Find a gap or notch in the bottom part of the metal of the Mazda 3's key fob, and then insert the head of the screwdriver in it to break off the lower half. Repeat the process for the top metal piece, but be careful not to damage the rubber ring on the bottom of the key fob's case.

Pairing Issues
If your key fob has stopped working all of a sudden it could be a sign that the transmitter inside your car is damaged. This usually requires an expert repair and will likely need a new key fob.
If you've tried replacing the battery and reprogramming the key fob, but has not solved the problem, it is possible that the chip inside the key fob might be defective. This can happen when the key fob has been dropped on hard surfaces or exposed to saltwater or even brushed by dirty hands.
To determine the cause, you will need to find a small "key" that is embedded into the fob's seam which allows you to lift it open and take out the circuit board. Then, mazda 3 keys can examine the chip for damage or corrosion. It is best to use a clean towel to avoid damaging the microchip.
If you are unsure then you should also examine the battery connector's terminals for cracks or broken. If this is the case, carefully soldering them back in place can generally restore the functionality of the key fob. Additionally, you can look at the buttons to determine whether they're worn or damaged. If the buttons are loose they can be resoldered into position, unless they've physically snapped.
Interference Signals
There are few things more frustrating than looking at a "No Fob Detected" message when trying to start your car. It happens at the worst time, for instance when you're running late to work or pick up your children from school/daycare. The good thing is that there are a few steps you can take to troubleshoot the issue and determine what is causing it.
Interference signals can disrupt the remote key fob's signal to the vehicle making it unable to work correctly. This could be due to objects such as weather conditions, buildings, and transmitters using the same frequency. Interference can also occur when you have equipment from an aftermarket manufacturer installed in the vehicle that transmits on the same frequency as the key fob.
The key fob could be damaged if exposed to water or salty water. Water can get into the rubber seals of the electronic chip particularly when the key fob is submerged in water for a long duration. The chip may cease to function and require replacement of the keyfob. If you have a programmeable key it is possible to clean the chip with isopropyl alcohol or an electronic cleaner to help it get back to its original functionality. If this doesn't help the chip, it is likely to be fried and will require to be replaced.
Locking/Unlocking of the Doors
The buttons on the key fob send electronic signals to a solenoid within the car, which transforms the signal into a mechanical action that locks and unlocks doors. If the door lock isn't working it could be due to an issue with the solenoid. This requires professionals from auto repair shops to investigate.
A dead 12 volt battery can also prevent the fob from functioning correctly. This can occur if your battery fails to charge or if your contacts become corroded. This problem can be fixed in just a few minutes by purchasing a new battery.
If the key fob won't work after you have changed the battery or program it again the problem could be related to the receiver module. The device receives radio frequency signals from the key fob and interprets them to control the functions of the vehicle. It could be a costly repair if it becomes faulty.
To determine if this is true, put your spare key in the key slot. Then turn the ignition ON. Press the key fob two times in a period of 10 seconds, without taking it out. The Mazda 3 system will now synchronize the key with the vehicle and you can then use it as your primary remote for driving. This lets you program up to three keys.
