There are instances when a Mazda 3 owner might need to change the battery on their key fob. This is a straightforward task that you can complete yourself.

To change the battery, look for the small button located on the back of the key fob. Press it and then take off the cover.

Lost Keys

The loss of your car keys used to be a minor inconvenience. You could replace keys at any hardware store, locksmith, or dealer, and it was fairly inexpensive to do it. Your car's high tech key fob can do much more than just secure the vehicle and open it. However, that added convenience comes with costs - more expensive replacements.

The key fob features an embedded security chip within it that sends a specific code to the car's computer in order to let you unlock and start the engine. The key fob is also capable of controlling some other functions, like opening and closing the windows when you're in a hot spot and calling your car to you for easier reverse maneuvers into an awkward spot (a feature available on some Genesis GV60 and Hyundai Sonata sedans).

Fortunately, Mazda's remotes aren't as expensive from other automakers. With a little bit of knowledge, you can replace the battery in your key fob on your own. You'll require a flathead screwdriver as well as the new CR2025 to do this. Be sure to use the directional buttons and red button to unlock and lock the doors before changing the battery.

If you're looking to cut costs, find a Mazda 3 keyfob online that is OEM. It doesn't need programming by a locksmith or dealer. eBay offers a wide selection of options, but they may not be the same color as your existing key fob.

Lockouts

A driver being locked out of their vehicle is among the worst situations that can occur. There are some tricks drivers can use to gain access into their vehicle. They should first try calling their local Mazda dealership or locksmith. This is a viable option, as it will likely be less expensive and faster than calling a tow-truck. The locksmith or dealer will require a key code from the database to create a new key fob, which usually costs about $100. This is why it's important to keep this code in a safe place.

If you are stuck in the car, the second thing you can do is search for an auxiliary key that is located on the underside. There is typically small, round button that can be press and held. This will open the doors of the vehicle and allow the driver to open them manually.

Another way to enter a locked vehicle is by using the emergency override feature. This will allow the key fob's device to bypass the functions that are suspended by the theft-deterrent system. This will usually activate the danger warning lights and emit a to confirm that the doors, lids for fuel-filler, or liftgate are closed.

Transponder Chips

You'll need to replace it if the key fob has an embedded transponder in the metal head of the L-shaped key. These chips contain an identification code that allows you to start your car.

The antenna ring emits radio frequency energy when you insert your key in the metal and switch it on. The energy reaches the chip's transponder located in the key. The chip responds by sending a code to the antenna ring. This tells the car that the key is legitimate.

Most Mazdas are equipped with a transponder chip with a rolling code which changes its code each time you turn the key. This means that the key you're using won't be compatible with your vehicle until you have a duplicate with the exact code inside the ignition cylinder.

It's not difficult to make your own replacement key. If you're able to find an original key, insert it inside your Mazda and turn the ignition to ON. You can copy the information from the key to another key, if it starts your mazda replacement key. You can also use the eraser process on your key fob in order to erase the current code, if necessary. This method isn't 100% guaranteed to work because some transponder chips that are recycled might not work properly.

Programming

The loss of your car keys can be an expensive and lengthy process. Mazda has made programming and adding an additional car key simple. You can do it in just a few steps and you don't need to pay the dealer for the service. You can avoid paying for a tow or dealership fees if you have an additional car key.

You'll first need to purchase an extra battery for your key fob. It can be found at a big box retailer or at a hardware store for approximately $10. You'll also need a flathead screwdriver in order to open the fob. The screwdriver's head must fit in a small slot or space on the side of the fob. After you've removed the case you'll have to replace the battery that was in the case with the new one.

It's time to add the new key fob into your vehicle. To do this, simply insert the working key into the ignition, and turn it on. After about five seconds, and then turn off the ignition. Repeat the procedure with a second working key, then your new (or spare) key. Once you've completed the procedure and your Mazda should now be able to be started using the newly programmed keys. If it doesn't, there may be another problem with your key fob or vehicle.
