Experiencing issues with your 2001 PT Cruiser key fob? You’re not alone. A common question revolves around battery types and their impact on signal strength, especially when considering aftermarket options. Let’s delve into a practical observation regarding key fob batteries and performance.
One user encountered an aftermarket key fob for their vehicle that was designed for a single CR2032 battery. This design choice immediately raises a question because the space intended for batteries appeared limited, seemingly unsuitable for even two CR2016 batteries, which are thinner. Intriguingly, the seller had already installed a CR2032 battery, slightly thicker and with a marginally higher amp strength than a CR2016.
To understand the implications, it’s crucial to look at the specifications. A comparison reveals that a CR2032 battery boasts approximately double the capacity of a CR2016. Both are 3-volt lithium-ion batteries, but capacity directly relates to battery life – how long the battery will last before needing replacement. However, battery life isn’t the only factor at play.
Despite having the same diameter and voltage, CR2016 and CR2032 batteries are not interchangeable due to their differing thicknesses. Furthermore, examining battery capacity in milliampere-hours (mAh) clarifies the distinction:
- CR2016: 75 – 90 mAh
- CR2025: 150 – 165 mAh
- CR2032: 210 – 230 mAh
Logically, two CR2016 batteries would offer a combined capacity nearing or exceeding that of a single CR2032. This leads to the theory that using two CR2016 batteries might enhance signal strength compared to a single CR2032 in a key fob. Indeed, even with a single CR2032 in the aftermarket fob, a signal was being transmitted, suggesting functionality, but potentially at a reduced strength.
Ultimately, in the user’s experience, opting for a used OEM (Original Equipment Manufacturer) key fob proved to be a more reliable solution. This experience highlights the nuances of key fob battery selection and suggests that for optimal performance with your 2001 Pt Cruiser Key Fob Programming, battery type and configuration can indeed matter.
