How to Exchange a Lock – Substitute Present Door Hardware

Most lock products at this time are constructed to be reasonably priced, and by that I imply low cost. So, they may ultimately cease working and since they’re so inexpensive, it is higher to just exchange the lock than to attempt to repair it.

In this part I am going to speak about how to exchange an present door knob or deadbolt. In case you haven’t but purchased your new door hardware, take a take a look at our article on our favorite lock brands and our favourite deadbolts.

How to Remove Door Locks – Present Hardware

Remove Lock ScrewsRemoving the previous lock is pretty simple. You’re going to have a couple of screws in the latch plate. These can be Philips-head screws, they are going to be brief screws, and they’ll come out very easily. In case you don’t have any screws on the latch, no worries. That just means your door lock has a “drive-in” latch. We’ll speak about that in a bit.

The subsequent step is to find and take away the two interior screws. To remove the door knob screws they’ll clearly be seen on both sides of the knob. For deadbolts chances are you’ll not see the screws. Some deadbolts include a snap-on cover that conceals the interior screws. You will want to pop that cover off to get to the screws and to take away the deadbolt lock from the door.

These screws may be fairly lengthy as they’re holding the lock via the width of the door. Once you loosen each screw it is going to be faster to take away them by turning by hand than by the screwdriver.

When removing these screws it’s also useful to hold the lock in place with one hand whereas the other hand holds each bit of the lock together. This can maintain the strain off the screws so you possibly can shortly take away them by hand and it prevents the lock from by accident falling out and damaging any tile that could be put in.

When the screws are out, each side of the lock will simply slide off, leaving solely the latch within the door.

Usually you need to use your fingers within the hole left by the lock to remove the lock’s latch by means of the aspect of the door. In two instances this is probably not potential.

  • If your lock is a drive-in latch it is going to be tight. Drive in latches are held in place by compression on a defend across the latch. This sort of latch may have to be tapped out with a screwdriver and hammer.
  • Or, if the door is previous and it is wedged in tightly, you might also want to tap it out with a screwdriver.

Adjustable BacksetThis is the time to pay attention to the door lock’s latch setting. Doors have two widespread backsets, 2 three/eight and a couple of three/4. The new latch needs to be set to the right one. The prevailing latch should offer you a good concept of which one to use. See whether it is within the “short” setting (2 three/8) or the “long” setting (2 3/four).

The set up process is actually the reverse of removing.

Totally different Latch Varieties

Putting in the new door lock latch.

There are three kinds of latches. Drive-in latches, rounded corner faceplate, and sq. nook faceplate. If what you’re putting in is identical as what you’ve got removed it’s unlikely that something will want to be executed, the brand new latch should go in very easily, however contemplate this stuff if it doesn’t.

  • Square nook latch going into round nook gap – You’ll need to chisel out the previous rounded corners to set up the new sq. corner latch. Degree of talent – straightforward.

  • Spherical nook into previously square corner – It’s going to match however there can be gaps at the rounded corners. They pose no security danger for those who don’t mind them or you possibly can putty over them with filler in the event you do. Degree of talent – None.
  • Sq. or rounded latch plate into a spot that use to have a drive-in latch – This is probably the most troublesome set up as it is going to require chiseling out to make room for the new latch plate. I’d advocate changing present drive in latches with drive latches to avoid this. But if that is undesired or not attainable, you should purchase latch guides. The latch guides will mark for you where you will have to chisel. You hit them with a hammer to reduce an impression within the door and then chisel out inside this impression. Degree of talent – Troublesome. Right here’s our favorite by Kwikset on Amazon.

  • Drive-in latch into either of the opposite two – Additionally unattractive, however with the right lock adjustments, no safety danger. Degree of talent – None.
  • In some instances the new latch plate could also be just a bit greater than the previous one and wish to be chiseled out to accommodate it. Degree of talent – Straightforward.

Installing a drive in latch.

Tapping in a Drive-In Latch
Drive in latches are meant to fit snugly. The most effective technique for set up is to push the latch in as far as you possibly can after which place a piece of flat wood tight up towards the latch. Then tap it with a hammer to end pushing the latch into the door.

