Lock Installation Services

A properly installed lock should fit the door, support everyday use, and provide the level of access your property requires. Since 2017, I have provided lock installation services for homeowners and businesses throughout the southwest Chicago suburbs and nearby Northwest Indiana.

Lock Installation for Homes & Businesses

Different entrances have different requirements. A home's primary entry door may be used differently from a commercial entrance that employees or customers access throughout the day.

Residential Lock Installation

Residential Lock Installation

I install locks for homeowners adding new doors, replacing doors during renovations, or making planned security improvements.


I can help you choose lock hardware that works with the entrance and fits your household's everyday access needs. If you are interested in moving away from traditional keys, I can also discuss keyless entry options for your home.

Commercial Lock Installation

Commercial Lock Installation

Commercial doors may require lock hardware suited to frequent use and different access needs. I install locks for businesses adding entrances, renovating spaces, replacing doors, or updating existing security.


For businesses with multiple entrances or different levels of access, I can also help determine whether a keyless entry or master key system would be useful.

Upgrading from traditional keyed entry

If you already have a lock in place but it is damaged or unreliable, lock replacement may be more appropriate. If your goal is simply to prevent old keys from working, rekeying may be another option.

Choosing Lock Hardware for Your Door

Choosing a lock starts with understanding the entrance itself. I consider the type of door, whether the property is residential or commercial, how frequently the entrance is used, and how you prefer to manage access.

Traditional keyed locks may work well for many doors, while keyless entry can offer another option for customers who want to reduce their reliance on physical keys. Commercial properties with several doors may also benefit from a system that makes access easier to organize.

I help you select lock hardware based on the door, how the entrance is used, and your access needs.
