Keyless Remote Control Fob
Many of the latest cars have key fobs that permit users to remotely open and lock the car's doors and even start the engine. However, like any other piece of technology, these can fail from time to time. Fortunately, the majority of key fob issues are not difficult or serious and can be easily resolved. One of the best ways to keep problems from catching you unaware is to always have a spare key.
Batteries are required for key fobs and have to be replaced frequently. Some fobs have removable covers that make it simple to swap out the battery, while others may need a special tool or dealership assistance. A new battery should last for about one year, irrespective of the kind of fob you have. A spare battery will assist you in avoiding the stress of becoming stranded in the middle of your way to work in Manhattan or White Plains.
Fobs that feature "flip keys" include a key that flips out when the button is pressed and the fob also has buttons for unlocking the door or opening the trunk etc. The key portion can be turned back to the remote when it is not being used. Flip keys and fobs could be susceptible to damage from many sources, including blunt force, water scratching on circuit boards, and excessive heat.
Transponder Chip Keys
If you have a car from the past two years or so, chances are that it requires a transponder chip key to start. This technology is designed to stop theft of cars by utilizing a signal that only the car's onboard computer can decipher. The key has a small microchip inside which is similar to the chips used in military planes. The chip communicates with the vehicle's onboard system through a ringed antenna around the ignition cylinder.
The key also has copper wiring connected to the microchip. This wire transmits a signal to the onboard computer of the car when you turn the key in the ignition. The computer responds by allowing the engine to start. If the code is valid, it will stay on and the vehicle won't shut off or lock.
Some Mazda keys need programming (transponder and remote/fob key). These keys can only be programmed by an auto dealer or automotive technician. Other keys aren't required to be programmed. Other keys don't require coding.
Keys for Keyless Entry Systems

Mazda's Keyless Entry System allows you to open and start your vehicle using just one keyfob. The key fob is equipped with a security chip which transmits a signal to the car electronics to activate doors and ignition. Some models also have an unlocked key to start the engine.
To keep the transmitter and receiver synchronized, a 40-bit code is generated each time a keyfob button is press. The receiver and transmitter utilize a pseudo-random generator to generate the codes to ensure they don't repeat.
If you're experiencing problems with your Mazda Advanced Keyless Entry, it could be because the fob battery is low or the transmitter inside your car is malfunctioning. If the issue isn't resolved then bring the key fob to Holiday Mazda in Fond du Lac, WI, to have the technician look. Bring a spare remote to use while you wait for your Mazda dealer. Also, remove the plate attached to the key set and put it in a safe location (not in your vehicle). This will provide you with the key code you must use to replace the keyfob.
