This DIY front door lock replacement will not necessitate the preparation of numerous materials and tools. It is also a low-cost task, with costs ranging from $50 to $100 depending on the type of lock and the number of locks required. Here’s what you’ll require:

  • Phillips and flathead screwdrivers
  • A hammer with a claw
  • A tape measure
  • A drill with no power
  • Drill bits that twist
  • A pair of protective glasses
  • A deadbolt and a new pair of door knobs are all that is required to replace an exterior door in terms of materials.

If you recently bought a new home, you should change the locks on all front doors and make them universal so that you can unlock all doors with a single key.

Purchase a New Exterior Door Lock

Aside from the above-mentioned tools, replacing front door locks necessitates the purchase of a new lock. Although premium options with key codes and advanced mechanisms are available, spending so much money is unnecessary. We understand your desire to secure this exterior door for the sake of the safety of your family. However, you can rest assured that most compatible locks will function properly, especially if properly installed.

Most standard front door locks will cost between $15 and $50 per item. If you are changing multiple locks at once, try to get a full set for between $60 and $200.

It is worth noting that if you want to unlock every front door in the house with a single universal key, the price will be slightly higher as a result of the added convenience. If you’re on a tight budget, we recommend saving money and purchasing separate keys for each lock.

Components of a Door Lock Set

A standard set of exterior door locks includes the following four parts:

  • Dual door knobs: For use on both sides of a door.
  • A door latch is a unit that is attached to your door.
  • A strike plate is a small piece of hardware that attaches to your door frame.
  • Nails/Screws: Your new set should come with nails or screws for driving strike plates. Depending on your setup, it should ideally be 2 to 4 pieces.

Instructions in Steps

Step 1: Remove the old front door lock.

  • The first step is to remove the lock from the exterior door. You can do it before or after purchasing a new lock, but not too soon before the replacement. This helps to avoid leaving your door open for too long.
  • To remove the entire old lock, unscrew the knob on the inside of your door. Then, as you remove their screws from the unit, both door knobs will loosen.
  • Once these knobs are free, you can proceed to remove the latch on the door’s side edge. Use a screwdriver to remove any nails or screws.

Step 2: Install a new exterior door lock.

Keep track of the following steps in our detailed instructions on how to install a front door lock:

  • First, insert your new latch into the hole along the side edge of the door. Check that this piece is pointing in the right direction. Check to see if the tapered side of the device is facing the outside of your door.
  • Set this latch into place. Make sure the part that connects to your door knob is in the center of the open hole in the door.
  • Try to install the new knobs on your front door, then connect them to the latch. In your kit, look for the provided nails or screws. Tighten the latch against the door knobs and the door itself.
  • Secure the screws so that all components are flush with the surface of the exterior door.
  • Use the remaining screws or nails to secure your new strike plate to the door frame. Before beginning this task, you should remove the old plate unit.
  • Your strike plate must be snug against the door latch for the entire system to function properly. If you use the same type of lock as your old unit, no major adjustments are required.

Tips: If you replace your door lock with a new lock type, you should take extra steps in advance to measure the door and find a compatible lock. As a result, if at all possible, use the same lock style.

Step 3: Put your new lock to the test.

  • After you’ve secured the strike plate to your door, it’s time to put it to the test. Open this door several times from the inside and outside of your home. Is it running smoothly for you?
  • Furthermore, the door latch must engage its catch in the strike plate without causing any difficulty in opening or closing the door. The knobs must be secure without being too loose.
  • Remember to dispose of your old key so you don’t confuse it with the newly installed lock. We recommend making several key duplicates for your new lock in case your first key goes missing.
  • In fact, there are door lock kits that include a spare key. You wouldn’t have to call a locksmith if you got locked out of your house by accident.
