Introduction to Key Fobs
Before we dive into the specifics of the half circle with an arrow, it’s essential to understand the basics of key fobs and their evolution. Key fobs, short for keyless entry fobs, are small, portable devices that allow car owners to lock, unlock, and start their vehicles without the need for a traditional key. These devices use radio frequency identification (RFID) or radio frequencies to communicate with the car’s computer system, enabling a range of convenient features.
The first keyless entry systems were introduced in the 1980s, but it wasn’t until the 1990s that key fobs became a standard feature in many vehicles. Today, key fobs are an integral part of the driving experience, offering a level of convenience and security that was previously unimaginable. With the advancement of technology, key fobs have become more sophisticated, incorporating a variety of buttons and symbols that control different functions.
Understanding Key Fob Symbols
Key fobs typically feature a range of symbols, each corresponding to a specific function. These symbols can vary depending on the vehicle manufacturer and model, but some common ones include:
- A lock symbol, which locks the vehicle
- An unlock symbol, which unlocks the vehicle
- A circular arrow symbol, which is often associated with the vehicle’s alarm system
- A trunk release symbol, which opens the trunk
The half circle with an arrow is another common symbol found on key fobs. This symbol is often misunderstood, with many car owners unsure of its purpose.

When the half circle with an arrow is pressed on the key fob, it sends a signal to the vehicle’s computer system, which then starts the engine. The vehicle will run for a predetermined amount of time, usually between 10 to 15 minutes, before shutting off automatically. The remote start feature can be programmed to perform a range of functions, including turning on the air conditioning or heating, and activating the vehicle’s defroster.
It’s worth noting that not all vehicles are equipped with remote start, and the half circle with an arrow may have a different function on certain models.
