Common Causes of Dead Key Fob Batteries

Methods to Start Your Cadillac STS with a Dead Key Fob

Here are some proven methods to start your Cadillac STS when your key fob battery is dead:

Using the Hidden Key: Many Cadillac STS key fobs have a hidden mechanical key inside. This key can be used to unlock the driver’s side door manually and often to start the car as well. Check your owner’s manual for the specific location of this key and how to use it to start the ignition.
Jumpstarting the Key Fob (Specific Models): Some Cadillac STS models allow you to jumpstart the key fob by touching it to a specific point in the car, usually near the start button. This can provide enough power to send the start signal to the car. Consult your owner’s manual to see if your model supports this feature.
