Autel MaxiIM IM508S Key Programmer and Diagnostic Scanner - IMMO Key Programming, All Systems Diagnostics, Android 11, 7in Touchscreen

A professional key programming and diagnostic tool for locksmiths, independent workshops and serious mobile technicians.

Key and immobiliser programming

• Read PIN and CS codes, including all keys lost situations
• Key generation, key learning and remote learning
• Automatic detection of vehicle make, model, year and system
• IMMO ECU reset, adaptation, refresh and coding
• Backup and restore of IMMO data

Full diagnostics, not just keys

The IM508S runs all-systems diagnostics on US, Asian and European vehicles from 1996 onwards, covering engine, transmission, ABS, SRS, TPMS, EPB, DPF, SAS and more. The service menu includes oil light reset, BMS registration, brake bleeding, throttle, injector, seat and suspension work.

Bi-directional control

Rather than guessing at a fault, the IM508S sends commands directly to the vehicle's ECU to actuate components - ABS pumps, windows, doors, solenoids, valves, wipers and headlamps - so you can confirm whether a part is actually dead before you start dismantling anything.

Important compatibility notes

Please read these before ordering, since key and IMMO coverage is not universal:

• Send us the 17-digit VIN along with the make, model and year so we can confirm the functions you need are supported on your vehicle.
• Since 25 August 2025, IMMO functions for Ford have been significantly limited in North America. Send the VIN for a compatibility check if Ford IMMO work matters to you.

Frequently asked questions

Will it work on my car?
Key and IMMO functions vary by make, model, year and region. Send us the 17-digit VIN with the make, model and year and we will check before you buy.

What is the difference between the IM508S and the Pro versions?
The Pro configurations add programming capability and accessories. The Pro Full Set and the Pro with APB112 and G-Box 3 bundle in adapters that otherwise cost extra.

Do I need the G-Box 3 or APB112?
Only for specific jobs. G-Box 3 handles key emulation and ignition coil data, while APB112 is what you want for Mercedes DAS3 all keys lost and BMW DME and DDE ISN work.

Can it do all keys lost?
Yes on many platforms, including Mercedes and VW group vehicles, but not on Toyota, Lexus or Renault in North America.
