How to Use TOOL32 to Delete BMW Lost Keys A Comprehensive Guide

Losing the keys to your BMW can be a stressful experience, but with the right tools and knowledge, you can regain control over your vehicle's security. In this article, we will guide you through the process of using TOOL32, a powerful software tool, to delete lost keys from your BMW's CAS module. By following these step-by-step instructions, you'll be able to remove the lost key from the system and ensure the security of your vehicle

Step 1: Run TOOL32 and Load CAS.prg File
To begin, launch the TOOL32 software on your computer and locate the CAS.prg file. Load the file within the software interface, which will allow you to access the CAS module and perform the necessary actions.

Step 2: Find the Key Number
Within the TOOL32 software, use the search function to locate the "Status-aktuell_Schluessel" option. Double-click on it to open the corresponding window. On the right side of the window, you will find the "key_number" parameter, which will display the key number associated with the keys stored in the CAS module.

Step 3: Check the Number of Keys Stored
Next, use the search function within TOOL32 to find "statusschluessel_frei_gesperrt" and double-click on it. This action will allow you to view the keys stored in the CAS module. If you find that there are two working keys already present, you can proceed to Step 4. However, if there is only one working key or none at all, you will need to use another functioning key to read the key information and determine the number of key licenses and CAS key licenses stored.

Step 4: Determine the Number of Locked Keys
Using the search function once again, look for "steuern-schluessel_gesperrt". In this window, you will find the parameter value representing the number of keys. Identify the key that you have lost, whether it is key 1 or key 2, and click on the "Clear" button to initiate the deletion process.

Step 5: Check for Key Lock Status
To ensure that the key has been successfully deleted and is no longer active, search for "Statusschluessel_frei_gesperrt" within TOOL32 and double-click on it. This action will allow you to check if the key has been locked. If you find that the key is locked, it indicates that the deletion process was successful and the lost key has been removed from the CAS module.

Using TOOL32 to delete lost keys from your BMW's CAS module is an effective way to maintain the security of your vehicle. By following the outlined steps in this guide, you can navigate the TOOL32 software and perform the necessary actions to remove the lost key from the system. Remember to exercise caution and ensure that you are comfortable with the process before proceeding. In case of any uncertainties or difficulties, it is always recommended to seek professional assistance from a qualified BMW technician or locksmith.
