Note: For some older cars, if the car connector is different from the EASYGUARD smart key connector, you may need to unplug the car 9B connector and replace it with the blue connector, or unplug the car 7B connector and replace it with the white connector by the car connector.
Factory Key Integration
One working factory key must be placed inside the control module. Follow these steps:
- Unscrew the control module.
- Carefully take out the circuit board.
- Place the car OEM key fob's PCB into the designated slot.
- Screw the board back into place.

IMPORTANT: After finishing key soldering (if applicable to your model) and placing the PCB, you must put back the cover before you can start the car, or the car may be unable to start.
Antenna Installation
Proper placement of the antennas is crucial for optimal performance. Refer to the diagram for recommended installation positions:
Figure 6: Antenna Installation Positions
- P1 & P2: High frequency antenna installation positions. Choose either P1 or P2.
- P3 & P4: PKE antenna installation positions.
Car Key Detection Antenna: This antenna should be placed in a position that allows for proper key detection. If not installed well, you may need to touch the handle to lock/unlock the car even if the key fob is inside the car.

DIP Switch Setting
The DIP switch setting depends on your car key's PCB style (1050 or 1005). You can find this information on your OEM key fob's PCB.
- If your car key is 1050 style, press the DIP switch to the left (1050 side).
- If your car key is 1005 style, press the DIP switch to the right (1005 side).

Remote Control Programming
- Keep pressing and holding the white programming button (refer to Figure 4 for location). Do not release it.
- Quickly press the "Lock" button once on the remote you plan to program. The indicator light will flash when you press it, signifying successful programming.
- Release the programming button after you have programmed all desired remotes. A maximum of 3 key fobs can be programmed.
- If programming is unsuccessful, check if the remote control has batteries. Also, try unplugging and re-plugging the power connector to the main module and attempt programming again.
After the remote control is programmed, when you press a button on the remote, the LED indicator near the programming button will blink. If the PKE antenna is plugged in and the remote control is nearby, the indicator light will be on for a long time, indicating the vehicle can be started. If the key is moved more than 5 meters away, the light will turn off, and the vehicle cannot be started.

Maintenance
Remote Control Battery
The remote control uses a CR2032 battery. If the remote control is not functioning correctly or the indicator light does not flash during programming, check the battery and replace it if necessary.
System Reset
If you encounter issues with programming or system functionality, try unplugging and re-plugging the power connector to reset the system before attempting programming again.
Troubleshooting
- Car unable to start: The system features high security. The car will not start if the key is not detected inside the car. Ensure the factory key is correctly placed within the control module and the key detection antenna is properly installed.
- Remote control programming failure: If programming fails, verify that the remote control has a working CR2032 battery. Also, try unplugging and re-plugging the power connector to the system and attempt programming again.
- Need to touch door handle to lock/unlock despite key fob being inside: This indicates an issue with the car key detection antenna installation. Ensure the antenna is placed correctly as shown in Figure 7.
- Remote working range issues: The remote control has a working range of approximately 20-30 meters. If you experience significantly reduced range, check for obstructions or interference, and ensure the antennas are correctly installed.

User Tips
- Always ensure the factory key's PCB is securely placed inside the control module and the module cover is properly re-attached after installation or maintenance.
- If you experience inconsistent PKE functionality, double-check the placement of the car key detection antenna. Improper placement can lead to the need for manual door handle interaction.
- Keep spare CR2032 batteries on hand for your remote controls to avoid unexpected power loss.
- Before purchasing, confirm your BMW G series car has the comfort access function. If not, consider the ESW309C or ESW309C-N series.
