Types of Keyless Entry Autos

Keyless entry auto allows car owners to access their vehicles without traditional keys. This system provides convenience and security for both car owners and business retailers. The keyless entry system has two main types, which are as follows.

• Key fob entry

  Key fob entry systems use remote controls called key fobs. The key fobs send low-frequency signals to the car's computer. When the car owner approaches the vehicle, the computer detects the signal and unlocks the doors. Car owners can also press a button on the key fob to unlock the doors. This system is common in most modern cars. It provides convenience, especially for families with kids. Parents can unlock the trunk to load groceries while their kids are playing nearby. The key fob entry system also enhances security by preventing unauthorized entry. Some key fob entry systems allow customization. Car owners can program the key fob to perform specific functions, like opening a particular trunk section or activating a security alarm.

• Proximity key entry

  Proximity key entry systems, also known as smart key systems, are more advanced than key fob entry systems. In this system, the key fob always sends a signal to the car. The driver can unlock the doors, open the trunk, or start the engine by pushing buttons while the key fob is in their pocket or bag. This system offers touchless convenience. Drivers don't have to fumble with the key fob to unlock the doors or start the engine. They can do all that with a few touches. Proximity key entry systems are beneficial for people with disabilities or the elderly. They provide accessibility features like adjustable seats and audio feedback.
