How Much To Install Auto Start

So, you're thinking about installing a remote start system in your ride? Excellent choice! It's a fantastic upgrade for comfort, especially during those blistering summer or freezing winter months. But before you jump in, it's crucial to understand what goes into the installation process and, of course, the cost. While I can't give you an exact dollar figure (prices vary wildly based on car model, system complexity, and your region), I can give you the technical knowledge to make an informed decision and potentially save some money by doing some of the work yourself.

Understanding the Cost Factors

The cost of installing an auto-start system breaks down into two main components: the hardware (the remote start system itself) and the labor. Let's dissect each of these.

Hardware Costs

Remote start systems range in price from a couple hundred dollars to well over a thousand, depending on features and brand. Here's what influences the price:

Range: Basic systems have a limited range (often a few hundred feet), while premium systems boast ranges of a mile or more using two-way communication. Two-way systems confirm the start command was received and the engine is running.
Features: More features mean more money. Think alarm integration, keyless entry, trunk release, heated seat activation, and smartphone control.
Vehicle Compatibility: Some vehicles require more complex integration modules, especially those with sophisticated security systems or push-button starts. These modules can significantly increase the overall cost. A bypass module, for example, is often needed to temporarily disable the vehicle's immobilizer during remote start.
Brand Reputation: Reputable brands like Compustar, Viper, and Python often command a higher price due to their quality, reliability, and support.

Labor Costs

Labor costs depend heavily on the complexity of your vehicle's electrical system and the installer's hourly rate. Some installs are straightforward, while others require extensive wiring and programming. Here's a breakdown:

Complexity of Installation: Older vehicles with simpler electrical systems are generally easier and cheaper to install a remote start in. Newer vehicles with CAN-BUS systems and advanced security features require more time and expertise.
Installer's Hourly Rate: Rates vary depending on your location and the installer's experience. Expect to pay anywhere from $75 to $150 per hour.
Bypass Module Programming: As mentioned before, bypass modules are often needed. Programming these modules can add to the labor time.
Additional Features: Integrating extra features like alarm systems or heated seats increases labor time.

Key Specs and Main Parts of a Remote Start System

A typical remote start system consists of the following key components:

Remote Transmitter (Fob): This is what you use to send the start command to the vehicle.
Control Module: The "brain" of the system. It receives the signal from the remote, interprets it, and activates the necessary circuits to start the engine.
Wiring Harness: A bundle of wires that connects the control module to the vehicle's electrical system.
Bypass Module (Immobilizer Bypass): This module is essential for most modern vehicles with security systems. It temporarily disables the immobilizer, allowing the remote starter to crank the engine.
Hood Pin Switch: A safety feature that prevents the remote start from activating if the hood is open. This is crucial to prevent accidents during maintenance.
Antenna: Used to receive signals from the remote transmitter.

Basic Remote Start Wiring Diagram (Simplified)

While I can't provide a specific wiring diagram for every vehicle model, I can outline a simplified, generic diagram to illustrate the core connections. Keep in mind that this is a greatly simplified representation and should not be used for actual installation without a vehicle-specific diagram from the remote start manufacturer.

Disclaimer: Working with automotive electrical systems can be dangerous. Always disconnect the negative battery terminal before working on any wiring. If you are not comfortable working with electrical systems, seek professional assistance.

Here's a conceptual overview:

Power Connection: The remote start module needs a constant 12V power supply from the battery, usually via a fused connection.
Ground Connection: A solid ground connection is essential for proper operation.
Ignition Wire Connection: This wire is connected to the vehicle's ignition wire, which is activated when you turn the key to the "ignition" position.
Starter Wire Connection: This wire is connected to the starter wire, which activates the starter motor.
Accessory Wire Connection: This wire is connected to the accessory wire, which powers accessories like the radio and climate control system.
Tachometer Wire Connection (or Data Interface): Some systems require a tachometer signal to verify the engine is running. Newer systems often use a data interface (CAN-BUS) to communicate with the vehicle's computer.
Brake Switch Wire Connection: This wire is connected to the brake switch, which disables the remote start when the brake pedal is pressed.
Hood Pin Switch Connection: This wire connects to the hood pin switch, which prevents remote starting when the hood is open.

A vehicle-specific wiring diagram, typically provided by the remote start manufacturer, will detail the exact wire colors, locations, and any necessary resistors or diodes. Always consult this document.

How It Works

Here’s the general sequence of events when you activate the remote start:

You press the start button on the remote transmitter.
The transmitter sends a radio frequency (RF) signal to the control module in the vehicle.
The control module verifies the signal and checks safety conditions (e.g., hood is closed, brake pedal is not pressed).
The bypass module temporarily disables the immobilizer.
The control module activates the ignition, starter, and accessory circuits, mimicking the action of turning the key.
The engine starts.
The control module monitors the tachometer signal (or data interface) to ensure the engine is running.
The vehicle runs for a preset time (usually 15-20 minutes) or until you turn it off with the remote.

Real-World Use – Basic Troubleshooting

Here are a few common issues and potential solutions:

Remote start doesn't work at all:
- Check the battery in the remote.
- Check the fuses for the remote start system.
- Ensure the hood pin switch is properly installed and functioning.
- Verify all wiring connections are secure.
Remote start cranks but doesn't start:
- Verify the tachometer wire (or data interface) is properly connected.
- Check the bypass module programming.
Remote start starts but shuts off immediately:
- Check the tachometer wire (or data interface) connection.
- Check for any error codes in the control module (if applicable).

Safety Considerations

Working with automotive electrical systems can be dangerous. Here are some critical safety precautions:

Disconnect the Negative Battery Terminal: Always disconnect the negative battery terminal before working on any wiring to prevent electrical shorts and potential damage.
Work in a Well-Ventilated Area: Automotive wiring can release fumes when heated, so work in a well-ventilated area.
Use Proper Tools: Use appropriate crimping tools, wire strippers, and multimeters to ensure safe and reliable connections.
Never Cut or Splice Wires Without Understanding Their Function: Cutting or splicing the wrong wire can damage your vehicle's electrical system. Always consult a vehicle-specific wiring diagram.
Be Cautious Around Airbag Wiring: Airbag systems are extremely sensitive. Avoid working near airbag wiring unless you are specifically trained to do so. Accidental activation of an airbag can cause serious injury.

Final Thoughts

Installing a remote start system can be a rewarding DIY project, but it requires careful planning, attention to detail, and a solid understanding of automotive electrical systems. Don't be afraid to seek professional help if you're unsure about any aspect of the installation. A properly installed remote start will provide years of convenience and comfort.
