[0042] The integral molding design of the spacer sleeve 36, the flexible push sleeve 37 and the sealing strip 39 can reduce the number of parts during assembly, reduce assembly procedures and difficulty, and improve assembly efficiency.

[0043] Furthermore, such as Figure 5As shown, the button assembly includes a button groove 31 located in the front side of the front cover 11. Several independent button plates 32 are arranged vertically in the button groove 31. Each button plate 32 is directly opposite to each through hole 24. A protrusion 33 is integrally formed on the rear side of the button plate 32 and inserted into the corresponding through hole 24. The protrusion 33 presses against the flexible push sleeve 37.

[0044] When the keypad 32 is pressed, the protrusion 33 on the keypad 32 will press the corresponding tactile switch in the circuit board 23 through the flexible pressing sleeve 37, and complete the triggering of the corresponding function. The principle of the easy-to-maintain car key communicating with the car is a conventional setting in the prior art and will not be described in detail here.

[0045] In addition, in order to install the button plate 32 in the button slot 31, the rear side of the button plate 32 is provided with first buckles 34 distributed on both sides of the protrusion 33, and the bottom surface of the button slot 31 is provided with a first slot 35 for cooperating with the first buckles 34.

[0046] When the button panel 32 is damaged, the operator can detach the front cover 11 from the intermediate seat 13, push the damaged single button panel 32 out of the button slot 31, and replace it.

[0047] The specific connection method of the front cover 11, the rear cover 12 and the intermediate seat 13 is as follows: Figure 8 As shown, the rear side of the front cover 11 is provided with a front cover groove 41 for accommodating part of the intermediate seat 13.

The second fastening assembly includes a plurality of third buckles 52 disposed on the edge of the rear cover groove 51. The intermediate seat 13 is provided with a third slot 53 adapted to the third buckles 52.

[0049] Additionally, a key slot 61 is provided on the side of the middle seat 13 and the front cover 11 facing each other. A key piece 62 is rotatably connected in the key slot 61. When the key piece 62 is fully retracted, it abuts against the side wall of the key slot 61. The front cover 11 is provided with a press-to-unlock button 63 for pressing to release the key piece 62 from its retracted state. When the press-to-unlock button 63 is pressed and triggered, the key piece 62 will pop out under the action of a torsion spring to facilitate key unlocking. This structure is a conventional design in the prior art and will not be described in detail.

[0050] In comparison, the button battery needs to be replaced more frequently than the keypad 32. Therefore, placing the key slot 61 between the middle seat 13 and the front cover 11 will further reduce the difficulty of maintenance.
