The History of Keyfobs
The first keyfob was invented in 1983 by German company Siemens. It was designed to be used as a remote control for televisions and other electronic devices. However, it wasn’t until the 1990s that keyfobs became popular in the automotive industry. The first car to use a keyfob was the 1993 Renault Safrane. Since then, keyfobs have become a standard feature in most cars.
How Keyfobs Work
Keyfobs use radio frequency identification (RFID) technology to communicate with the car’s computer system. When you press a button on the keyfob, it sends a signal to the car’s computer, which then performs the desired action. The range of the keyfob depends on the frequency used and the strength of the signal. Most keyfobs have a range of up to 50 feet.
Types of Keyfobs
There are two main types of keyfobs: traditional and smart. Traditional keyfobs have buttons that perform specific functions, such as locking and unlocking the car. Smart keyfobs, on the other hand, use proximity sensors to detect when the key is near the car. They allow you to unlock the car by simply touching the door handle and start the engine by pressing a button on the dashboard.
Benefits of Using Keyfobs
One of the main benefits of using keyfobs is convenience. You no longer have to fumble with keys to unlock your car or start the engine. Keyfobs also provide an added layer of security, as they use encrypted signals that are difficult to intercept. Additionally, some keyfobs come with features such as remote start, which allows you to warm up your car on a cold day before you get in.
Choosing the Right Keyfob
When choosing a keyfob, there are several factors to consider. The first is compatibility. Make sure the keyfob you choose is compatible with your car’s make and model. The second is range. If you frequently park your car far away from your home or office, you may want a keyfob with a longer range. Finally, consider the features you need. If you live in a cold climate, a keyfob with remote start may be a useful feature.
Conclusion
Keyfobs have revolutionized the way we interact with our cars. They provide convenience, security, and added features that make our lives easier. Whether you choose a traditional or smart keyfob, make sure to choose one that is compatible with your car and meets your needs. With the right keyfob, you can enjoy a hassle-free driving experience.
