1. Introduction
The Directed Electronics 556UW is a universal remote start interface module designed to bypass factory transponder or Radio Frequency (RF) based immobilizer systems in vehicles. This module enables the use of an aftermarket remote start system while preserving the integrity and functionality of the vehicle's original anti-theft system. It is compatible with a wide range of vehicles equipped with transponder keys.
Important Note: A working ignition key is required for the operation of this interface module.
2. Safety Information
- Professional Installation Required: This product requires professional installation. Attempting self-installation without proper knowledge and tools can lead to vehicle damage or improper function.
- Vehicle Compatibility: Ensure the module is compatible with your specific vehicle make and model. Consult a professional installer for verification.
- Electrical Safety: Always disconnect the vehicle's battery before performing any electrical work. Use appropriate wiring and connectors to prevent short circuits and electrical fires.
- Proposition 65 Warning: This product may contain chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Wash hands after handling.
3. Package Contents
The package includes:
- One (1) Directed Electronics Universal Remote Start Interface (Model 556UW)

4. Features
- Universal Compatibility: Works with most transponder-type factory immobilizer systems and any aftermarket remote start system.
- Immobilizer Bypass: Bypasses the factory anti-theft system only when the remote start is active, maintaining factory security when not in use.
- Key-in-the-Box Design: Requires a spare, programmed vehicle key to be placed inside the unit for operation.
- Selectable Key Windings: Features simple jumper selection to tune the kit for specific transponder frequencies. Options include 18 windings for domestic vehicles and 60 windings for European vehicles.
- Tamper Prevention Circuit: Provides the ability to open the keysense circuit, preventing the immobilizer module from reading two RFID signals simultaneously and entering tamper mode.
- Keysense Trigger: Allows the universal transponder bypass to shut off as soon as the driver's ignition key is inserted, preventing the vehicle from detecting a second RFID and causing a tamper code.
- Simple Two-Wire Connection: Designed for straightforward installation.
- Durable Construction: Made with metal and plastic components for longevity.
- Compact Design: Easy to mount in various vehicle locations.
- No Programming Required: Simplifies the setup process.
5. Setup and Installation
WARNING: PROFESSIONAL INSTALLATION IS MANDATORY FOR THIS PRODUCT. IMPROPER INSTALLATION CAN LEAD TO VEHICLE DAMAGE, SYSTEM MALFUNCTION, OR SECURITY VULNERABILITIES.
5.1 Key Requirement
The 556UW module operates using a spare, programmed transponder key from your vehicle. This key must be securely placed within the module. It is recommended to use a key that has had its metal blade removed, leaving only the transponder head, for security and fitment.
5.2 Key Winding Selection
The module features jumpers to select the appropriate key winding setting for your vehicle's transponder frequency:
- 18 Windings: Typically used for domestic vehicles.
- 60 Windings: Typically used for European vehicles.
Consult your vehicle's specifications or a professional installer to determine the correct setting.
5.3 Wiring Connections
The 556UW module typically requires the following connections to your vehicle's electrical system and aftermarket remote start unit:
- Red Wire: Connect to a constant 12V positive power source.
- Black Wire: Connect to a chassis ground.
- Blue Wire: Connect to the status output (or remote start activation output) from your aftermarket remote start unit. This signal activates the bypass module.
- Pink Wire (Optional): Ignition Output. May be used in specific vehicle applications.
- Violet Wire (Optional): Positive Keysense Input. Used for the keysense trigger function.
- Green Wire (Optional): Negative Keysense Input. Used for the keysense trigger function.
Refer to the detailed wiring diagram provided with your specific remote start system and the 556UW module for precise connections. Vehicle-specific wiring information may also be required.
5.4 Antenna Ring Placement
The module includes a loop wire that acts as an antenna. This loop must be carefully routed around the vehicle's ignition cylinder, specifically around the transponder ring. Proper placement ensures the module can effectively read the transponder key placed inside it. Ensure the loop is secured and does not interfere with the ignition key insertion or turning.
5.5 Mounting
Mount the 556UW module in a secure, hidden location within the vehicle, away from excessive heat, moisture, and moving parts. Ensure the module is easily accessible for future servicing if needed, but not easily discoverable by unauthorized individuals.
6. Operation
The Directed Electronics 556UW module operates automatically in conjunction with your aftermarket remote start system:
- When the remote start system is activated, the 556UW module receives a signal (via the Blue wire).
- Upon activation, the module energizes, allowing it to read the transponder key placed inside it.
- The module then transmits the valid transponder code to the vehicle's immobilizer system, temporarily bypassing it and allowing the engine to start remotely.
- Once the remote start cycle ends, or if the driver inserts their key into the ignition (triggering the keysense input), the 556UW module deactivates.
- When the module is deactivated, the vehicle's factory immobilizer system returns to full functionality, ensuring the original anti-theft protection is maintained.
7. Maintenance
The Directed Electronics 556UW module is designed for maintenance-free operation. To ensure continued reliability:
- Ensure all wiring connections remain secure and free from corrosion.
- Avoid exposing the module to extreme temperatures, moisture, or physical impact.
- Do not attempt to open or modify the module, as this will void the warranty and may cause damage.
8. Troubleshooting
If you experience issues with your 556UW module or remote start system, consider the following:
- Vehicle Fails to Remote Start:
- Verify that the spare transponder key is correctly placed and secured within the 556UW module.
- Check all wiring connections for looseness or corrosion, especially the power, ground, and remote start activation wires.
- Ensure the antenna loop around the ignition cylinder is properly positioned and not damaged.
- Confirm the key winding selection (18 or 60) matches your vehicle's requirements.
- Ensure your aftermarket remote start system is functioning correctly and sending the activation signal to the 556UW.
- Vehicle Enters Tamper Mode or Immobilizer Light Flashes:
- This can occur if the vehicle detects two RFID signals simultaneously. Ensure the keysense trigger is correctly wired and functioning to deactivate the 556UW when the driver's key is inserted.
- Verify the tamper prevention circuit is correctly configured.
- Interference with 2-Way Remote Communication:
- In some rare instances, the operation of the bypass module may cause minor interference with the signal reception of certain 2-way remote start systems, particularly when the vehicle is running. If this occurs, consult your professional installer for potential solutions or alternative module configurations.
For persistent issues, it is recommended to contact your professional installer or Directed Electronics technical support.
