Lost Keys

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

The key fob is equipped with security chips that transmit an exclusive code to the computer of the car to allow it to be unlocked and start it. The key fob is also capable of controlling some other features, including opening the windows when you're in a hot parking spot and calling your car to you for easier reverse maneuvers into the tight spots (a feature offered on some Genesis GV60 and Hyundai Sonata sedans).

Fortunately, Mazda's remotes aren't as expensive as those from other automakers. You can even replace the battery of your key fob yourself with a little knowledge. You'll require a flathead screwdriver as well as a brand new CR2025 to do this. Use the red and direction buttons to lock and unlock your doors prior to changing the batteries.

If you're looking to save money on the cost of a Mazda 3 key fob replacement search for one on the internet that is OEM and does not require programming by a dealer or locksmith. eBay has many options, but they may not be the exact color of your existing key fob.

Lockouts

A driver who is locked out of their vehicle is one of the most traumatic situations that can occur. There are several tricks drivers can use to gain access into their car. You should first contact their local Mazda dealership or locksmith. This is a great option for a variety of reasons, and it's likely to be less expensive and faster than calling a truck. A dealer or locksmith must buy a keycode from the database to make you a new fob. It will cost around $100. This is why it's important to save the code in a secure place.

If you are stuck outside your car, one of the things people can do is look for an additional key on the underside. There is usually small, round button that can be pressed and held. This will unlock the doors of the vehicle and allow the owner to open them by hand.

The emergency override feature is a second method of gaining access to an automobile that is locked. This allows you to use your key fob to disable any functions that were suspended by the theft deterrent system. This will activate the hazard lights and sound to verify that the doors, lids for the fuel filler, or liftgate is 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 come with a unique identification code that is used to start your car.

The antenna ring emits radio frequency energy when you insert your metal key and switch it on. The energy is then absorbed by the chip transponder within the key. The chip responds by sending a code to the antenna ring. This informs the car that the key is valid.

The majority of Mazdas have transponder chips with a code that is changing every time you turn it. This means that the key you're using isn't going to work with your car until you have a second copy with the same exact code inside the ignition cylinder.

It's not that difficult to make your own replacement keys. If you can locate an original key that works, insert it into your Mazda. Turn the ignition on. If the key starts your car, you can then copy the information to the working key. You can also try using the eraser process on the key fob to erase the current code, if needed. It's important to keep in mind that this method is not 100% guaranteed to work, since some transponder chips from recycled systems may not respond correctly.

Programming

Losing your car key can be costly and time-consuming. Mazda has made adding and programming a third car key a breeze. This can be done in a couple of steps, and you won't need to pay a dealer for this service. If you have a spare car key this is the best way to avoid paying for towing and dealer costs.

The first step is to buy a new battery for the fob. You can buy one at a big box store or hardware store for around $10. To open the fob, you'll need an screwdriver with a flat head. The screwdriver's head should fit into tiny slots on the back of the fob. Once you've removed the case, you'll need to replace the old battery with a new one.

Now it's time to program the new key fob for your vehicle. Insert the first key that works into the ignition and turn it ON. For about five seconds, and then turn off the ignition. Repeat the process with another key that works with your new (or additional) key. Once you've done this your newly programmed key should be capable of starting your Mazda. If it doesn't then there could be a problem with your key fob or vehicle.
