Surely your god must be stronger than science
I agree with XTXchange it out and start over. And in the future, if your key is giving you trouble, use graphite, which comes in a little tube that you can squeeze right into the lock opening. Don't use WD-40it's oily and will make the lock work a little better for a little while, but it eventually attracts a lot of dirt and stuff that winds up gumming up the lock even worse.
Ask a garage to modifier the bar for you so it will fit your car ,it should be a straight foreword job .
The best firearm is the one that will do what you need when you need to do it. Shotguns are great, but limited in range. Rifles can really reach out and kill at a distance, but are not suitable for birds or other quickly moving targets. Handguns are great close-up, but I wouldn't want one to be the only thing between me and a trained soldier with an automatic rifle. If I were going to war, I'd probably opt for an AK47 and an armored personnel carrier to hide in.
