Locating the key fob
Locating the key fob in your 2021 GMC Sierra is the first step to changing the battery. The key fob is a small, handheld device that is used to lock, unlock, and start your vehicle. It is essential to know where the key fob is located before beginning the battery replacement process.
Typically, the key fob can be found in the glove compartment, center console, or a designated storage compartment in the vehicle. If you are unable to locate the key fob, referring to your vehicle’s owner’s manual can provide guidance on its exact location.
Once you have located the key fob, you can proceed with opening it to access the old battery for replacement.
Opening the key fob
When it comes to opening the key fob of your 2021 GMC Sierra, it’s important to be cautious and gentle in order to avoid damaging any components. Start by finding the small slot on the side of the key fob. This slot is designed for prying the key fob open, so use a flathead screwdriver or a coin to carefully insert into the slot. Gently twist the tool to pop the key fob open, being careful not to use too much force.
Once the key fob is open, take note of any small screws or clips that may be holding the key fob together. Use a small screwdriver to carefully remove any screws, and gently unclip any fasteners. It’s important to keep track of these small components to ensure they can be properly reattached during reassembly.
After the key fob is open and any screws or clips are removed, you can now proceed with the task that required opening the key fob, whether it’s replacing the battery or addressing another issue. Be sure to work on a clean, flat surface to prevent losing any small components, and exercise caution to avoid damaging any delicate electronic parts within the key fob.
Removing the old battery
When it comes to maintaining your 2021 GMC Sierra key fob, replacing the old battery is an essential step to ensure it continues to function properly. To begin the process, you will need to locate the small indentation on the side of the key fob, which is used to open the device and access the battery compartment.
Once you have located the indentation, use a small flathead screwdriver or a coin to gently pry open the key fob. Be careful not to apply too much force, as you do not want to damage the casing of the device. Once the key fob is open, you will see the old battery, which can be easily removed by gently popping it out with the screwdriver or your fingers.
After removing the old battery, take note of the type and size of the battery so that you can purchase the correct replacement. It is important to properly dispose of the old battery, as they can be harmful to the environment if not recycled or disposed of properly. Now that the old battery has been removed, you are ready to proceed with replacing it with a new one.
Replacing with a new battery
When it comes time to replace the battery in your 2021 GMC Sierra key fob, you’ll want to make sure you have the right tools and know the proper steps to do so. First, you’ll need to gather a small flathead screwdriver and a new CR2032 battery. Once you have these supplies ready, you can begin the process of opening the key fob to access the old battery.
Next, insert the screwdriver into the notch on the key fob and gently twist to separate the two halves of the fob. Be careful not to use too much force, as you don’t want to damage the fob during this process. Once the fob is opened, you can see the old battery lodged inside.
Now, carefully remove the old battery from its placement and dispose of it properly. Once the old battery is out, you can place the new CR2032 battery into the key fob and align it according to the polarity shown.
Testing the key fob
After successfully replacing the old battery in your 2021 GMC Sierra key fob, it’s important to test if the new battery is working properly. Testing the key fob will ensure that you won’t encounter any issues when trying to lock or unlock your vehicle.
First, make sure that the battery is installed correctly in the key fob. Once you’ve confirmed this, press the buttons on the key fob to check if they are responsive. If the buttons are working as they should, it means that the new battery is functioning properly.
If you notice that the buttons are not responding, it may indicate that the new battery is not making proper contact. In this case, you may need to reinsert the battery or seek the assistance of a professional to ensure that the key fob is in working condition.
