Ready to ShipPassive keyless entry systems, also known as PKE systems, are electronic access and authorization control systems that automatically detect the presence of an authorized key. This allows the holder to perform actions like entering a building or starting a vehicle without having to press any buttons on the key. The system comprises two main components: an antenna module that communicates with the key and a control unit that processes the signals.
There are several types of passive keyless entry systems, each designed to enhance security and convenience in different environments.
Vehicle PKE systems:
Vehicle PKE systems allow drivers to unlock and start their cars while keeping the key fob in their pockets or bags. These systems use low-frequency signals for short-range communication, ensuring security by requiring close proximity to the vehicle for unlocking functions. By pressing a button on the key fob, the user can send a signal to the car, enabling them to perform specific actions like locking or unlocking the doors. This design feature combines convenience with security, making it difficult for unauthorized individuals to access the vehicle.
Building Access PKE systems:
Building access PKE systems are employed in commercial and residential buildings to control entry points like doors and gates. These systems often use higher frequency signals than vehicle systems, enabling communication over longer distances. Additionally, they may incorporate multi-factor authentication methods, such as combining key fobs with PIN codes or biometric data, to enhance security further. This is especially useful in sensitive areas like data centers or research labs, where access must be restricted to authorized personnel only.
Mobile PKE systems:
Mobile PKE systems use smartphones as the authorized key. Users can unlock and start their vehicles or gain access to buildings by using secure communication channels and encryption in mobile PKE systems. This eliminates the need for a separate physical key fob, streamlining access control for users. Mobile PKE systems can also integrate with other mobile applications, providing additional functionalities such as remote vehicle monitoring or building access management.
Multi-credential PKE systems:
Multi-credential PKE systems accept various authorized keys, such as key fobs, cards, or mobile devices, providing flexibility and convenience to users. This is particularly advantageous in environments where multiple access methods are desired or where different user groups require tailored access solutions. For instance, employees can use access cards, visitors can receive temporary key fobs, and authorized personnel can utilize mobile devices for access in corporate settings.
Vehicle Coverage
Different PKE systems have different scopes of coverage depending on the brand and model of the vehicle. For example, luxury vehicles have a more extensive PKE system that allows access to all four doors and the trunk, while some standard vehicles may only have it available on the driver's door. Understanding the exact vehicle coverage of the PKE system is crucial for installing and maintaining it correctly.
Key Fob Battery
Key fob batteries are usually lithium coin batteries, such as CR2032 or CR2025. These batteries are designed to power the key fob's low-energy functions for an extended period, usually lasting one to three years, depending on usage. Regular replacement of the key fob battery is essential for maintaining the PKE system's performance, as a low battery can lead to reduced range or intermittent operation.
Relay Attack Protection
Some advanced PKE systems incorporate relay attack protection measures. These measures include additional encryption of the signal between the key fob and the vehicle, making it significantly more challenging for thieves to amplify and relay the signal using specialized equipment. If this protection is available, it should be considered a valuable addition to the vehicle's security, especially for high-risk areas.
Integration with Security Systems
Integration with other security systems such as alarms, immobilizers, or GPS tracking systems can enhance overall vehicle security. For instance, if an unauthorized entry attempt is detected, the PKE system can communicate with the alarm system to trigger it, or it can inform the immobilizer to prevent the engine from starting. This integrated approach provides a comprehensive and coordinated response to security threats, making it much more difficult for thieves to succeed.
Regular Key Fob Battery Replacement
Users should check the key fob battery regularly and replace it promptly when the battery level drops. The replacement process is generally simple and can be done by following the manufacturer's instructions or seeking professional assistance.
Key Fob Signal Interference
Some electronic devices such as mobile phones, RFID readers, or certain types of LED lights may interfere with the normal signal transmission of the key fob. If users notice a significant reduction in the operating range of the key fob, they can try moving away from these devices to determine whether it is an interference issue.
Periodic System Checks
Users can have a qualified technician periodically check and maintain the PKE system to ensure that all components are functioning correctly. During the inspection, the key fob, receiver, and other related parts will be checked for damage, wear, or moisture infiltration, and necessary repairs or replacements will be made in a timely manner.
In addition to the above, users can take some simple preventive measures to extend the service life of the PKE system. For example, keeping the key fob away from moisture, dust, and high temperatures, and protecting it from physical impact or collision.
Before buying a PKE system for resale, it is important to understand the market and know what customers want. Here are some factors to consider when choosing a PKE system to trade.
First, understand that there are two types of PKE systems. One is suitable for low-security needs, while the other is high-security level PKE. The high-security level PKE system offers more security and is ideal for luxury and high-value vehicles. It is better to choose a high-security PKE entry system because it serves a specific purpose and is mostly preferred by car owners. This will also reduce the chances of theft and car break-ins.
Consider the design and make of the PKE entry system. People have different preferences when it comes to styles and designs. It is advisable to choose a variety of styles, shapes, and designs so that customers can have a range of products to choose from.
