Locksmith in St. John, IN
By Jacob, licensed and insured locksmith and owner of Jacob Lock and Key, serving St. John and Northwest Indiana.
Jacob Lock and Key is a mobile locksmith serving all of St. John, from the established center of town to the fast-growing subdivisions along US 41 and Wicker Avenue, usually arriving in 10 to 15 minutes. We work 7am to 11pm, seven days a week. Call (219) 342-5595.
St. John has grown from a small farm town settled in 1837 into one of the fastest-growing communities in Lake County, now home to around 20,000 residents. That growth drives a lot of our work: with so much new construction, builder-lock rekeys and full-house rekeys after closing are among our most common St. John jobs, since new owners want the construction crew’s keys to stop working. The town’s main corridor, US 41, runs past landmarks like the Shrine of Christ’s Passion and a growing strip of shops and restaurants, where we handle commercial lockouts and lock changes. Out in the established neighborhoods, house lockouts and lock replacements round out the day.
Whatever the address, we come to you mobile and finish most jobs on the first visit, without damage. If you just closed on a home in St. John, rekeying every door to a single key is the first thing we recommend so old keys no longer work.
House and Car Lockouts
Locked out in St. John, whether in the established center of town or the new subdivisions along US 41, we reach you in 10 to 15 minutes and open the door without damage. We handle house, apartment, garage, and storage-unit lockouts, plus car lockouts along the Wicker Avenue corridor. We carry non-destructive entry tools, so we get you back in without harming the door.
Rekeying and Lock Replacement
With so much new construction in St. John, builder-lock rekeys are one of our most common jobs: after closing, we rekey every door so the crew’s keys no longer work. In the established neighborhoods, we rekey worn locks and replace tired deadbolts and doorknobs with Kwikset, Schlage, and Medeco hardware, keying the whole home alike to a single key.
Smart Locks
Buyers in St. John’s new subdivisions often want keyless entry from day one, and we install and program smart and keypad locks to match. We set up separate codes for family and guests and calibrate the bolt so the lock opens smoothly and the battery lasts.
Commercial and Safe Work
For the growing strip of shops and restaurants along US 41 and Wicker Avenue, we handle storefront and office lockouts, master-key systems, and lock changes after staff turnover. We also open home and office safes without damage when keys or combinations are lost.
For upfront pricing on any of these services, see our locksmith prices page, or call (219) 342-5595 for a quote.
