Sliding Doors Should Lock Smoothly
Patio and sliding glass doors are wonderful for letting in light, but they are often the weakest point of security in a home. The locks are mechanically fragile, and the massive weight of the glass puts immense strain on the bottom rollers. When the rollers wear out, the door drops, the lock misaligns, and the door becomes impossible to secure.
iProtect Locksmith provides comprehensive sliding door lock repair, addressing both the locking hardware and the physical movement of the door itself.
Sliding Door Services
- Lock and Handle Repair: Replacing broken exterior handles, snapped thumb turns, and shattered internal mortise locks.
- Roller and Track Troubleshooting: Adjusting or replacing the wheels under the door so it glides effortlessly with one finger, which naturally realigns the lock.
- Keeper Alignment: Adjusting the strike plate on the door frame so the locking hook catches perfectly every time.
- Security Upgrades: Installing secondary security pins, Charlie bars, and keyed cylinders to ensure burglars cannot simply lift the door off its tracks from the outside.
Fix the Cause, Not Just the Symptom
We never simply screw a new lock onto a broken door. We check the movement and alignment first, because a brand new lock will fail immediately if the door requires immense physical force to slide closed.
Frequently Asked Questions
Why does the lock on my sliding glass door keep missing the hole?
The locking hook (mortise lock) inside the door must line up perfectly with the keeper on the frame. If the door rollers wear out, the door drops, causing the lock to miss the keeper entirely. We fix the rollers and realign the lock.
The latch on my patio door snapped off. Can you replace just the handle?
Yes, sliding door handles and the internal mortise lock mechanisms are usually separate pieces. We can replace a broken handle without needing to replace the entire internal locking mechanism.
How can I make my sliding glass door more secure against break-ins?
Standard sliding door latches are notoriously weak. We highly recommend adding secondary security devices, such as track blockers, security bars, or foot-operated pin locks that drill down into the track.
