When it comes to car key fobs, one of the most overlooked yet crucial components is the battery. Without a functioning battery, your key fob won’t work, leaving you locked out of your vehicle or unable to start your car. Thankfully, replacing your car key battery is a simple task, and it’s essential to stay on top of this maintenance to ensure your key fob continues working reliably.

Car key batteries are typically small coin-cell batteries, like CR2032 or CR2025, depending on the model of your key fob. These batteries can last anywhere from one to three years, but their longevity depends on factors like usage frequency and the quality of the battery. Signs that your car key battery might be running low include a weakened signal, difficulty unlocking the car from a distance, or the car failing to start with the key fob.

Replacing your car key battery is easy and can often be done at home. Most key fobs have a simple casing that can be opened with a small screwdriver.
