Keyless entry car remote

It was in 1982 when the car manufacturer of the Renault Fuego introduced the first keyless entry to the American market. Since then, this feature is common to most car models in the US because of its benefits in terms of security and convenience. As the name of the system implies, keyless entry means that you do not have to use your key to lock or unlock the doors of your vehicle. It includes a keyless entry remote transmitter that lets you do the locking and unlocking within a set distance. This feature is especially helpful for those with kids, allowing them to get in the car independently and quickly.

Keyless entry car remote mechanism

A keyless entry car remote will only work on the one or two vehicles that it was linked or programmed to. You cannot use it for every car, even if their system is similar, because each remote transmits a signal through a specific frequency or code. Then the module or receiver installed in the vehicle receives that signal, which will either lock or unlock the doors.

As the technology advances, the mechanism changes and becomes better. There is another type of keyless entry that does not require you to press any button to enter your car. All you need to do is to program the remote car system so that the doors will automatically unlock whenever you are five feet from your car.

Advantages of using keyless entry

  • Convenience in unlocking or locking the car doors without fitting the car keys into the lock
  • Quicker entry for everyone getting into the car without having to unlock each door one by one
  • Convenience in locking and unlocking the door within the range sometimes even if the remote holder is inside the home or building
  • When the driver forgot to lock the doors or not sure if they have locked them, the driver can simply press the buttons to double check even if they are feet away from the car
  • When someone has to load or unload equipment or groceries faster, it is easier to open and close the car doors without keys

Different kinds of keyless entry system

Programmable keypad system

Simply put, this system allows you to enter the car without a key. However, you have to type the passcode on the keypad near the car’s handle. This type is one of the earliest types of keyless entry system. Some pass codes are pre-programmed by the manufacturer while others allow you to program your own passcode so that only you will know.

Key fob system

In this system, you have more options aside from lock and unlock buttons. Another thing that you can do is to open the trunk by pressing the trunk release. This comes in handy when you have to load or unload things. Some brands with this kind of system also come with an alarm button and a remote start for the ignition. Each press of the button or buttons has a corresponding value. For example, one press means that the system will unlock the driver’s door, while two presses unlock all the doors. Meanwhile, there is a separate fob for the trunk release. This system is distance dependent; in other words, the transmitter will only work within the range of distance.

Smart key system

The smart key system sometimes does not require the use of a traditional key at all. Instead, the car keys look like a transmitter that is as small as the size of a credit card. Depending on the program, this system allows you to access your vehicle without keys or pushing any button. When you walk near the car, the doors will automatically unlock. Just make sure that you are holding the transmitter so that the module in the car will sense the transmitter or transceiver. When you are ready to drive the car, you do not need to insert the key into the ignition. All you have to do is to push a specific button.

Another thing that makes this system smart is that it allows you to program additional features for your optimal convenience. You can program seat adjustments, radio station, as well as the speed limit of the car. Parents, for example, will find this beneficial because they still have overall control of the vehicle when they let young drivers drive their car.
