CR2032 and CR2025 are the two most common key fob batteries. Here’s what you need to know about each.
The Basics
Both batteries are 3-volt lithium coin cells with the same 20mm diameter. The difference is thickness.
| Battery | Diameter | Thickness | Capacity |
|---|---|---|---|
| CR2032 | 20mm | 3.2mm | 220-240 mAh |
| CR2025 | 20mm | 2.5mm | 150-170 mAh |
Can You Substitute One for the Other?
Generally, no.
- A CR2025 might physically fit in a CR2032 slot, but it may not make proper contact
- A CR2032 is too thick for a CR2025 slot and won’t fit
Always use the battery type specified for your key fob.
