Most key fobs have a metal ‘key blade’ inside. Its sole purpose is to unlock the driver’s side door in case the fob battery dies. Take the fob apart and you’ll find the key blade hidden inside.
It’s a good idea to practice taking the key blade out before you’re in a pinch.
Hold the Key Fob Close to the Start Button or Use It to Press the Button
Even with a dead battery, the fob can still send a signal over a short range. Hold the fob right next to the start button. You can also try using the fob to press the button.
Check for a Key Slot
Some cars have a slot somewhere on the steering column to “accept” the key fob and connect its signal to the car.
Each car has a unique key fob design and varying abilities to pick up short-range signals. Refer to your owner’s manual or research your specific car’s start procedure in case your key fob battery dies.
These are some ways to start your car even if your key fob battery runs out, so you can continue your journey uninterrupted.
