Key fobs are convenient devices that allow you to remotely lock, unlock, and start your car without having to fumble with traditional keys. However, like all electronic devices, the batteries in key fobs will eventually run out of power and need to be replaced. In this article, we will provide you with a step-by-step guide on how to change a key fob battery.
Step 1: Identify the Type of Key Fob
The first step in changing a key fob battery is to identify the type of key fob you have. There are two types of key fobs: one-piece and two-piece. One-piece key fobs have a built-in key, while two-piece key fobs have a separate key that can be removed. Knowing the type of key fob you have is important because the battery replacement process will differ depending on the type of key fob.
One-Piece Key Fobs
For one-piece key fobs, locate the small slot on the side of the key fob. Insert a small screwdriver or key into the slot and twist gently to pry open the key fob. Be careful not to apply too much force or you may damage the key fob. Once the key fob is open, you will be able to see the battery.
Two-Piece Key Fobs
For two-piece key fobs, locate the button on the back of the key fob that releases the key. Press the button and remove the key. Once the key is removed, you will be able to see the battery compartment.
Step 2: Remove the Battery
Once you have located the battery compartment, use a small flathead screwdriver to gently pry the battery out of the key fob. Be careful not to damage the battery or the contacts in the battery compartment. If the battery is stuck, try wiggling it back and forth until it comes loose.
Step 3: Install the New Battery
Once the old battery has been removed, insert the new battery into the battery compartment. Make sure the battery is inserted correctly and the contacts are making good contact. If the battery is not inserted correctly, the key fob may not work properly.
Step 4: Test the Key Fob
After installing the new battery, test the key fob to make sure it is working properly. Press the buttons on the key fob to lock and unlock the doors and start the car. If the key fob is not working properly, double-check that the battery is inserted correctly and the contacts are making good contact.
Step 5: Reassemble the Key Fob
Once you have confirmed that the key fob is working properly, reassemble the key fob. For one-piece key fobs, simply snap the two halves of the key fob back together. For two-piece key fobs, insert the key back into the key fob and press the button to lock it in place.
Conclusion
Changing a key fob battery is a simple process that can be done in just a few minutes. By following these simple steps, you can save yourself the time and expense of taking your key fob to a dealership or locksmith to have the battery replaced.
Remember to always use the correct battery type and to insert the battery correctly to ensure proper operation of your key fob. With a little bit of patience and care, you can keep your key fob working like new for years to come.
