When it comes to replacing the battery in my car key fob, I’ve learned that choosing the right CR1620 battery is essential for reliable performance. Here’s what I consider before making a purchase, based on my own experience:
Understanding the CR1620 Battery
The CR1620 is a 3V lithium coin cell battery commonly used in small electronics like car key fobs, watches, and calculators. The “16” refers to the battery’s diameter in millimeters (16mm), and “20” is the thickness (2.0mm). Knowing these specs helped me ensure compatibility with my key fob.

- Brand Reputation: I prefer buying from trusted brands like Panasonic, Energizer, or Sony because they tend to last longer and have consistent quality.
- Shelf Life: A long shelf life (usually 5-10 years) means the battery will stay fresh until I use it. I look for batteries with recent manufacturing dates.
- Price vs. Quality: While cheaper batteries are tempting, I’ve learned that investing a bit more upfront saves me from frequent replacements.
- Quantity Packs: Buying multi-packs can be cost-effective since I keep spare batteries on hand for future replacements.
How I Replace My Car Key Fob Battery
Replacing my CR1620 battery is pretty straightforward. I use a small screwdriver or a coin to open the fob’s battery compartment carefully. I pay attention to the battery’s orientation (positive and negative sides) and make sure the new one fits snugly before closing the compartment.
