Battery Replacement

Change the battery in the Mazda 3 key fob is an easy procedure that you can do at home. But, it is best to replace the battery when it fails, or when the key fob shows a message on the multi-information display saying, "Low key fob battery. Replace battery."

You'll need a flathead screwdriver and tape and patience to open the case. Put the flathead screwdriver's head in a notch, or gap on the bottom of the metal of the Mazda 3 key fob to take off the lower portion. Repeat this step for the top portion of the metal but be careful not to damage the rubber ring at bottom of the key fob's case.

There is a slot on both sides of the fob case that contains the battery. Use the tape-wrapped flathead screwdriver to gently the case open, beginning on one side before shifting to the other. Remove the old battery, and put in a new CR2025 and make sure it's facing up to ensure the correct orientation. Place the battery cap on again and attach both sides of your key fob case by pressing until they click.

Pairing Issues

This could be a sign that the transmitter in your car is damaged. It is typically a need for a professional to repair and will likely require a replacement key fob.

If you have tried replacing the battery and reprogramming the key fob but has not solved the problem, it is possible that the chip in the key fob is faulty. This can happen when the key fob was dropped on hard surfaces, exposed to salt water, or even touched by dirty hands.

You'll need an extremely small "key" that is inserted into the seam, to take off the circuit board and identify the problem. You will then be able to examine for any corrosion or damage on the chip. It is best to use a clean towel to keep the microchip from being damaged.

If you're not sure, you can also check the battery connector's terminals for cracks or breaks. If this is the case, soldering the terminals back to their place will usually restore functionality to the key fob. You can also check the buttons for wear or damage. If they are loose, they can be resoldered into place unless one has physically snapped.

Interference Signals

There is nothing more frustrating than staring at a "No Fob Detected" message when trying to start your vehicle. This usually occurs at the most awkward moments, such as the time you're late to work or picking up children from school/daycare. The good thing is that there are steps you can take to investigate the issue and determine the cause.

Interference signals can interfere with the remote key fob signal from the vehicle making it unable to work correctly. This can be caused by things like buildings, weather conditions and transmitters that operate on the same frequency. Interference can also occur when you have aftermarket equipment installed in the vehicle that transmits at the same frequency as the key fob.

The key fob might be damaged if it is exposed to water or salty water. The rubber seals on the electronic chip may be penetrated by water, particularly when it is submerged for long periods of time, such as in a pool or ocean at the beach. The chip can stop working and require replacement of the keyfob. If you have a programable 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 help the chip, it's likely fried and will need to be replaced.

Locking and unlocking of the Doors

The buttons on the key fob send electronic signals to a solenoid within the car, which converts the signal into a mechanical action that locks and unlocks doors. If the door lock doesn't work, it could be an issue with the solenoid. This will require expert auto repair shops to investigate.

A dead 12 volt battery can also stop the fob from functioning properly. This is the case if the battery's charge is lost, or if the contacts become corroded, and stop transferring electricity. This problem can be fixed in minutes with a new battery.

The receiver module could be the problem if the key fob isn't working after you replace batteries or reprogram the device. This device interprets radio frequency signals received by the key fob to control the vehicle. If it breaks down it could cost a lot to fix.

To verify if this is true, put your spare key in the key slot. Then, turn the ignition ON. Press the key fob twice for 10 seconds without taking it out. The Mazda 3 system will now synchronize the key with the car and allow you to use it as your primary remote for driving. This allows you to program up three keys.
