3. Installation
Installation of this system is a plug-and-play process, requiring no soldering of the factory key's PCB. However, professional installation by a trained alarm installer or locksmith is highly recommended to ensure correct setup and functionality. One working factory key fob is required to be placed inside the control module during installation.
3.1. Antenna Placement
Proper placement of the PKE antennas is crucial for optimal performance of the passive keyless entry function. Refer to the video below for guidance on antenna installation.
Video 3.1: This video demonstrates the correct installation procedure for the PKE antennas within the vehicle, showing placement of the front and rear antennas, and the HF antenna.
3.2. Control Module and Key Fob Integration
The control module should be placed securely, typically under the ignition cylinder or driver's seat. A working factory key's PCB is inserted into the control module to enable the system's functions.

4.1. Passive Keyless Entry (PKE) Function
The PKE function automatically locks or unlocks the vehicle as you approach or walk away from it, typically within a range of 2-3 meters. This feature can be enabled or disabled as per user preference.

5. Programming
After completing the wiring connections, a new programming sequence is required for the system to function correctly. Please refer to the specific programming method outlined in the detailed installation guide provided with your product for step-by-step instructions.
6. Maintenance
To ensure optimal performance and longevity of your EASYGUARD PKE system, keep the key fobs dry and avoid exposing them to extreme temperatures. Replace the CR2 batteries in the key fobs as needed. Regular checks of wiring connections are recommended during routine vehicle maintenance.
7. Troubleshooting
If you experience issues with the system, consider the following:
- System not responding: Check key fob battery levels. Ensure the factory key's PCB is correctly seated in the control module.
- PKE not working: Verify antenna connections and placement. Ensure the PKE function is enabled (refer to Section 4.2).
- Vehicle not starting: The system includes a high-security feature that prevents the car from starting if the key is not detected inside the vehicle. Ensure the key fob is present and functioning.
- Remote range issues: Obstructions or electromagnetic interference can affect range. Ensure clear line of sight where possible.
For persistent issues, contact customer support or a professional installer.
