Understanding How Key Fobs Work
Before we dive into the solutions, it’s essential to understand how key fobs work. A key fob is a small device that contains a small battery, a microchip, and a transmitter. When you press the unlock or lock button on your fob, it sends a signal to the car’s computer, which then performs the desired action.
The battery in your fob is usually a small, round battery that can last anywhere from 2 to 5 years, depending on usage and quality. However, if you use your fob frequently, the battery can drain faster, leaving you with a dead fob.
Types of Key Fobs
There are two main types of key fobs: passive and active. Passive key fobs are the most common type and use a battery to send a signal to the car’s computer. Active key fobs, on the other hand, use a more advanced technology that doesn’t require a battery.
Passive key fobs are more prone to battery drain, especially if you carry other electronic devices in your pocket or purse. This is because the fob can pick up signals from other devices, causing it to drain faster.
