Types of Car Key Batteries
Understanding the type of battery your car key uses is crucial before attempting to replace it. There are two primary types commonly found in car keys:
CR2032 Battery
This is the most prevalent type, often used in standard remote-controlled car keys. It’s a small, round coin cell battery with a diameter of 20mm and a thickness of 3.2mm. The CR2032 battery is readily available at most convenience stores, electronics stores, and online retailers.
Identifying a CR2032 Battery
- Small, circular shape.
- Diameter of 20mm and thickness of 3.2mm.
- Often marked with “CR2032” or similar markings.
CR1616 Battery
This battery type is slightly smaller than the CR2032, measuring 16mm in diameter and 1.6mm in thickness. While less common, it can be found in some car key models, particularly older ones or those with slimmer key designs.
Identifying a CR1616 Battery
- Smaller than CR2032.
