Common Causes of a Dead Key Fob and Quick Fixes

- Key Fob Programming Issues: Sometimes, the connection between your key fob and the car’s system can become disrupted. Reprogramming the key fob may be necessary.

How to Start Your Car with a Dead Key Fob
Several methods can help you get your car started, even with a lifeless key fob. Here’s a step-by-step guide to some effective techniques:
-
Check Your Car’s Manual: Your owner’s manual will likely have specific instructions for starting your car with a dead key fob. This is always the best place to start.

Using the Physical Key: Many key fobs contain a hidden physical key. Use this key to unlock the driver’s side door. This might disable the alarm system and allow you to proceed.
-
Finding the Key Fob Sensor: Some cars have a designated spot, often near the steering column or in the center console, where you can place your key fob to start the car. Check your manual for the exact location.
-
Using the Key Fob to Touch the Start Button: Even with a dead battery, the key fob might still have enough residual power to activate the push-button start. Hold the key fob directly against the start button and try starting the car.
