What’s a Key Fob: Portable Convenience for Your Home Security System

Posted: November 07, 2019

Most home security systems come equipped with a remote key fob system as an alternative method of entry. Key fobs are small devices that use radio transmissions to allow access to a restricted area. Commonly used in cars, you now use them to secure things around the home. From garage door openers to the security system devices that help protect our families.

What does FOB stand for?

The initial usage of a key fob was a fashionable or functional attachment to your keys, dating as early as 1888.

Today, the fob acronym is believed to stand for “frequency operated button.” This technology first appeared in the 1980s within the automobile industry. It was introduced in cars like the Ford Thunderbird, Mercury Cougar, Lincoln Continental and Lincoln Town Car. Initially, the technology was used specifically to lock or unlock vehicles in the place of traditional keys and evolved into controlling moon roofs and rear hatches.

How does the key fob work with your home security system?

The system comes equipped with a panic button, which will sound a high-decibel alarm when pressed. These signals distress from anywhere within the receiver distance. This function is useful if you notice a crime about to take place on our property, but you are not within reach of your security panel.

Earlier key fob systems of the 1980s used infrared light and required a clear line of sight to function. Modern key fob systems transmit coded signals via radio waves and are considered to be more secure. A signal is sent from the key fob system and retrieved by the receiver. Most key fob systems have to be within a reasonable distance to function properly. The key fob should ideally be within 15-60 feet of the receiver to ensure signal transmission.
