5 Possible Reasons For Malfunctioning Of The Triple Lock Security System

When you’re mentioning anything about home security in a shady neighborhood, it’s a must to have a triple lock security.

But just like any other security system, you might find this triple lock security system troubling sometimes.

There are 5 possible reasons that might have caused the malfunctioning of the triple lock security system that you own. Let’s check those out-

1.  Door Material

Wood, composite, and UPVC. These are the most common type of materials that you’ll find to be used for a door.

Wooden and the composite doors are very durable and you’ll rarely find any problem developing in these.

However, if you have a UPVC door, it’s very common for you to suffer. Because UPVC doors dropping are more usual than you think. And that causes misaligning the locking points with the keeps.

It’s mostly the external environment that causes this kind of problem. Because the UPVC doors can expand in the summer as the heat rises up.

The temperature plays a huge role in the expansion and shrinkage of the UPVC doors.

2.  Faulty Lock Cylinder

The most common thing that you’ll encounter with the locks is a faulty lock cylinder.

Most of the time, the movement of the keys inside the lock doesn’t affect the lock and that’s when you know something is wrong.

3.  Key Stuck in the Lock

There are scenarios where the keys generally break in the locks because of too much force applied to them.

Often when you’re about to enter your home and you insert the key in the lock. But you feel that your key is stuck in that lock and you’re not able to move it.

At that exact moment, most people make the mistake of putting in the extra effort of twisting it real hard. And your key will break if it can’t take the pressure still keeping you outside of the house.

4.  Key Fit in the Lock

You’re trying to enter your home one day and the key isn’t really going inside of the lock.

Well, if you have a triple lock security on the door for quite a time, here’s what might have happened.

There’s a chance that the cold weather or debris might have caused a problem with the cylinder of your security system. If that’s not the case, you might have got the wrong key.

5.  Faulty Lock

With time, there’s a high chance that the internal mechanism of your lock is broken. But that’s a rare case if you’re using the triple lock security system.

So, let’s have a look at how you can fix the triple lock security door of your right away-

Step 1: Fix The Alignment Issue

If you’re facing alignment issues with your door, it’s a very natural issue. Rough weather might often cause this issue.

Most of the time the door doesn’t fit and doesn’t lock because of this issue. There’s a simple solution to get your door fixed in seconds.

We’re going to explain the trick simply for you. You’ll notice something like a small button right up the bar of your lock which is known as the deadlatch.

When you press this small button like thing, you’ll notice that the lock bars will come out a bit further.

Just like that, it’s a simple solution that won’t take you any professionals to act on it.

However, if you still feel that the lock is not suitable enough you might need to realign the whole door again.

Step 2: Fix The Cylinder

The lock cylinder is what helps the whole lockset to operate. Any issues with the mechanism of the cylinder might cause the whole lockset to stop working.

In that case, you’ll need to see if you can fix the cylinder. So, open the lock and take the cylinder apart from it.

Then, place the key inside of it and move it to see if the carrier is parallel with the cylinder or not. If it’s parallel, there’s no issue.

However, if not, you’ll need to take the whole cylinder apart and you might find something broken inside the cylinder. Time to change the cylinder then.

Replace with a new cylinder and make sure that you place the new one correctly in position.

Step 3: Clean The Lock

The issue might not be as big as you thought most of the time. Dust and dirt might often pile up with time in the lock.

You can use pressurized air to blow all the dirt and dust that has been piling up inside of it.

But there’s another option in hand for you. You can also use a spray cleaner to clean out the lock. There are a huge number of happy users who will ensure you how great these work.

However, never apply water inside of the lock to clean it. It might cause the lock to attract rust and make it even worse for you.

Step 4: Lubricate The Lock

Lubricants are used to make your lock more smooth. If you have a rusty lock, there are lubricants that you can use to make it operate more smoothly.

It’ll make the mechanical parts inside the lock more active. You’ll feel like you own a new lock when you move your keys inside the lock.

Step 5: Replace The Lock

This is that last option for you if none of the steps above doesn’t seem to work.

It’s very rare for a triple lock security system to break. However, if the mechanism inside the lock breaks somehow, there will be no option left but to change it.

If you can find out any spare part of the lock to replace the broken part only, you can also replace that. But we wouldn’t recommend that as those parts can underperform most of the time.
