Open stuck hood latch

Take a flat head and pry yhe latch either in middle to the left or push it down

if the car is push button electric and the battery is down, you will need to connect a jump start and then try, otherwise the cable must have snapped and it doesn work.
or just go to the local yard like Car Wreckers Brisbane https://www.qldcarwreckers.com.au/

get it serviced?
if you dont know what oil leaks are or how serious
then get it serviced now,
stop driving it. or burn up a good (hope) engine.
call a tow truck, is best possible end results.
but
open hood, and turn the oil filter CW to tight.
look for road collision damage under car, first.
google how to tighten a filter, oil, see wix filter page, read.

no prob.,. there you go.

did you ask SUZUKI if there is more than one cable.
some cars have 3 for different body types.
you buy this at suzuki? if not this is common.

(the key is dead? or the remote lever?) why not say>?
i know of only these tricks. (all cars not yours)
1: crawl true rear set , hole,behind seat.
2: if electric latch, hot wire it.
3: if cable latch. find a way to get to cable and yank the casing
hard, while person 2 tries to open the trunk.
4: drill out the key hole, then usiing a screw driver open the trunk.
5: drive to any lock shop smith. and ask em. its trivial.
A; they (smith) have working keys, or can make keys or can pick the lock
or failing all that do #4.

the key is lost?
or the key dont work?
the remote lever dead too?
just a hint here.??????????

because of safety dangers, it is very hard to open with out pulling the latch. you will have to take it to a body shop or dealer to have them fix the latch

need to replace brake light switch or at least test
