How to address binding or sticking door lock cylinders and difficulty in inserting and removing keys on Chevrolet Suburban 2500?

Door lock cylinders should be properly lubricated with GM P/N 12346241 or equivalent products while users should avoid using GM P/N 1052949 or WD-40(R) because these penetrating fluids remove the original lubrication leading to minimal material for lubrication. The procedure for warming up frozen lock cylinders in cold weather requires heating the cylinder with a heat gun but the paint on the surface must be protected from damage. Make the door shutter accessible by placing a paper clip there before using compressed air from a blow gun to introduce pressure into the cylinders. You should both keep the shutter door open and work the key into the cylinder multiple times after droplet injections of suggested lubricant so you can wipe off any surplus lubrication from the key.
