This article will discuss how a car remote key system works and what makes it different from standard locks. By learning more about these systems, you’ll know how to choose the right locksmith services if your system breaks.

Read on to learn more about car remote keys and how they work.

What Is Car Remote Key?

Car remote keys have come a long way since they were first introduced in the 1980s. Nowadays, the remote car key also called a remote key fob, is a wireless remote used to unlock and lock a car door without needing a physical key.

It is a small, handheld device that transmits a radio signal to a receiver that is mounted on the car door.

How Does It Work?

Car remote keys work by using a combination of radio frequencies and transponder chips. The radio frequency is used to send a signal to the car’s central locking system, which then activates the transponder chip. This chip sends a unique code back to the car’s electronic control unit, unlocking the doors and starting the engine. 

The whole process happens in just a few seconds and is very convenient for drivers. The radio signal range varies depending on the remote but is typically around 30 feet.

What To Do if the Key Fob Stops Working?

The most common fix to get your car remote key working again is to replace the battery, as a remote start key fob uses small coin cell batteries that can die without warning. 

To change the car remote key battery, first, locate the transmitter. There will be a small cover on the back of the transmitter. Remove the cover and insert the new battery. Replace the cover and test the remote.

If that doesn’t work, you can also try cleaning the remote key fob or checking for interference from other devices. If all else fails, consult the owner’s manual for troubleshooting tips or visit this link to check the car key repair services available. 

Other Uses of Car Remote Keys

Some car remote keys are not only designed to unlock/lock the door, but they can also start the engine, open the trunk and turn on the lights. Others have a panic button that, when pressed, will sound the car alarm.

Whatever the use, the car remote key is convenient and secure to control your car without fumbling for keys. So what are you waiting for? Try using car remote keys now!
