Starting your car when the key fob is dead can be a simple process if you know the right steps. Most modern vehicles have built-in systems that allow you to start the car even if the key fob battery is depleted. Here’s how you can do it:
How to Start Your Car with a Dead Key Fob
-
Use the Backup Key: Many key fobs contain a mechanical key inside. Look for a small release button on the fob to slide out the key. Use this to unlock the driver’s door manually.
-
Push-Button Start Vehicles: If your car has a push-button start, hold the dead key fob close to the start button or a designated area (often indicated in the owner’s manual). Press the start button while holding the fob in place.
-
Insert Key Fob into Ignition Slot: Some vehicles have a slot where you can insert the key fob. This slot is often located on the dashboard or center console. Insert the fob and press the start button or turn the ignition as usual.
-
Replace the Key Fob Battery: If possible, replace the battery in the key fob. This is a simple process that can often be done with a small screwdriver.
Why Does a Key Fob Battery Die?
Key fob batteries die due to regular use and exposure to extreme temperatures. Over time, the battery’s power diminishes, leading to a dead key fob. Regularly replacing the battery can prevent unexpected failures.
