You just moved into a home off East Saddle River Road, and somewhere out there, a previous owner still has a key that fits your front door. Or maybe you came home to find signs of a break-in attempt on your mortise lock and you're wondering whether to fix what you have or start fresh. Either way, you're facing the same core question homeowners across Saddle River, NJ ask every week: should you rekey your locks, or replace them entirely? The answer isn't one-size-fits-all — it depends on the condition of your hardware, your security goals, and how many doors you're dealing with.
This guide breaks down both options honestly, walks you through the real scenarios where each makes sense, and explains what a trained locksmith looks for before making a recommendation. Whether you're protecting a single-family home near Chestnut Ridge Road, a multi-unit property, or a small business on the commercial corridor, understanding the difference between rekeying and replacing can save you time, stress, and unnecessary work.
Frequently asked questions
How do you rekey a lock, and can I do it myself?+
Rekeying involves removing the lock cylinder, swapping out the driver and key pins for a new configuration, and cutting a matching key. Rekey kits for common Schlage and Kwikset locks are sold at hardware stores, and some mechanically inclined homeowners do complete the process themselves with patience and the right tools. However, the process is more error-prone than it looks — dropping small pins, installing them in the wrong order, or improperly reassembling the cylinder can leave you with a lock that does not function reliably. For mortise locks, smart locks, or any high-security cylinder, professional rekeying is strongly recommended. A skilled locksmith completes the job correctly the first time and confirms everything functions perfectly before leaving.
Can you rekey a lock to match an existing key I already use?+
Yes, this is called keying alike, and it is one of the most useful services a residential or commercial locksmith offers. A locksmith measures the cut depths of your existing working key, then pins new or existing lock cylinders to match that exact pattern. The result is a single key that opens multiple locks across your property — front door, back door, garage entry, and so on. The only limitation is that the locks involved must use compatible keyways. A locksmith can assess whether your existing hardware allows for keying alike or whether a hardware change makes more practical sense.
How much does a locksmith cost in NJ for a rekey vs. a full lock replacement?+
The price for either service in NJ depends on a handful of specific factors: the type and brand of lock being serviced (a mortise lock involves more labor than a basic door knob lock), the number of locks involved, whether any parts need to be sourced and installed, the time of day the service is needed, and the travel distance to your location. Emergency locksmith calls after hours or on weekends factor into scheduling logistics. What we always do before starting any work is give you a confirmed, exact price upfront so you know precisely what to expect. There are no surprise charges added after the job is done.
What is the difference between a mortise lock and a standard deadbolt, and which is more secure?+
A standard deadbolt is a surface-mounted lock installed in a bored hole through the door. It is widely used, easy to install, and effective for most residential applications. A mortise lock is set into a recessed pocket cut directly into the door's edge, making the lock body part of the door structure itself rather than a separate cylinder sitting in a drilled hole. Because the mortise lock body is embedded in the door, it is generally more resistant to physical attacks like kick-ins and wrench attacks. Mortise locks are the standard choice for commercial doors and are increasingly popular for high-security residential applications, particularly on main entry doors. A trained locksmith can assess your existing door preparation and recommend whether your door is already set up for a mortise lock or whether a mortise conversion makes sense for your situation.
