Susan called us from Canal Way in Hackettstown after her key snapped in the lock of a black metal security gate during heavy rain. Part of the key remained inside the cylinder, leaving her outside. We assessed the jammed lock and opened the gate so she could get indoors.
Once access was restored, we removed the compromised lock mechanism. Outdoor exposure had affected its internal condition, and the hardware needed replacement. We installed a new deadbolt, aligned the latch, lubricated the mechanism, and tested the operation before handing over the new keys.
A broken key does not automatically mean every part of the entrance needs to be replaced. We inspect the cylinder, the surrounding hardware, and the door or gate alignment. That assessment helps us decide whether extraction, repair, or replacement is appropriate. Our emergency locksmith service includes assessing urgent access problems.

Door, Gate and Vehicle Locksmith Services in Hackettstown
If a gate or exterior door has become difficult to lock, tell us whether the key sticks, the bolt catches, or the entrance has to be pushed into position. Those symptoms help us prepare for the visit, but we confirm the cause by examining the hardware at the property.
For homeowners who have moved in or lost keys, we can evaluate rekeying and replacement. We consider the condition of the existing lock and whether the homeowner needs new access control or different hardware. Our door lock services include checking alignment after installation.
We also help businesses with entrance locks and provide car key replacement services for compatible vehicles. Give us the year, make, model, and key type when you call. Before completing a lock job, we test the key and locking mechanism repeatedly so you can see how the finished installation operates.
