This communication allows for various functionalities, most commonly keyless entry into vehicles, remote starting, and alarm systems. You might also recognize similar devices as garage door openers or keyless entry systems for hotel rooms – all operating under the same fundamental principles as a car key fob for sale. Specifically, when we talk about key fob for sale in the automotive context, we are referring to the remotes designed for factory or dealer-installed keyless entry systems in cars and trucks.
A Brief History of the Term “Key Fob”
Interestingly, the term “key fob” predates modern vehicle technology by centuries. Its origins can be traced back to watch fobs, decorative ornaments attached to pocket watch chains, popular since the 1800s. By the 1950s, the term evolved to describe promotional items attached to car keychains. When remote keyless entry systems emerged for vehicles, it was natural to call their remote controls “key fobs.” This historical context explains why the term “key fob” is now widely used for almost anything attached to a personal keychain, but particularly relevant when you’re searching for a key fob for sale for your car.
