The key fob originated in the late 1980s as a security device for vehicles, providing a convenient way to unlock doors and start engines without traditional keys. Initially developed for remote entry systems, key fobs evolved from basic transmitters to more advanced devices featuring keyless entry, alarm systems, and even smart technology integration. Their design and functionality have expanded over time, leading to widespread adoption in various applications beyond automobiles, including access control for buildings and electronic devices.

How Reset key fob?

The key fob doesn't get reset... the keyless entry module gets programmed to accept commands from that key fob. If your key fob suddenly stops working and it's not a battery issue, then you either have a problem with your key fob itself, or the keyless entry module, and it'll need to be diagnosed and repaired accordingly.
