What is the difference between keyless entry and remote keyless entry?
Keyless entry and remote keyless entry are two distinct technologies used to unlock and access vehicles, each with its own unique features and capabilities. In this article, we'll explore the key differences between these two systems to help you understand which one might be the best fit for your needs.
Keyless Entry
Keyless entry is a basic system that allows you to unlock your vehicle's doors without using a physical key. It typically involves a button or switch located on the vehicle's door handle or near the driver's side door. When you press the button, it sends a signal to the vehicle's electronic control unit, which then unlocks the doors. Keyless entry systems are a simple and convenient way to access your vehicle, but they do not offer the same level of functionality as remote keyless entry systems.
Remote Keyless Entry
Remote keyless entry, on the other hand, is a more advanced system that allows you to control various vehicle functions from a distance using a handheld remote control or key fob. In addition to unlocking the doors, remote keyless entry systems can also be used to lock the doors, open the trunk or hatchback, and in some cases, even start the engine. The remote control typically has several buttons, each with a specific function, and it communicates with the vehicle's electronic control unit using radio frequency (RF) or Bluetooth technology.
Key Differences
- Range: Remote keyless entry systems typically have a longer range than keyless entry systems, allowing you to unlock and control your vehicle from a greater distance.
- Functionality: Remote keyless entry systems offer more advanced features, such as the ability to start the engine, open the trunk, and control other vehicle functions, while keyless entry systems are limited to unlocking the doors.
- Security: Remote keyless entry systems are generally considered more secure than keyless entry systems, as they use encrypted signals to communicate with the vehicle, making it more difficult for thieves to hack into the system.
- Power Source: Keyless entry systems are typically powered by the vehicle's electrical system, while remote keyless entry systems use a battery-powered remote control or key fob.
In summary, while both keyless entry and remote keyless entry systems provide a convenient way to access your vehicle, remote keyless entry offers a more advanced and feature-rich experience, with the ability to control a wider range of vehicle functions from a distance. The choice between the two will depend on your specific needs and preferences.
