight click when the halves separate.
4. Remove the Old Battery: The CR2032 battery will be clearly visible. Gently pry it out using the screwdriver or your fingernail. Avoid touching the battery’s flat surfaces to prevent transferring oils that might shorten its lifespan.
5. Insert the New Battery: Align the positive (+) side of the new battery facing upwards, matching the orientation of the old battery. Press it firmly into place.
6. Reassemble the Fob: Carefully align the fob halves and press them together until you hear a click, indicating they are securely closed.
7. Reinsert the Key Blade (if applicable): Slide the key blade back into its slot until it locks into place.
8. Test the Key Fob: Try locking and unlocking your car doors and using other fob functions to ensure the new battery works correctly.
