Starting your Prius with a dead key fob can be a frustrating experience. This guide provides several methods to get your Prius back on the road, even if your key fob battery has given up the ghost. We’ll cover everything from simple workarounds to more advanced solutions.
Understanding Your Prius Key Fob
Your Prius key fob uses a small battery to power its wireless functions, including locking/unlocking doors and remotely starting the engine. When the battery dies, these functions won’t work. However, your Prius has built-in features that allow you to start the car even with a dead fob. Knowing how these systems work is crucial to getting your car started.
How Does a Dead Fob Affect Starting?
A dead key fob doesn’t completely disable your Prius. The car utilizes a proximity system that detects the fob’s presence even if the battery is dead. This system allows you to unlock the car and start the engine using a backup method. You can often find instructions in your owner’s manual on how to start your car with a dead key fob. These instructions typically involve placing the fob near a specific location in the car, like the start button or the steering column.

Methods to Start Prius with Dead Fob
There are a few different ways to start your Prius when the key fob battery dies. Here’s a step-by-step guide for each method:
- Using the Key Fob’s Hidden Key: Most Prius key fobs have a hidden mechanical key. Remove this key from the fob. Use it to unlock the driver’s side door. Once inside, locate the designated key fob sensor area, usually near the start button or steering column. Place the dead key fob against this sensor. Then, press the start button as you normally would.
- Starting with the Metal Key (No Fob): If you have somehow lost your key fob or if it is damaged beyond repair, some Prius models can be started using the hidden metal key alone. Insert the metal key directly into the ignition cylinder, often hidden beneath a plastic cover near the steering column. This will allow you to start the engine like a traditional car.

- Jump Starting with a Dead 12V Battery: If your Prius 12V battery is also dead, you’ll need to jump-start it first. Once the 12V battery has enough power, you can try the methods above to start the car with the dead fob.

What if None of These Methods Work?
If you’ve tried all the above and your Prius still won’t start, it’s time to seek professional help. A qualified automotive technician can diagnose the problem and provide the necessary repairs. They can also check for dead battery cell symptoms in your 12V battery or other potential issues. Sometimes the issue might not be related to the key fob at all but a different electrical problem.
