Types of Patio Door Locks

Patio doors come in various styles, such as sliding doors and hinged doors, each with its unique set of security needs. To cater to these needs, there is a wide range of patio door locks available, designed to fit different door types and enhance the security of your home. Whether you're looking for a simple yet effective lock or a high-tech solution, this guide will help you make an informed choice.

Before diving into the specifics of the best patio door locks, it's essential to understand the two main types of patio doors and the locks associated with them:

1. Sliding Patio Door Locks

Sliding patio doors are often preferred for their space-saving design and unobstructed views. However, they can be more susceptible to break-ins if not properly secured. Sliding patio door locks typically include:

Sliding Bolt Locks:

 These are surface-mounted locks that engage with a bolt that fits into a strike plate. They are easy to install and provide a basic level of security.

Charley Bars:

 Also known as sliding door security bars, these are placed in the door's track to prevent it from being forced open. They are straightforward and effective.

Keyed Patio Door Locks:

 These locks are operated with a key and offer higher security levels. They often include a secondary foot lock for added protection.

2. Hinged Patio Door Locks

Hinged patio doors, like French doors, are known for their classic and elegant appearance. Securing them typically involves:


 Hinged patio doors can be equipped with deadbolts, which are secure and reliable. Double-cylinder deadbolts, which require a key to open from both sides, provide additional security.

Multi-Point Locks:

 These locks engage at multiple points along the door's frame, making it much harder to force the door open. They offer excellent security but can be more complex to install.

Handle Locks:

 Some hinged patio doors feature handle locks, which can be combined with deadbolts for added security.

The product doesn’t look that impressive, but it can comfortably withstand 300-400 pounds of shear dynamic. Add two of these locks to each sliding door and window to keep intruders out. Because the item uses adhesive, you have to wait for at least 72 hours before testing the lock.

Factors to Consider When Choosing Patio Door Locks

When selecting the best patio door lock for your home, consider the following factors:

Security Features

Strength: A secure patio door lock should be made of durable materials and designed to withstand forceful entry attempts.

Keyed or Keyless: Decide whether you prefer a keyed lock or a keyless option. Keyless locks often offer convenience but can be less secure if not properly configured.

Bolt Type: For sliding patio doors, choose a lock with a sturdy bolt that engages securely with the strike plate. For hinged doors, consider deadbolts with strong bolts.

Material and Durability

What is the patio lock made of? Don’t let the chrome plating fool you. You don’t need an attractive lock. The best locks have a solid construction with a finish that makes them resistant to corrosion. However, If you think that patio door locks are easy to cut and open, you can search for solid iron sliding door locks. The solid iron body gives the sliding door lock a sturdy construction that will be difficult to break or cut.

Your patio door lock should be made from durable materials that can withstand exposure to the elements. Look for locks with rust-resistant coatings for outdoor doors.

Ease of Installation

Consider your DIY skills and the complexity of installation. Some locks, like surface-mounted sliding bolt locks, are easy to install, while multi-point locks may require professional installation.

Aesthetics and Compatibility

Patio door locks should complement the style of your doors and overall home decor. Consider finishes and designs that match your preferences. Additionally, ensure that the lock you choose is compatible with your specific door type.


What is the purpose of the lock? Some patio locks are designed to prevent children from opening the door, but adults can overcome them with ease. Others are robust enough to keep adults at bay.

You also have locks that prevent intruders from lifting the patio door out of its tracks. You can get a lock that plays one or all three roles. It depends on what you want.


Believe it or not, the best locks are the most visible. If the intruder can see the lock, it may discourage them from attempting to force the patio door open. If your objective is to use the lock as a deterrent, get a massive lock with an intimidating design.

Ease of Use

The best locks are easy to install and use. They fit conveniently. They should make things difficult for the potential intruder. If they frustrate the homeowner as well, they are not worth the trouble.

Installation and Maintenance of Patio Door Locks

Installing Sliding Patio Door Locks

  • Measure and mark the desired height for your sliding bolt or Charley bar.
  • Install the lock according to the manufacturer's instructions.
  • Test the lock to ensure it engages securely with the strike plate.

Installing Hinged Patio Door Locks

  • Install deadbolts or multi-point locks according to the manufacturer's guidelines. Multi-point locks can be more complex and may require professional installation.
  • Make sure the lock operates smoothly without any obstructions or jams.

Some Useful Maintenance Tips of Patio Door Locks

  • Periodically clean and lubricate your locks to prevent dust and debris buildup.
  • Test your locks regularly to ensure they are in proper working condition.
  • Check for loose screws or any signs of wear, and address issues promptly.

Enhancing Patio Door Security

While choosing the best patio door lock is essential, additional security measures can further protect your home. Consider the following:

Security Films: Applying security films to your patio door's glass can reinforce it against impact.

Window Bars or Grilles: Adding window bars or grilles can deter intruders from attempting a break-in.

Door Sensors: Integrating door sensors with your home security system can alert you to any unauthorized entry.

Outdoor Lighting: Well-placed outdoor lighting can deter potential intruders.

For those seeking a high-tech solution, consider smart locks that can be controlled and monitored remotely through a smartphone app. These locks often provide advanced security features, such as activity logs and remote access control.


Securing your patio door is not only about safeguarding your home but also enhancing your peace of mind. The best patio door locks offer a balance between security, convenience, and aesthetics, ensuring that your outdoor gateway remains both stylish and secure.

Whether you choose a simple but effective sliding bolt lock, a high-security multi-point lock for hinged doors, or a modern smart lock, the right choice will provide you with the security and confidence you need to fully enjoy your outdoor space. So, go ahead and invest in the best patio door lock that suits your needs and style, and let the fresh air and natural light into your home with peace of mind.
