1. A safe comprising:
- A. a box,B. a lid connected to said box via a hinge,C. two latch assemblies for locking said lid onto said box,D. two latch assembly opening devices respectively connected to the two latch assemblies,E. two electronic circuits each comprising one Nitinol wire each connected to one of the latch assembly opening devices, wherein said two Nitinol wires shorten after receiving said electronic signal causing said latch assembly opening devices to move from their original positions and to open said two latch assemblies to release said lid from said box so that said safe can be opened,F. a user controllable keypad connected to said electronic circuit for allowing a user to transmit an electronic signal to said two Nitinol wires,G. a user controlled key lock, two lock levers, two push rods, two rotatable push plates, two internal spring mechanisms, a key mechanism and a key which when the key is turned to an unlocked position a top portion of the two lock levers are pushed apart by the key mechanism causing the two lock levers to pull the two push rods to push the two rotatable push plates causing the activation of the two internal spring mechanisms to release the two latch assemblies from the lid.

Abstract
A safe. A safe lid is connected to a safe box via a hinge attachment. The safe is locked shut by utilization of a latch assembly. A Nitinol wire is connected to a latch assembly opening device. The latch assembly opening device is connected to the latch assembly. A user can open the safe by inputting the correct pass code into a keypad. An electrical signal is then transferred to the Nitinol wire causing the Nitinol wire to shorten. The shortening of the Nitinol wire causes the latch assembly opening device to open the latch assembly. In a preferred embodiment a key lock is also configured to control the latch assembly opening device and the key lock may be used as another method to open the safe.
