3. Setup and Installation
Warning: Installation of this product requires knowledge of automotive electrical systems. Incorrect installation can lead to vehicle damage or fire. If you are not confident in your abilities, please seek professional installation.
3.1. Wiring Connection Diagram
Refer to the following diagram for proper wiring connections. Identify your vehicle's central locking system type (electric or pneumatic) and connect accordingly. Ensure all connections are secure and insulated.
Figure 3.1: Detailed wiring connection diagram for the Shkalacar central locking system. This diagram illustrates connections for power, ground, central lock control wires, and direction lights. It also shows the learning button and jumpers for electric (J1) or pneumatic (J2) lock programming.
3.2. General Wiring Guidelines
- Power (Red Wire): Connect to a constant +12V power source. Ensure this connection is fused.
- Ground (Black Wire): Connect to a reliable chassis ground point.
- Central Lock Control Wires (Orange, White, Yellow, Orange/Black, White/Black, Yellow/Black): These wires connect to your vehicle's central locking system. The specific configuration depends on your vehicle's locking mechanism (e.g., positive trigger, negative trigger, 5-wire alternating polarity). Consult your vehicle's wiring diagram or a professional for correct identification.
- Direction Lights (Brown Wires): Connect these to your vehicle's turn signal wires to provide visual confirmation of lock/unlock operations.
- Antenna: Position the antenna wire away from metal objects for optimal range.
3.3. Remote Control Programming (Learning Button)
The main control unit features a 'Learning Button' (as indicated in Figure 3.1). This button is used to program or re-program the remote controls to the unit. Specific programming steps may vary, but typically involve pressing the learning button on the control unit, then pressing a button on the remote control within a short timeframe to pair them.
4. Operating Instructions
Once installed, the system provides simple remote control over your vehicle's central locking.
4.1. Locking the Vehicle
Press the Lock button on the remote control. The vehicle's doors will lock, and the direction lights will flash once (if connected).

4.2. Unlocking the Vehicle
Press the Unlock button on the remote control. The vehicle's doors will unlock, and the direction lights will flash twice (if connected).
4.3. Car Finding Feature
To locate your vehicle in a large parking area, press and hold the Lock button (or a dedicated car finding button if present on your remote). The vehicle's direction lights will flash, and the horn may sound (if connected) to help you pinpoint its location.

5. Maintenance
5.1. Remote Control Battery Replacement
The remote controls require 2 Lithium Ion batteries. When the remote's range decreases significantly or it stops responding, it is likely time to replace the batteries. Refer to the remote control's casing for instructions on how to open it and replace the batteries.
5.2. General Care
- Keep the main control unit and remote controls dry and away from extreme temperatures.
- Avoid dropping the remote controls.
- Periodically check wiring connections for security, especially after initial installation.
6. Troubleshooting
If you encounter issues with your central locking system, refer to the following common problems and solutions:
- System not responding to remote:
- Check remote control batteries and replace if necessary.
- Ensure the remote control is within range of the vehicle.
- Re-program the remote control to the main unit using the learning button.
- Check the main unit's power and ground connections.
- Doors do not lock/unlock:
- Verify all central lock control wires are correctly connected to the vehicle's locking system.
- Ensure the vehicle's central locking system is functional manually.
- Check for blown fuses in the wiring harness or vehicle's fuse box.
- For vehicles requiring a double pulse to unlock, this system may not be directly compatible without additional relays.
- Short circuit or blown fuse:
- Immediately disconnect power.
- Thoroughly inspect all wiring for exposed wires, incorrect connections, or wires touching metal.
- Ensure the correct fuse rating is used.
If problems persist after troubleshooting, it is recommended to consult a professional automotive electrician.
