Core Features & Benefits
1. Passive Keyless Entry (PKE)
The system utilizes RFID or similar low-frequency polling technology. When the driver carrying the smart key fob approaches the vehicle (typically within 2-3 meters), the car automatically detects the key and unlocks the doors without any button press. Conversely, when the key fob moves away beyond the set range, the system automatically locks the doors and activates the alarm.
2. Remote Engine Start
This feature allows the user to start the car's engine from a distance using the remote control. This is particularly useful for pre-heating the car in winter or cooling it down in summer before entering. Some advanced models also include a timer or smartphone app control function.
3. Central Door Locking & Anti-Theft Alarm
The system can simultaneously control all doors and the trunk lock. Once armed, the alarm will trigger a loud siren and flashing lights if it detects unauthorized entry, impacts (via shock sensor), or attempts to break the ignition circuit.
4. Additional Convenience Functions
Auto Window Roll-Up: Upon locking the car or after the engine is turned off and the driver leaves, the system can automatically close any open windows.
Car Finder: Pressing a specific button on the remote causes the car to honk and flash its lights, making it easy to locate in a crowded parking lot.
Trunk Release: Remote-controlled trunk pop function for added convenience.
Installation & Usage Guide
Installation Steps (Professional Recommended):
Disconnect Battery: Always disconnect the negative terminal of the car battery before starting any installation to prevent short circuits.
Locate Central Lock Module: Find the vehicle's existing central locking control unit or the wiring harnesses leading to each door lock actuator.
Connect Wires: Connect the wires from the new keyless entry module to the corresponding wires in the car (lock, unlock, power, ground, ignition, etc.). A detailed wiring diagram specific to your car model is essential.
Mount Components: Securely mount the main control unit, shock sensor, and antenna in concealed but effective locations within the vehicle.
Reconnect Battery & Test: Reconnect the battery and thoroughly test all functions (lock, unlock, remote start, alarm) before reassembling all panels.
Note: Due to the complexity of modern vehicle electrical systems, professional installation by a certified auto electrician is highly recommended to avoid damaging the car's ECU or other sensitive electronics.
Daily Usage:
Unlocking: Walk towards the car or press the unlock button on the remote.
Locking: Walk away from the car or press the lock button. You should hear a confirmation beep or see the lights flash.
Remote Start: Typically involves pressing the lock button followed by the remote start button (often a circular arrow icon).
