Keyless Remote Key Fob
Many modern cars have key fobs that allow you to remotely open and close the doors of your car and also start the engine. However, just like any other technology, these can fail from time to time. Thankfully, most issues with key fobs don't have to be complex or serious and are often easily fixed. Always keep a spare car key to avoid issues.
Key fobs require batteries that need to be replaced regularly. Some fobs have removable covers that make it easy to swap out the battery, while others may require a special tool or dealership assistance. A new battery is expected to last for around one year, irrespective of the type of fob you own. A spare battery can also aid in avoiding the stress of getting stranded in the middle of your way to work in Manhattan or White Plains.
Fobs that have "flip keys" include a key that flips out when a button is pressed, and the fob itself contains buttons for unlocking the door and opening the trunk etc. When not in use, the key can be turned into a remote. Flip keys and fobs can be vulnerable to damage due to various sources, including blunt force, water and circuit board scratches and excessive heat.
Transponder Chip Keys
You might require a transponder key to start your car if it is from the past two decades. This technology is designed to stop car theft through a signal that only the car's computer onboard can decipher. The key contains a tiny microchip in it that's similar to the chips used in military planes. The chip communicates with the vehicle's onboard system via a ringed antenna around the ignition cylinder.
The key has copper wiring attached to the microchip. It's this wire which transmits signals to the car's onboard computer when you turn it in the ignition. The computer onboard responds by allowing you to start the engine. If the code is valid, it will stay on and the vehicle won't shut off or unlock.
Some Mazda keys require programming (transponder and remote/fob keys). They are only programmed by a car dealer or automotive locksmith. Other keys do not require coding. For instance, regular metal keys without a chip do not need to be programmed.
Keys with Keyless Entry System
Mazda's Keyless Entry System allows you to unlock and start your car using just one keyfob. The key fob has a security chip built into it that emits a signal to the car's electronic system to trigger the doors and ignition. Some models also have a push button with a key that allows you to start the engine.

To keep the receiver and transmitter fully synchronized, a code of 40 bits is generated each time the keyfob button is press. The codes are generated by the receiver and transmitter by a pseudo-random generator to ensure that they do not repeat.
