BMW key programming can be a complex process, requiring specialized software and tools. Whether you’re a professional locksmith or a BMW owner dealing with a lost or malfunctioning key, understanding the options available for Bmw Key Programming Software is crucial. This guide delves into the functionalities and applications of Autohex II, a leading solution in the market.
Understanding BMW Key Management with Autohex II
Autohex II provides a comprehensive suite of functions for managing BMW keys. This software allows users to perform various actions, including:
- Checking Key Status: Instantly determine if a key is working, blocked, or currently in the ignition. The software provides a live, auto-refreshing list displaying the status of each key.
- Saving and Deleting Key Data: Autohex II enables users to save key data for use in another vehicle. This is particularly useful when transferring keys between cars or when dealing with a vehicle with no working keys. After saving the data, the original key can be deleted from the CAS for security.
- Blocking and Unblocking Keys: Control key access by blocking and unblocking keys as needed, offering an additional layer of security.

Programming Keys: Different Approaches with Autohex II
Autohex II offers flexibility in key programming methods, catering to various scenarios:
Programming via Ignition Slot
For non-encrypted CAS modules (CAS1, CAS2, CAS3), Autohex II allows key programming directly through the ignition slot. This method eliminates the need for a separate key programmer or a prepared key. However, this method is not compatible with encrypted CAS3+ modules or used keys. Primarily, this function supports programming transponders (PCF7936).

Important Note on Transponder Programming: BMW CAS operates in Crypto mode, while PCF7936 transponders default to Password mode. Before programming, ensure the transponder is switched to Crypto mode using a tool like the Microtronik HTag Pro.
Programming with a Prepared Key
This method supports all BMW key types (transponder, remote, keyless go) and works with both blank and used keys. For blank keys, the Microtronik HTag Pro is required. Autohex II prepares the key, generates a data file, and transfers the data to the CAS. For encrypted CAS3+ modules, a working key might be necessary, or the “All Keys Lost” function should be utilized.

Programming Keyless Go Keys
Autohex II can program Keyless Go keys for E-series models equipped with this feature. Ensure the key slot is in position 1 or 2 and the Key Status Field displays “005B00” before initiating the programming process.

All Keys Lost Scenario
Autohex II offers a powerful solution for programming keys when all keys are lost. The software guides the user through the necessary steps, which may involve obtaining the ISN (Individual Serial Number) from the DME (Digital Motor Electronics) or using the HTag Pro to prepare a key. This process can take up to 30 minutes, depending on the CAS version.
