## Abstract

An apparatus and method for digital decoding and deciphering a lock cylinder pin configuration, such as for a Kwikset or a Smart Key lock is disclosed. The digital decoder includes a light source placed inside of the keyhole that eliminates glare from the face of the lock and improves the decoding process. A digital camera is configured to provide an optical view of an interior of the lock cylinder to detect the pin settings for each of a plurality of lock tumbler pins carried by the lock cylinder. The digital camera is configured to provide a live feed displayed on a video screen or recorded for later analysis.

## Claims

### Claim 1

A lock cylinder decoding apparatus for decoding a lock cylinder of a lock, comprising:
a housing having a proximal end and a distal end;
a camera mounted within the proximal end of the housing;
a modified key removably coupled to the distal end, the modified key having a profile dimensioned to fit a corresponding profile of the lock cylinder, a channel defined within the profile has an opening to a pin side of the lock cylinder; and
a mirror attached at a distal end of the channel, wherein the mirror is angled to orient a sight line of the camera on a selected pin of a plurality of pins carried by the lock cylinder to provide a visual observation of the selected pin by the camera.

### Claim 2 (depends on 1)

The lock cylinder decoding apparatus of claim 1, further comprising:
a camera lens configured to provide a point of focus on the selected pin carried within the lock cylinder.

### Claim 3 (depends on 2)

The lock cylinder decoding apparatus of claim 2, wherein the camera lens protrudes into a base of the modified key.

### Claim 4 (depends on 1)

The lock cylinder decoding apparatus of claim 1, further comprising:
a light source oriented along the sight line of the camera to illuminate the selected pin.

### Claim 5 (depends on 4)

The lock cylinder decoding apparatus of claim 4, wherein the light source is carried within the modified key.

### Claim 6 (depends on 5)

The lock cylinder decoding apparatus of claim 5, wherein the light source is carried within the channel.

### Claim 7 (depends on 5)

The lock cylinder decoding apparatus of claim 5, further comprising:
an electrical contact between the modified key and the housing.

### Claim 8 (depends on 1)

The lock cylinder decoding apparatus of claim 1, further comprising:
a plurality of spacers corresponding to the plurality of pins carried by the lock cylinder, each of the plurality of spacers configured to be coupled to the modified key, each of the plurality of spacers having a thickness to position the mirror for observation of the selected pin corresponding to a selected one of the plurality of spacers.

### Claim 9 (depends on 1)

The lock cylinder decoding apparatus of claim 1, further comprising:
the mirror attached at the distal end of the channel, the channel having a depth corresponding to a last pin of the plurality of pins carried by the lock cylinder.

### Claim 10 (depends on 1)

The lock cylinder decoding apparatus of claim 1, wherein the camera is a digital camera.

### Claim 11 (depends on 10)

The lock cylinder decoding apparatus of claim 10, further comprising:
a display coupled to the digital camera.

### Claim 12 (depends on 11)

The lock cylinder decoding apparatus of claim 11, further comprising:
a wireless communications module configured for communication with a mobile computing device.

### Claim 13

A method of decoding a lock cylinder having a plurality of pins, comprising:
inserting a modified key removably coupled to a distal end of a lock cylinder decoding device, the modified key having a profile dimensioned to fit a corresponding profile of the lock cylinder, a channel defined within the profile has an opening to a pin side of the lock cylinder, a mirror attached at a distal end of the channel, wherein the mirror is angled to orient a sight line of a camera carried by the lock cylinder decoding device on a distal pin of the plurality of pins carried by the lock cylinder to provide a visual observation of a selected pin by the camera.

### Claim 14 (depends on 13)

The method of decoding of claim 13, further comprising:
withdrawing the modified key to orient the sight line on each of a preceding pin of the plurality of pins in the lock cylinder.

### Claim 15 (depends on 13)

The method of decoding of claim 13, further comprising:
applying a spacer to the modified key, the spacer selected from a plurality of spacers dimensioned to position the sight line of the camera on each of a preceding pin of the plurality pins in the lock cylinder.

### Claim 16 (depends on 13)

The method of decoding of claim 13, further comprising:
observing a pin depth of each of the plurality of pins in the lock cylinder by the camera.

### Claim 17 (depends on 15)

The method of decoding of claim 15, further comprising:
cutting a key based on the pin depth of each of the plurality of pins in the lock cylinder.
