As a car enthusiast who loves working on my own vehicles, I’ve tried several scan tools over the years-but none have impressed me as much as the Autel MaxiCheck MX900. At around $500, this Automotive Diagnostic System is an absolute game-changer for DIYers and home mechanics who want professional-grade diagnostics without the professional price tag.
What Makes the MX900 Stand Out?
- Incredible Value for Money
For$500, the MX900 offers features you‘d typically find in tools costing two or three times more. I’ve used high-end scanners before, and the MX900 holds its own with capabilities like bidirectional controls, live data streaming, and full-system scanning. It supports a wide range of manufacturers – even some less common ones – making it versatile for various makes and models.
- Key Fob Programming -A Game Changer
One feature that alone justifies the cost is key fob programming. I successfully programmed multiple key fobs for different Toyota Prius models – something that would have cost a fortune at the dealership. After just two or three key fobs, the tool practically pays for itself.
- User-Friendly & Packed with Features
The interface is intuitive. The main tabs-Diagnostic, Service, and Hot Functions-make it easy to navigate. Under “Hot Functions,”you’ll find options for programming keys, tire size calibration, ABS brake bleeding, oil reset, and more. The bidirectional controls let you activate components like the fuel pump, AC relay, and transmission solenoids, which is incredibly helpful for testing and diagnostics.

- Detailed Live Data & Special Functions
The live data section is rich with useful information:fuel trims, injector pulse width, misfire counters, sensor readings, and much more. The “Special Functions“tab includes cylinder balance tests, fuel trim resets, and crankshaft position learning – features usually reserved for expensive professional tools.
- Reliable & Comprehensive Scanning
I tested it on my 2003 Chevy Silverado and a Toyota Prius.The auto-scan function quickly checked all systems, displayed trouble codes, and allowed me to view freeze frame data and system status. Clearing codes and running tests was seamless.

Any Downsides?
Some advanced functions are vehicle-dependent, meaning not every feature works on every car. But that’s true for most scanners. The important thing is that the core diagnostics, live data, and key programming worked flawlessly on the vehicles I tested.
Final Verdict
If you’re a DIYer or a home mechanic looking for a powerful, reliable, and feature-packed scan tool around $500, the Autel MX900 is hard to beat. It‘s saved me time and money, and its professional-level functions have made complex jobs much simpler.
Highly recommended for anyone serious about car repair and diagnostics. This tool is a smart investment that delivers well beyond its price.
