Understanding Automotive Key Fobs: Functionality and Replacement Options
Automotive key fobs, also known as remote keyless entry systems, serve multiple purposes in vehicle operation. They allow users to lock and unlock doors, open the trunk, activate panic alarms, and even start the engine in some cases. But how do they accomplish all this?
How Do Automotive Key Fobs Work?
Key fobs operate through radio frequency (RF) communication. When you press a button on your key fob, it sends a unique signal to your vehicle's receiver. This signal is often encrypted to prevent unauthorized access. Here’s a closer look at their primary functions:

Modern vehicles utilize sophisticated encryption methods to secure signals between key fobs and car receivers. This reduces risks associated with theft or duplication.
