• using a second processor, in parallel with the first process, verifying biometric information of a user;
• using the first processor, after instructing the vehicle to release the steering lock:
• receiving verification of the biometric information from the second processor;
• and
• upon receipt of the verification of the biometric information, instructing the vehicle to deactivate the immobilizer;
• and
