Sometimes, we need a quick fix to secure a door without spending money on a commercial lock.

With a simple homemade trick, you can create an improvised lock using a plastic bottle and some elements that you surely have at home.

It is an easy, effective and perfect technique for when you want to keep a door closed without the need to install anything permanent.

Here’s how to make this ingenious homemade lock that surprised all the neighbors.

Materials

• 1 plastic bottle with long spout
• 1 cutter or scissors
• 1 nail and a heat source (can be a candle or lighter)
• 1 sturdy thread (can be nylon thread or a tanza)
• 1 hot air gun (or failing that, a powerful hair dryer)
• 1 nail or screw in the wall or door frame

Procedure

1. Cut the bottle: Using a box cutter or scissors, cut off the top of the bottle, including the spout and cap. It is important that the cut part is at least 5 cm from the base of the beak to ensure a good fit.
2. Prepare the lid: Heat a nail with a candle or lighter and use it to drill two holes in the bottle cap. These holes will serve to pass the thread that will help hold the lock.
3. Thread through: Cut a piece of sturdy yarn and thread it through the two holes in the lid. Make sure to tie a firm knot so that it doesn’t come loose with use.
4. Place on the doorknob: Insert the spout of the bottle into the door handle, making sure it fits snugly.
5. Heat Tighten: Use a heat gun or a powerful hair dryer to heat the plastic. This will cause the bottle to shrink and adhere well to the doorknob, creating a firm grip.
6. Fasten with the thread: Using the thread you threaded through the lid, tie it to a nail or screw attached to the wall or door frame. This will prevent the door from opening, functioning as a makeshift lock.

Councils

Use a sturdy bottle:

For best results, choose a hard plastic bottle, such as 500ml or 1 liter soda, as they will shrink better when heat is applied.

Alternative without heat gun

If you don’t have a heat gun, you can use hot water to soften the plastic and then press it against the latch until it takes the desired shape.

For different types of doors

This trick works best on lightweight doors, such as indoor doors or closets. For heavier doors, make sure the thread is securely fastened to a firm nail.

With this simple homemade trick, you can improvise a door lock without spending money and using recycled materials.

It is a practical solution, easy to make and very useful for those times when you need to secure a door quickly.
