Overview of Keyless Ignition Systems
Overview:
Keyless ignition systems work by replacing the ignition switch in a vehicle with an electronic device commonly referred to as a radio frequency identification (RFID) module. There is one component of the RFID system inside the ignition circuit of the car, and another in a key fob carried by the owner. The two RFID devices have to communicate with each other before the car can start. In standard start systems, the ignition key trips a relay, which in turn supplies power to the starter motor. In a remote start vehicle, the relay is tripped only when two conditions prevail. These are:
1) The remote RFID key fob carried by owner comes within 20 feet of the car, and
2) The driver presses the push-button start.
The (vastly oversimplified) diagram shows the three possible conditions.
A. The key fob is more than 20 feet away from the RFID device inside the car. The ignition relay is open, and the push-button start is open.
B. The key fob communicates with the RFID device in the car when it is less than 20 feet away, but the push-button is not depressed.
C. The key fob is within range, AND the driver presses the start button.
The RFID modules communicate by way of encrypted signals, in order to provide security.

Smart Auto Features for Older Drivers
“Smart Features for Mature Drivers” is a great tool to help seniors evaluate a vehicle, by focusing on the different features that address age-related problems. Here are some of the features they recommend you look for, depending on what ails you: . . .
Arthritic hands: Drivers who have hand or wrist arthritis or a weak upper body can benefit from thick steering wheels which are easier to grip, keyless entry and ignition that eliminates twisting and turning, power mirrors and seats that are easy to operate, larger dashboard controls with buttons versus knobs that are easier to manipulate, and four-door models versus two-door cars which have longer heavier doors that are harder to open.

Inside, this Mazda’s look is similarly one of modernity and sophistication. A quantum leap forward from the outgoing model, the 6’s furnishings now rank up at the top of the segment for material quality, panel fit, and feature count.
A large starter button is mounted uncharacteristically low in the center stack, but at least Mazda has finally jettisoned its ridiculous keyless credit-card access system in favor of a more traditional fob.

We’re beyond the stage of “golly gee” for push-button starting. This one appears to be a version of that provided by one-time corporate partner Mercedes-Benz, but the ignition is one step from being that Keyless-Go innovation. There is no ignition key. The unlock and start sequence requires the driver to use the remote to unlock the door, then, once inside, to hit the starter button. The complete (Mercedes) system recognizes the key fob carried by the driver and unlocks the door as the driver grasps the door handle. Then the driver can hit the starter, belt up and bolt.

What is a Keyless Entry System?
What is a keyless entry system?
Vince Migliore
August 12, 2008
In its most basic form, a keyless entry system is a technology that allows a person to gain access to anything that is locked up, where the “lock” does not use a traditional key. Instead, the property, such as a car, is rendered inoperable until such time as the owner comes within a few feet while in possession of a device that remotely allows access.
The most common form of a keyless system is the ignition systems found in some high-end automobiles. The technology works by placing a Radio-Frequency IDentification (RFID) transponder in the vehicle’s ignition system. A relay, or switch, prevents the car from starting. When the owner comes within the vicinity of the car carrying a passive RFID device, the transponder recognizes the legitimate owner, and unlocks the system. The owner then simply presses a push button to start the car. When he leaves the vicinity, the car locks itself again automatically.
Although the luxury cars are the most popular form of keyless systems, the technology is now being applied to other kinds of vehicles, home security systems, business alarm systems, and even computer security devices.
The major advantage for consumers is convenience – no fishing around for keys – and security – as the system prevents theft and is often complimented by an alarm system. Many industry experts expect these advantages to translate into much wider use of keyless entry systems.
