5 Autel Key Programming Tool Picks: IMMO & KM100 Compared

Choosing the right Autel key programming tool can make or break your efficiency when working on vehicle keys and immobiliser systems. Whether you're a professional locksmith building out your kit or a DIY enthusiast looking for reliable equipment, Autel's range offers options at various price points and capability levels.

At Rush Auto Locksmiths, we've used and tested multiple key programming devices across thousands of jobs throughout Blackpool and North West Lancashire. That hands-on experience gives us practical insight into what actually matters when these tools meet real-world vehicles, not just what looks good on a spec sheet.

This guide breaks down five Autel key programming tools, from the compact KM100 to the full-featured IMMO series. We'll compare their capabilities, pricing, and ideal use cases so you can pick the right tool for your specific needs.

1. Autel MaxiIM KM100

The KM100 sits at the entry point of Autel's key programming range, offering portable functionality in a tablet-sized package. This Autel key programming tool works well for locksmiths who need basic key programming on the go without the bulk of larger diagnostic platforms. You get solid coverage across common vehicle makes, though it lacks the depth of Autel's IMMO series for advanced functions.

Key programming and IMMO capabilities

You can handle all-keys-lost situations on many popular vehicle brands with the KM100, including VW, Audi, BMW, Mercedes, and Ford. The device performs EEPROM reading for immobiliser data and supports both proximity keys and standard transponders. Coverage extends to approximately 70+ makes, though some newer models require firmware updates.

The KM100 handles most mainstream vehicles but won't tackle every specialist or commercial vehicle you encounter.

Diagnostics and extra features

Beyond key programming, you get basic OBD diagnostics for reading and clearing fault codes across engine, transmission, and ABS systems. The KM100 includes service functions like oil reset and EPB calibration, making it more versatile than a dedicated key tool. Its 5-inch touchscreen runs Android, giving you a familiar interface that responds quickly during jobs.

What you need to use it

Your KM100 connects to vehicles through the included OBD cable, and you'll need a stable internet connection for updates and online functions. Battery life runs around 8 hours of active use, so you can work through most days without recharging. The device comes with one year of free updates, after which you'll pay annual subscription fees.

Typical price in the UK

Expect to pay between £1,200 and £1,500 for a new KM100 kit depending on the supplier and any bundled accessories. This positions it as an affordable entry point for professional locksmiths starting out or mobile technicians adding key programming to their services.

2. Autel MaxiIM IM508S

The IM508S steps up from the KM100 with a larger 7-inch screen and deeper vehicle coverage across both key programming and diagnostics. This Autel key programming tool targets professional locksmiths who need more than basic functions but don't require the XP400 key cutting module that comes with higher-tier models. Your workflow speeds up with faster processing and expanded IMMO functions.

Key programming and IMMO capabilities

You gain access to over 80 vehicle makes with the IM508S, including more comprehensive coverage of European and Asian manufacturers. The device handles advanced key learning on vehicles with encrypted immobiliser systems and supports bidirectional control for actuator tests. Your all-keys-lost scenarios become more manageable with expanded dealer-level functions.

Diagnostics and extra features

Full-system diagnostics let you scan all control modules simultaneously, not just powertrain components. You can perform 31 service functions including DPF regeneration, throttle adaptation, and battery registration across most modern vehicles.

The IM508S gives you genuine diagnostic depth alongside key programming, making it a proper dual-purpose tool.

What you need to use it

Your IM508S requires the XP200 key programmer (sold separately at around £350) to perform most key programming functions. You'll need regular internet access for software updates and online authentication. Battery life extends to 10 hours with the larger capacity pack.

Typical price in the UK

Budget between £1,800 and £2,200 for the IM508S base unit, plus the cost of your XP200 programmer if you don't already own one.

3. Autel MaxiIM IM508S Pro

The IM508S Pro bundles the XP400 key cutting module with the IM508S base unit, giving you a complete key solution in one package. This Autel key programming tool eliminates the need for separate cutting equipment on most jobs, letting you program and cut keys at the vehicle in true mobile fashion. Your investment jumps compared to the standard IM508S, but you gain significant workflow efficiency.

