BMW key programming can be a complex process, requiring specialized tools and software. This guide delves into the intricacies of Bmw Key Programmer Software, providing locksmiths and car owners with valuable insights into key management, programming procedures, and solutions for various scenarios, including all keys lost situations. Understanding the capabilities of advanced tools like Autohex II, paired with the Microtronik HTag Pro key programmer, is crucial for efficient and successful BMW key programming.
Managing BMW Keys with Autohex II Software
Autohex II BMW Key Programming Software provides a comprehensive suite of functions for managing BMW keys. These features empower users to:
- Check Key Status: Instantly determine if a key is working, blocked, or currently in the ignition. This live status update allows for quick diagnostics and troubleshooting.
- Identify Key Number: Easily determine the key’s slot number by simply inserting it into the ignition.
- Save Key Data: Save key data for future use, such as programming a key in a different vehicle or replacing a lost key. This function enables efficient key duplication and recovery.
- Delete Key Data: Permanently remove key data from the CAS (Car Access System) for security purposes or when replacing keys.
- Block/Unblock Keys: Disable or enable keys remotely, offering enhanced control over vehicle access.
Programming Keys: Different Approaches
Autohex II offers several methods for programming BMW keys, catering to different scenarios and CAS types:
Programming via Ignition Slot
This method works for non-encrypted CAS modules (CAS1, CAS2, CAS3). It requires a blank key and utilizes the ignition slot for programming, eliminating the need for external key programmers. However, this method is not compatible with encrypted CAS3+ systems. Furthermore, not all CAS versions support remote key programming via this method, although transponder (PCF7936) programming is generally supported for non-encrypted CAS modules.
Important Note for Transponder Programming: PCF7936 transponders must be in Crypto mode for compatibility with BMW CAS systems. Autohex II, in conjunction with the HTag Pro, facilitates switching the transponder from the default Password mode to Crypto mode.
Programming with a Prepared Key
This method supports various key types, including transponders, remote keys, and Keyless Go keys. It requires either a blank key programmed using the HTag Pro or a used key with a saved data file. For encrypted CAS3+ systems, a working key might be necessary in some instances.
Programming Keyless Go Keys
Autohex II can program Keyless Go keys, but specific considerations apply:
- Key Slot Position: The key should be in position 1 or 2 for Keyless Go functionality. Other positions will result in remote-only operation.
- Key Status Field: Ensure the Key Status Field displays “005B00” before programming. The default value for remote keys (“004B00”) will not enable Keyless Go functionality.
All Keys Lost Solution
Autohex II offers a robust solution for programming keys when all keys are lost. This function utilizes different procedures depending on the CAS version and ISN (Individual Serial Number) type. In cases requiring the ISN, it can be obtained using the Autohex II CAS DME ISN Manager. The software may offer options to use the HTag Pro to prepare a key or load a data file from a previously prepared key. This process can take up to 30 minutes, depending on the complexity of the CAS.
Conclusion
Autohex II BMW Key Programming Software, combined with the Microtronik HTag Pro, offers a comprehensive and powerful solution for BMW locksmiths and technicians. Its diverse functionality, ranging from basic key management to complex all keys lost scenarios, positions it as a leading tool in the field of BMW key programming. The software’s ability to handle various CAS types and key programming methods ensures efficient and reliable key programming for a wide range of BMW vehicles.
