Keyless Remote Key Fob

Some cars are equipped with key fobs that allow you to open and lock the doors of your car remotely, as well as start your engine.

Batteries are required for key fobs, and they have to be replaced on a regular basis. Some fobs have removable covers, which makes it easy to replace the battery. Others may require a special tool or assistance from the dealer. No matter what kind of key fob you own the battery you replace it with should last for about a year. A spare battery can save you from being stranded on the way to work in Manhattan, White Plains or elsewhere.

The "flip key" fobs have the flip-out key that pops out when you press a button. The fob also comes with buttons to unlock the door, open the trunk, etc. The key can be reversed back into the remote when being used. Flip-keys and fobs can be damaged by a number of things, such as water and blunt force. Scratches to the circuit board and excessive heat are also a possibility.

Transponder Chip Keys

If you own a vehicle dating back to the last two decades or so, the chances are that it requires a transponder chip for start. This technology is designed to stop car theft by using signals that only the car's computer onboard can detect. The key is equipped with a tiny microchip inside it which is similar to the chips used in military aircraft. The chip communicates with the vehicle's onboard computer system via an antenna that is a ringed cylinder.

The key's copper wiring is connected to the microchip. This wire transmits a message to the onboard computer of the car when you turn the key into the ignition. The computer responds by allowing you start the engine. If the code is valid, it stays on and the car won't shut off or lock itself.

Certain Mazda keys need programming (transponder and remote/fob keys). These keys can only be programmed by an auto dealer or automotive technician. Certain keys do not require the use of coding.

Every time the keyfob is pressed, a 40 bit code is generated to keep the transmitter and the receiver in sync. The codes are generated by the receiver and transmitter using a pseudo-random generator, so that they don't repeat.
