You can't predict everything. Especially your Mazda CX-7 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 CX-7 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 CX-7 key fob, use this battery finder by entering your year, make, and model. Mazda CX-7 remotes usually use a CR2025, CR2032, & CR1620 battery. Most key fob batteries cost less than $6 and are available for purchase online.
For newer Mazda CX-7s, insert the hidden key into a designated slot to open the case. For older Mazda CX-7s, 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 CX-7 key fob on our YouTube page. If you cannot find your specific Mazda CX-7 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 CX-7 key fob's battery does not resolve your issue, you may need to replace your Mazda CX-7 key fob entirely.
The extent of the damage to your Mazda CX-7 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 CX-7 key fob's case is damaged but the internal electronics are fine, you can easily replace the case. The availability of Mazda CX-7 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 CX-7 key fob entirely.
A replacement Mazda CX-7 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.
