How to Open a Jammed Door Lock
No one wants to find themselves dealing with a jammed lock, especially if you are in a rush to leave the house. You might be tempted to try and fix the issue yourself, but this might not be the best option. We would always advise you phone a professional Locksmith if you are unable to lock or unlock your door. However, if the issue isn’t that serious you may be able to deal with it yourself.
Whether your door lock is jammed from the outside or whether your door lock is jammed from the inside, these helpful tips may help encourage your lock to operate as it is intended.
Door lock jammed, key won’t turn?
Lubricate the keyhole. If your lock is jammed, it is worth spraying some lubrication into the lock. This will help loosen any debris that has built up within your lock. Remember not to use standard WD40 within your lock components and to use a graphite powder instead. Find out why not to use WD40 on your locks!
Jammed key in lock?
If your key has become jammed in the lock you need to be very delicate with it so that the key doesn’t snap. As above you can use a lubricant to spray into the lock around the key and very gently wriggle it around to see if you can prise it free.
Jiggling the door handle
Sounds simple and might sound silly, but it’s one of the best ways to open your jammed lock. You can try moving the door handle up and down (try pushing right up if a uPVC door) while pushing or pulling depending on which side of the door you are on. This can get the mechanism back into alignment allowing you to get in or out.
This is a relatively safe method as long as you don’t use too much force. Slamming, kicking or banging your door will cause damage and potentially break it. Try to focus on the handle pull it up, down and side to side while jiggling the door with care.
Using a hair pin
You’ve seen people do it in the movies; get to a locked door, pull a hair pin out of their hair, insert it into the lock, wiggle it around and bingo! The door opens. As much as you could “technically” open a locked door with a hair or bobby pin, it’s very unlikely that you’ll be able to open any with a hair pin, especially if something is broken inside – not to mention you could potentially be doing more damage than good!
Use a credit card
Again, this is something you may have seen in the films, someone using a credit card to open the door. Much like with a bobby pin, in theory this can work. However, it’s more than likely you will end up snapping your credit card before you get the door open. The theory behind this is that if you can get your credit card between the bolt and the keep, you can get it to retract. The credit card method only works on a spring bolted door and is the most effective if your door lock is jammed from the outside.
Why is your door getting jammed?
Faulty installation
This is the most common reason for doors jamming. Doors need to be installed with precision, anything that’s slightly off can mean your door is likely to jam. If your door tends to jam a lot, then it may be worth having a Locksmith come to have a look and possibly realign it.
Shifting foundation
It’s possible that a shifting foundation can be affecting your door. A shifting foundation can move your doors and windows by a small amount, but this is all it takes to mean they don’t work properly. Unfortunately, if this is what is causing your lock to jam, it’s not a simple job to fix. The whole foundation will need to be repaired and your doors and windows refitted to stop them from jamming.
The weather
Factors such a humidity or temperature changes can affect your door lock. Your front door is most prone to this as its exposed directly to the elements. Heat and humidity expand the door, which can cause it to jam. You can remedy this by removing the door and sanding the edges, if you sand too much you may cause a gap and as we previously said, removing the door is no easy task. Modern doors tend to allow for this sort of expanding, so upgrading your front door may stop it from jamming in summer.
Obstructions
This might sound like an obvious one, but debris around your door can cause it to jam. Check for dust and dirt around the hinges and within the lock itself. Cleaning your door and door frame regularly can stop it from becoming jammed, making it a part of your cleaning routine can help the longevity of your door and lock.
Faulty Hinges
Your front door gets used multiple times a day, so is prone to some wear and tear. If the hinges start sagging then your door can jam, as the screws will be loose, and the door can tilt slightly. If you think your door needs its hinge replacing, then call a local Locksmith to come and fix the issue.
Call a local Locksmith
We cannot offer you any advice better than to call a fully trained Locksmith if you have an issue with your door. You can try the methods we have mentioned to try an unstick your door, but they may not work, and you could make the situation worse. you can find a local Locksmith on our find a Locksmith page.
