Door blocked: SOS my lock no longer responds

It’s unfortunate, but it can happen. Locks can get jammed which may cause a blocked door, and you can possibly get stuck inside your own home. Or perhaps, outside. Panicking isn’t an option, but you can’t afford to get stuck with a jammed door for long. Which is why it’s important to diagnose the problem and find a solution. 

The reasons for the jam could differ, and so will the solution. So if you can save the trouble (and cost) of getting a professional involved, why not give these quick-lock fixes a go?

Problem: Rubble and rust build-up 

Solution: Use WD-40 for blocked door

wd40 for blocked doors

The mechanism inside your lock is rather vulnerable to rust and rubble because of daily usage. The clogs and parts inside slowly collect dirt and moisture that doesn’t quite work in their favor. At this point, what you need is something to get right under all the dust, muck, rubble, and rust, clean it all up and unjam your door. And this is exactly what a lubricant like WD-40 does. 

Step 1:
Spray a generous amount of WD-40 into the keyhole of your jammed lock, and let it sit for a minute or so.

Step 2:
Insert and remove the key, and turn it both ways to work the solution into the lock. Turn the key the right way, and check if it works.

Step 3:
Repeat the process one more time, and you should easily be able to open the lock without a hassle. 

Problem: broken key stuck in the lock

Solution: jigsaw blade/tweezers and WD-40


One of the most common reasons the door won’t open is when the key itself gets stuck and broken inside the lock. Most people try to use the same key somehow, to get the door open. It’s important to understand that this will only damage the lock further. The action plan here is to get the broken key out, to be able to open the door without further damage. Here’s how you can do it:

Step 1
Lubricate the keyhole with something as effective as WD-40, to be able to avoid any damage the broken key may cause while being pulled out.

Step 2
Get a jigsaw blade or suitable tweezers, and try to pry the key out carefully. Be as careful as you can. 

Step 3
Once you have the key out, lubricate the keyhole again anyway. You should be able to open the door with a copy of the key now.

Even if you aren’t able to detect the problem with the lock initially, the first thing to try is lubrication. More often than not, you’ll find that it’s the rubble, dust, and rust that cause the jam. If you think the door lock is broken, and none of the quick fixes mentioned above seem to work, stay calm. One call to the locksmith should be enough. And whether you’re trying to get the lock to turn on your own, or relying on the locksmith, remember, patience is key.
