High Security Areas, such as Groom Lake, don't use Keys anymore, they use so-called bionic locks. These locks recognize unique personal features of
authorized personnel (Such as: Hand Prints, Retna patterns(the layout of the blood vessals at the back of the eye), or unique characteristist of your
voice. In most of these places, you scan your badge to tell the computer who is requesting entry, and then you have to provide a bionic confirmation
of identity, such as hand prints to athenticate your identity. If both the badge AND the Bionic confirmation match the same person in the data base,
you are allowed to enter, if not, an alarm goes off, and security doors closes, trapping you there until the security police get you out.
Of course, if you WANT to get Arrested by two MP's with M-16's, you can always skip the badge and just TRY to walk right in!
