Now that we’ve discussed the best anti-theft device, we are going to talk about how you can craft your own best DIY remote car starter at very reasonable prices. These are instructions for creating the best remote car starters at home.

How to Make the Best DIY Remote Car Starter

There are three types of remote car starters that can be designed at home and we’ll be discussing them.

  • Bluetooth car starter
  • Wi-fi car starter
  • Phone application car starter

Bluetooth Car Starter

Creating a Bluetooth car starter requires a lot of instructions. The main function of a Bluetooth car starter is to link up with the car using Bluetooth and then be able to start the car engine.

The following are some instructions required to be followed while creating a DIY Bluetooth car starter.

Items Required

The requirements for creating an excellent DIY Bluetooth car starter at home are as follows:

  • Bluetooth module
  • Arduino system
  • Connecting wires
  • Batteries
  • System Data
  • Hardware Data
  • Arduino code
Data Collection

In this step, all the hardware and the software requirements and features of the car are noted so that accurate electrical requirements can be fulfilled and the Bluetooth connection can be made possible.

Writing Code

This is one of the most important and difficult steps perhaps in the whole process of creating this device. The reason being that in this code you have to write different interaction codes, which send signals to the car to perform the required task once the wiring is complete.

System Connection

After the hard part of collecting the data and writing the code is done, you need to use connecting wires to create the right wiring in your car, so it could be affected by the Bluetooth signal sent out by the Bluetooth device.

And once all of these steps are taken care of, your DIY remote car starter is ready to work and function.

Wi-Fi Car Starter

The signals from the Bluetooth device can only go just enough distance, however, when replace by wi-fi technology, the range of the signals increases by a long shot, and cars parked further away can be accessed. The following are some instructions that need to be followed in order to create the best DIY remote car starter that uses a wi-fi connection.

Items Required
  • Connecting wires
  • Wire cutters
  • Heat gun
  • Resistor
  • Diode
  • Spark core

Well, once you have all these items and more, the wires need to be connected to the car starter device using the heat gun, and the phone that you have should have the device accessing app which will use wi-fi to control the vehicle’s engine.


After all the wires are connected and the changes are made, everything needs to be properly adjusted to seem natural and the wi-fi car starter is finalized.

Phone Application Car starter

Car starters can be fully functionally developed using mobile applications as well without any other proper devices nowadays. The following are the requirements and instructions to be followed while creating a phone application car starter.

Items Required
  • Bluetooth module
  • Connecting wires
  • Resistor
  • Heat gun
  • Application
Downloading application

First off, what you need to do is download an editable application that allows various buttons to function differently which could be edited as well as the user pleases. Different buttons can be functioned and programmed for different vehicular activities.


The Bluetooth module and all other materials must be connected and attached to the wiring of the car so that the buttons pressed in the phone application can be used to control the car engine.


After all the necessary connections and coding, the final product will be a remote car starter application on your phone which would be excellently used for the remote access of your car.


Following all these instructions, you can create the perfect, affordable, and fully functioning best DIY remote car starter at home depending upon which type of access you might require. Once you choose the type and create your own remote car starter, life becomes much more efficient and easier. So after following the instructions, and making additional changes not only can you control your car engine, but also program other functions which may include creating an automatic garage door and various other things to provide technological ease to your life. Choose a method that suits your requirements and you find it easy to follow without any external help. All the best!
