Lost remote: will this work?

My Hyundai's in the shop at the moment, and I have a loaner Sonata for the
time being. Problem is, I lost the key and remote. The car rental agency
that handles loaners for my dealership was able to supply me with an extra
key today, but they did not have another remote for the car. I locked the
car the last time with the remote.

So... I know the alarm is going to go off when I try the key in the door.
The guys at the rental agency *think* that if I turn the key in the ignition
right away after it goes off that the car will start and the alarm will go
off. Does anyone know if this will work? I really don't want to bring all of
my neighbors' wrath upon me by triggering a car alarm that I can't turn
off...

Thanks for any help/suggestions!

What year Sonata?

 

2003, I believe. I was able to get a better answer from the dealership
yesterday, though. Apparently, if you use the key (setting off the alarm),
and leave it in the ignition for about 2 minutes (the car will not start
during this time, and the alarm continues to go off), then turn the key off,
the alarm will reset and you will be able to start the car. It worked, but
it does seem to have blown a fuse or two...

 

the alarm will work 30 secondes and that's it.
You will never ear it again.
Unless you enable the alarm (wich mean you found the remote )
