If your 2018 GMC key fob is acting up – locking and unlocking erratically, failing to start your vehicle, or simply not responding – a dead battery is often the culprit. Thankfully, replacing the battery in your GMC key fob is a quick and straightforward process that can be done at home with just a few tools.
This comprehensive guide will walk you through everything you need to know about changing your 2018 GMC key fob battery, from identifying the correct replacement battery to troubleshooting common issues.
What You’ll Need for a 2018 GMC Key Fob Battery Change
Before you begin, gather the following items:
- A fresh CR2032 battery: This is the most common type of battery used in GMC key fobs.
- A small flathead screwdriver or a plastic pry tool: This will help you to separate the key fob casing without causing any damage.
- Optional: A small tray or container: This can help you keep track of the small parts as you disassemble the key fob.
Step-by-Step Guide to Changing Your 2018 GMC Key Fob Battery
Follow these simple steps to replace your 2018 GMC key fob battery:
-
Locate the release button: Examine your key fob and find the small release button or notch. This is usually located on the back or side of the fob.
-
Release the key blade: Press the release button and gently slide out the metal key blade from the fob.
-
Separate the key fob casing: Use your flathead screwdriver or plastic pry tool to carefully pry open the key fob casing. Start at the notch where the key blade was inserted and work your way around the edges. Be gentle to avoid damaging the casing or internal components.
-
Identify and remove the old battery: Once the casing is open, you should see the CR2032 battery. Carefully remove the old battery by prying it up from the positive (+) side.
-
Install the new battery: Insert the new CR2032 battery into the slot, making sure the positive (+) side is facing up.
-
Reassemble the key fob: Carefully align the two halves of the key fob casing and press them together firmly until you hear a click, indicating that it’s securely closed.
-
Reinsert the key blade: Slide the metal key blade back into the slot on the key fob.
-
Test the key fob: Try locking and unlocking your vehicle’s doors and starting the engine to ensure the new battery is working correctly.
Troubleshooting Common Issues
If your key fob still isn’t working after replacing the battery, there could be other issues at play. Here are a few things to check:
- Battery installation: Double-check that the new battery is installed correctly with the positive (+) side facing up.
- Key Fob Programming: In some cases, you may need to reprogram your key fob after replacing the battery. Refer to your owner’s manual or contact a qualified locksmith or dealership for assistance.
- Other key fob problems: If you’re still experiencing issues, there could be a problem with the key fob itself, such as a malfunctioning button or damaged internal components.