Key programming and IMMO capabilities

Your vehicle coverage matches the standard IM508S with over 80 makes supported, but the XP400 module adds mechanical key cutting for all standard blade types. You can handle Mercedes laser keys, BMW profile keys, and standard double-sided transponders without returning to your workshop. The built-in key database contains over 1,000 cutting patterns.

Diagnostics and extra features

Diagnostic functions remain identical to the IM508S base model, with full-system scanning and 31 service functions across all modules. The XP400 integration means your device stores cutting codes alongside programming data.

The Pro version saves you multiple trips between vehicle and workshop when customers need both programming and cutting.

What you need to use it

Your setup requirements mirror the standard IM508S, though the XP400 module needs fresh cutting blades stocked for different key types. Battery life drops slightly to 8 hours when actively using the cutting function.

Typical price in the UK

Expect to pay between £2,400 and £2,800 for the complete IM508S Pro package with XP400 included.

4. Autel MaxiIM IM608 Pro

The IM608 Pro represents Autel's professional-grade platform, combining advanced diagnostics with comprehensive key programming in a single robust unit. This Autel key programming tool targets established locksmiths and automotive workshops that need dealer-level capabilities across the widest possible vehicle range. Your investment increases substantially, but you gain access to functions that budget tools simply cannot replicate.

Key programming and IMMO capabilities

Coverage extends to over 90 vehicle makes with the IM608 Pro, including specialist brands and commercial vehicles that entry-level tools miss entirely. You can perform J2534 programming for manufacturer software updates and access encrypted immobiliser systems on the latest European and Asian models. The included XP400 Pro module handles both standard and laser key cutting with enhanced precision.

Diagnostics and extra features

Your diagnostic capabilities reach genuine dealer level with topology mapping, module coding, and component replacement adaptation across all vehicle systems. You get ECU programming functionality that lets you install new control modules and perform complete vehicle reprogramming when required.

The IM608 Pro eliminates most situations where you'd need to refer customers back to main dealers for programming work.

What you need to use it

Your IM608 Pro requires annual subscription renewal for software updates and continued access to online functions. Battery performance delivers 10 hours of mixed use, though heavy diagnostic sessions drain power faster.

Typical price in the UK

Budget between £3,200 and £3,800 for a complete IM608 Pro system with XP400 Pro included.

5. Autel MaxiIM IM608S II

The IM608S II represents Autel's flagship key programming platform, incorporating the latest hardware and software advances from their development team. This Autel key programming tool delivers faster processing speeds and expanded vehicle coverage compared to the IM608 Pro, making it the choice for high-volume workshops that demand maximum capability. Your investment reaches the top of Autel's range, but you gain access to cutting-edge functions as they release.

Key programming and IMMO capabilities

Vehicle coverage extends beyond 95 makes with the IM608S II, including the newest electric and hybrid models that earlier tools cannot access. You can perform remote programming via cloud services for select manufacturers, eliminating physical trips to vehicles in some situations. The upgraded XP400 Pro module maintains all cutting functions whilst adding support for emerging key technologies.

Diagnostics and extra features

Your diagnostic capabilities include advanced driver assistance system (ADAS) calibration functions that complement key programming work on modern vehicles. Processing speed increases by approximately 30% over the IM608 Pro, reducing wait times during complex programming operations.

The IM608S II future-proofs your toolkit against upcoming vehicle technologies whilst handling everything current models throw at you.

What you need to use it

Your setup requirements match the IM608 Pro, with annual subscriptions required for continued software access and updates. Battery capacity supports 10 hours of intensive use across diagnostic and programming functions.

Typical price in the UK

Expect to pay between £4,200 and £4,800 for the complete IM608S II system with all included modules and accessories.

Next steps

Your choice among these Autel key programming tool options depends on your current workload and vehicle coverage needs. Start with the KM100 or IM508S if you're building foundational capabilities, then upgrade to the Pro or II models as your business demands expand. Check your most common vehicle makes against each tool's coverage database before purchasing, as gaps in your typical customer base will create frustration quickly.
