Rekey or Replace? What to Do With Your Locks After Moving In

Rekeying a lock means a skilled locksmith disassembles the cylinder and replaces the small internal pins that correspond to your existing key. Once rekeyed, every previous key copy becomes useless — only your new key will work. The lock hardware itself, whether that is a door knob lock, a deadbolt, or a full mortise lock, stays in place. Rekeying is possible on most standard residential locks as long as the hardware is in solid working condition and the lock brand is consistent throughout your home (mixing Schlage and Kwikset cylinders on the same job, for example, can add complexity). It is fast, it is thorough, and it gives you complete control over who holds a working key from day one.

Full lock replacement, on the other hand, means removing the entire lock assembly and installing brand-new hardware. This makes the most sense when your current locks are worn, damaged, outdated, or simply not the right grade of security for your needs. It is also the right move when you are upgrading to a mortise lock — a mortise lock is a heavy-duty, recessed lock system built directly into the door's edge, offering significantly more resistance to forced entry than a standard surface-mounted lock. Mortise locks are common in older Bound Brook homes and historic properties, and a qualified locksmith can assess whether your existing door and jamb can accommodate one without major carpentry work.

If your locks are relatively new, functioning smoothly, and all keyed to the same brand, rekeying is almost always the most practical choice after moving in. You get a fresh start — no old keys floating around with former owners, contractors, or whoever the previous occupants handed copies to — without the cost and time of full hardware replacement. A trained locksmith can rekey every exterior door in a typical Bound Brook home in under an hour, and you walk away with a single master key that works every lock on the property.

One scenario where rekeying really shines is when a home has a quality mortise lock already installed. Mortise locks are built to last decades, so if the hardware is sound and just needs a new cylinder configuration, rekeying it is the sensible call. The same logic applies to solid door knob lock sets on interior doors — if they work well and are from a reputable brand, there is no reason to replace them just because you moved in. Get them rekeyed, have spare keys made, and store a backup somewhere secure outside the home.

There are clear situations where replacement is the right call. If the locks on your new home are old, stiff, have visible wear on the keyhole or face plate, or if they are low-grade builder-grade hardware that came standard with the property, replacement gives you a meaningful security improvement. The same applies if you want to add a deadbolt where there was not one before, or if different exterior doors have different lock brands that cannot be rekeyed to a single key. A single-key solution for every exterior lock — called a master key or keyed-alike setup — is something a professional locksmith can build into a replacement plan from the start.

If security is a priority, this is also the right moment to ask your locksmith about upgrading to a mortise lock on your primary entry door. Unlike a standard cylindrical lock, a mortise lock sits inside the door itself and uses a multi-point bolt system that is dramatically harder to kick or pry. Many Bound Brook homeowners are surprised to learn that their older front doors were originally built with mortise lock pockets already routed in — which means the upgrade is easier and more straightforward than they expected. An experienced locksmith can inspect the door, confirm whether the existing pocket is usable, and handle the full installation in a single visit.

Moving day chaos is a real lockout risk. You hand a key to a helper, prop open the back door, and then suddenly realize you are locked out and nobody has a key on them. Knowing what to do if locked out of your house before it happens can save you serious stress. First, calmly check every exterior door and window — sometimes a helper accidentally left a side door unlocked or a garage door is still accessible. Check with anyone else on the property who might have a spare. If you have already set up a lockbox or left a spare key with a trusted neighbor, now is the time to use it.

If none of those options pan out, do not try to force entry yourself — you risk damaging the door, the frame, or the lock in ways that will cost significantly more to repair than a professional lockout call.

One of the most common questions new homeowners ask us is: how much does a locksmith cost in NJ, or more specifically, what is a locksmith call out fee? The honest answer is that no responsible locksmith should quote you a flat number without knowing the specifics of your job. Several factors shape the final price: the type and brand of your existing locks, the number of doors involved, whether you need rekeying or full replacement, the grade of hardware you are selecting for a replacement, the time of day (emergency locksmith calls outside of standard hours involve different logistics), and how far our technician needs to travel to reach you.

What we commit to at Bound Brook NJ Locksmith is transparency: before any work begins, we confirm an exact, upfront price with you — no surprise fees added after the job is done. The same principle applies whether you are asking how much does a local locksmith charge for a quick rekey or a full mortise lock installation across multiple entry points. You approve the number first, then we work. That is the standard every homeowner deserves, and it is how we operate on every single call, 24 hours a day, seven days a week.
