In this video I explain how to replace a door latch. This applies to both exterior and interior doors with barrel latches and for many brands like schlage or quickset. This will help in situations for door latches that won't open, can't close, or have fallen apart. I show you how to disassemble the door handle, swap out color matching parts, and how to reassemble. I hope this video helps you with your door lock or latch. Please let me know if you have any questions!
