Lost Keys

Before the 1990s the 1990s, losing your car keys was an annoyance that was not a major inconvenience. It was comparatively inexpensive to replace them in any hardware store, dealer, or locksmith. Today, your vehicle's high-tech key fob is capable of doing more than just unlock and start your car and that convenience comes at a cost and that's more expensive replacements.

The key fob comes with an embedded security chip in it that sends a specific code to the car's system to let you unlock and start the engine. The key fob is also capable of controlling various other functions, such as opening and closing the windows when you're in a hot spot and summoning your car for easier reverse maneuvers into an area that is tight (a feature available on some Genesis GV60 and Hyundai Sonata sedans).

Fortunately, Mazda's remote fobs aren't as expensive from other automakers. You can even replace the key fob battery yourself with a bit of knowledge. To do this, you'll need a small screwdriver with a flat head, an updated CR2025 battery, and your key fob. Make sure to use the directional buttons as well as the red button to lock and unlock the doors prior to changing the battery.

If you want to save money on a Mazda 3 key fob replacement you can find one online that is OEM and does not require programming by a dealer or locksmith. eBay has many options, however, they might not be the same color as your existing key fob.

Lockouts

One of the worst things that can happen to a driver can be getting locked out of their vehicle. There are some tricks drivers can employ to gain entry into their vehicle. First, they can try calling their local locksmith or Mazda dealership. This is a great option as it's likely be less expensive and quicker than calling a tow-truck. The locksmith or dealer will require a key code from the database in order to cut you a new key fob, which will usually cost around $100. It's important to keep the code secure.

If you are stuck in the car, the second thing you can do is search for an auxiliary key located under the car's underside. The button is usually smaller and round, but can be hit. This will open the doors to the vehicle and allow the driver to open them by hand.

Another way to gain entry into a locked vehicle is by using the emergency override feature. This will allow the key fob to take over functions that are not controlled by the theft-deterrent system. This will trigger the alarm lights and sound to confirm that the doors, the lid for the fuel filler, or liftgate is closed.

Transponder Chips

You'll need to replace it if the key fob is equipped with a transponder embedded in the head of the metal L-shaped key. These chips come with an unique identification code that is used to start your vehicle.

The antenna ring emits radio frequency energy when you insert your key made of metal and switch it on. G28CarKeys reaches the chip transponder inside the key. The chip responds with an encoded code that is sent to the antenna ring, telling the car that it's a valid key.

Most Mazdas come with transponder chips with a changing code that changes every time you turn it. This means that the key you're using will never work on your vehicle until you've got a copy that has the exact same code in the ignition cylinder.

It's possible to create your own replacement keys. If you're able to locate an original key, insert it into your Mazda and turn the ignition to ON. If the key is able to start your vehicle, you'll be able to copy the information to the other working key. You can also try using the eraser procedure on your key fob to remove the current code, in the event that it is needed. This method is not 100% guaranteed to work, as some transponder chips can fail to function properly.

Programming

The loss of your car keys can be costly and time-consuming. Mazda has made adding and programming a third car key a breeze. This can be accomplished in a couple of steps, and you don't need to pay a dealer for this service. You can avoid paying for towing or dealership fees if there is an additional car key.

The first step is to find a replacement battery to the fob. You can purchase one from a hardware store or large box retailer for around $10. To open the fob, you'll require a flathead screwscrew. The screwdriver's head should fit into small slots on the side of your fob. After removing the case replace the battery that was in it.

Now you can program your new key fob. Insert the first key that operates into the ignition and turn it ON. For about five seconds, you should wait before turning the ignition off. Repeat the process with a different working key, and then with your new (or spare) key. After this is done your newly programmed key should be capable of starting your Mazda. If it's not, it could be a problem with the key fob.
