Key fobs are convenient devices that allow us to lock and unlock our cars, open our trunks, and even start our engines—all without having to take out our keys. But what happens when the battery in your key fob dies? You won't be able to use it to access your car, which can be a major inconvenience.

Locate the key fob's battery compartment.
The battery compartment for your key fob can usually be found in one of three places:
- Inside the key fob itself: This is the most common location for the battery compartment. To open the key fob, you may need to use a small screwdriver to pry open the casing. Be careful not to damage the key fob while doing this.
- On the back of the key fob: Some key fobs have a small door on the back that can be opened to reveal the battery compartment. To open the door, you may need to use a small screwdriver or your fingernail.
- Inside the car: In some cases, the key fob's battery compartment is located inside the car. This is usually the case for cars that have a keyless ignition system. To find the battery compartment, consult your car's owner's manual.
Once you have found the battery compartment, you will need to open it. This can usually be done by sliding a small screwdriver or your fingernail into the slot next to the compartment and prying it open.
Once the battery compartment is open, you will see the old battery. Remove the old battery by carefully prying it out with a small screwdriver or your fingernail.
Now you are ready to insert the new battery. Be sure to insert the new battery in the correct orientation. The positive (+) terminal of the battery should be facing up.
Once the new battery is inserted, close the battery compartment and test the key fob to make sure it is working properly.
Open the battery compartment.
Once you have located the battery compartment on your key fob, you need to open it. The method for opening the battery compartment will vary depending on the make and model of your car.
Here are some general tips for opening the battery compartment:
- Look for a small slot or indentation on the key fob. This is usually located near the battery compartment. Insert a small screwdriver or your fingernail into the slot and pry open the compartment.
- If there is no slot or indentation, try sliding the two halves of the key fob apart. Some key fobs are designed to be opened this way.
- If the key fob has a screw, remove the screw to open the battery compartment. A small Phillips head screwdriver is usually required for this.
- If you are still having trouble opening the battery compartment, consult your car's owner's manual.