Once the latch is in, I like to install the screws after the rest of the lock is put in. It simply give me some wiggle room to make sure that the whole lot goes together simply.

At this level you want to verify to ensure that the center hole in the latch assemble is aligned to the center of the opening within the door. Whether it is off to the left, or off to the fitting, the latch will want to be eliminated and adjusted to the other of its two positions “short” or “long”.

Installing the brand new doorknob or deadbolt.

You’re going to want to just remember to put the lock on the right aspect. Obviously we’re going to want to have the ability to lock the door from the within and unlock from the surface, so simply be cognizant of that when installing the brand new lock.

Begin by putting the outside aspect of the door knob or deadbolt into the opening.

Locksmith Ideas:

  • Keyed Locks – When placing in an exterior lock piece with a key gap, make certain that the pins are on the top aspect of the lock. Whether it is put in the wrong way up, mud and other particles will shortly fill the pin places making the lock troublesome to use. The lock must be installed in order that the minimize aspect of a key, when slid into the opening, is dealing with up.
  • Earlier than putting in ensure to have your local locksmith key your new locks to your present home key by taking the brand new locks to the closest locksmith shop.

Holes & Rods Need to Line Up
The outside aspect of your door lock has two rods with threads in them that the inside aspect will need to line up with for the screws to thread into.
When putting on the interior aspect of the door visible line up the holes in the knob (or deadbolt) with the receiving rods when putting on the door.

There’s also a center piece. For doorknobs it’s the spindle and for deadbolts it’s the tail piece. Should you lined up the screw holes appropriately these items will naturally align and the 2 lock sides should slide proper together.

It’s now time to tighten the screws. Start by merely threading them in by hand.
They need to go simply and it is possible for you to to tell in case you have lined up the receiving posts with the screws by doing it this manner. Be sure that every screw is threading into the receiving posts earlier than tightening all the best way.

IMPORTANT – Checking Your Lock-Set up Security

Locks only work when they are installed appropriately and there are two essential things you should examine for you lock set up to be secure.

Correct Latch Plunger Alignment

Door Latches on Knobs and Deal with Units – Latch Alignment

See that little additional piece of material on that latch? It’s referred to as a deadlocking plunger. Have you learnt what’s it’s for? Nicely, it serves to lock the latch in place so it will possibly’t be moved/slid back into the open position by a credit card or screw driver. It is extremely necessary on your house safety to modify this when installing door knobs.

When the latch is within the out position and the door is closed, the latch must be pushing that plunger into the door. When it pushes the plunger into the door it locks the latch in place so it might’t be pressured open (see video under). If the door or strike are misaligned, or if someone has floor out the latch hole too massive, the plunger won’t be pushed in and the lock with the latch may be very simply bypassed with a credit card or screw driver.

One of many tips locksmiths use to regulate this is to put a little bit of lipstick on the latch plunger. When the door is closed and reopened it is best to see the lipstick on the stick indicating that the plunger has been pushed in when the door was closed.

Deadbolts – Depth of Gap in Door Frame

In case you’ve purchased yourself a good deadbolt you’ve purchased one with at the least a 1” throw. Meaning the bolt will slide out 1” from the door.

If your previous deadbolt didn’t throw out this far, the opening in the door is probably not deep sufficient for the new deadbolt and it will not safe correctly.

When a deadbolt’s bolt doesn’t absolutely prolong outward, it could actually simply be slid back into the door. Burglars just use a knife or other object to place the bolt back into the door and to bypass it (see video under).

When the deadbolt is absolutely extended, it can’t be pushed again into the door because it locks in place.

Check the door when open to see where the thumbturn is positioned when the deadbolt latch is absolutely outward. Then close the door and check once more to ensure that the thumbturn is in the same place.

You have to be in a position to either hear or really feel when the deadbolt absolutely extends. If it does not absolutely prolong, you will want to drill out the opening in the door frame a little deeper till the bolt absolutely extends into it when the door is closed.
