Home Rekeying

Rekeying works by disassembling the lock cylinder and replacing the internal pin stacks with a new set sized to match a freshly cut key. When the job is complete, the original key — and every copy ever made from it — will no longer turn the cylinder. The lock body, the door hardware, and the finish all stay exactly as they were. For most Piscataway homeowners, this means zero damage to door frames, no new bolt holes, and no need to match finishes across a set of doors that were installed years apart.

The process applies equally to common door knob lock sets, single- and double-cylinder deadbolts, padlocks on garage side doors, and the mortise lock cartridges found in many pre-1980s homes throughout the older neighborhoods off New Market Avenue. A mortise lock — the rectangular unit that sits recessed inside the door edge — has a more involved cylinder than a standard knob lock, but our experienced technicians carry the pin kits and tools to rekey mortise lock hardware on-site without ordering parts or making a second trip.

Most homes accumulate locks that were installed at different times, by different manufacturers, and keyed differently from day one. A front deadbolt from Schlage, a Kwikset knob on the back door, and a mortise lock on the basement entry can all be reconfigured to accept the same key — a process called key unification or master-keying to a single user key. Our technicians assess each cylinder, select or fabricate the correct pin combination, and systematically rekey every lock in sequence so the final key operates everything smoothly.

For Piscataway families juggling school pickups, rental units on the property, or elderly relatives who need a simple single-key solution, this eliminates the bulky keyring problem entirely. It also removes the security gap created when a single copied key circulates across multiple locks — once we rekey, only the new keys you hold in your hand will open any door in the house. If you'd like that done today, call (732) 518-3699 and one of our mobile technicians can be en route within the hour.

The mortise lock is the gold standard for residential door security and is especially prevalent in the brick colonial and Cape Cod homes that line streets like Possumtown Road and Old New Brunswick Road. Unlike a cylindrical lock set that bores a single hole through the door, a mortise lock occupies a deep rectangular pocket in the door edge and integrates the latch, deadbolt, and sometimes a privacy function into one robust case. Because of that complexity, rekeying or replacing the euro-profile or oval cylinder inside a mortise lock requires a technician who knows the format — forcing the wrong approach can crack the cylinder housing or misalign the cam that drives the bolt.

Our insured technicians are trained specifically on mortise lock hardware across a wide range of manufacturers. We carry replacement cylinders and pin kits for common residential mortise formats, so if a cylinder is worn or damaged in addition to needing a new key combination, we can handle both in the same visit. We also advise homeowners on whether their existing mortise lock case is in good mechanical condition or whether an upgrade to a higher-security cylinder — with anti-drill, anti-pick, and anti-bump features — is worth considering as part of the rekey appointment.

One of the most common questions we hear — essentially, how much does a locksmith cost in NJ, what is the average call out fee for a locksmith, or how much should an emergency locksmith cost — comes down to the same honest answer: it depends on specific variables, and any responsible locksmith confirms the exact price before touching your locks. At Piscataway Locksmith, we provide a firm, upfront quote once our technician has assessed the job. There are no surprise fees after the work is done.

The factors that shape your final quote include the number of locks being rekeyed, the type of hardware on each door (a standard door knob lock costs less to rekey than a complex mortise lock with a multi-point mechanism), the time of day the service is requested, travel distance within the Piscataway service area, and whether any worn parts need replacement during the visit. Emergency locksmith calls made in the middle of the night or on a holiday reflect the true cost of having a trained technician available around the clock — something our 24/7 availability makes possible every single day. Ask how much should a locksmith cost per hour and we'll walk you through exactly how our pricing is structured before any work begins.
