What is a Remote Start System?

A remote start system is a device that allows you to start your vehicle from a distance. Remote start systems typically use a key fob or smartphone app to send a signal to the vehicle’s computer, which then starts the engine.

Remote start systems are convenient for a number of reasons. They can be used to warm up your vehicle on a cold morning or cool it down on a hot day. They can also be used to start your vehicle if you’re running late for work or an appointment.

Types of Remote Start Systems

There are two main types of remote start systems:

• Keyless entry systems use a key fob to send a signal to the vehicle’s computer.
• Smartphone apps use your smartphone to send a signal to the vehicle’s computer.

Keyless entry systems are typically more affordable than smartphone apps, but they offer fewer features. Smartphone apps are more expensive, but they offer a wider range of features, such as the ability to start your vehicle remotely, lock and unlock the doors, and check the fuel level.

Features to Look for in a Remote Start System

When you’re shopping for a remote start system, there are a few features you should look for:

• Range: The range of a remote start system is the distance from which you can start your vehicle. Most remote start systems have a range of about 500 feet, but some systems have a range of up to 1,000 feet.
• Programmability: The programmability of a remote start system refers to the ability to set the start time and duration. Some systems allow you to set the start time for a specific day and time, while others allow you to set the start time for a specific period of time.
• Security: Some remote start systems include security features, such as a PIN code or a rolling code. These features help to protect your vehicle from theft.

How to Install a Remote Start System

Installing a remote start system yourself is relatively easy, but it can be time-consuming. If you’re not comfortable working on cars, you may want to have a professional install the system for you.

To install a remote start system, you’ll need the following tools:

• A screwdriver
• A wrench
• A soldering iron
• A wire crimper

You’ll also need the following parts:

• A remote start kit
• A wiring harness
