**[Radio Code Calculator](https://www.pelock.com/products/radio-code-calculator)** is an online service along with [Web API & SDK](https://www.pelock.com/products/radio-code-calculator/sdk) for generating car radio unlock codes for popular vehicle brands.

After a car battery failure or disconnection, many vehicle radio and navigation systems will prompt for an unlock code as a standard anti-theft precaution.

Our Radio Code Calculator enables you to generate **100% valid radio codes** to unlock your car radio and navigation systems, eliminating the need for costly services from authorized dealers.

![Radio Code Calculator](https://www.pelock.com/img/en/products/radio-code-calculator/car-radio-code-calculator-online-web-api-sdk.jpg)

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

Our service is being continuously developed and new algorithms are gradually added for new car models and their radios.

If a new algorithm is added, you will get automatic and free access to it as part of your current license.

Individual calculators are available on our site as a paid service for end customers. You can verify them and see lists of supported radios on the relevant subpages:

## Use of radio code calculator

Where and who can use the radio code generation service and make money from code generation?

### ![Android](https://www.pelock.com/img/en/icons/android-32.png) App developers 
The main audience for our software is clearly developers and programmers, either of mobile or desktop applications.

### ![Shoping cart](https://www.pelock.com/img/en/icons/cart-32.png) Online stores 
If you run an online e-commerce store, you can sell radio codes through it using our software solutions.

### ![Car](https://www.pelock.com/img/en/icons/car-32.png) Auto repair shops
We also encourage car repair shops whose customers often use car radio unlocking services.

### ![Person](https://www.pelock.com/img/en/icons/user-32.png) 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](https://www.pelock.com/products/radio-code-calculator/online).

## Installation

The preferred way of Radio Code Calculator Web API interface installation is via [pip](https://pypi.org/project/pip/).

Run:

```
pip install radio-code-calculator
```

or 

```
python3 -m pip install radio-code-calculator
```

And then add this import to your source code:

```python
from radio_code_calculator import *
```

The installation package is available at https://pypi.org/project/radio-code-calculator/

## 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.

```python
#!/usr/bin/env python

```

## 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`.

```python
#!/usr/bin/env python
