Fixing a Door or Car Lock

Unsticking an auto or home door lock mechanism. Does the key to your car, truck or home refuse to turn or even go into your door lock without sticking? This happens to me every couple of years…… usually when the cold weather starts. On my truck, I spray a good amount of lubricant into the keyhole to free up the stuck mechanism. Then I turn the key several times. This method works great for me. On the shop door lock the key sticks on its way in so to remedy this I spray lubricant directly onto the key and run it in and out of the lock until the key no longer sticks. I hope this works as well for you.
