G28 Car Keys of recent years come with key fobs which allow you to lock and open your doors from a distance as well as start your engine. However, like any other technology, they may malfunction from time to time. Fortunately, the majority of key fob problems aren't difficult or serious and can be fixed easily. One of the best ways to keep problems from catching you unaware is to always have a spare key.
Key fobs require batteries that need to be replaced regularly. Certain fobs have removable covers, which makes it easy to replace the battery. Others might require a specific tool or dealer assistance. A new battery can last for about an entire year, regardless of the type of fob you own. Having a spare battery can also aid in avoiding the stress of being stuck somewhere along the way to work in Manhattan or White Plains.
The "flip key" fobs have a key that can be flipped out when you press the button. The fob also has buttons to unlock the trunk, open the door and more. When not in use, the key can be flipped into the remote. Fobs and flip keys can be vulnerable to damage due to many sources, such as water, blunt force and scratches on the circuit board and excessive heat.
Transponder Chip Keys
If you have a car from the past two years or so, chances are that it will require an transponder chip key to start. This technology prevents car theft by using an encrypted code that can only be deciphered by the computer in the car. The key has a microchip similar to those used in military aircraft. The chip communicates with the vehicle's onboard systems via an antenna ringed around the ignition cylinder.
The key has copper wiring attached to the microchip. It's this wire that sends an electrical signal to the car's onboard computer when you turn the key in the ignition. The computer onboard responds by allowing the driver to start the engine. If the code is valid it will remain on and the car won't shut off or lock.
Some Mazda keys require programming (transponder keys and remote/fob keys). These are only programmed by an automotive locksmith. Other keys don't require coding. Other keys do not require any kind of code.
Keys for Keyless Entry Systems
Mazda's Keyless Entry system allows you to unlock your door and start your car using one keyfob. The key fob features a security chip built into it that transmits a signal the car's electronic system to trigger the doors and ignition. Certain models come with buttons that can be used to start the car with no key.

To keep the receiver and transmitter connected, a 40-bit number is generated each time the keyfob button is activated. The receiver and transmitter use an algorithm known as a pseudo-random numbers generator to generate the codes to ensure they don't repeat.
If you're experiencing issues with your Mazda Advanced Keyless Entry system It could be because the car's transmitter is not working or the battery in the fob isn't fully charged. Bring the key fob to Holiday Mazda in Fond Du Lac, WI to have a technician look at the issue. If you have a spare electronic key, bring it along too to use while you wait for your Mazda service center to fix the issue. Take the plate off 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.
Keys with Remote Control

You'll need to have the remote professionally programmed once received by an auto locksmith local to you (click here for Locksmith Search).

The key buttons control the door locks, liftgate lock, and the lid for the fuel-filler (if equipped) as well as start your vehicle's engine, and also activate the theft-deterrent systems if your vehicle is equipped with this feature. If the system malfunctions, the hazard warning lights and/or a warning tone will signal the issue. Contact your authorized Mazda dealer for more details.
