Safety First: How to Lock a Door Without a Lock

There are lots of situations when using a key to lock your door is either not possible or not enough. Maybe the door doesn’t have a lock, or you just need some extra security. Perhaps you don’t want your siblings or roommates barging in whenever they feel like it. Whatever the reason, if you need to learn how to lock a door without a lock, you’ve come to the right place.

There are many affordable ways to lock your door without a key. Most of the options on the list require you to spend some money, but where safety is concerned, you probably won’t mind. However, if you aren’t in a position to buy any of these, don’t worry — there are some DIY options listed below, as well.

How to Lock a Door Without a Lock: 7 Easy Options

1. Using a Door Stopper/Wedge

One of the cheapest and most common ways to keep a door shut is by using a door stopper. If you put it under a closed door and make sure it’s sturdy, it can lock the door without the need for a key. But, you should always test it to make sure it works.

Also, keep in mind that this is not the best option for keeping your door shut. It most likely won’t withstand brute force and kick-ins. What’s more, it only works if the wedge is made of rubber or some other kind of non-slippery material.

Although it’s not perfect, this is a cheap and simple method. The rubber door stoppers cost around $10 on Amazon, and you may even find a cheaper version online. So, if you’re wondering how to lock a door without a lock, and you don’t want to spend a lot of money, consider this method.

2. Installing a Door Lever Lock

If your door opens with a handle that you need to push down rather than twist, then this is something you should consider. It works by blocking the door handle from being pushed down, so the door can’t be opened.

It’s mainly used for child-proofing, so it may not withstand much strong force. Still, it is one of the cheaper options on our list. The average price range is from $10‒16, but there are also some better quality options that are more expensive.

3. Using a Door Latch

Door latches have been in use for a long time. They keep the door closed and are accessible from only one side. Also, they are fairly easy to install, and not too expensive. Door latches vary in size and durability, so consider a heavy-duty one if you want something that will pass the high-force test.

As far as the price range goes, it’s between $5 for the cheapest one and $60 for the heavy-duty one.

4. Having a Portable Security Lock

Another safety measure that is becoming increasingly popular is a portable security lock. It’s a small and easy-to-use device that requires no actual installation. You can use it on a door that doesn’t have a built-in lock system or on a door that already has a lock as an additional layer of security. Due to its small size, it can fit into your bag or purse for whenever you might need it.

One of the most popular brands is Addalock. It costs about $15, which is quite affordable.

5. Using a Door Security Bar/Door Jammer

Similar to the door stopper, a door security bar acts as a barricade. It’s usually made out of heavy-duty steel and has a rubber foot that keeps it in place.

The great thing about this method is that it doesn’t require any sort of installation. You just place the upper part under the doorknob and then adjust the height of the bar to fit the door.

The rubber foot uses the power of friction to keep the door closed if someone tries to open it. Security bars are also quite easy to remove and store in a closet or storage room when you don’t need them anymore.

However, while it may be one of the easiest ways to barricade your door, it’s definitely not the cheapest. The prices can vary from $20 to $110.

6. Installing a Floor Lock/Barricade

The best way to reinforce your door is to install a durable floor lock that can withstand a great deal of force. Floor locks consist of two parts: the baseplate and the barricade. These provide a reliable form of protection — in fact, chances are that the door will break before the lock.

The floor lock works on both single and double doors. When you want to use it, simply slide the barricade into the baseplate attached to the floor.

Most of the locks available on the market only work on inward opening doors, but you can find a few models for outward opening doors, as well. However, the floor lock is by far the most expensive option on the list. The price can go from $150 up to $300, but with the level of security it provides, that seems fair.

7. Having a Keyless Door Reinforcement Lock

Another way to upgrade your security is by installing a keyless door reinforcement lock. You can easily use it to lock and unlock the door with a single motion. It does require you to drill into your door frame, but it’s a simple and permanent solution.

Also, it’s not that expensive. The cheapest ones are around $13, and the pricier ones are not more than $26.

The keyless door reinforcement lock can withstand a good amount of force. But keep in mind that your door frame needs to be sturdy enough to support it.

DIY Options on How to Lock a Door Without a Lock

If purchasing any of the tools mentioned above is not an option, but you still want to know how to lock a door without a lock, here are some DIY methods you could try out.

1. Homemade Door Stopper

If you don’t have a door stopper at home, you can easily make one. All you need is a piece of cardboard and 5 minutes of your time.

First, take any piece of cardboard and cut out a strap. It should be roughly 4 to 5 inches long, and at least one inch wide. If you want, you can make it wider. That will provide more surface for friction to hold the door in place.

After you’ve cut it, you should fold it in half to resemble the letter V. Then fold one-third of each of the sides inward. The end result should look something like an arrowhead. Once you’re done, place it under the door and test it a few times.

It’s a good alternative to a commercial door stopper, but it’s not perfect. If you’re worried that it won’t hold, you can add rubber bands around it. This will create more friction when someone tries to open the door, which will make your homemade door stopper hold better.

2. Using a Fork to Lock the Door

It may seem odd, but when you don’t have any other options, just use a fork! If you follow our instructions, it should work similarly to a portable security lock.

First, cut the fork in half and bend about half an inch of the prongs. Then, open the door, take the top part of the fork, and stick the bent prongs in the strike plate. Close the door and slide the handle of the fork in between the middle prongs. Now the door is locked.

Keep in mind that, even though this will keep the door from being pushed open, it will not hold against forceful entries such as kick-ins. But, it is a quick and easy way to lock your door when you have nothing else at your disposal.

3. Making a Barricade out of Furniture

When you want to stop someone from forcefully entering the room, but you don’t have a security bar or a floor lock, making your own barricade out of furniture is another good alternative.

You can simply use a chair and put it under the door handle as a support to stop the door from opening. If you don’t feel like that’s enough, any heavy piece of furniture can act as a barricade. You can even stack multiple heavy items on top of each other.

4. Using a Belt

This method works best on doors that have an automatic door closer. In order to lock the door, you need to tightly bind both arms of the automatic close mechanism with the belt, so that it can’t open.

Another scenario where you may use a belt is if your door has a hook or something similar that is attached either to the door or the wall above. The idea is to tie the handle to the hook. If you can’t push the handle down, then you can’t open the door. This method works with both inward and outward opening doors.

5. Removing the Door Handle From the Outside

If there is no handle on the outside, people can’t open the door. Sounds simple, right? Removing the door handle from the outside works on both inward and outward opening doors. It’s quick and easy, and it’s the only method not involving any special tools or items, except a screwdriver.


Note: Keep in mind that none of these DIY solutions for how to lock a door without a lock provide you with a 100% guarantee that you’ll be safe. They are just a free alternative to the purchase options. And while some may work better than others, if you’re really worried about your safety, you should consider spending some money.
