Common Door Lock Problems and How to Fix Them
Here’s a run-down of the most common types of door lock problems.
Frozen Locks
A frozen lock can be a common nuisance, especially in colder climates where moisture can seep into the new lock and temperatures plummet. Attempting to resolve this issue yourself can lead to further damage, so it’s essential to proceed cautiously.
Avoid forcing the key into a frozen lock, which could result in a broken key. While a lock de-icer can be helpful during winter, it’s not always the best solution. These de-icers typically contain alcohol and lubricants designed to combat moisture and dirt buildup.
Another trick is applying graphite into the keyhole, which can help unfreeze and clean dirty locks. However, if these methods seem too daunting, it’s advisable to seek assistance from a local locksmith.
Here are a few quick fixes for you to try: Using a hairdryer to melt the ice, or heating the key in hot water or with your car’s heating system can help thaw the latch. Commercial aerosol lock de-icers are also available for purchase.
However, contact a locksmith if you prefer to avoid potential damage to your front door. Their expertise can provide the best solutions for dealing with frozen locks without harming your locks or keys.
Loose Door Lock
A loose door lock is pretty common, especially in doors with lever-style knobs. These locks can get loose from being used often, especially in busy places like bathrooms and bedrooms.
Things like kids pulling on the door knob or people turning it too much can make it worse. Sometimes, the locking mechanism inside can slip, which stops the lock from working right.
Fixing a loose door isn’t too hard. First, you’ll need to take off the part of the door knob. You’ll need a flathead screwdriver for this. Be careful not to mess up the plate behind it, or you might ruin the lock.
If you can’t fix it and end up damaging it, you might need help from a locksmith. Once you’ve got your screws out, the knob or handle will be loose. Next, clean out the part where the key goes. Sometimes, debris and dirt can get stuck there, so you’ll need to clean it out.
If you can’t get it out, use some oil. To tighten up the loose lock, line up the handles on both sides of the door and either tape the knob in place or have someone hold it for you.
Once they’re lined up, tighten up the screws until they’re snug, and replace any that are broken or don’t work right. This should fix the issue and make your locking mechanism work properly again.
Broken Lock
If you’re stuck with a broken door lock, your best bet is to get help from a locksmith. As a last resort, you could try taking the latch apart to check for any jams or broken parts that need fixing.
However, dealing with lock mechanics can be tricky, so it’s usually safer to let a professional handle it.
Jammed Lock
When bolts or door locks get jammed, it’s typically due to dirt accumulation or lack of lubrication. Exterior doors, in particular, are susceptible to exposure to the elements, leading to the collection of particles that hinder key insertion or turning for unlocking.
For jammed locks, use graphite spray or silicone-based lubricants to unlock the door by applying the product and turning the key several times. Avoid oil-based lubricants like WD-40, as they can increase clogging issues in the long run.
Try applying a dry Teflon lube or powdered graphite to the keyhole for a quick fix to alleviate the jamming. Exterior doors may require a commercial lock cleaner sprayed into the keyhole to dissolve debris. Compressed air can help dislodge dirt within deadbolts and keyed locks.
While WD-40 and powdered graphite may offer a quick fix for jammed locks, it’s important to address underlying issues to prevent further problems with your lock mechanism.
Misalignment
Heat and humidity can cause doors and their frames to warp, leading to the misalignment of bolts and strike plates. Rough handling of doors, like pulling or swinging door hinges with force, can also knock the deadbolt and strike plate out of alignment.
To fix this, you can unscrew the mechanism to adjust it, then realign the deadbolt and strike plate and tighten the screws. If the problem persists, you may need to adjust the door by loosening the door hinges and aligning it parallel to the door frame.
Calling a professional locksmith for repair or replacement may be necessary if these steps don’t work.
Misaligned door locks pose a security risk, as they can make it easier for intruders to bypass the door.
Key Broke in Lock
If a key breaks inside your door’s lock, avoid using the broken piece to lock or unlock the door further. This mostly happens with a poorly cut key.
If enough of the broken key sticks out, you can use needle-nose pliers to pull it out carefully. Make sure to pull straight out, not at an angle, to avoid breaking the key further.
Another handy tool for removing a broken key is a paperclip. Bend the clip so the tip points downward and insert it into the keyhole above the broken key piece. Gently press it into the keyway and gradually pull it out.
Dealing with a broken key can be frustrating, but staying calm is crucial to avoid damaging the door further. Panicking and using force on the key to take it out can damage the latch.
Entire Cylinder Turns
If the entire door lock cylinder turns when you insert the key, it signifies a bigger problem.
This could indicate a loose or broken screw. Start by checking if the set screw is properly tightened.
However, fixing this latch issue isn’t always straightforward due to the variety of door locks available. Some of the most effective exterior door locks combine a mortise key lock and deadbolt, which is common in commercial door locks.
To address this problem, you’ll need to locate and access the screws holding the cylinder in position within the lock. This might involve removing the faceplate or even part of the lock from the door. The location of these screws can vary, making it a bit tricky.
Mortise locks typically have set screws hidden behind the faceplate, which you can access after removing it. Once you find the screws, tighten them as much as possible and put the faceplate back on. If the screws are rusted or broken, replace them before reattaching the faceplate.
After installing everything, test your latch to ensure the cylinder functions properly again. This should resolve the issue and restore functionality of your door lock.
Door Won’t Close Properly
When your door won’t shut completely or the latch mechanism doesn’t function properly, it can make locking it securely difficult.
For the lock to function correctly, there should be proper alignment between the bolt and the strike plate, and the door must fit properly within the frame.
