What is the definition of a key fob?

Key fobs are remote control that lets you open and start your vehicle without having to insert a metal key in the ignition. It is a small, lightweight device that has a microchip which holds information such as an unique ID as well as an antenna that can send and receive signals. The microchip transmits radio frequencies with the receiver in your vehicle. These signals are a type of near-field communications (NFC) which allows for contactless payment, as well as other features requiring proximity.

Depending on your key fob's type, it will have different capabilities. Certain systems, for instance keep track of who entered the building and when. This is useful in preventing crime. Security measures can also be included by using encrypted keys, which make it harder to copy. Prox cards are an extremely popular fob design and are commonly called 125khz cards, 26-bit prox, or proximity fobs.

The majority of key fobs utilize small, coin-shaped batteries known as button cells. These batteries are found in many places like general stores, home improvement centres, and auto parts stores. It is crucial to select the right size battery for your key fob because different sizes of batteries have different discharge characteristics that can affect the way your key fob functions.

It is usually possible to tell if the battery in your key fob is dead by pressing the buttons, and then watching the LED light. If the light on the LED doesn't blink, it indicates that the battery is dead and has to be replaced. You can also use a voltmeter on the battery to test its voltage. A fully charged key fob should show around 3 Volts. If the battery shows less than 3 Volts, it is considered to be low and needs to be replaced.

To replace the battery, you must first remove your key fob. Find the notch that divides the two halves. You can use a screwdriver a knife, or even your fingers to push into this notch and then wedge the two halves apart. When the halves are separated take a look for a screw holding in the back of the key fob and loosen it. Save the screw in an accessible area such as a resealable cup or bag to avoid losing it.
