The Chrysler Town & Country key fob is a marvel of convenience, offering remote locking, unlocking, and other functionalities right at your fingertips. Many owners might be surprised to learn that their key fob likely has a hidden capability: a sixth button for a panic alarm. While not always functional out of the box, especially in European models, the internal components often possess the micro-switch for this feature. This article delves into the intricacies of Chrysler Town & Country key fob programming, focusing on how you might unlock the potential of this hidden panic button and understand the components within your remote.
Many Chrysler Town & Country owners are familiar with the standard five-button key fob. However, a closer look inside reveals a printed circuit board (PCB) designed for six buttons. This is because the same PCB is often used across different markets and models, some of which do utilize a six-button configuration, including a dedicated panic button.
The key to understanding this lies within the construction of the key fob itself. It’s composed of several layers: the outer casing, the PCB with micro-switches, and a conductive membrane sheet that sits between them. This membrane is crucial; when you press a button on the fob, it presses down on the membrane, which in turn completes a circuit on the PCB, triggering the desired function.

The issue often encountered, particularly with European Chrysler Town & Country models, is that while the PCB has the micro-switch for the sixth button (panic), the conductive membrane sheet may only be traced for five buttons. This means there’s no conductive pathway on the membrane to activate the panic button micro-switch, even though the hardware is physically present.
Unlocking the Panic Button Potential
For those looking to enable the panic button, the solution lies in obtaining a conductive membrane designed for a six-button configuration. One potential source for this component is from six-button key fobs commonly found in the American market. These fobs are readily available online through platforms like eBay and specialized key fob retailers.
You could consider purchasing a complete six-button key fob from a US supplier. The strategy here would be to carefully disassemble both your existing five-button fob and the acquired six-button fob. You would then transplant the six-button conductive membrane from the US fob into your original fob, ensuring compatibility with your existing PCB and casing.
Key Fob Programming and Transponder Chips
It’s important to note that simply having a six-button fob or enabling the sixth button mechanically is only part of the process. The key fob also needs to be programmed to your specific vehicle to function correctly. Furthermore, the transponder chip within the fob, typically an ID46 type, is crucial for starting the car. When sourcing replacement fobs or components, ensure compatibility with your Chrysler Town & Country model year, particularly regarding the transponder chip. Be cautious of generic or Peugeot-specific ID46 chips, as they may not be compatible with Chrysler systems.
For programming instructions, valuable resources are available online, such as FreeRemoteInstructions.com, which offers guides for various Chrysler models. These guides typically involve a sequence of actions using the vehicle’s ignition and doors to enter programming mode and synchronize the new key fob.
Finding the Right Parts
If you’re venturing into modifying your key fob to enable the panic button, resources like eBay (search for “Chrysler 6 button key fob”) and specialized retailers like keyless-remotes.com can be invaluable. These platforms offer a range of key fobs, cases, and components that may be necessary for your project. When searching, be specific with your vehicle year and model to ensure part compatibility.
In Conclusion
While your European Chrysler Town & Country key fob may appear to be a standard five-button remote, it likely holds the hidden potential for a sixth panic button. By understanding the internal components, particularly the conductive membrane, and sourcing compatible parts, you might be able to unlock this feature. Remember to consult programming guides and ensure transponder chip compatibility for a fully functional key fob. Exploring these options can enhance the functionality of your existing key fob and potentially add an extra layer of security to your Chrysler Town & Country.
