In one illustrative embodiment, the lock assembly includes a keypad having a plurality of buttons on a first surface of the keypad, a light-emitting diode, and a bezel surrounding at least a portion of the keypad. The bezel includes a reflective surface positioned to reflect a light from the light-emitting diode, the reflected light illuminating the plurality of buttons. ## Claims ### Claim 1 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; and a bezel surrounding at least a portion of the keypad and including a reflective surface positioned to reflect a light from the light-emitting device, the reflected light illuminating the plurality of buttons. ### Claim 2 (depends on 1) The lock assembly of claim 1, wherein the light-emitting device is positioned on a second surface of the keypad, the first surface being opposite the second surface. ### Claim 3 (depends on 1) The lock assembly of claim 1, wherein the surface further includes a transparent portion, the light from the light-emitting device being transmitted through the transparent portion prior to reflecting off the reflective surface. ### Claim 4 (depends on 3) The lock assembly of claim 3, wherein the bezel includes a protruding portion extending outward from the keypad, the protruding portion and keypad define a gap aligned with the transparent portion, and the reflective surface is positioned on a bottom side of the protruding portion. ### Claim 5 (depends on 4) The lock assembly of claim 4, wherein the LED is positioned behind the protruding portion of the bezel. ### Claim 6 (depends on 1) 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. ### Claim 7 (depends on 6) The lock assembly of claim 6, wherein the light-emitting device is configured to stop emitting the light after a predetermined time period. ### Claim 8 (depends on 6) The lock assembly of claim 6, wherein the bezel includes an indicator providing a tactile indication of the position of the light button. ### Claim 9 (depends on 1) The lock assembly of claim 1, wherein the reflective surface includes a corrugated surface. ### Claim 10 (depends on 1) The lock assembly of claim 1, wherein the light-emitting device is protected from an electrostatic discharge event on the keypad. ### Claim 11 (depends on 1) 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. ### Claim 12 A lock assembly for securing a container having an interior region, the lock assembly including: a keypad having a plurality of buttons; a light-emitting device; and a bezel surrounding at least a portion of the keypad and including a corrugated surface positioned to reflect a light from the light-emitting device, the light reflected from the corrugated surface illuminating the plurality of buttons. ### Claim 13 (depends on 12) The lock assembly of claim 12, wherein the corrugated surface includes a plurality of substantially parallel ridges and furrows. ### Claim 14 (depends on 12) The lock assembly of claim 12, wherein the corrugated surface includes a first end and a second end, the first end being closer to an outer circumference of the bezel and to the keypad than the second end. ### Claim 15 (depends on 12) The lock assembly of claim 12, wherein the bezel includes a protruding portion extending outward from the keypad, the corrugated surface being positioned on a bottom side of the protruding portion. ### Claim 16 (depends on 15) The lock assembly of claim 15, 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. ### Claim 17 (depends on 12) The lock assembly of claim 12, wherein the corrugated surface is chrome-plated. ### Claim 18 (depends on 12) The lock assembly of claim 12, 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. ### Claim 19 (depends on 12) The lock assembly of claim 12, 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. ### Claim 20 A keypad for a lock assembly, the keypad including: a plurality of buttons; a bezel surrounding at least a portion of the plurality of buttons; and means for indirectly illuminating the plurality of buttons. ### Claim 21 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 positioned over the light-emitting device to shield at least one of the light-emitting device and the circuitry from electro static discharge.
