This article outlines everything you need to know about FOB key replacement, including the types of fobs, costs, and the replacement process.
Understanding FOB Keys
A key fob is a small electronic device that communicates with your vehicle’s locking mechanism via radio frequency. It typically allows for features such as remote locking and unlocking of doors, starting the engine, and even opening the trunk. Modern FOBs may also include additional features such as panic alarms, keyless entry, and vehicle tracking.
Types of Key FOBs
There are generally two main types of key fobs:
Standard Key Fobs: These fobs offer basic functions such as locking and unlocking doors. They often require a traditional key to start the ignition.
Smart Key Fobs: Smart fobs allow for keyless entry and ignition. They can remain in the owner’s pocket or bag while unlocking the doors and starting the engine automatically.
