What is a keyfob?

Key fobs are remote control that lets you open and start your vehicle without having to insert a key made of metal in the ignition. It's a small gadget that has a microchip on which information like a unique ID is stored as well as an antenna for sending and receiving signals. The microchip communicates with the receiver inside your car using radio frequencies. These signals are a kind of near-field communications (NFC) that allows for contactless payments and other features that require proximity.

Depending on the key fob's type the key fob will have various capabilities. Certain systems, like, keep a record of who came into the building and when. This is useful in preventing theft. There are also security measures that could be added, like encrypted keys that make it impossible to copy them. Prox cards are an extremely popular fob type, and are often called 125khz cards, 26-bit prox or proximity fobs.

Most times, you can determine the battery of your fob is dead by pressing any buttons on it and observing the light source that is lit by the LED.

Make sure you save the screw in a secure area, such as a resealable bag or cup to prevent it from being lost.
