However, in addition to the battery, there could be other reasons your key fob may not be working. Damage to the physical, exposure to water or internal component failure could be the reason. If your key fob has stopped working, replace the battery. Be sure to have the right size battery.

In order to access the key blade, you'll need to locate the notch located in the middle of the fob. The notch is typically a circular shape that is concealed by the fob's plastic casing. If you're looking to be extra cautious, you can use a multimeter to check the voltage of the battery. The majority of modern key fobs come with an integrated voltmeter, however you can buy a multimeter at most hardware shops for a few dollars.

Fortunately, most of the times, it's simple to diagnose and repair a problem with remote key fobs, and changing the battery is typically all that's needed. Modern car key fobs come with several buttons that can perform various functions. For instance, they can be used to lock and unlock the doors and activate the panic button, and even open the trunk. When the button is pressed the fob transmits a radio signal with a code that is recognized by a receiver in the car. Some fobs include buttons to start the car, which is useful on cold winter mornings as well as hot summer days. Typically, the buttons on keys can be reset by taking the device apart and then checking to ensure they're not damaged or stuck. Key fobs aren't typically designed to be taken apart, but the battery connectors on a key fob could get loose as time passes. If key repairs on the button have been disconnected from the circuit board and need to be soldered, a simple job is enough to get them back on track and restore the fob to full function. If a fob is damaged or dropped, the buttons may be broken, misaligned, or out of alignment. These problems are more difficult to fix on your own.
