OEM used key (original from another car)
Everything works perfectly, remote works on both.
But on used OEM can’t change ID, so you can’t go to dealer with this key.
This key is not a copy like BMW.
You have to solder to write data to new key.
And then perform key learning.
(Or can generate dealer key wireless on KD key and learn).

If you work on modern cars — especially BMWs and other European models — you’ve likely faced the challenge of key programming or ECU replacement. I recently tested the OTOFIX IM1 Key Programmer, a combined diagnostic and key programming tool designed for professionals and advanced DIYers. Here’s a hands-on look at what it offers.
What is the Otofix IM1?
The OTOFIX IM1 is an all-in-one tablet-based tool that merges advanced diagnostics with full-featured immobilizer and key programming functions. It’s developed in collaboration with Autel, using licensed software, and is built in Germany. Unlike its sibling, the OTOFIX D1 (which is mainly a diagnostic tool), the IM1 is geared toward key and ECU work.
Features & Capabilities
Supports smart key, semi-smart key, and chip key programming for brands like BMW (CAS 1–4, FEM/BDC), Volkswagen, Toyota, Ford, Mitsubishi, and Rolls-Royce.
Allows cloning and replacement of ECUs for several manufacturers (BMW support is planned but not yet active at time of testing).
Includes adapters and an EPROM reader for reading ISNs and performing bench programming on modules like FEM and CAS when OBD programming isn’t possible.
Available via a $180 yearly subscription, offering full system scans, coding, and adaptations.
Comes with the IM1 tablet, key programming station, EPROM reader, multiple adapters, USB cables, and a protective hard case.
Tested Vehicle & Performance
In this evaluation, the tool was demonstrated on a BMW F-Series vehicle. The Otofix IM1 successfully accessed the immobilizer system, read CAS data via bench connection, and prepared a new key using the included programmer. The process required technical knowledge but was streamlined thanks to the clear UI and dedicated hardware.
IM1 vs. D1: Which to Choose?
Otofix D1: Priced around £459, it includes full diagnostics and service functions but no key programming or ECU replacement capabilities.
Otofix IM1: Priced around £699, it includes all key and ECU programming features, but diagnostics require the extra $180 subscription.
For most users who need key programming, the IM1 is the better long-term investment. It avoids the need for multiple devices.
Pros & Cons

Cons:
Final Recommendation
The Otofix IM1 is a professional-grade tool ideal for auto locksmiths, independent workshops, and experienced enthusiasts who regularly handle key programming or ECU work. Its build quality, included accessories, and focused functionality make it a worthwhile investment.
If you already own a capable diagnostic tool and mainly need key programming, the IM1 is an excellent standalone solution. If you need both diagnostics and programming from one device, the IM1 plus the diagnostics subscription offers a complete package.
Best for: BMW specialists, auto locksmiths, and advanced DIYers working with European vehicles.
Value: Rated excellent for its niche — it can pay for itself quickly in professional use.
