You’re cruising down the highway, windows down, music blasting – life is good. You pull up to your destination, reach for your key fob to lock your car, and… nothing. Dead battery.
We’ve all been there. A dead key fob battery is a modern-day inconvenience we could all do without. But how long should a key fob battery last? And how can you tell when it’s about to die?
Let’s unlock the answers.
Key Fob Battery Lifespan: What to Expect
The lifespan of your key fob battery can vary depending on a few factors:
- Type of Battery: Most key fobs use a standard CR2032 battery, a small, coin-shaped lithium battery.
- Frequency of Use: Like any battery, the more you use your key fob, the quicker it will drain.
- Signal Strength: If your car is parked further away, the key fob has to work harder to transmit a signal, which can deplete the battery faster.
- Environmental Factors: Extreme temperatures, both hot and cold, can affect battery performance.
Generally speaking, you can expect a key fob battery to last anywhere from 3 to 5 years. However, it’s always a good idea to be aware of the signs of a dying battery.
Warning Signs Your Key Fob Battery is Dying
Don’t get caught off guard by a dead key fob battery. Here are a few telltale signs that it’s time for a replacement:
- Decreased Range: Do you find yourself standing closer to your car to lock or unlock it? This is often the first sign of a weakening battery.
- Intermittent Functioning: If your key fob works sporadically – sometimes it works, sometimes it doesn’t – it’s a strong indicator that the battery is on its last legs.
- Dashboard Warning Light: Some newer cars have a dashboard warning light that specifically indicates a low key fob battery.
- Physical Inspection: If you open the key fob and notice corrosion or leakage on the battery, it’s definitely time for a new one.
Replacing Your Key Fob Battery: A Quick and Easy Fix
The good news is that replacing your key fob battery is usually a simple DIY task that can save you a trip to the dealership.
