A key fob, also called a fob key, is a compact electronic device that empowers drivers to execute multiple functions for their vehicles effortlessly. These functions include locking, unlocking, and starting the car with a simple button press. The device uses radio waves to establish seamless communication with the car’s onboard computer.
Ensuring the security of your fob key is crucial, as it grants access to your car and even enables engine ignition. Many key fobs have advanced security features, like a required code entry before starting the vehicle.
By prioritizing the protection of your key fob, you can safeguard your car and enhance its overall security.
What Does Fob Stand For?

The term “fob” has a rich history and has undergone various interpretations. Initially, it denoted a small pocket utilized for safeguarding valuable items. In the early 1900s, it also encompassed the decorative pendant attached to a pocket watch chain. Later, during the mid-1900s, “fob” evolved into a common designation for any ornament suspended from a keychain.
With the popularity of remote keyless entry systems in the 1980s, car dealers and mechanics adopted the term “fob” to describe the remote transmitter for unlocking and locking car doors. Presently, these devices are commonly referred to as fobs or key fobs.
How Does a Key Fob Work?
When a driver presses a button on the key fob, it sends a signal to the car. The car performs various functions, such as unlocking the doors or starting the engine. Some key fobs utilize rolling code technology, which changes the code with each use.
This provides an additional level of security by deterring unauthorized access. The code changes with each use, making the car unlocking process non-reproducible.
Fob Key Meaning and Security Concerns
Certain key fobs employ rolling code technology, which alters the code with each use. This provides enhanced protection against unauthorized access, as the code becomes obsolete after a single use. Although key fobs offer convenience, they also present specific security vulnerabilities.
Criminals have devised a technique known as a “relay attack” to intercept the communication between a car’s key fob and its computer. This cunning method enables them to unlock the vehicle effortlessly and even start the engine.
Certain car manufacturers have introduced advanced security measures, including motion sensors and biometric authentication, to counteract such threats. These safeguards are specifically designed to thwart these types of attacks and ensure the safety of your vehicle. Key fob programming is important for your vehicle’s security.
Car Fobs and Key Fob Batteries
Key fobs rely on batteries that require periodic replacement. While some key fobs have a removable cover for easy battery access, others may necessitate a particular tool or a visit to the dealership. Monitoring the battery level to ensure the key fob functions flawlessly is crucial. Knowing how to open a key fob is a good thing.
