at least one slot extending from at least one of the edges to at least the center of the front surface,

wherein the electronic key reader is configured to read an electronic device.

2. The key reader of claim 1, wherein the protective metal housing member has the form of a plate.

3. The key reader of claim 1, wherein the at least one slot comprises an open end and one end that extends beyond a median line connecting sides which are adjacent to a side that includes the open end.

4. The key reader of claim 1, wherein the at least one slot comprises an open end that is arranged at one of the edges.

5. The key reader of claim 1, wherein the front surface is four-sided and wherein the at least one slot opens out at the at least one of the edges.

6. The key reader of claim 1, wherein the front surface is polygonal and wherein the at least one slot opens out at the at least one of the edges.

7. The key reader of claim 1, further comprising an antenna loop.

8. The key reader of claim 1, further comprising an antenna loop, wherein the at least one slot traverses the antenna loop.

9. The key reader of claim 1, further comprising openings arranged on the protective metal housing member.

10. The key reader of claim 1, wherein the at least one slot comprises a first slot and a second slot, the first slot extending from one edge and the second slot extending from a different edge.

11. The key reader of claim 1, further comprising a plurality of lateral surfaces.

12. The key reader of claim 1, wherein the at least one slot extends into at least one of the plurality of lateral surfaces.

13. Electronic key reader comprising:

a protective metal plate comprising a front surface, a center region, and edges;

the protective metal plate comprising at least one slot extending from at least one of the edges to the center region,

wherein the electronic key reader is configured to read an electronic device.

14. The key reader of claim 13, wherein the at least one slot comprises an open end that is arranged at one of the edges.

15. The key reader of claim 13, wherein the protective metal plate is four-sided and wherein the at least one slot opens out at the at least one of the edges.
