Will this work? The door locks on my 72 mustang won't unlock from the outside, and I read somewhere the you can put graphite power into the keyhole (since its a dry lubricant - dust/other particles can prevent lock from turning), turn the key and it should fix it. Anyone ever tried this? I don't wanna ruin my car...
 
I've used graphite in the past- it won't damage your locks.

Also check the condition of your key & make sure it just isn't worn down to the point the ridges on the key doesn't disengage the lock.

If he graphite doesn't do the trick, you will need to take the door panels off & use graphite or white grease and lube up all of the locking components inside the door
 
The lock may and probably is original equipment and the tumbler
may be beyond wear which would make the use of graphite powder
ineffective. In addition, many times the graphite will run down the
door from the cylinder and leave an ugly stain.
Try getting a new key cut for just two or three dollars and see if
that helps a bit.
You may also consider changing out the lock and key. A good
locksmith can set the new tumber to match the old one so you
don't wind up with mixed keys.

Good Luck on your fix....
