Frequently asked questions
Can you replace just the cylinder in my door knob with lock, or do I need to replace the whole knob?
In many cases, yes — a skilled technician can pull the cylinder from an existing knob lock and replace or rekey it without touching the rest of the hardware. This works well when the knob body and latch are in good mechanical shape. If the chassis itself is cracked, the latch is sticking, or the door prep has been damaged, a full replacement is the more cost-effective long-term fix. Our technicians assess the condition on-site and walk you through both options before any work begins.
How much should a locksmith charge to change a lock?
There is no universal flat rate because the final price depends on several factors: the type and grade of hardware being installed, whether it is a simple cylinder swap or a full mortise lock replacement, the time of day the work is being done, and how far the technician needs to travel within the Rochester area. What you should expect from any reputable locksmith is a clear, confirmed price before work starts — no estimates that balloon after the job is finished. Call us at (631) 380-4138 and we will give you a straight quote based on your specific door and lock type.
What is the non-emergency number in Rochester, NY, and when should I call a locksmith instead of the police?
The City of Rochester non-emergency police number for situations that do not require an immediate emergency response is (585) 428-7033. If you are locked out of your own home, car, or business with no safety threat involved, that is a locksmith call, not a police call. Law enforcement can sometimes assist with home lockouts in certain situations, but they are not equipped for lock repairs, replacements, or commercial hardware service. For lockouts and lock-related repairs, our team is available around the clock — call (631) 380-4138 and a trained technician can be dispatched to your location.
I've seen posts about how to pick a door knob lock online — can I just do it myself to get back inside?
We understand the frustration of a lockout, but attempting to pick or force a lock without proper training almost always causes damage to the cylinder pins, the plug, or the knob housing — damage that turns a simple lockout into a full replacement job. Beyond the hardware risk, improvised bypass attempts can also damage the door itself. The right first steps in a lockout are to check for a spare key with a trusted neighbor or family member, look for an unlocked alternate entry point, or call a professional. Our technicians are trained in damage-free entry methods and can verify ownership before proceeding, protecting both you and your property.
Can a locksmith program my key fob, or do I need to go to a dealer?
Yes, a qualified mobile locksmith with the right diagnostic equipment can program key fobs and transponder keys for a wide range of vehicle makes and models — often at your location rather than requiring a tow to a dealership. This is a service our team provides as part of our vehicle locksmith work. It is worth noting that retail key kiosks, regardless of where they are located, cannot program transponder chips or smart key fobs; that requires professional equipment and software. Call (631) 380-4138 to confirm compatibility with your specific vehicle before scheduling.
Is Rochester, New York a good area, and what should I know about home security hardware here?
Rochester is a genuinely livable city with strong neighborhoods, a walkable core, and active residential communities from the South Wedge to Pittsford. Like any mid-size city, security needs vary by neighborhood and property type. Older housing stock — and Rochester has a lot of it, particularly in the historic districts — often comes with outdated or worn lock hardware that may not meet modern security standards. Many homes still have original mortise lock sets that simply need new cylinders and proper adjustment rather than full replacement. Our local technicians are familiar with the housing styles across Monroe County and can give you honest, property-specific advice on whether your current door knob lock setup is adequate or whether an upgrade to a higher-grade keyed entry set or a deadbolt addition makes sense for your situation.
