Pairing Issues
This could mean that the transmitter inside your car may have been damaged. It is typically a need for an expert to repair it and will likely require a new replacement key fob.
If you've attempted to replace the battery and reprogram the key fob, but it's not working it is possible that the chip inside the key fob could be faulty. This can happen when the key fob has been dropped on hard surfaces, exposed to salt water or even brushed by dirty hands.
To determine the cause You will need to locate a small "key" embedded in the fob's seam that lets you lift it open and take out the circuit board. Then, you can check the electronic chip for damage or corrosion. To avoid damaging the chip, it is best to use a fresh paper towel.
If you aren't sure you are not sure, you can check the battery connector's terminals for cracks or broken. If this is the situation you can solder the terminals back into place can usually bring back functionality to the key fob. You can also inspect the buttons for damage or wear. If the buttons are loose, they can easily be soldered back in place as well unless the button is physically snapped off.
Interference Signals
There are few things more difficult than trying to start your vehicle and getting the message "No Fob Detected". This happens at the worst situations, like when you're late to work or pick up your children from school/daycare. The good news is that there are a few steps you can take to investigate the issue and figure out the root of the problem.
Interference signals can cause the remote key fob to stop working properly. This can be caused by objects like weather conditions, buildings, and transmitters that operate on the same frequency. Interference may also occur if you have an aftermarket device installed in the vehicle that transmits at the same frequency as the key fob.
Additionally, if the key fob is exposed to salt or waters, it could be damaged. The water can penetrate the rubber seals of the electronic chip particularly when the key fob is submerged in water for an extended duration. This can cause the chip to stop functioning and require replacement of the key fob. If you have a key which can be programmed to work, you can clean it with isopropyl or electronic cleaners to bring it back to its original function. If this doesn't help, it is likely that the chip is fried and requires replacement.
Locking and Unlocking of Doors
The buttons on the keys send electronic signals to the solenoid inside the car, which transforms the signal into a mechanical action that locks and unlocks the doors. If the door lock doesn't work it could be because of an issue with the solenoid. This requires professionals from auto repair shops to examine.
A dead battery of 12 volts can also prevent the fob from functioning properly. This could happen if the battery loses charge, or if the contacts are corroded and stop transmitting electricity. The problem can be addressed in a matter of minutes by replacing the battery.
The receiver module may be the reason why the key fob doesn't work after replacing batteries or reprogram the device. The device receives radio frequency signals from the key fob and interprets them into controlling the vehicle's functions. If it malfunctions, it can be expensive to repair.
To check if this is the case, start by putting your spare key into the key slot and setting the ignition to ON. Press the key fob button two times within 10 seconds, without removing it. The Mazda 3 system will now sync the key to the car and you can use it as your primary remote for driving. You can program up to three keys this way.
