How sliding doors get forced
Intruders lift the door off its track, force the weak latch, break the glass or exploit loose hardware. The standard hook latch is easily defeated. Knowing the weak points shows which fixes matter.
Track bar or security bar
A bar or a cut broom handle in the bottom track stops the door from sliding open even if the latch is forced. A folding bar costs little and is quick to use. A bar at the top track stops lifting. Use both for good protection.
Secondary locks and bolts
Add a keyed secondary lock, a pin lock through the frame or a surface bolt. Place a second lock near the top and bottom as well as at the handle. Choose stainless hardware that resists drilling.
Anti-lift blocks and rollers
Fit anti-lift blocks in the top track so the door cannot be lifted out. Keep rollers adjusted so the leaf sits low in the track. Poorly adjusted doors are easier to lift. Heavier leaves are harder to remove.
Glass upgrades
Laminated glass holds together when struck and delays entry, and security film on existing glass adds some resistance. Tempered glass shatters into pieces and gives little delay. For high-risk sites, specify laminated glass.
Alarms, sensors and lights
A door contact or glass-break sensor raises an alarm, outside lighting deters intruders and a camera records them. Combine with a locked gate at the balcony level where possible. See door security systems.
Daily habits
Lock the door whenever you leave, close it at night even for short breaks and do not leave keys in locks or near the door. Keep valuables out of sight from the balcony. A good lock is useless if left unlocked.

Prices move with brand, model, size and stock. Use these ranges to judge a quote, then compare the exact model and what is included.
For renters
Use removable fixes: a bar in the track, a clamp-on lock, a pin lock and a sensor with adhesive mounting. Ask the owner before drilling. Fitting should be done by a trained carpenter or fixer, and the frame and wall checked for level before the door is hung. Keep the specification, drawings and finish details in one folder and compare at least two quotes on the same list, because small differences in thickness, core and hardware explain most price gaps. Ask for delivery and fitting dates in writing and inspect each door on arrival before the carpenter leaves.
