This review is from: Graphite Lock Lubricant
We had been having trouble opening the front door for some time, to the point where I thought we would need to change the lock. A friend suggested trying this. I wasn't confident but it was cheap and if it did the job I would save quite a bit of money. Result: the lock works beautifully. A great product.
