My Quick Take

What I Looked For Before Buying
I made sure to check a few things before purchasing:

- A trusted brand with good shelf life
- Fresh packaging and an expiration date far enough out
- A value pack if I wanted extras for future replacements

Signs It’s Time to Replace It
I knew it was time to buy a new battery when:
- The key fob worked only at close range
- The buttons felt unresponsive
- The car displayed a low key battery warning
- I had to press buttons multiple times
Easy Replacement Tip
