What is a Keyless Entry System in Cars?

A keyless entry system is a modern innovation of technology that allows access to the vehicle without using traditional mechanical keys. This generally occurs through a remote fob, smartphone app, or proximity sensor communicating with the vehicle when the owner approaches. 

It uses wireless technology over a very short distance for communication using radio signals between the car and a remote. When you touch the button, a signal is transmitted. An electronic command sends a radio signal to unlock all the car doors and the boot, where applicable. Some systems also let you start the engine without inserting a key, a very convenient feature.

What are Traditional Car Keys?

Traditionally, car keys are the same ones that have been used for decades to unlock and enable a car's ignition. They usually consist of a metal blade that could fit into the door and then ignite the car as one inserts the key to operate or start the door. These keys are simple and easy to use. 

They have no batteries, which means there is no need for some electrical components to operate. Most older vehicles use conventional keys. While they do not match the flashiness of modern systems, traditional keys are known and positively popular. They have been around for a few decades and are useful for many car owners.
