Expected Timeline for Rekeying Your Lochearn Locks
The duration of a lock rekeying service in Lochearn depends on several factors, including the number of cylinders needing rekeying and whether you want all exterior doors keyed alike. A typical rekeying job for a standard residential home with a few doors usually takes less than an hour per lock after the technician arrives.
More complex requests, such as implementing a master key system or resetting SmartKey-style cylinders, may require additional time. Our technicians work efficiently, and the process is often completed within a single visit, allowing you to quickly secure your home in Baltimore County with new keys.
The Precision Process of Residential Rekeying
Rekeying involves carefully disassembling the lock cylinder to access its internal pinning mechanism. The existing pin stack, which corresponds to your old key, is removed. A new set of pins, known as bitting, is then installed to match a brand-new key configuration.
Once the cylinder is reassembled and tested, a fresh set of keys is cut on site using our mobile equipment. This process renders all previous keys for that lock useless, providing you with enhanced security while retaining your existing door hardware. We can also key-alike multiple locks so one key operates all your exterior doors.
Benefits of Rekeying Versus Full Lock Replacement
For many Lochearn homeowners, rekeying offers a practical and economical alternative to replacing entire lock sets. If your current locks are in good working order and aesthetically suit your home, rekeying allows you to upgrade security significantly without incurring the higher cost of new hardware.
This service is particularly beneficial when you move into a new house, have a change of tenants, or if you suspect a former contractor or cleaner might still have a copy of your keys. You get the peace of mind of fresh security with the convenience and cost savings of keeping your existing lock mechanisms.
