Lost Keys
Losing your car keys was an issue of minor importance. You could replace them at any hardware store, locksmith shop, or dealer, and it was fairly inexpensive to do it. The car's high-tech key fob can do more than simply lock and unlock the car. However, this added convenience comes with costs - more expensive replacements.
The key fob has a security chip embedded in it that sends a specific code to the car's computer to allow you to unlock and start the engine. The key fob is also capable of controlling other features, including opening and closing the windows when you're in a hot spot and summoning your car to make it easier to reverse into the tight spots (a feature that is available on certain Genesis GV60 and Hyundai Sonata sedans).
Fortunately, Mazda's remote fobs aren't as costly as those from other automakers. You can even replace the key fob battery yourself, with a amount of knowledge. To do this, you'll need a small screwdriver with a flat head, an updated CR2025 battery and your key fob. Use the red and directions buttons to lock or unlock your doors before changing the batteries.
If you're looking to cut costs look for an Mazda 3 keyfob online that is OEM. It doesn't require programming by a locksmith or dealer. eBay offers a variety of options, however, they may not be the exact color of your existing key fob.
Lockouts
One of the most devastating things that can happen to a driver is becoming locked out of their car. There are some tricks drivers can use to get inside their vehicle. The first step is calling the local locksmith or Mazda dealership. This is a good option since it's likely to be less expensive than calling for a tow truck and will be quicker too. The locksmith or dealer will need to buy a key code from the database to cut you a new key fob, which typically costs around $100. This is why it's important to save the key code in a safe spot.
If you are stuck in the car, the other thing to do is search for an auxiliary button on the bottom. The button is usually small and round that can be pressed. This will unlock the doors of the vehicle and permit the owner to open them by hand.
Another way to enter the vehicle locked is by using the emergency override feature. This allows you to use your key fob to bypass any functions that have been suspended by the theft deterrent system. This will activate the hazard lights and sound to ensure 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 that is built into the head of the L-shaped key. The chips are unique in identification number that is used by your car's engine to start the engine.
When you insert your key and turn it to ON the antenna ring emits the radio frequency energy that is received by the transponder chip inside the key's metal. The chip responds by sending a code to the antenna ring. This tells the car that the key is legitimate.
The majority of Mazdas have a transponder chip with an evolving code that changes every time you turn it. This means that the key you're using won't work with your car until you have a second copy with the same exact code in the ignition cylinder.
It's not too difficult to create your own replacement key. If you find a key that works then insert it into your Mazda. Turn the ignition ON. You can copy the information from the key to the other key in case it starts your Mazda. If necessary, you can also utilize the eraser on the key fob to remove the code. It's important to note that this method is not guaranteed to work, as some transponder chips recycled from the past might not be able to respond properly.
Programming
The loss of your car keys can be an expensive and time-consuming ordeal. Luckily, Mazda has made it easy to program and add an additional key. It is possible to do this in only a few steps and you won't have to pay the dealer for the service. If you have a spare car key this is the most efficient way to avoid having to pay for towing or dealership costs.
First, you'll need buy a new battery for the fob. You can purchase one at a hardware store or big box retailers for around $10. You'll also need an open-ended screwdriver that is flat to open the fob. The screwdriver's tip should fit into tiny slots on the back of your fob. After removing the case replace the battery that was in it.
Now it's time to set up the new key fob in your vehicle. Insert the first key that works into the ignition and turn it on. It should be on for about five seconds then switch off the ignition. Repeat the process with a different working key, then your new (or spare) key. After you've completed this the Mazda should have the ability to be initiated using the newly-programmed keys. If it doesn't it could be due to a problem with the key fob or vehicle.
