1. A lock comprising:
- a casing;
an indicator movable between a first position and a second position relative to the casing;
a core received in the casing and having a keyhole defined in an end thereof to alternately receive therein a private key and a general key in such a way that either one of the private key and the general key is able to activate the core, wherein the indicator moves from the first position to the second position in response to a status where the general key is inserted into the keyhole of the core;
a latch having a root rotatably received inside the casing and a free end extending from the root; and
a latch seat provided with a receiving recess to receive therein the free end of the latch, wherein the latch seat is exposed to the casing and connected to the core so that when the core is activated, the latch seat is moved in response to the movement of the core to limit or release the free end of the latch, and wherein the latch seat has a compartment defined therein to receive the indicator and a window in communication with the compartment.
