There’s no denying that you have a strong lock attached when it comes to viewing in from the garden.

This lock features a solid build that feels heavy, but that may prove its sturdy construction. It’s made from 3 mm steel that isn’t easily bent or broken. The white powder-coated finish is durable, withstanding scratches, so it isn’t prone to chipping.

The lock does feature a key design than a press and go system. It includes a padlock and two keys. The padlock doesn’t seem high in quality as the rest of the lock, so it may need replacing.

This Patio security bar is a handle lock that offers you some versatility.

Although it’s made for two horizontal handles, you can adjust the width. This is so that it can fit French doors of various sizes and styles.

Tough & Easy Door Lock

French Patio Door Lock
Our Rating:
4/5

The Tough & Easy French Patio Door Lock is for two horizontal door handles. It fits P, D, and standard grips.

An intruder should be able to notice this lock from the outside. It won’t rigidly stick out inside your home if aesthetics are your concern.

As for how you use it, this lock features a padlock layout. It comes with two keys so that you have an extra to stash or give to family members. If you wish, the design does allow you to change it to another similar-sized padlock or combination lock.

Although the 5 mm steel construction appears well-lasting, the white powder-coated paint may still chip. It’s questionable then how long this lock can hold up.

Understanding The Options Available to Us

Reinforcement

This is working on a solution on the door’s existing lock. It’s buffering up the current lock, and the options presented on this page do that.

It diminishes the intruder’s ability to pick or forcibly enter the premises.

They can be made by manufacturers of the original locks or by third party suppliers that offer a general, all-in-one product.

More often than not, they do not require any specialist locksmith skills and will be plug and play type products.

In this instance, the problem is that the item doesn’t fit around your current door locks or handles, as they have been designed to be used for various brands.

Door Jamming

These are the most popular rear door security enhancements. Made of stainless steel or reinforced plastic, they don’t look pleasing and can hinder if you’re trying to use the space next to the door. They look a bit like a crude solution to something that required a bit of afterthought.

They do the job as required and stop any brute force entry attempts.

They are often portable and easy to carry, so it’s not a problem to use them on alternating doors.

Door Bars

Again, this will prevent the forced entry that you sometimes see in commercial properties. The door security bar is placed along the middle of the door, horizontally.

This type of product won’t be suitable if you have lots of glass panels on the door. They can be a bit heavier than jammers, but the benefit is that they are adjustable to fit many different door types.

How We Decided On Our Winner

French doors are a great way to add more light to your home and provide a chic touch to your home’s layout. With the right lock, you don’t have to sacrifice safety for style.

FAQ and Buying Guide

They may not be pretty to look at, but they’re not unbreakable for intruders.

You can take steps to make French doors safer. This ranges from ensuring the glass installed is reliable, checking that the hinges can have access from inside the house.

These security measures aren’t designed the same, and they should measure up to certain quality factors. This way, you might have an easier time deciding on which one is worth purchasing.

Type of Lock

Locks come in a couple of styles. Some need you to push and click, requiring no keys or any code input to unlock and remove it.

Others resemble more of a lock bar and feature a hook where you place a padlock that opens with an included key.

What works best for your door may be more of a personal preference as both types can do the job.

Visibility

Potential intruders need a visible deterrent to make them second guess themselves. When it comes to a French door security bar, they’re usually large enough to be seen from the outside. It may be an ideal way to alert burglars that your home may not be worth trying to break in to.

Durable Construction

When it comes to build quality, you want it to withstand frequent use and tampering. Consider locks made from high-quality plastics and metals as well as tamper-resistant spindles. These types of spindles can’t be removed from the outside once you fit them on.

Consider locks that have a powder-coated finish. It can help with the lock’s aesthetics because you’ll be looking at it more than intruders (hopefully!). It’s important the surface can hold up over time without chipping or wearing down.

Ease of Use

Nobody wants to struggle to attach a lock. Although these types of doors may seem difficult to work with, there are locks that you can fit with relative ease. You might be able to slip the lock on in mere seconds without using any tools.
