I currently live in a city where there's alot of car theft and would like to know what i can do to prevent me car from being stolen

I currenlty own a 2000 honda civic dx and had my insurence acually go up because there's alot of car thefts where i live. Especially for hondas!
I was looking online and never really noticed just how easy it is to steal a honda eapecially the older types like 2000 down.
I learned that you don't even need the same key or the same year! To open my car door. All you need is a key from another honda and with a bit of practice you can open the door like if it was the key for the car to begine with.

What els can i do to keep my car save?

2000 Honda Civic will crank but not start

I have a 2000 Honda Civic. I traded for it, I was actually a previous owner of it and it ran fine back in the day. I wanted it back and found it. It has been sitting in this guys yard for about 2 months. I go to start it up. It starts up just fine… Then it randomly just shuts off and never have been able to start it up again. It cranks and it smells rich in gasoline when you crank it a couple times. I checked the fuses and battery. Any help would be great.
