Read on for more information about the process and your options for getting a new Mazda key.
Types of Mazda Keys Available
The type of Mazda fob you can buy depends on the model and year of your vehicle.
For example, a 2021 Mazda CX-5 is likely to use advanced technology and be compatible with keyless entry. However, if you have a car from many decades ago, it will likely need a traditional blade.

If your Mazda model is older than 2021, you may find that you need this type of fob to open your car. The price of this option is usually lower than that of a Mazda key fob.
Even though this remote does not have the same button functions as other fobs, it is still useful. You insert it into your side door lock, and it allows you to enter your vehicle.
Keyless Entry Remote
A keyless entry remote opens your car through the process of pushing a button. As well as the ability to unlock, it can contain other tools like a panic alarm. Just press the button to call for help.
Some keyless entry remotes also come with an emergency replacement transponder key. Even if your remote technology goes dead, you are still able to enter your vehicle. Just remove the key and insert it to unlock.
Intelligent Smart Key Remote
An intelligent smart key remote is similar to a keyless entry remote. However, the advanced technology allows you not just to unlock but start your Mazda.
The price of this kind of key will be slightly more than the other options. It usually works with more advanced cars, like a 2021 Mazda CX-5.
If you’re unsure which remotes are compatible with your vehicle, you should contact your local Mazda dealer.
They will likely tell you to “call us” and provide you with detailed information about your car and its parts.
