A lost car key or a desired spare key is one of the best-paid jobs that can come into an independent workshop – provided the right device is on hand. Because not every key programming device can handle every brand, every immobilizer system or every "All Keys Lost" scenario. Which device is right for you mainly depends on which vehicle brands are most common in your workshop, which additional programming hardware is needed, and how deep the diagnostic functions should go beyond pure key programming.
Which vehicle brands does a key programming device cover?
The two Vident iSmart models (810 IM and iSmart920 IM) cover over 110 vehicle brands up to model year 2025 according to manufacturer data, while the AUTEL IM608 Pro II focuses on over 80 manufacturers from Europe, the USA and Asia – but with particular depth on complex immobilizer systems. The Vident devices are thus designed as a broad multi-brand solution for classic daily workshop use: from Audi, BMW, Mercedes-Benz and Volkswagen to Opel, Ford, Toyota and Hyundai, and numerous other European, Asian and American brands. It's important to note: as with any multi-brand diagnostic tool, the key and diagnostic functions specifically available always depend on the vehicle manufacturer, model, model year and installed control unit – "over 110 brands" does not mean that every brand offers the full range of functions on every model.
The AUTEL IM608 Pro II takes a different approach: instead of relying purely on the number of brands, it specializes in OE-level professional diagnostics and demanding key programming, with particularly strong support for BMW, Mercedes-Benz, Audi and Volkswagen – exactly the brands where immobilizer and key systems are, in practice, the most complex to work with.
What additional hardware do I need for key programming?
Depending on the vehicle, the Bluetooth VCI box integrated in the device is enough for simpler key jobs, while more complex systems require additional, included programming hardware. On the Vident iSmart 810 IM, this is the Bluetooth VCI box along with an OBD2 adapter and diagnostic cable – sufficient for the key and immobilizer functions stored in the device. The Vident iSmart920 IM additionally comes with several vehicle-specific adapters and boards (including VW001, VW002, VW003, VP001 module as well as VB001 and VB002 boards plus an RF100 module), which are needed for deeper key and IMMO work on certain vehicle types.
The most extensive included additional hardware is with the AUTEL IM608 Pro II: it's supplied complete with the XP400 Pro, a standalone programming device for reading and writing EEPROM and MCU data as well as transponder analysis, and with the G-Box 3, which was specifically developed for key work on BMW (including FEM/BDC control units) and Mercedes-Benz vehicles and significantly speeds up the programming process, especially in "All Keys Lost" cases – when no working key is left.
What diagnostic functions do the devices offer in addition to key programming?
All three devices are full-featured diagnostic tools, not pure key programming devices – the key function comes in addition to normal vehicle diagnostics on all three, not as a replacement for it. Reading and clearing fault codes, displaying live data in real time, freeze frame data, and common service functions such as oil service reset, ABS/SRS diagnostics, DPF regeneration, electronic parking brake (EPB) and steering angle sensor calibration are part of the feature set on all three models.
The Vident iSmart 810 IM offers more than 40 service functions combined with key and immobilizer diagnostics. The Vident iSmart920 IM adds dedicated IMMO functions such as key learning, PIN and CS reading (model-dependent) and remote control learning. The AUTEL IM608 Pro II goes the deepest: alongside AutoVIN vehicle identification, active tests and bidirectional control, it supports, in the key area, functions such as programming new keys, deleting lost keys, learning remote controls, programming transponders and complete "All Keys Lost" programming – either in the guided Smart mode or in Expert mode for experienced users. As always: the functions actually available always depend on the vehicle, model and control unit.
Which key programming device is best?
There is no single best key programming device – the right choice depends on the workshop's vehicle base and budget: for classic daily workshop use with a mixed vehicle base and a limited budget, the Vident iSmart 810 IM (€1,299.00) is the most economical choice; for workshops with more demanding key work and a need for additional adapters, the Vident iSmart920 IM (€1,399.00) is better suited; and for professional key services and workshops with frequent BMW/Mercedes-Benz jobs and "All Keys Lost" cases, the AUTEL IM608 Pro II (€3,899.00) is, despite the higher price, the most capable solution, because the G-Box 3 and XP400 Pro are already included and don't need to be purchased separately later.
Anyone just getting started with key programming and primarily servicing everyday European, Asian and American vehicles will generally be up and running faster with one of the two Vident models and will pay off the investment more quickly. Anyone who already regularly handles more complex cases – such as lost keys on current BMW or Mercedes-Benz models – saves on later purchasing the XP400 Pro and G-Box 3 separately with the AUTEL IM608 Pro II and works directly at OE level.
Comparison table: which device suits which area of use?
| Area of use | Recommendation | Price |
|---|---|---|
| Entry into key programming, mixed vehicle base, smaller budget | Vident iSmart 810 IM | €1,299.00 |
| Extended key and IMMO work with additional vehicle-specific adapters | Vident iSmart920 IM | €1,399.00 |
| Professional workshop/key service focused on BMW & Mercedes-Benz, "All Keys Lost", OE level | AUTEL IM608 Pro II with G-Box 3 | €3,899.00 |
