A sliding door lifts off its rollers in four seconds, glass intact
Three screws in the top track and one cut dowel in the bottom, plus the lamp timer trick for early dark.

A sliding glass door can be lifted off its rollers and set aside without breaking the glass. The factory latch is a hook, not a lock.
Today’s Skill
Pin the slider, top and bottom
Your patio door has two weaknesses. It slides, and it lifts. Cut a wooden dowel to fit the lower track snug so the panel cannot travel. Then drive three short screws into the top track, heads down, leaving about a quarter inch of clearance. The door still rolls, but nobody can lift the panel off its rollers. Add a keyed pin through both frames for a third layer.
On The Radar
Dark arrives before you do
Sunset slides earlier every day, and by late September your house sits dark an hour or two before anyone gets home. Empty and unlit reads as easy. Put two interior lamps on cheap outlet timers, set for different rooms and different hours. Cut back any shrub that hides a door or a ground floor window. Tell one neighbor your normal arrival time.
The Drill
The lift test, tonight
After dark tonight, go outside and grab your slider by the handle. Lift straight up, hard. If the panel rises more than a quarter inch, it can come out. Measure the lower track, cut a dowel or a length of closet rod to fit, and set it in. Drive the top track screws. Then walk the outside of the house and note every window a person could reach from the ground.
Ready beats lucky.
