Wiring Lokar Door Handles with the Legacy 20-Circuit Infinitybox System
The Legacy Infinitybox system makes it simple to integrate Lokar door handles with electric door poppers. Follow these step-by-step instructions:
Installation Steps
1. Install the Hardware
- Mount the Lokar door handles according to manufacturer instructions
- Install door popper solenoids in each door per the included guidelines
2. Connect POWERCELL Outputs
- Select OPEN outputs on your POWERCELL module for each door
- Connect the POWERCELL output wire to one lead on the door popper solenoid
- Ground the other solenoid lead
3. Wire MASTERCELL Inputs
- Connect the MASTERCELL input (corresponding to your OPEN output) to the switch inside the Lokar door handle
- Ground the remaining switch wire
How It Works
When you pull the Lokar door handle, the MASTERCELL input grounds out. This triggers the MASTERCELL to command the POWERCELL to activate the output, pulsing the door popper solenoid and releasing the door latch.

Bonus Security Feature: We can program your system to block door popper switches when security is enabled via inLINK or inTOUCH NET. This ensures doors only open when you disable security using your inLINK key fob or smartphone app.
Wiring Lokar Door Handles with inMOTION NGX System
The Next Generation inMOTION NGX simplifies the installation even further. This door-mounted control module features two H-Bridge relays designed for power locks and power windows.
Simplified NGX Installation
The inMOTION NGX installs directly inside your door, keeping all wiring localized:
- Use one output from the power lock relay pair to control the door popper solenoid
- Wire the Lokar door handle switch directly to the inMOTION NGX in the same door
- Control both the switch input and popper output from a single module
This configuration dramatically reduces wiring complexity compared to traditional systems.

The inMOTION NGX also supports security integration, allowing you to configure door poppers to function only when the vehicle security system is disarmed.
