Changing a door lock is a straightforward process, but there are a few tips and tricks to ensure your new front door lock works smoothly for years to come. We've put together a step-by-step guide for changing your door lock, complete with all the tools and materials you'll need to get the job done right. If ever unsure, always reach out a locksmith for help!
**Selecting Your New Door Lock**
When you're in the market for a replacement lock, make sure it matches the specifications of your current lock. If you have a custom-made door, a standard deadbolt lock may not be suitable. Most locks are designed for doors ranging from 35 mm to 45 mm thick, some newer doors can reach 60mm thickness. If your door is thicker or thinner, you might require a custom solution.
Moreover, deadbolts/ lever lock have something called a "backset," which is the distance from the center of the hole to the edge of the door. The standard backset is typically either 60 mm or 70 mm. It's crucial to match your door's backset with your new lock. Some locks can be adjusted to fit either backset.
If you can't find replacement locks that match your door's dimensions, rekeying your current lock might be a more effective option.
**Replacing vs. Rekeying**
If you're changing your door locks for aesthetic reasons or switching to an electronic model, replacing the locks is your best choice. However, if you're satisfied with your existing hardware and only want to change the locking mechanism for security or convenience, rekeying might be the way to go.
Many high-quality pin and tumbler locks can be rekeyed using a rekeying kit. These kits are designed for specific lock models and include all the necessary tools and instructions. If you can't find a rekeying kit for your lock, get in touch with your local hardware store or locksmith. While locksmiths often offer to come to your home and perform the rekeying, you can save a substantial amount of money by removing the lock and taking it to the locksmith.
**How to Change a Door Lock**
Follow these steps to replace your existing deadbolt lock and hardware. If you've prepared and purchased the appropriate replacement lock to match your existing lock and door's specifications, the process should be quick and straightforward.
**What You'll Need**
- Measuring tape
- Screwdrivers or a drill with screwdriver bits
- Replacement deadbolt kit
- Chisel
- Hammer
- Pencil
**Step 1: Remove Existing Lock**
Start by removing the screws on the interior side of the lock, then slide both the interior and exterior sides out of the door.
**Step 2: Remove Deadbolt and Faceplate**
Take out the two screws holding the faceplate to the edge of the door, and pull the plate and the deadbolt from the door. If it's stubborn, use a flat-head screwdriver to gently pry it away.
**Step 3: Install New Deadbolt and Faceplate**
Slide the new deadbolt and faceplate into place. If the new faceplate doesn't fit the old one's slot, hold the new one in position and trace around it with a pencil. Use a chisel to carefully remove the excess material until the new faceplate fits. Secure the faceplate to the door, taking care not to overtighten the screws.
**Pro Tip:** If you encounter a screw that won't tighten because the hole is too large or the wood fibers are stripped, simply insert a toothpick or a matchstick into the screw hole and break it off flush with the door's surface. Then, tighten the screw as usual.
**Step 4: Install New Lock Hardware**
Slide the exterior lock mechanism (the side with the key) through the deadbolt inside the door. On the interior side, slide the interior mechanism into place. Thread the screws by hand to ensure the two pieces align correctly, and then tighten the screws.
**Step 5: Install New Strike Plates**
Remove the old strike plate from the door jamb and install the new one. If the new plate doesn't fit the old slot, follow the same chiseling procedure as in Step 3.
By following these steps and tips, you'll have your new door lock installed securely and ready to provide peace of mind. Remember, the safety of your home starts at the front door!
