How Key Fob Works

Key fobs have become standard for drivers across the world. They bring many benefits since they are convenient and help protect against theft. However, when a key fob stops functioning, it can be extremely frustrating for the vehicle’s owner. While losing your car keys can be annoying, it can be even more aggravating when the keys are right there in your hand, but your car still refuses to start. When you’re faced with such a problem, it helps to understand how key fobs are designed to work in the first place. Being informed ahead of time can help drivers remain level-headed when dealing with problems. At Top St. Louis Locksmith, we provide residential, commercial, and automotive services for local clients, including key fob programming and car key making. Here are some helpful details that can assist you the next time you run into trouble with your key fob. 

How Do Key Fobs Work?

A key fob utilizes electromagnetic radio waves to help prevent theft. An RFID or radio frequency identification chip is located inside the transponder key. Every key has a unique code, like an electronic fingerprint. The RFID chip works similarly to a barcode, and the correct key must be used for the car’s engine to start. If you are near your vehicle, then the code should be easily read by the system. Unfortunately, it doesn’t always work out the way it’s supposed to. 

Common Key Fob Issues

There are a variety of reasons why a key fob can stop functioning properly. In the majority of cases, the cause is a dead battery. Thankfully, the only task required to fix this problem is to replace the battery. However, if you have replaced the battery and it still won’t work, a more complicated issue could be to blame. Your vehicle might have an electrical problem, or your key fob may be damaged or need to be reprogrammed. 

How Can a Mobile Locksmith Help?

It can be easy to panic when you realize your car won’t start. After all, dealing with issues like this could make you late for an important appointment or event. In the past, it might have been necessary to call a local tow truck, dealership, or auto mechanic to get the help you needed. Thankfully, that is no longer the case. Modern locksmiths have access to advanced technologies that allow us to perform various automotive-related key and lock tasks.
