Installation is rather simple since the majority of types on the market are flush mount locks. An expert thief may enter your house in a matter of seconds if the only thing securing your patio door (and home) is a key lock, which is often not too difficult to circumvent. From the outside, a key lock performs the same function that a thumb latch does from the inside: it moves the hook into the open position. The best course of action in this situation is to get a key lock set that also includes handles. If your door handle does not allow for the addition of a key cylinder, you will also need to purchase a new door handle.

You'll probably need a keyed lock if you want to secure your sliding patio door from the outside. The handles, which are often made of steel, wood, or plastic, may normally be changed on their own without affecting the mortise lock itself. In terms of construction, a mortise sliding door lock typically has three primary components: handles (both inside and exterior), a thumb latch, and the mortise lock body. As a result, this lock component is almost invisible. A pocket (also known as a mortise) is carved into the width of the door into which a mortise lock's whole body is inserted. There's a considerable probability that your sliding glass door comes with either a pre-built mortise lock or a basic latch. The most popular kind of sliding door lock is the mortise lock. Another issue is that the majority of homeowners are not actually aware of all their lock alternatives. The primary cause of this is because, to put it gently, the built-in locking system that most sliding doors have is quite unreliable and simple to jimmy open. The fact that sliding door types that are made of glass are sometimes the least reliable entrance points of a property without a decent lock on them, is something I as a sales manager am well aware of.
