Radio Code Calculator for JavaScript

#javascript #radiocode #radio #car

Radio Code Calculator is a comprehensive online service that also includes a Web API & SDK for generating car radio unlock codes for a wide range of popular vehicle brands.

It is commonplace for vehicle radio and navigation units to prompt for an unlocking code after a car battery failure or disconnection. This is a standard anti-theft protection measure.

With our Car Radio Code Calculator, you can effortlessly generate radio codes that are 100% valid, enabling you to unlock car radios and navigation systems without the high cost of going through authorized dealers.

Radio Code Calculator

The service is available through a simple online interface and Web API, with multiple SDK development libraries for popular programming languages.

Thanks to our solution, you can create, for instance, mobile or web applications that allow for easy generation of radio codes.

Supported car models and radios

We are dedicated to constantly improving our service and regularly update our algorithms to support new car models and their radios.
Any new algorithms added will be automatically and freely accessible to you under your current license.

For end customers, we offer individual calculators as a paid service. Relevant subpages on our site list the supported radios for each calculator, which you can verify before making a purchase.

Use of radio code calculator

Our radio code generation service can be accessed from anywhere in the world with an internet connection. It is designed for individuals and businesses alike, including mechanics, car dealerships, and other automotive professionals who need to unlock car radios and navigation systems.

If you are an individual or a business, you can make money from our code generation service by offering it as an additional service to your existing customers or by promoting it through your website or social media channels. You can also integrate our service into your software or application using our Web API or SDK to offer it to a wider audience.

Android App developers

The main audience for our software is clearly developers and programmers, either of mobile or desktop applications.

Shopping cart Online stores

If you run an online e-commerce store, you can sell radio codes through it using our software solutions.

Car Auto repair shops

We also encourage car repair shops whose customers often use car radio unlocking services.

Person Private individuals

Private individuals will also profit from our solution by generating codes and selling them on car forums or auction sites such as eBay, Craigslist.

No limits!

You can generate codes without limitation with your purchased one-year license.

Set your own price for generating a single code and start earning by using tried and tested algorithms from a programming language you know.

If you are not a programmer - don't worry. Just use our online calculator.

Installation

The preferred way of WebApi interface installation is via NPM.

Run:

npm i radio-code-calculator
Enter fullscreen mode Exit fullscreen mode

Or add this entry:

  "dependencies": {
    "radio-code-calculator": "latest"
  },
Enter fullscreen mode Exit fullscreen mode

directly to your package.json in dependencies section.

The installation package is available at https://www.npmjs.com/package/radio-code-calculator

Packages for other programming languages

The installation packages have been uploaded to repositories for several popular programming languages and their source codes have been published on GitHub:

Repository Language Installation Package GitHub
Packagist repository for PHP and Composer PHP Add the following line to require section of your composer.json file "pelock/radio-code-calculator": "*" Packagist Sources
PyPI repository for Python Python Run pip install radio-code-calculator PyPi Sources
NPM repository for JavaScript and TypeScript JavaScript, TypeScript Run npm i radio-code-calculator or add the following to dependencies section of your package.json file "dependencies": { "radio-code-calculator": "latest" }, NPM Sources

Usage examples

Radio code generation

This example demonstrates code generation for a selected radio model. All input parameter validation is done on the server side and if the radio serial number has an invalid length or pattern - the service will return an error.

Radio code generation with additional offline validation

Radio codes are generated based on input parameters such as the radio's serial number, among others.

Radio serial numbers are different for different radios, they have different lengths and different patterns, some may consist of just digits e.g. 1234, while others may consist of digits and letters e.g. AB1234XYZ.

Validation of this data is done on the server side. However, to make things more efficient, we can use the information about available limits and patterns of particular serial numbers to, for example, set these limits in controls in our own applications without unnecessary calls to the Web API.
