Dozens of workers may have had access to your property before it was finished. Rekeying is the only definitive way to ensure safety.
When purchasing a resale home in Lakewood Ranch, you inherit the lock history of the previous owners.
Older locks can suffer from worn internal pins, making them susceptible to manipulation or key jamming.
Residential lock rekeying is the process of altering the internal pin and tumbler mechanism of your existing door locks so that an old key will no longer operate them. Instead of replacing the entire doorknob or deadbolt hardware, which can be costly and unnecessary, a professional adjusts the internal configuration to match a brand-new set of keys.
This service is particularly beneficial for new construction homes and recent real estate purchases in Lakewood Ranch. When Cris performs a rekey, he carefully disassembles the lock cylinder, replaces the old pins with new ones of different lengths, and cuts new keys to match.
Sound hardware usually needs new key control, not a full replacement.
Many homeowners confuse rekeying with complete lock replacement. Lock replacement involves removing the entire hardware unit—the handles, knobs, and deadbolts—and installing brand-new fixtures. This is typically recommended when your current locks are severely damaged.
Rekeying, on the other hand, is a much more cost-effective solution when your existing hardware is still in good working condition. By simply changing the internal pins, you achieve the exact same level of upgraded security as a new lock, but at a fraction of the cost.
Rekeying utilizes your existing hardware, saving you the significant expense of buying brand-new locksets.
Whether it is a builder master key, a subcontractor's copy, or a spare from the previous owner, rekeying ensures safety.
If you have multiple locks of the same brand, we can often rekey them all to operate on a single, convenient key.
We provide clear, upfront pricing over the phone. A typical 3 to 4 lock home costs between $100 and $150 total.
