The key post is configured to hold one or more keys. The key case further includes a fastener configured to detachably connect the key post and the longitudinal top plate and secure the key post with the longitudinal top plate, and a key pushing liner coupled to the longitudinal bottom plate and configured to push the one or more keys toward the longitudinal top plate. ## Claims ### Claim 1 A keycase comprising: a longitudinal top plate; a longitudinal bottom plate; a flexible connector connecting the longitudinal top plate at a first top end and the longitudinal bottom plate at a first bottom end, wherein the flexible connector is made of a silicon material, wherein the flexible connector comprises male protrusions that engage with corresponding female grooves on the longitudinal top plate and the longitudinal bottom plate to connect the flexible connector with the longitudinal top plate and the longitudinal bottom plate; a top reinforcement plate configured to couple to the flexible connector at a top portion where the flexible connector connects with the longitudinal top plate, the top reinforcement plate being configured to reinforce the strength of the top portion; a bottom reinforcement plate configured to couple to the flexible connector at a bottom portion where the flexible connector connects with the longitudinal bottom plate, the bottom reinforcement plate being configured to reinforce the strength of the bottom portion; a key post coupled to the longitudinal bottom plate and extending from a second bottom end of the longitudinal bottom plate toward a second top end of the longitudinal top plate, wherein the key post is configured to hold one or more keys; a fastener configured to detachably connect the key post and the longitudinal top plate and secure the key post with the longitudinal top plate; and a key pushing liner coupled to the longitudinal bottom plate and configured to push the one or more keys toward the longitudinal top plate. ### Claim 2 (depends on 1) The keycase of claim 1, wherein the male protrusions of the flexible connector are inserted into the corresponding female grooves on the longitudinal top plate and the longitudinal bottom plate and at least one fastener fixedly connects each of the male protrusions of the flexible connector with a corresponding female groove on the longitudinal top plate or the longitudinal bottom plate. ### Claim 3 (depends on 1) The keycase of claim 1, further comprising a pocket clip coupled to an outer surface of the longitudinal bottom plate. ### Claim 4 (depends on 3) The keycase of claim 3, further comprising a spacer coupled between an end portion of the pocket clip and the outer surface of the longitudinal bottom plate. ### Claim 5 (depends on 1) The keycase of claim 1, wherein the key pushing liner comprises a fixed portion and a floating portion, wherein the fixed portion is coupled to an inner surface of the longitudinal bottom plate. ### Claim 6 (depends on 5) The keycase of claim 5, wherein the floating portion of the key pushing liner comprises a first end portion and a second end portion opposite the first end portion, wherein the second end is connected to the fixed portion of the key pushing liner, wherein the floating portion extends from the second end portion towards the key post so that the first end portion of the floating portion is located closer to the key post than the second end portion of the floating portion, and wherein the first end of the floating portion is spaced apart from the longitudinal bottom plate when no pressure is applied to the floating portion of the key pushing liner. ### Claim 7 (depends on 6) The keycase of claim 6, wherein the first end portion of the floating portion is spaced apart from the key post when no pressure is applied to the floating portion of the key pushing liner. ### Claim 8 (depends on 7) The keycase of claim 7, wherein a distance between the first end portion of the floating portion and the key post is in a range of 0.5 mm to 3 mm. ### Claim 9 (depends on 7) The keycase of claim 7, wherein the first end portion of the floating portion comprises a notch. ### Claim 10 (depends on 7) The keycase of claim 7, wherein the first end portion of the floating portion comprises a bent portion. ### Claim 11 (depends on 5) The keycase of claim 5, wherein the floating portion comprises an internal recess. ### Claim 12 (depends on 1) The keycase of claim 1, wherein the key pushing liner is made from a single metal piece. ### Claim 13 (depends on 1) The keycase of claim 1, wherein the longitudinal top plate comprises a concave portion in a side portion of the longitudinal top plate, wherein the concave portion is configured to assist in pushing the one or more keys out. ### Claim 14 (depends on 1) The keycase of claim 1, wherein the fastener comprises a screw. ### Claim 15 A keycase comprising: a longitudinal top plate having a first end portion and a second end portion opposite the first end portion; a longitudinal bottom plate having a first end portion and a second end portion opposite the first end portion; a connector connecting the longitudinal top plate at the second end portion and the longitudinal bottom plate at the second end portion, wherein the connector comprises a first end portion and a second end portion opposite the first end portion, wherein the first end portion of the connector comprises a male protrusion that engages with a corresponding female groove on the second end portion of the longitudinal top plate and is connected to the second end portion of the longitudinal top plate and the second end portion of the connector comprises a male protrusion that engages with a corresponding female groove on the second end portion of the longitudinal bottom plate and is connected to the second end portion of the longitudinal bottom plate; a top reinforcement plate configured to couple to the connector at a top portion where the connector connects with the longitudinal top plate, the top reinforcement plate being configured to reinforce the strength of the top portion; a bottom reinforcement plate configured to couple to the connector at a bottom portion where the connector connects with the longitudinal bottom plate, the bottom reinforcement plate being configured to reinforce the strength of the bottom portion; a key post coupled to the first end portion of the longitudinal bottom plate and extending from the first end portion of the longitudinal bottom plate toward the first end portion of the longitudinal top plate, wherein the key post is configured to hold one or more keys; a fastener configured to detachably connect the key post and the first end portion of the longitudinal top plate and secure the key post with the longitudinal top plate; and a key pushing liner coupled to the longitudinal bottom plate and configured to push the one or more keys toward the longitudinal top plate. ### Claim 16 (depends on 15) The keycase of claim 15, wherein the connector is made of a flexible material. ### Claim 17 (depends on 15) The keycase of claim 15, wherein the key pushing liner comprises a fixed portion and a floating portion, wherein the fixed portion is coupled to an inner surface of the longitudinal bottom plate. ### Claim 18 (depends on 17) The keycase of claim 17, wherein the floating portion of the key pushing liner comprises a first end and a second end opposite the first end, wherein the second end is connected to the fixed portion of the key pushing liner, wherein the floating portion extends from the second end toward the key post so that the first end of the floating portion is located closer to the key post than the second end of the floating portion, and wherein the first end of the floating portion is spaced apart from the longitudinal bottom plate when no pressure is applied to the floating portion of the key pushing liner. ### Claim 19 (depends on 6) The keycase of claim 6, wherein the first end of the floating portion is spaced apart from the key post when no pressure is applied to the floating portion of the key pushing liner.
