Since most sliding glass doors open onto patios, balconies or backyards, homeowners tend to see them as an entrance to a sanctuary. As a result, many people neglect the security risks associated with faulty or insufficient patio door locks. Investing in quality patio door locks is an inexpensive and simple way to increase the security and safety of any home.

Most standard sliding doors come equipped with a basic up and down switch-type lock. Due to physics, these locks tend to loosen and wear over time. While homeowners are unlikely to notice weakening locks, thieves will. A large number of break-ins occur through sliding doors. When shopping for sliding patio door locks, there are several options to consider.

Aluminium patio door locks that attach at the top of the door are a popular choice. These spring-loaded locks mount easily to the doorframe. When engaged, they prevent the door from opening. An added bonus to this type of lock is that they are installed out of the reach of little hands. An extra measure of security can be gained from keeping people in – that is, little people – when a swimming pool or other dangers in the backyard threaten small escapees. Many models also provide a second locking point, allowing homeowners to leave the door open a few inches for ventilation and airflow.

Patio door locks can also be purchased in floor models that fit into the door rail. Like the locks above, they are mounted behind the sliding panel, preventing the door from opening. Models operated by foot power are available. A simple step down or flick of the toe disengages the lock. No reaching or bending is involved in the operation of these locks. For heightened security, consider a floor-mounted deadbolt. These locks are easy to install and prevent lifting the door from the frame – a common burglary technique.

For the ultimate in patio door security locks, it makes sense to invest in a keyed lock. Similar to the standard deadbolt locks found on traditional doors, these locks operate through a sliding bolt that moves into the door housing when the key is turned. Sturdy and usually equipped with tamper-proof screws, these locks are effortlessly installed and provide serious security. Many models also include additional features to prevent accidental lockouts.

Investing in a quality patio door lock is an inexpensive and easy way for homeowners to achieve added peace of mind.
