The invention relates to a multifunctional elevator key. The multifunctional elevator key comprises a handle (10) and a key head (20), wherein the handle (10) is fixedly arranged at the top of the key head (20), the surface of the handle (10) is provided with a recessed area (101), the recessed area (101) is covered by a cover plate (102), an elevator locking key (103) is arranged in the recessed area (101), the internal portion of the key head (20) is hollow, a metal block (202) is arranged on the internal bottom surface of the key head (20), the metal block (202) is in contact with a battery (203), a lamp holder (204) is overlaid on the battery (203), and an LED (Light Emitting Diode) lamp (205) is embedded in the surface of the lamp holder (204). The structure is simple and the use is convenient. By integrating two keys for an elevator together, the trouble in finding the keys is avoided, the LED lamp in the key head can illuminate the surrounding environment at dark when the elevator is not powered on, convenience is provided for elevator maintenance and the working efficiency is improved.
