Remember when, in the 80's, we were so excited about the number pads on the car doors so we could enter the car just by entering some combination of numbers...not by using our key? Well, with today's technology, we now have keyless entry remote systems on cars, not just luxury cars but for many different types of cars.
Keyless entry remote is often found on the luxury cars as with a click of the button, the car is armed and other security features are activated. All of the insurance companies love them since the high-tech security systems that come with these expensive autos are armed without much thought required by the drivers. Police departments love them, because many of the keyless entry systems come with a 'low-jack' feature to track stolen cars.
If the car is touched, jiggled, moved or an attempt is made to enter without the system being disarmed, lights will flash and the horn will sound - loudly. We are all familiar with the car in the parking lot starting to make loud noises, with seemingly no one around. We chuckle at the noise, but we all check to make sure it is not our car that is being 'attacked'.
These car alarm systems work by broadcasting radio waves from your remote system to your car. You can unlock your car before you get to it. The keyless entry is safer for women as you can unlock just the driver's side door or all the doors with your remote button; hence the name keyless entry remote system. It is much more useful than the above mentioned number pad, with one touch of a button you can unlock the vehicle from around thirty feet.
If you are carrying a young child, or bags of grocery, being able to press a button and have the car doors unlock, the trunk opened or, with some systems, a door open, the keyless entry remote system can be a life saver.
Keyless entry systems also have advanced features like remote starting. Having the engine running while the car is still locked can be extremely helpful. If you live in an area with bad winter weather, having the car start warming up before you leave your house or get to the car from the office, is very nice. Or, if you live in the dessert like I do, where summer temperatures are frequently over 110 degrees, which means the inside of the car is way over two hundred degrees after being parked in the sun for just a little while. So, when you can start the car and turn on the air conditioning before you get in the car that's a big deal. Just imagine opening the door and sliding in behind the wheel and being able to touch the wheel when before the keyless entry remote system, you were unable to touch the steering wheel for 2-3 minutes after you physically start the A/C.
An important part of the system is the key fob which holds the transmitter component of the remote system. Without the programmed key fob, there would be no emitted signals to lock or unlock the vehicle.

Some of the fobs now have chips embedded in the key itself that completes the ignition sequence and allows the car to start. Accordingly, this 'luxury' keyless entry remote system has become more than a convenience and expanded into a security factor.
