You can't predict everything. Especially your Mazda 3 key fob suddenly not working, breaking, or getting lost on a day when time is short. When that happens, Keyless Entry Remote is there to help you find a solution.
Use this guide to learn how to replace your Mazda 3 key fob's battery and what to do when you've lost or damaged your remote.
A dead battery is the most common reason a remote stops working. To find the correct replacement battery for your Mazda 3 key fob, use this battery finder by entering your year, make, and model. Mazda 3 remotes usually use a CR2032, CR2025, & CR1620 battery. Most key fob batteries cost less than $6 and are available for purchase online.
For newer Mazda 3s, insert the hidden key into a designated slot to open the case. For older Mazda 3s, use a thin object (like a flathead screwdriver) to pry open the case at the notch. After opening the case, gently lift the circuit board to access the battery. Before removing the battery, note how it fits in the case. Next, replace the old battery with the new one and close the case. Test your key fob's functionality by pressing buttons to ensure it is working properly. If it doesn't work, adjust the battery by ensuring the connections are clean and in contact with the battery.
To see step-by-step video instructions on replacing your remote's battery, search for your Mazda 3 key fob on our YouTube page. If you cannot find your specific Mazda 3 key fob, you can find a video showing the battery replacement process of a different remote that is the same type as yours.
If changing your Mazda 3 key fob's battery does not resolve your issue, you may need to replace your Mazda 3 key fob entirely.
The extent of the damage to your Mazda 3 key fob will determine your options.
A damamged key blade means you need to order a new, uncut key blade and have it cut. To cut your key blade, seek out trusted automotive professionals, such as the ones found here on our Locksmith Locator page.
If your Mazda 3 key fob's case is damaged but the internal electronics are fine, you can easily replace the case. The availability of Mazda 3 key fob cases cannot be guaranteed. If you don't mind not having a logo, you can try aftermarket cases.
If your remote is damaged beyond the key blade or case, then you may need to replace your Mazda 3 key fob entirely.
A replacement Mazda 3 key fob is the only solution to a lost or severely damaged remote. Brand-new replacements can cost you $200 or more. A used, refurbished key fob is a more cost-effective option.
After you purchase your replacement Mazda 3 key fob, your next 2 steps are figuring out how you are going to program your remote and finding an automotive professional to cut the key blade. Some key fobs are easy to program by yourself, but others require an automotive locksmith.
To find out whether you can self-program your Mazda 3 key fob or need help, look up your key fob programming instructions here. If you do need an automotive professional, find a trusted locksmith on our Locksmith Locator page.
