To determine the cause of the issue You will need to find a small "key" built into the fob's seam that lets you lift it open and remove the circuit board. Then, you will be able to check for any damage or corrosion on the chip. It is recommended to clean the paper towel to keep the microchip from being damaged.

Interference signals can cause the remote key fob to stop working in a proper manner. This can be caused by things such as weather conditions, buildings, and transmitters that use the same frequency. Interference may occur if your vehicle has aftermarket equipment that transmits at the same frequency as your key fob.

In addition, if the key fob is exposed to water or salt water it may be damaged. Water can get into the rubber seals of the electronic chip, particularly in the event that the key fob is submerged in water for a long period of time.

If you have a key which can be programmed to work, you can clean it using isopropyl or electronic cleaners to bring it back to its original function. If this does not help the chip, it is likely to be damaged and will need to be replaced.

Locking and Unlocking the Doors

The Mazda 3 system synchronizes the key to the vehicle, and you can now use it as your primary driving remote. This allows you to program up to three keys.
