Understanding Remote Keyless Systems: Working & Benefits

Modern technology is elevating not just how we cruise in our cars but also how we access them. One key advancement is the remote keyless systems, which are not only used for vehicles but also for homes and commercial properties.

By the powers of a key fob, this entry system gets rid of physical skills, giving you remote access—getting curious?

Let’s explore how RKS works and its many important benefits.

What is a Remote Keyless System?

A remote keyless system is exactly what it sounds like: no physical key. You only need a key fob in your pocket to lock and unlock your car’s door. This differs from a remote keyless ignition system, which controls the engine’s start-up. While these modern systems offer convenience and enhanced security, it’s still important to have access to professional key cutting services in case a replacement or backup key is ever needed.

Here are the basic components of a remote keyless system:

• Key fob: a small electronic device that sends signals
• Receiver: captures the signal and alarms the vehicle
• Control module: authenticates the signal and activates the car

How Do Remote Keyless Systems Work?

Radio Frequency Identification is a wireless communication that uses radio waves to tag objects automatically. RFID is the technology behind RKS.

As such, when the key fob is nearby, the receiver detects the signal and transmits the data via electromagnetic fields. This data is then communicated to the system from the fob, triggering the action.

To prevent hacking, the remote keyless system employs two important security measures.

• Rolling codes: A new security code is generated every time the remote control is used. This prevents the transmission from being recorded and played back later to deceive the receiver into unlocking the door.

• Encryption: This protects the transmitted data using special codes only the car owner can understand.

Benefits of Remote Keyless Systems

Convenience

With RKS, you can unlock and lock your car door effortlessly, with just the proximity of your key fob.

This is perfect for hands-free operation when carrying bags of groceries in harsh weather or during emergencies.

Enhanced Security

Remote keyless systems incorporate premium security measures like advanced encryption rather than relying on physical keys. This reduces many security risks like key duplication.

In addition, some systems have an auto-lock feature after a certain time, which is handy when you constantly forget to lock doors.

Improved Accessibility

Remote keyless systems permit the locking and unlocking of your car remotely with just your key fob. This remote access provided greater accessibility, especially for individuals with disabilities or mobility issues.

Smart Features

Remote keyless systems enable integration with smartphones and home automation.

This smart-key system activates remote starting, GPS tracking and alert systems, enhancing the control, convenience and security of your car.

Potential Drawbacks & Considerations

Risk of Signal Interception

Relay attacks are when a thief captures the signal from your key fob and relays it to another device. It tricks the system into thinking the key fob is close, unlocking your car’s door without your knowledge.

Battery Dependency

The key fob relies on batteries to communicate with the electronic system of your car. So, when it dies, the connection dies as well, leaving you with no access to your vehicle.

Higher Costs

Remote keyless systems are more expensive than traditional keys. From installation and repair and component replacement to maintenance, the costs can be steep.
