If you own property in Rockford or Loves Park, you might wonder whether to rekey or replace your locks. Oliphant Lock and Safe can help you determine which option best protects your home. Both choices keep out anyone with old keys, but the work involved and the cost can vary widely depending on your current locks.

When Rekeying is the Best Option for Your Security

Many new homeowners and landlords choose rekeying from Oliphant Lock and Safe because it quickly updates security without the cost of new locks. A technician changes the pins inside your current lock so old keys won’t work anymore. Businesses in the State Line area also use rekeying to set up master key systems that let one key open all doors.

Recognizing When a Full Lock Replacement is Necessary

Sometimes, replacing your locks is the only way to keep your home or business secure. If your locks are rusty or stick often, rekeying won’t fix the problem. If you want to switch to smart locks or change how your doors look, installing new hardware is also the best option.

Comparing Costs and Efficiency for Homeowners and Businesses

Rekeying usually costs less because you only pay for the locksmith’s time and a few small parts. Replacing locks costs more since you also buy new hardware, and prices depend on the type and style you pick. Many local property managers choose rekeying when tenants move out to save money and still keep new residents safe.

Secure Your Property with Oliphant Lock and Safe

To choose the best way to protect your property, take a close look at your current locks and what you want for future security. Whether you’re moving into a new place or updating a business, Oliphant Lock and Safe is here to help. Call 815-227-5700 to set up a consultation or get emergency help in Rockford or Loves Park.
