The remote entry keys have made life easy for all modern day drivers. 

Working

It’s a small battery operated device that completely eliminates the need of physical car keys.  Its working is exactly like a television-set remote or any other remote.  These keyless remotes have been around for some time but have actually picked up in the 1990s. 

Advantages of Keyless Remotes

The biggest advantage is of course its keyless entry function.  All you have to do is press a button on the little panel in your hand and you can operate your cars doors.  It comes equipped with a car alarm system which prevents unauthorized entry.  The trigger mechanism sets off a loud alarm.  Some have added features like mute key, garage door open key, controlling the windows etc.

Security

This is an added security feature for which you don’t have to pay any extra money.  Moreover, if you are out late at night or in a dark area you can open the door of the car with your remote entry key while still from a distance; not having to wait to actually reach the door and fumble in the dark for a physical key. This saves you precious time, thus enhancing your safety.
All in all, it’s a must have for every car owner.
