Engine boot lid jammed

[lisacarney68!!!!]

Engine boot lid jammed! I replaced the engine boot key lock and lined up the bracket underneath as it seemed loose. Now its jammed shut and I cannot open the engine area which is clearly a problem. I wonder if anyone has any ideas on how to free it as I have hit it with a rubber mallet and its just not opening at all, key wont turn so dont know if its locked or not but clearly its caught on inside on catch and wont release

What vehicle is it?
Isn't an engine boot lid a bonnet.
