Who this course is for
Mechanics who want to offer more
Keep key, coding and ECU jobs in your own garage instead of sending them out.
People who want to become auto electricians
Learn a trade most garages cannot cover, from the basics to your first real jobs.
Complete beginners
No background needed. Everything is shown step by step on real cars.
Why no course can teach you every car
Every car, control unit and software is different. Adding a key to a 2006 Golf is not the same job as on a 2018 BMW.
So this course teaches how the systems work, how to research a car you have never done, and walks you through real jobs. Your first ones are not a guess.
What you will learn
- Diagnostics with OBD2 scanners: fault codes, live data and finding the real cause
- Finding electrical problems: power, ground, wiring and sensors
- Coding, hidden settings, service resets and adaptations
- Key programming: adding keys, all keys lost and remotes
- Reading and writing ECUs, EEPROMs and immobilizer data
- ECU tuning basics and cloning control units
- How to research any job before you touch the car
- Which tools each job needs, from budget options to what I use

Hi, I'm Juraj
I'm Juraj Lukacko and I work as an auto electrician. On this site I share what I learn from real work on real cars, to help you pick the right tools for diagnostics, programming and tuning and get the job done.
My Udemy courses (2,600+ students) are short introductions to single topics. This is my only complete auto electrician course: the full path from the basics to doing real jobs for customers.
