Autel MaxiIM IM508S Automotive Scan Tool with XP200 Key Programmer

Key Programming Functions

The key programming functions of the Autel MaxiIM IM508S are really its most impressive offering. Not only does it read, generate, and learn keys, you can also reset or code the car's ECU and MCU. This gives you full control over all the keys for the vehicle.

The MaxiIM IM508S can also reprogram IMMO functions connected to keys. Even if all the old keys have been lost, you can remove the immobilizing mechanisms and get the vehicle up and running again. Once you do, you can refresh the IMMO systems, making sure the customer's car is still protected.

Since the Autel MaxiIM IM508S has built-in Wi-Fi, it also offers remote key learning. You can reset, generate, or relearn keys from anywhere in your garage. One thing to keep in mind is that not all functions are remote-capable. You will need to be connected to the XP200 key programmer to read or write the ECU, or for specialized functions like reading IC cards, infrared keys, and encryption chips.

Diagnostic Features

Along with being a powerful key programmer, the Autel MaxiIM IM508S is an impressive diagnostic tool. It provides all the basic service and diagnostic functions you'd get from a typical high-end OBD2 scan tool. In fact, many of these functions are the same as those found on other professional Autel scanners, like the Maxisys MS906 Pro.

Autel MaxiIM IM508S includes 40+ maintenance functions

Autel MaxiIM IM508S includes 28+ maintenance functions

All-told, the Autel MaxiIMS IM508 includes 28+ maintenance functions. Along with the standard service functions like EPB, SAS, and oil light reset, it has capabilities that are harder to find in hand-held scan tools. The highlights in our book include:

  • Resetting TPMS sensors. Often, you need a dedicated TPMS tool for this function, but it's built into the MaxiIM IM508S. That's helpful for quickly accessing the tire sensor ID in the ECU, as well as performing tests and replacements.
  • Battery Management System (BMS). You can do a lot more than just re-set the battery light or register an after-market replacement. The MaxiIM IM508S also lets you reprogram for variations in battery capacity and monitor the voltage and charge.
  • Diesel Particulate Filter System (DPF). With this tool, you can manage the DPF regeneration of any compatible diesel engine. It also allows you to adapt the ECU when you replace or repair the system

As far as the diagnostics go, the Autel IM508S is as comprehensive as any OBD2 scanner on the market. It gives you access to all 10 OBD2 modes, as well as a host of system tests for specific components. You'll especially love how easy it is to read and clear any diagnostic trouble codes, and you can switch quickly between live data streams.

Vehicle Coverage

When it comes to diagnostic functions, the Autel MaxiIM IM508S works with over 80 different manufacturers from North America, Europe, and Asia. Compatibility for the key programming functions is more limited, however, especially when it comes to IMMO and ECU reprogramming.

Unfortunately, the full key programming compatibility of the IM508S isn't easy to find. If you're concerned about a specific vehicle's compatibility, please reach out to the company directly to take further confirmation. Also, you can contact us and send the VIN number to to check compatibility.

Software and Updates

The touch screen interface on the Autel MaxiIM IM508S is controlled using an Android-based operating system. We found it to be responsive and easy to navigate, and it seems to multi-task well without hang-ups.

Autel provides 12 months of free software updates for its IM508S key programmer. You can access these updates directly through the scanner, thanks to the built-in Wi-Fi connection. Also, you can buy the update service from us directly: IM508S Update Service

Who is the Autel MaxiIM IM508S For?

The Autel IM508S is a professional diagnostic tool. It's designed for use by mechanics, body shops, and other professional garages. And while it's a great value for what it can do, it is priced as such—likely outside the budget range of even serious hobbyists.
