These symptoms highlight various ways a dying battery can impact your key fob’s functionality. Understandably, some people might disagree on the urgency of replacing a key fob battery based on their individual experiences.

1. Reduced Range When Using the Fob:
   Reduced range occurs when the battery voltage drops below the required level. A healthy key fob should unlock your vehicle from at least 30 feet away. If you notice that you need to be much closer to the vehicle for it to respond, it may signal a weak battery.

2. Inconsistent Response When Pressing Buttons:
   Inconsistent responses can manifest as delayed or absent reactions when you press the key fob buttons. This can be frustrating, as it affects convenience and might require multiple attempts for a simple unlock. Many users report this problem as one of the early signs of battery depletion.

3. Warning Light on the Dashboard Indicating a Key Fob Issue:
   A warning light appearing on the dashboard signifies that the vehicle is detecting key fob malfunctions. This usually occurs as the battery weakens and the fob fails to communicate effectively with the vehicle. If you ignore this warning, it could lead to complete key fob failure.

4. Key Fob Not Working at All:
   If the key fob ceases to function completely, it is often an indicator of a dead or ineffective battery. Upon replacing the battery, the fob typically resumes normal operation, demonstrating the importance of promptly addressing this issue.

5. Physical Signs Like a Swollen or Corroded Battery:
   Physical inspection of the battery may show signs of corrosion or swelling. These can occur due to battery leakage or age, impacting overall function. It’s crucial to replace such batteries immediately to avoid potential damage to the fob.

Identifying these signs early helps maintain the convenience of using your Chevy Suburban key fob.
