You will need to locate an extremely small “key”, which is inserted into the seam, to take off the circuit board to identify the issue. Then, you will be able to examine for any damage or corrosion on the electronic chip. It is best to use a clean towel to avoid damaging the microchip. You may also inspect the battery connector's terminals to determine if they're cracked or broken. If this is the case, carefully attaching them back will usually restore the function of the key fob.

If you have a key that can be programmed, you can clean it with isopropyl or electronic cleaners to restore its function. If this doesn't help the chip, it's likely to be fried and will require to be replaced. Locking and Unlocking of Doors The buttons on the fob's key send electronic signals to the solenoid in the car, which then transforms the signal into mechanical action. This locks and unlocks 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 low-voltage battery can also prevent the fob from functioning properly. This could happen if the battery loses charge or the contacts are corroded and stop transmitting electricity.

The Mazda 3 system synchronizes the key with the vehicle and you can use it as your primary remote for driving. You can program up to three keys in this way.
