a reflective surface positioned on the bottom side of the protruding portion and having a circumferential length not greater than the circumferential length of the protruding portion;

wherein the light-emitting device is positioned behind the protruding portion; and

wherein the light-emitting device, transparent portion, protruding portion and reflective surface are configured to cooperate to reflect light from the light-emitting device to illuminate the plurality of buttons.

2. The lock assembly of claim 1 , further including a light button, the light-emitting device being configured to emit the light when the light button is activated.

3. The lock assembly of claim 2 , wherein the light-emitting device is configured to stop emitting the light after a predetermined time period.

4. The lock assembly of claim 2 , wherein:

the keypad includes an orientation feature to allow an operator to find the light button in the dark; and

wherein the orientation feature includes one or more raised features formed on the light button.

5. The lock assembly of claim 1 , wherein the reflective surface includes a corrugated surface.

6. The lock assembly of claim 1 , wherein the light-emitting device is protected from an electrostatic discharge event on the keypad.

7. The lock assembly of claim 1 , wherein the lock assembly is configured to allow access to the interior region of the container upon receiving a predetermined input sequence from the plurality of buttons.

8. The lock assembly of claim 1 , wherein the circumferential length of the protruding portion is less than half the circumference of the bezel.

9. The lock assembly of claim 8 , wherein the buttons on the keypad form an array having a width, and the circumferential length of the protruding portion is less than the width of the array.

10. The lock assembly of claim 1 , wherein:

the keypad includes a housing and a top face;

the housing has a lower end and an upper end;

the lower end is disposed above the top face a greater distance than is the upper end; and

wherein the keypad is angled upward towards a user.

11. A lock assembly for securing a container having an interior region, the lock assembly including:

a keypad having a top face and a plurality of buttons mounted on the top face;

a light-emitting device; and

a bezel surrounding at least a portion of the keypad and having an outer circumference;

wherein the bezel includes a protruding portion having a circumferential length less than the outer circumference of the bezel, the protruding portion extending outward from the keypad and further including a bottom side and a reflective corrugated surface positioned on the bottom side to reflect light from the light-emitting device, the light reflected from the corrugated surface illuminating the plurality of buttons;

the corrugated surface includes a first end and a second end;

the first end is positioned closer to the top face than is the second end;

the first end is positioned closer to the outer circumference of the bezel than is the second end; and

wherein an angle is created between the reflective surface and the top face, creating a more even lighting of the plurality of buttons on the top face.

12. The lock assembly of claim 11 , wherein the corrugated surface includes a plurality of substantially parallel ridges and furrows.

13. The lock assembly of claim 11 , further comprising a gap defined between the protruding portion and the keypad, the light emitting device being positioned below the gap, and the corrugated surface being positioned above the gap.

14. The lock assembly of claim 11 , wherein the corrugated surface is chrome-plated.

15. The lock assembly of claim 11 , wherein the plurality of buttons are positioned on a first surface of the keypad and the light-emitting device is positioned on a second surface of the keypad, the first surface being opposite the second surface.

16. The lock assembly of claim 11 , wherein the lock assembly is configured to allow access to the interior region of the container upon receiving a predetermined input sequence from the plurality of buttons.

17. A lock assembly for securing a container having an interior region, the lock assembly including:

a keypad having a plurality of buttons on a first surface of the keypad;

a light-emitting device;

circuitry supporting the light-emitting device, and

a bezel formed of electrically-conductive material;

wherein the bezel receives or grounds electrostatic discharges (ESD) to divert the ESD away from the light-emitting device and the circuitry supporting the light-emitting device; and

wherein the bezel further shields the light emitting device and the circuitry supporting the light-emitting device from direct ESD strikes.

18. A lock assembly for securing a container having an interior region, the lock assembly including:

a keypad having a plurality of buttons on a first surface of the keypad;

a L.E.D. positioned on a second surface of the keypad, the first surface being opposite the second surface and including a transparent portion, the light from the L.E.D. being transmitted through the transparent portion;

a bezel surrounding at least a portion of the keypad and having a circumference, and further including a protruding portion having a circumferential length which is less than the circumference of the bezel, the protruding portion extending outward from the keypad and further including a bottom side, the protruding portion and the keypad defining a gap aligned with the transparent portion; and

a reflective surface positioned on the bottom side of the protruding portion and having a circumferential length not greater than the circumferential length of the protruding portion;

wherein the L.E.D. is positioned behind the protruding portion; and

wherein the L.E.D., transparent portion, protruding portion and reflective surface are configured to cooperate to reflect light from the light-emitting device to illuminate the plurality of buttons without requiring either that the keypad include an ultraviolet light reactive portion, or that the L.E.D. be an ultraviolet light source.
