Car key fobs are a convenient way to lock, unlock, and start your car without having to insert a physical key into the door or ignition. However, one of the most common concerns about key fobs is their range – how far away from the car can you be and still use the key fob? In this article, we'll discuss the range of a car key fob and what factors can affect it.

The range of a car key fob varies depending on the type of fob and the manufacturer. Generally, most car key fobs have a range of 50 to 100 feet. However, some key fobs can reach up to 500 feet in ideal conditions.

Several factors can affect the range of a car key fob. The first and most significant factor is interference. The range of a key fob can be reduced by walls, buildings, trees, and other obstacles that block the signal. This means that the range will be shorter in urban areas than in open fields or rural areas.

Another factor that can affect the range of a car key fob is the battery. If the battery is low, the range of the key fob will be reduced. Therefore, it's essential to replace the battery when the key fob stops working at a distance that it previously worked.

The age and condition of the key fob can also affect its range. As the key fob gets older, it may lose its ability to transmit the signal as far as it used to. Additionally, damage to the key fob can affect its range.

Finally, weather conditions can affect the range of a car key fob. Heavy rain, snow, and other extreme weather conditions can reduce the range of the key fob. This is because water and other elements can interfere with the signal.

In conclusion, the range of a car key fob varies depending on the type of fob, manufacturer, interference, battery, age and condition, and weather conditions. If you're having trouble using your car key fob, you may want to try getting closer to your car or replacing the battery.
