What is an important key fob?
A key fob can be used as a remote control to unlock and start your car without having to insert a metallic ignition key. It is a small, light device with a microchip. It stores information like a unique ID and an antenna to send and receive signals. The microchip communicates via radio frequencies with the receiver inside your vehicle. These signals are part of near-field communication (NFC), allowing payment via contactless, as well as other features that require proximity.
Based on the type of key fob you've got it can provide different features. Some systems, for example keep track of who came into the building and when. This can be extremely useful in preventing crime. Security measures can also be included by using encrypted keys, which make it more difficult to copy. Prox cards are a well-known fob and are also called 125khz prox, 26-bit prox, or proximity fobs.
It's recommended to have a spare key fob for your vehicle in the event that one is lost or stolen. It's convenient and cost-effective to program a third keyfob yourself. It is important to note that the process varies between manufacturers and can be a bit complicated. It may take some research to find the proper instructions and steps, but it's well worth it to have a better key fob that helps you reach your destination in safety.

Fortunately, replacing the battery in your key fob is easy and can be done at home with some tools. https://www.thekeylab.co.uk/mazda-car-keys/ has put together this guide to help you open the keyfob and replace batteries.
To begin, press the button for the auxiliary key on the back of the key fob to detach the metal auxiliary key. Once the key is removed, you will see an opening on either side of the case. Gently pry the case open by using a tape-wrapped screwdriver. It should come apart easily without harming the rubber ring which the battery sits.
Once the battery has been removed, take it off and put it away somewhere that you won't forget about it. Place the new battery into its original position, making sure that the positive (+ side) of the battery is facing up. After the battery is in place, close up the case, making sure that both sides snap into the correct position. You're now ready to use your Mazda key fob once more!
What is the battery used for a key fob?
Most key fobs have small, coin-shaped batteries that are known as button cells. They are readily available at general stores, home improvement stores, and certain auto parts stores. It is essential to select the appropriate size battery for your keyfob. Different battery sizes have different discharge characteristics which could affect the way your keyfob functions.
You can usually tell if the battery in the key fob is depleted by pressing the buttons and then observing the LED light. If the LED light does not come on then the battery is dead. It is time to get it replaced. You can also test the battery with a voltage meter to determine what voltage it is running at. A fully charged key fob should show about 3 Volts. If the battery's reading is less than 3 Volts, it needs to be replaced.
To replace the battery, you must first open your key fob. Find the notch that divides the two halves. You can use your fingers or a screwdriver, or a knife to wedge the two halves. After the two halves have been separated, look for an unfastened screw on the back of the key fob, and take it off. Make sure you save the screw in a secure place, like a resealable cup or bag to ensure that you don't lose it.
How do you replace the battery on a key fob?
Key fobs are attached to the key ring, and it has buttons that can be used to lock or unlock your car and even remotely start it (one of their many nefarious uses). The fob transmits an electronic signal to the car, which allows it to do this, however that signal is powered by battery power. If the battery fails then your Mazda won't be able to do anything at all, and that can be a major disappointment. It's easy to replace the battery on the key fob.
The first step to open the key fob is to push the screwdriver's tip into the seam where the halves snap. There is often an opening in this seam, which makes pulling the two halves apart simpler.
After opening the case, gently pull on the key blade to remove the old battery. The new CR2025 should be inserted into the case, making sure that the plus side is on the right. Once the new battery is in place, place the black cover piece back on and slide the key blade in place.
