What is a key fob and how does it work to start a car?

Key Fob Definition

A key fob, also known as a remote keyless system, is an electronic device that controls access to a vehicle. It typically contains buttons for locking and unlocking doors, opening the trunk, and sometimes even starting the engine.

How Key Fobs Work

Key fobs communicate with the car’s onboard computer using radio waves. When you press a button on the key fob, it sends a signal to the car’s computer, instructing it to perform a specific action. The car’s computer verifies the signal and, if it matches what it’s expecting from that particular key fob, performs the requested task.

The technology used in modern key fobs offers increased security as they are uniquely programmed to work only with your vehicle. The system can be programmed to recognize only certain signals or codes sent by your specific key fob.

Benefits of Key Fobs

– Convenience: You no longer need to search through your pockets or purse for keys when entering or exiting your vehicle.
– Increased Security: With unique programming for each individual fob, it provides an extra layer of protection against theft.
– Remote Start Capability: Some vehicles have the ability for you to start your engine remotely using the key fob, making cold mornings much more comfortable.

How do you know if your key fob battery is dead?

If you notice that your key fob isn’t working correctly or not at all, there could be an issue with its battery life. However, there are some signs that will help you determine whether or not this should be considered as a possibility:

Symptoms of Dead Key Fob Battery

– Reduced Range: If you’re having to get closer to the car than usual for the key fob to work, it is a good indication that the battery may be dying.
– Slow Response: If there is a delay between pressing a button and the action being performed by the car, this could also be a sign of reduced battery life.
– Continuous Warning Sounds: Most vehicles have warning sounds or flashes when the battery is low. If you hear any continuous warning sound after pressing any button on your key fob, it’s an indicator that your key fob battery needs a replacement.
