Pairing Issues

This could mean that the transmitter in your car has been damaged. This is usually a matter that requires a professional. You will require a brand new key fob.

If you've attempted to replace the battery and reprogramme the key fob, but it hasn't worked it is possible that the chip inside the key fob could be defective. This could happen if the key fob has been dropped on hard surfaces, exposed to salt water, or even touched by dirty hands.

You'll need the small "key", which is inserted into the seam, to take off the circuit board and identify the issue. Then, you will be able to check for any corrosion or damage on the electronic chip. It is recommended to use a clean paper towel to avoid damaging the microchip.

If you're unsure, you can also check the battery connector's terminals for cracks, or breaks. If this is the case, then carefully connecting them back can generally restore the functionality of the key fob. Additionally, you can look at the buttons to see whether they're worn or damaged. If the buttons are loose they can be soldered back into place, unless one has physically snapped.

Interference Signals

There is nothing more frustrating than looking at an "No Fob Detected" message when you attempt to start your car. This typically happens at most inconvenient moments, like when you're running late for work or picking up children from school/daycare. The good news is that there are a few steps you can take to troubleshoot the issue and determine what is causing it.

Interference signals can affect the remote key fob's signal to the vehicle making it unable to function correctly. This can be caused by objects like weather conditions, buildings, and transmitters that use the same frequency. Interference can also occur if you install aftermarket equipment in the vehicle that transmits at the same frequency as the key fob.

Additionally, if the key fob is exposed to salt or water it may be damaged. The rubber seals on the electronic chip can be penetrated by water, particularly in the event that it is submerged for an extended period of time, such as in a swimming pool or at the beach. The chip may cease to function and may require replacement of the keyfob. If you have a key which can be programmed, you can clean it with isopropyl and electronic cleaners to bring it back to its original functionality. If this doesn't work then it's likely that the chip has fried and will need to be replaced.

Locking and Unlocking of Doors

The buttons on the fob's key send electronic signals to the solenoid of the car, which then transforms this signal into a mechanical action. This locks and unlocks doors. If the door lock isn't working, the problem could be a solenoid malfunction that requires some analysis with the help of a professional auto repair shop.

A dead 12 volt battery could also hinder the fob from working properly. This could happen if the battery's charge is lost or the contacts are corroded and stop transmitting electricity. The good news is that a new battery is able to fix this problem in just minutes.

The receiver module could be the problem if the key fob isn't working after replacing batteries or reprogram the device. The device interprets radio frequency signals sent by the key fob to control the vehicle. It could be expensive to repair if it is damaged.

To verify 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 will now be able to synchronize the key with your car, and you can use it as your primary remote for driving. You can program up to three keys this way.
