In addition, the key fob of the present invention includes a fingerprint scanner 310 for scanning an authorized user's fingerprint, a display 330 for displaying instructional information during registration of an authorized user, and for displaying verification information when accessing the key fob of the present invention. A couple of LED lights, one green 350 for indicating that the scanned fingerprint is a fingerprint belonging to an authorized user, and a red LED 340, for indicating that the scanned fingerprint belongs to an unknown and an un-authorized user.

[0023] In another embodiment of the present invention, and in reference to FIG. 3(b), there is shown from a bottom perspective of the key fob 385, a spring-loaded cover 395 for securely storing the ignition key (see FIG. 4, #410), when the user of the key fob decides to stow away the ignition key. Once the user decides to stow away the ignition key by pushing button 380, the spring-loaded cover 395 is pushed back in place by the spring 360 to cover the opening where the ignition comes out. Likewise, when the user pushes down on button 370, the verification process as discussed in the first embodiment above, and once the user is verified, the ignition key is released, pushing the spring-loaded cover 395 out. In a different variation of the present invention, the spring-loaded cover 395 is electrically connected to the solenoid (item 640) shown on FIG. 6 for electro-mechanically opening and closing the spring-loaded cover 395 during the ignition key activation and de-activation processes.

[0024] In another embodiment and in reference to FIG. 4, the improved key fob 400, includes a block 440 containing a fingerprint scanner 450 for scanning fingerprint of a user to be authorized or a user who is already an authorized user; a notch 420 on the ignition key 410, that when the ignition key 400 is pushed back into the housing 460, the notch 420 is held by latch 430.

[0025] Referring now to FIG. 5, the user begins the process at step 505, moves on to step 510, by instructing the user to scan his or her own fingerprint by the on-board fingerprint scanner (see FIG. 4, #450) to create a profile of the user, then the process moves on to step 515 to create a security code created from a combination of letters and numbers, then in step 520 to register the user's scanned fingerprint data along with created security data, and saving it in the memory 625 of FIG. 6. Once the fingerprint scan and the security data is created for the authorized user, and he or she subsequently intends to access the automobile ignition key in order to operate the automobile associated with the automobile ignition key in step 525. The system then moves onto step 530, to check whether the user attempting to access the automobile ignition key is registered and is an authorized user, the method moves onto step 565, where the authorized user is requested to scan his or her fingerprint. The scanned fingerprint is analyzed and verified in step 570; if the verification fails, the scanned fingerprint is re-verified, if a secondary verification is required, the user is required to input his or her security code via the display. When the controller of FIG. 6 determines that the user is an authorized user the inputted code is the correct code in step 505, the user is allowed access to the key fob in step 506 and may open the key fob in step 507. When the controller of FIG. 6 ascertains that the scanned fingerprint is verified, the automobile ignition key is released for potential use by the user. in step 570.

[0026] Furthermore, and going back to step 530, where the system checks whether the user is a registered user, if the answer is No, the step of checking whether the un-registered new user is someone the owner of the automobile key fob is allowing to be authorized to be registered in step 535. The system then moves onto step 540 where the new authorized user's fingerprint is scanned, if the scan is successful in step 545, the data associated with the scanned fingerprint is recorded in step 550, and the registration process for the new authorized user ends in step 555. If the scan is unsuccessful, the fingerprint scanning is repeated until it is successful. If the user is not a newly authorized user, the accessing process is rejected in step 560.

[0027] Referring now to FIG. 6, there is shown a block diagram of new and improved automobile key fob of the present invention. It includes a power source 610, typically are small dry-cell batteries, sealed, non-rechargeable AA, 9-volt.
