How to Start Your Chrysler with a Dead Key Fob Battery

Getting your Chrysler started with a dead key fob battery depends on the model and year of your vehicle. Here are some common methods:

Using the Physical Key: Most Chrysler key fobs contain a hidden physical key. Locate the key release button on your fob and use the physical key to unlock the driver’s side door manually. This may also disarm the alarm system.
Passive Entry System: Some Chrysler models have a passive entry system that allows you to start the car even with a dead key fob battery. Look for a designated spot on the steering column or dashboard where you can place the key fob to start the engine. Consult your owner’s manual for the precise location.
Jumpstarting the Key Fob (Specific Models): Certain Chrysler models may allow you to jumpstart the key fob using the car battery. This method is usually model-specific and involves touching the key fob to designated contacts within the vehicle.
