Battery Replacement You can replace the battery on your Mazda 3 keyfob at home. But, mazda 3 replacement key should only replace the battery when it dies, or if the key fob shows a message on the multi-information display, “Low key fob battery. Replace battery.” You'll need an flathead screwdriver along with tape and patience to open the case. Find a gap or notch in the bottom metal part of your Mazda 3's key fob, and then insert the tip of the screwdriver in it to break off the lower half. Repeat the process for the top portion of the metal, but be careful not to scratch the rubber ring at bottom of the key fob's case.

Pairing Issues If your key fob stops functioning suddenly it could be a sign that the transmitter in the car is damaged.

If you have tried replacing the battery and reprogramming the key fob, but this does not solve the issue, it is possible that the chip in the key fob may be malfunctioning. This can happen if the keyfob has been dropped, exposed to saltwater, or touched by dirty fingers. To diagnose this issue You will need to locate a small “key” embedded in the seam of the fob that allows you to take it apart and take out the circuit board. Then, you will be able to check for any corrosion or damage on the electronic chip. It is recommended to use a clean towel to ensure that the chip is not damaged. It is also possible to take a close look at the battery connector's terminals to determine if they're damaged or cracked. If this is the case, then carefully reconnecting them can generally restore the functionality of the key fob. In the same way, you can examine the buttons to determine whether they are worn out or damaged. If the buttons are loose, they can be soldered back to their original position unless they have physically snapped. Interference Signals There's nothing more frustrating than trying to start your car only to see the message “No Fob Detected”. This usually occurs at the most awkward times, such as when you're running late for work or when you are picking up your children from school/daycare. The good news is that there are steps you can take to troubleshoot the issue and figure out the root of the problem. Interference signals can disrupt the remote key fob's signal from the vehicle, causing it to not function correctly. This could be caused by objects like weather conditions, buildings, and transmitters that use the same frequency. Interference could occur if your vehicle is equipped with aftermarket equipment that transmits at the same frequency as your key fob. The key fob may also be damaged if it is exposed to salt water or water. Water can penetrate the rubber seals of the electronic chip particularly when the key fob has been submerged in water for a prolonged duration. The chip could stop working and may require replacement of the keyfob. If you have a programmable key you can clean the chip with isopropyl alcohol or an electronic cleaner to aid in its get back to its original functionality. If this doesn't work you can be sure that the chip has fried and needs to be replaced. Locking and Unlocking the Doors The buttons on the key fob send electronic signals to the solenoid inside the car, which converts the signal into mechanical action. It locks and unlocks doors. If the door lock is not working, it could be due to a solenoid problem that requires some investigation with the help of a professional auto repair shop. A dead battery of 12 volts can also stop the fob from functioning correctly. This is the case if the battery's charge is lost, or if the contacts become corroded and stop conducting electricity. This issue can be solved in just a few minutes by purchasing a new battery. If the key fob isn't functioning after you change the battery or reprogram it the issue could be with the receiver module. The device interprets radio frequency signals received by the key fob to control the vehicle. It can be a costly repair if the device becomes defective. To test if this is true, insert your spare key in the key slot. Then turn the ignition on. Press the key fob twice for 10 seconds without removing it. The Mazda 3 system synchronizes the key to the vehicle and you can now use it as your primary remote for driving. You can program up to three keys this manner.
