It is best to first call their local Mazda dealership or locksmith. This is a good idea for a variety of reasons, and it's likely to be less expensive and quicker than calling a tow-truck.

This will usually activate the danger warning lights and emit a signalling that the doors, fuel-filler lid, or liftgate are closed.

Transponder Chips

The antenna ring emits a burst radio frequency energy when you insert your key in the metal and turn it on. The energy reaches the chip's transponder located in the key. The chip then responds with an identifier that is transmitted to the antenna ring telling the car that it's a valid key.

Most Mazdas utilize 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 will never work on your vehicle until you've got a duplicate with the same exact code in the ignition cylinder.

It's possible to create your own replacement keys. If you're able find an original key, insert it into your Mazda and set the ignition to ON. You can copy the data from the key to the second key in case it starts your Mazda. If you need to, you can also make use of 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 may not respond correctly.

Programming

This can be done in just a few steps, and you don't need to pay an agent for this service. You will not have to pay for towing charges or dealership fees if there is an extra car key.

You'll first need to purchase new batteries for the key fob. You can purchase one at a big box store or at a hardware store for approximately $10. To open the fob, you'll require an screwdriver with a flat head. The screwdriver's tip should fit into small slots on the side of the fob. After removing the case, replace the old battery.

Now you can program your new key fob. To do this, put the working key into the ignition and then turn it ON. Then, wait for five seconds and then turn the ignition off. Repeat the process using another key that works, and then your new (or extra) key. Once you've done this, the newly programmed key should be in a position to start your Mazda. If it doesn't then there could be a problem with the key fob or the vehicle.
