Navigating the world of aftermarket key fobs for your 2006 PT Cruiser can sometimes lead to unexpected discoveries, especially when it comes to battery compatibility. Many owners find themselves questioning the best battery type to ensure optimal performance and signal strength for their key fobs. This exploration delves into the nuances of CR2016 and CR2032 batteries in relation to your 2006 Pt Cruiser Key Fob, shedding light on why battery selection matters.
CR2016 vs. CR2032 Batteries: What’s the Difference?
When examining key fob batteries, the CR2016 and CR2032 are frequently mentioned, both being 3V lithium coin cell batteries. The primary difference lies in their physical dimensions and capacity. A CR2032 battery is slightly thicker than a CR2016, effectively holding about twice the capacity. While both deliver the same 3 volts, the capacity dictates battery life, meaning a CR2032 should theoretically last longer.
However, the thickness difference is crucial. Key fob battery compartments are designed for specific battery sizes. While an aftermarket fob might be modified to accommodate a single CR2032, the original design and many aftermarket alternatives often specify CR2016 batteries, sometimes in a dual configuration.
Signal Strength: Two CR2016 Batteries vs. One CR2032?
A common question arises: does using two CR2016 batteries offer superior signal strength compared to a single CR2032 in a 2006 PT Cruiser key fob? While a CR2032 boasts a higher capacity (around 210-230 mAh) compared to a CR2016 (approximately 75-90 mAh), using two CR2016 batteries effectively doubles the capacity available from the CR2016 type.
The theory that two CR2016 batteries might provide a stronger signal isn’t directly tied to voltage, which remains at 3V for both configurations. Instead, it touches upon the available current and potentially the way the key fob circuitry draws power. Anecdotal evidence and some battery specialists suggest that in certain applications, the configuration of two batteries might indeed influence signal output.
Aftermarket vs. OEM Key Fobs: Battery Considerations
The original equipment manufacturer (OEM) key fobs for your 2006 PT Cruiser are engineered for specific components, including battery type and configuration. Aftermarket key fobs, while often more affordable, may sometimes deviate from these specifications. Some aftermarket fobs might be designed to house a single CR2032 battery, potentially due to internal design or ease of manufacturing.
However, for optimal and reliable performance, particularly signal strength and longevity, adhering to the originally intended battery specification is generally advisable. If your 2006 PT Cruiser key fob was originally designed for CR2016 batteries, especially a dual CR2016 setup, sticking with this configuration or seeking an OEM replacement can mitigate potential issues related to battery compatibility and signal reliability.
Conclusion: Choosing the Right Battery for Your 2006 PT Cruiser Key Fob
Ultimately, when replacing the battery in your 2006 PT Cruiser key fob, understanding the nuances between CR2016 and CR2032 batteries is key. While a CR2032 offers longer battery life due to higher capacity, the physical dimensions and intended design of your key fob should guide your choice. For guaranteed compatibility and signal reliability, particularly if your original fob used CR2016 batteries, opting for the correct type or considering an OEM replacement fob is a prudent approach to ensure seamless operation of your vehicle’s keyless entry system.
