Before the 1990s lost car keys was an annoyance that was not a major inconvenience. It was comparatively inexpensive to replace them at any hardware store, dealer, or locksmith. Today, your automobile's high-tech key fob does much more than just lock and unlock your car, and that added convenience comes at a price that is more expensive replacements.
The key fob comes with an embedded security chip within it that sends a specific code to the car's computer in order to allow you to unlock and begin the engine. The key fob can also manage other features like the windows being rolled down in hot parking spaces and summoning the car to you so you can reverse in tight spaces (a feature that is available on certain Genesis GV60 sedans and Hyundai Sonata sedans).
Mazda's remote controls aren't the price of other car makers'. You can even change the battery in your key fob yourself, with a bit of knowledge. To do this, you'll need the smallest flathead screwdriver a brand new CR2025 battery, and your key fob. Use the red and direction buttons to lock and unlock your doors prior to changing the batteries.

Lockouts
A driver who is locked out of their vehicle is among the worst scenarios that could occur. Luckily, there are a few tricks that drivers can apply to gain access back into their vehicle. First, they can try calling their local locksmith or Mazda dealership. This is a great option because it will probably be cheaper than calling a tow truck, and it's faster too. The locksmith or dealer will need to buy a key code from the database in order to create the new key fob which is usually about $100. This is why it's vital to keep the code in a safe place.
If you're stuck in the car, the second thing people can do is look for an auxiliary button on the bottom. There is typically small, round button that can be pressed and held. This will unlock the doors to the vehicle and allow the driver to open them manually.
Another method to gain entry into a vehicle that is locked is using the emergency override feature. This allows the key fob to override the functions that are suspended by the theft-deterrent system. This will trigger the hazard lights and sound to prove that the doors, lids of the fuel filler or liftgate have been shut.
Transponder Chips
You'll need to replace it if your key fob has an embedded transponder in the head of the L-shaped key. These chips contain an unique identification code that is used to start your car.
When you insert your key and then turn it to the ON position the antenna ring emits the radio frequency energy that reaches the transponder chip in the key's metal. The chip responds by sending the code that's transmitted to the antenna ring, telling the car that it's an authentic key.
The majority of Mazdas have a transponder chip that is rolling code which changes its code each time you turn the key. This means that your key will not work on your vehicle until you have a duplicate with the exact code in the ignition.
It's not difficult to create your own replacement key. If you can find an appropriate key and fits into your Mazda. Then, turn the ignition on. If the key starts your car, you can then copy the data from it onto the other key that works. If you're in need, you can also use the eraser on your key fob to erase the code. It's important to keep in mind that this method is not guaranteed to work, as some transponder chips recycled from the past might not work correctly.
Programming
The loss of your car keys is an expensive and time-consuming process. Fortunately, Mazda has made it simple to add and program an additional key. You can do this in just a few steps and you do not have to pay the dealer for the service. You can avoid paying for towing charges or dealership fees if there is an additional car key.
It is necessary to purchase new batteries for the key fob. You can buy one at an hardware store or a big box retailer for around $10. To open the fob, you'll require a flathead screwscrew. The screwdriver's head must fit into tiny slots on the back of your fob. After you've removed the case and battery, you'll need to replace the old battery with a new one.
It's time to add the new key fob in your vehicle. To do this, insert the first working key into the ignition and turn it on. For about five seconds, then switch off the ignition. Repeat the process using a second working key, then your new (or spare) key. After you've done this then your Mazda should now be able started with the newly programmed keys. If not, it could be a problem with the key fob.
