Our local locksmiths in SW London see lots of causes for seized, jammed or stuck door latches which prevent doors from opening or closing properly.

It’s not always evident what the cause is, but our technicians have years of experience and can find the cause quickly and offer the best solution, whether it’s the latch, nightlatch or the lock – here we can include all the well-known security brands such as Banham, ABS, Dorma kaba, Mul-t-lock, Yale and so on.

Here are some of the most common reasons why a door latch becomes stuck:

The strike plate is not aligned

The latch springs out when it touches the latch and locks into place, so it can’t be retracted.

However, if the door or frame has caused it to become out of alignment, then the latch might be stuck fast in a position it shouldn’t be in.

Trying to pull the latch back can damage the internal mechanism, and the solution lies in how the door is positioned.

Our locksmiths in SW London will check carefully where the latch is fitting into the strike plate to discern the issue.

Sometimes this is caused by loose screws on the hinges, which cause the door to sag.

Another cause is repeatedly slamming the door, which has caused the strike plate to become bent, meaning when the latch is fully retracted, there is still a piece of metal preventing it from opening again.

Dirt or debris clogging the latch mechanism

The simplest cause of people seeking professional help when they don’t need to is a dirty latch mechanism. 

Over time, dirt and dust can get inside the internal mechanism and build up on the parts of the latch. If the lock is old, then it’s likely that pieces of rust might be accumulating inside and need to be cleaned out.

We can provide this ongoing maintenance for you with frequent checkups once a year, as if you try to open the latch mechanism to clean it yourself, something could fall out, and you don’t know where to replace it.

Other types of debris might be freshly chiselled wood from inside the strike plate that hasn’t been smoothed out, or even small objects like a screw stuck inside the door frame.

If you’ve recently painted, then the extra millimetre of paint around the latch could prevent it from closing properly.

Worn-out latch components

There aren’t many parts to a latch, but after years of repeated use, they can begin to wear out or get jammed. When you press down the handle, the bolt might not pull back the spring that operates the latch, or push it out again when released.

We carry a wide range of replacement parts in our mobile locksmith vans, so we can replace any issue on the first visit. We’ll open the lock to examine all parts of the latch, and we’ve seen issues as diverse as rounded off bolts, broken springs and corrosion.

Latches are usually easy to fix, depending on the type of door and lock, and if there is any rust that has built up on a worn-out component, we’ll simply replace it like-for-like.

Sometimes, the issue might not be the latch itself, but the cylinder, handle or spindle. If a spindle is not the characteristic square shape, it won’t be able to push and pull the latch as it should. You can check this yourself with a screwdriver by removing the two screws that hold it in place.

Expansion and contraction due to temperature changes

Latches are made of metal, which can expand in hot weather and do the opposite in cold weather. If the latch is no longer aligned with the strike plate, it won’t slide into the hole properly, no matter how much you adjust the knob or handle with a screwdriver.

However, most of the time, the swelling issue is not to do with the latch itself, but with the door or the frame. A humid atmosphere causes a wooden door to swell in the frame so that it doesn’t fit into the frame. The whole door will be out of alignment, so naturally, the latch and strike plate aren’t lining up either.

We can fix this issue by using a screwdriver to reset the door hinges accordingly and pull the door into the right position within the frame. It could also be caused by the house settling over time, so the frame and door might both need to be fixed and adjusted.

Condensation can also cause rusting within the latch itself, so ensure it is properly lubricated with a silicone-based lubricant.

If the latch is stuck inside the strike plate and won’t move, then you can try the credit card trick. This credit card method is what you see in movies, where you press a thin piece of plastic on top of the latch and cause it to retract just enough so you can get the door open. Be careful that you don’t damage your bank card or other important piece of ID.

When the latch is stuck or jammed inside the latch, you can tap it with the end of a screwdriver to try to release it. If the issue is the strike plate bent out of shape, needle-nose pliers can straighten it out without damaging the door frame or the latch itself.

How to loosen a stiff latch without damage

You shouldn’t put too much pressure on the knob or handle when trying to release the latch, but you can wiggle it around to loosen the spindle in the hole. For door handles, pull gently up and down as it might release the latch.

Be aware that if you do release the latch but it won’t retract when you pull the handle or twist the knob, don’t close the door, as it will get jammed in the strike plate hole.

It might be something as simple as adding some graphite powder to loosen it up if the latch mechanism has seized, but if a part has broken inside the lock, we’ll need to take it apart to fix it. You should never apply too much pressure to the doorknob or wipe the area with water or oil-based lubricants, but instead try pressing the latch in.

If there is resistance, then something has likely snapped inside the door latch. When turning the doorknob or handle, watch to see if the latch moves at all.

Also, if it doesn’t grab it even slightly, the spring mechanism that locks and unlocks the latch is not working and needs to be replaced.

If you’re dealing with a security issue caused by a latch that has stuck, you can always contact our service 24/7 to get the help you need. We can provide advice over the phone as well as attend your property in person, whether it’s residential or commercial, to deal with the issue.

We will inspect the latch mechanism when we arrive, and if we need more info about why it’s sticking, we can take it apart with a screwdriver and check inside. If the latch has broken on a new lock, then it can mean you’re locked out of your home if it’s stuck in the closed position.

In these scenarios, we can gain access to the property using non-destructive techniques, so we don’t damage the latch, lock, or door. When the latch is locked in the open position, you should still be able to lock the door, but it does pose a security risk as it can be jimmied open with a thin prybar.

We work fast and don’t charge high call-out fees like some of our competitors in London do, so you can always be sure of the best level of service for a price you’re happy with.
