Autel MaxiIM IM508S

Autel MaxiIM IM508S — Key Fob Programmer and IMMO Tablet

The IM508S is Autel's mid-range immobilizer and key programming tablet — a 7-inch Android touchscreen that combines full-system diagnostics, 40+ service functions, and IMMO key programming in one portable device. It ships with the XP200 key programmer and handles most U.S. and Asian vehicle IMMO jobs via OBD. If your shop is ready to bring key programming in-house and does not yet need the European-heavy feature set of the IM608 PRO II, the IM508S is the logical entry point.

Note: Autel key programming and IMMO products are designed for professional locksmiths and NASTF-registered Vehicle Security Professionals. Ensure you meet local licensing requirements before purchasing.

What the IM508S Does

The IM508S handles the full range of IMMO and key programming functions for most domestic and Asian vehicles:

• All-Keys-Lost (AKL): Read PIN/CS directly from the vehicle, generate keys without an existing working key
• Key Generation: Create new keys from the vehicle's IMMO data
• Key Learning: Program new keys to the vehicle's IMMO ECU
• Remote Learning: Program remote functions to the vehicle
• Smart Mode: Guided, automated key learning for technicians newer to IMMO work
• Expert Mode: Advanced manual workflow for experienced IMMO technicians
• IMMO ECU Functions: Reset, adaptation, refresh, and coding
• IKEY Programming: Program Autel's full IKEY line using the XP200 programmer

Beyond key programming, the IM508S functions as a full-system code reader and service tool:

• All-systems diagnostics for US, Asian, and European vehicles, 1996 and newer
• Read/erase codes, live data, freeze data, ECU information, active tests
• 40+ service functions including EPB, DPF, SAS, Oil Reset, and BMS
• Auto VIN for quick vehicle identification

IM508S vs. IM508 — What Changed

The IM508S is a meaningful upgrade over the original IM508:

• Processor: 1.8 GHz Cortex-A55 vs. 1.6 GHz Cortex-A9 — noticeably faster in practice
• OS: Android 11 vs. Android 4.4.4 — current software support, better security
• Memory: 4 GB RAM + 64 GB vs. 1 GB RAM + 32 GB — no performance bottlenecks
• SD Card: Supports up to 64 GB vs. 32 GB

If you have an original IM508 and are considering an upgrade, the IM508S is a worthwhile step up. Key coverage and IMMO functionality are the same; the hardware is substantially faster.

IM508S vs. IM608 PRO II — Which Do You Need?

The IM508S handles most U.S. and Asian vehicles well. If your work is primarily domestic and import shops — Nissan, Honda, Hyundai, GM, Ford, Chrysler — the IM508S has the coverage you need.

Step up to the IM608 PRO II ($2,295+) if you need:

• Broader European coverage (BMW, Mercedes, VW/Audi) for AKL
• The XP400Pro programmer for advanced chip and key operations
• J2534 pass-through for dealer-level programming via JVCI
• 10.1-inch screen for more comfortable workflow

Annual Updates: IM5081YRUPDATE Total Care Program

The IM508S ships with one year of software updates included. After the first year, continuing updates requires the IM5081YRUPDATE Total Care Program (TCP) at $349/year. Updates keep your vehicle coverage current and add newly supported makes, models, and IMMO procedures as Autel releases them.

What Is Included

• Autel MaxiIM IM508S Tablet (Android 11, 7-inch)
• XP200 Key Programmer
• OBD-II Cable
