Frequently Asked Questions
My sliding door won't lock — what's wrong?
Common causes include a broken latch, worn locking mechanism, or misaligned door on the track. Our technician will diagnose and fix the issue on-site.
Can you replace just the lock on a sliding door?
Yes. We replace sliding door lock cylinders, latches, and handles without replacing the entire door system.
How do I make my sliding door more secure?
Beyond the standard lock, we can install a secondary lock, foot bolt, security bar, or anti-lift device for added protection.
Do you work on sliding patio doors too?
Yes – sliding patio doors are similar in mechanism. See our Patio Door Lock Replacement page for more details.
