Why Add Remote Start to Your 2018 Acura ILX?

Remote start systems enable you to start your vehicle’s engine and climate control system from a distance using a key fob or smartphone app. This feature offers several advantages:

  • Climate Control Comfort: Start the engine and climate control before you enter the vehicle, so it’s comfortably warm in winter or cool in summer.
  • Convenience: Avoid waiting inside or outside the car to heat up or cool down. This is especially useful in bad weather conditions.
  • Security Features: Many remote start systems include anti-theft protection such as engine immobilizers or alerts if the car is tampered with.
  • Preserving Vehicle Health: Warming up your engine remotely on cold days can reduce wear and tear from cold starts, potentially prolonging engine life.

Because the 2018 Acura ILX does not come with factory remote start on all trims, installing an aftermarket system is a popular choice among owners looking to boost their vehicle’s functionality.

Understanding Remote Start Systems

Before purchasing a remote start system, it’s important to understand the basic types available on the market and which will fit your needs and your vehicle.

Types of Remote Start Systems

  • Standard Remote Start: Uses a dedicated key fob to start the vehicle remotely. Typically has a range of a few hundred feet.
  • Two-Way Remote Start: Includes a key fob that can receive confirmation signals from the vehicle, such as whether the engine started successfully or if the doors are locked.
  • Smartphone-Enabled Remote Start: Uses a mobile app to start your vehicle, offering virtually unlimited range as long as both your phone and vehicle have cellular coverage.

Key Features to Look For

  • Compatibility: Ensure the system supports the 2018 Acura ILX’s electrical and security systems.
  • Safety Features: Look for systems with automatic shutoff and safety sensors to prevent starting the car if it’s in gear or the hood is open.
  • Integration: Consider systems that integrate with your existing key fob or smartphone for seamless operation.
  • Professional vs. DIY Installation: Some systems require professional installation to ensure proper wiring and avoid voiding your warranty.

Compatibility and Considerations for the 2018 Acura ILX

The 2018 Acura ILX uses a push-button start system paired with a keyless entry fob, and it has factory security features such as an immobilizer. When adding a remote start system, compatibility with these features is critical to ensure proper function and avoid security issues.

  • Keyless Entry Integration: The remote start system must be able to interface with the push-button ignition and keyless entry system.
  • Immobilizer Bypass: Because the engine immobilizer prevents the engine from starting without the key fob present, the remote start system requires a bypass module to simulate the presence of the key.
  • Transmission Safety: The system must include safety features to prevent the vehicle from starting remotely if it is in gear. The 2018 ILX is an automatic transmission, so integrating with the neutral safety switch is necessary.
  • Climate Control Activation: Some advanced remote start systems can activate the climate control system automatically, which is a desirable feature for comfort.

Tools and Materials Needed for Installation

Before beginning the installation process, gather the following tools and materials:

  • Remote start kit compatible with 2018 Acura ILX
  • Immobilizer bypass module (often included in kit)
  • Wire strippers and cutters
  • Electrical tape and heat shrink tubing
  • Soldering iron or crimp connectors
  • Multimeter or test light
  • Screwdrivers (Phillips and flat-head)
  • Trim removal tools
  • Vehicle wiring diagram for 2018 Acura ILX (available online or in service manuals)
  • Zip ties
  • Safety glasses and gloves

Installing a remote start system on your 2018 Acura ILX involves working with your vehicle’s electrical system. If you are not confident with automotive wiring, it is highly recommended to seek professional help or have the system installed at a certified shop. However, if you plan to do it yourself, follow these detailed steps carefully.

Step 1: Prepare Your Vehicle

  • Park your vehicle on a flat surface and engage the parking brake.
  • Disconnect the negative terminal of the battery to prevent any electrical shorts or accidental airbag deployment.
  • Remove the necessary interior panels to access the ignition switch wiring harness and the steering column area. Use trim removal tools to avoid damaging panels.

Step 2: Identify Wiring Harness Connections

Using the wiring diagram for the 2018 Acura ILX, locate the key wires you will need to tap into, including:

  • Ignition wires (ACC, ON, START)
  • Battery (12V constant power)
  • Ground wire
  • Parking brake wire

  • Connect the ground wire to a clean, unpainted metal surface on the vehicle chassis.
  • Connect the parking brake and brake pedal wires to prevent remote start while the brake is engaged.
  • Connect door trigger and hood pin wires to ensure the system disables remote start if the doors or hood are open.
  • Connect the neutral safety switch wire to prevent starting if the car is in gear.

Step 5: Test the System

  • Reconnect the vehicle battery’s negative terminal.
  • Use the remote start key fob to test the system. Verify that the engine starts remotely and that the vehicle’s lights flash or horn chirps as confirmation.
  • Check that the system automatically shuts off if you open the hood or doors during remote start.
  • Ensure that remote start is disabled when the car is in gear or the brake is pressed.
  • Test the factory key fob and push-button start to confirm they still function normally.

Step 6: Secure and Reassemble

  • Once testing is complete and the system functions correctly, secure all wiring with zip ties and cover exposed wires with heat shrink tubing or electrical tape.
  • Reinstall all interior panels removed during installation.
  • Double-check that no wires are pinched or interfere with vehicle controls.

Additional Tips for a Successful Installation
