so when I brought my 1995 Ford f150 I was provided with one key and I didn't know that these cars at two different keys, one for the ignition and one for the doors. I ended up using the truck for a few months without installing new door lock cylinders that finally bit me when we accidentally locked ourselves out of the truck. so I unlocked the truck with a screwdriver and a hammer and I decided now would be the perfect time to install the lock cylinders, and new interior door handles since I didn't have those either, that I've had in my room for about 6 months. this is the process of how I did it and this is also showing just how easy it is.
