Frequently asked questions
How much should an emergency locksmith cost for a mortise lock repair?
There is no single fixed price because several variables shape the final quote: the lock type and brand (a mortise lock case is more involved than a simple cylindrical deadbolt), whether the work requires replacement parts or just a re-key, the time of day the call comes in, and travel distance to your location. What Pro Melville Locksmiths guarantees is that we give you a complete, confirmed price before any work begins — no surprises and no hidden charges added after the job.
Is there a 24-hour locksmith serving Melville, NY and the surrounding area?
Yes. Pro Melville Locksmiths operates 24 hours a day, 365 days a year, including weekends and holidays. Our dispatch team answers every call live at (631) 301-2229, and a trained, insured technician is sent directly to your address — whether that's a residential street in Melville, a commercial building near the Route 110 corridor, or an automotive lockout anywhere in the coverage zone.
How can I get into my house if I am locked out?
Start with the safest, least invasive options first: check whether a trusted neighbor or family member holds a spare key, try any other entry points you have legitimate access to, and look for an unlocked window on the ground floor. If none of those are available, call a professional locksmith. Do not attempt to force or bypass the lock yourself — improvised methods frequently damage the door frame or lock mechanism and can leave your home less secure. Our technicians use damage-free techniques wherever the lock condition allows, and we verify ownership before beginning any lockout service.
Can you handle sliding door lock replacement on the same emergency visit?
Absolutely. Sliding door lock replacement is one of the most frequent calls we receive, and our vans stock a range of sliding door lock sets and multipoint bar mechanisms compatible with common patio and balcony door brands. If your sliding door lock has failed, snapped, or was damaged during an attempted break-in, we can assess and replace it in a single visit — day or night.
What is involved in a door lock installation versus just changing the lock cylinder?
A full door lock installation means fitting an entirely new lockset into the door — cutting or enlarging the bore hole if needed, installing the new lock body, strike plate, and all trim — and is typically done when upgrading security, replacing a damaged mortise lock case, or fitting a new door. Changing just the cylinder (re-keying or swapping the barrel) leaves the existing lock body in place and is faster and less involved. Our technician will assess your door on arrival and recommend the approach that genuinely solves your security problem rather than overselling unnecessary work.
Do you service keypad and smart locks, including reprogramming or code changes?
Yes. We handle the full range of electronic and keypad lock issues: resetting a unit that has locked out its own programming mode, re-enrolling new user codes, replacing a malfunctioning keypad, and installing smart-lock upgrades that integrate a physical cylinder with app-based access. If you're unsure how to change the code on your keypad door lock or the unit is simply unresponsive, our technicians carry the tools and manufacturer-specific procedures to resolve it in one visit — and we test every credential before leaving.
