Summary:
- For full diagnostics + key programming (premium): Autel MaxiIM IM608 Pro II is the best, offering the most complete and advanced set of features.
- For key programming + basic diagnostics (mid-range): Autel MaxiIM IM508S is a great value with strong capabilities but fewer advanced diagnostic features compared to the IM608 Pro II.
- For key programming (entry-level to mid-range): OTOFIX IM2 offers a good balance of price and advanced key programming features for locksmiths or small shops.
- For basic key programming (budget): OTOFIX IM1 is ideal for entry-level users who need only basic key programming functionalities.
Your choice ultimately depends on the depth of diagnostics and key programming you require, along with your budget. If your focus is primarily key programming with some diagnostic features, the OTOFIX IM2 and IM1 are strong contenders. However, for a tool that balances both advanced diagnostics and key programming, the Autel MaxiIM IM508S or IM608 Pro II would be more suitable, with the IM608 Pro II being the top-of-the-line option for those needing maximum functionality.
