Understanding Keyless Entry and Start Systems

Modern cars often utilize keyless entry and start systems, adding convenience to our daily commutes. These systems rely on a small battery inside the key fob to transmit a radio signal to the car’s receiver. This signal unlocks the doors and allows you to start the engine without physically inserting a key. But what happens when that battery dies?

What Happens When the Key Fob Battery Dies?

When your key fob battery dies, the radio signal is no longer transmitted. This means the car won’t recognize the key fob remotely. However, most modern vehicles have backup systems in place to allow you to still access and start your car.

How to Start Your Car with a Dead Key Fob Battery

Even with a dead key fob battery, you should still be able to start your car. Most cars have a hidden key blade inside the key fob. This key can be used to manually unlock the driver’s side door. Once inside, look for a designated spot, often near the steering column or inside the center console, where you can place the key fob. This spot usually contains a backup sensor that will allow the car to detect the key fob even with a dead battery. Once the key fob is in place, you should be able to start the car normally.

Can I Drive With a Dead Key Fob Battery?

Yes, you can generally drive with a dead key fob battery once you have started the car using the backup method. However, keep in mind that you will need to repeat this process every time you start the car until you replace the battery in the key fob.

How to Change Your Key Fob Battery

Changing your key fob battery is a simple process that can usually be done at home. You will need a small screwdriver and a replacement battery, which you can find at most hardware or auto parts stores. Refer to your owner’s manual for specific instructions for your car model. 07 prius key fob battery
