Sometimes the standard mortise locks on sliding doors aren’t enough to withstand a home invader. An additional lock can prevent invaders from damaging the lock or taking the door off the track. We picked these sliding glass door locks because they strengthen the common weaknesses found in many patio doors.
With the Toledo lock, about $40, and a few standard tools, your sliding glass door can become a lot tougher than any potential intruder. It’s resistant to bolt cutters and hacksaws so it’s a seriously tough nut to crack. For additional security, it comes with keys to lock and unlock the bolt when you want to use the sliding glass patio door.
