For owners of the 2007 Chrysler Town and Country, the key fob is an essential part of vehicle access and security. While many are familiar with the standard functions of lock, unlock, and remote start, some may have noticed a sixth button position on aftermarket key fob cases, often intended for a ‘panic’ button. This raises questions about whether it’s possible to enable this extra button and fully understand your key fob’s capabilities. Let’s delve into the intricacies of programming your 2007 Chrysler Town and Country key fob and explore the potential of that intriguing sixth button.
Many owners, particularly in Europe, have discovered that their standard 5-button key fobs actually contain a circuit board equipped for six buttons. This discovery often leads to the purchase of aftermarket 6-button key fob cases, hoping to activate a panic button feature. These cases, readily available online, are designed to accommodate the existing internal components of your current fob, seemingly offering an easy upgrade.
However, the simple swap of cases often reveals a hidden limitation. Despite the presence of a sixth micro-switch on the circuit board, the panic button typically remains unresponsive. The reason lies within a small but crucial component: the conductive membrane sheet that sits between the circuit board and the key fob shell.

This membrane, essential for translating button presses into electronic signals, is often configured for only five buttons in European models. Even though the micro-switch for the sixth button is present on the PCB, the corresponding conductive track on the membrane is missing, effectively disconnecting the panic button.
So, while physically, you might be able to assemble a 6-button key fob using your existing circuit board and an aftermarket case, the functionality will remain limited to five buttons due to this missing conductive pathway.
For those determined to enable the panic button or simply have a fully functional 6-button fob, the solution often points towards sourcing a complete, pre-programmed 6-button key fob, particularly from the US market. These US versions are designed to fully utilize all six buttons, including the panic feature, and come equipped with the necessary conductive membrane.
To make a US-spec 6-button fob work with your 2007 Chrysler Town and Country, you would typically need to transfer your existing circuit board into the new 6-button fob case, ensuring it includes the correct 6-button conductive membrane. Furthermore, programming the transponder chip to your vehicle is crucial for the key fob to function correctly.
Programming instructions for Chrysler key fobs are widely available online, and usually involve a sequence of steps using your vehicle’s ignition and door locks. It’s important to follow these instructions carefully to successfully program your key fob.
In conclusion, while the allure of a 6-button key fob for your 2007 Chrysler Town and Country is understandable, especially with the readily available aftermarket cases, the missing conductive membrane in European models presents a hurdle for enabling the panic button with just a case swap. For full 6-button functionality, considering a complete US-spec fob and understanding the programming process is often the necessary step.
