"Pat was very accommodating, helpful, and professional. We had originally scheduled with another locksmith (big mistake!) and due to the extremely poor service and potential scam of the other company, my husband and I called Bells mid-day on a Saturday and Pat came out himself within 20 minutes. Pat was great, answered all of our questions, and did an outstanding job. The pricing is upfront and reasonable. Will definitely use again and recommend to others.

"Matt F. from Chicago Locksmiths came to unlock my door that I locked myself out of. He was fast, efficient and courteous. He observed all COVID-19 safety protocols too. What else could you ask for in a locksmith. The price not outrageous either ($110). I would highly recommend Matt F. from Chicago Locksmiths."

"I had used this company a year ago to change my locks and had no hesitation in using them again when I unfortunately had to change them a second time. The locksmith was prompt, polite, and worked quickly to complete the job. I was again very pleased with the services.

"Locked my keys in my car in a parking lot and had no idea what to do. Called these guys and they showed up in under 30 minutes. Got me back in my car fast, no damage, and the price was totally fair. Will absolutely call them again if I ever need a locksmith."

FAQs for locksmith service projects in Naperville, IL

The installation timeframe varies based on door preparation and lock complexity. For doors already prepared with appropriate holes, installation might take 15 to 30 minutes. New installations requiring drilling take one to two hours. First-time DIY installers should allocate additional time to ensure proper alignment and function. Professional locksmiths complete standard installations efficiently due to their specialized tools and experience.

Most residential doors can accommodate deadbolts, but certain door types present challenges. Solid wood and fiberglass doors accept standard deadbolt hardware, while metal doors require specialized drilling equipment. Hollow-core interior doors lack the structural integrity to properly support deadbolts without additional reinforcement. Doors should be at least 1⅜ inches thick to properly house standard deadbolt mechanisms.

Door warranties remain valid when deadbolts are installed according to the manufacturer's guidelines. However, improper installation that damages the door structure might affect warranty coverage. 

Before modifying any door under warranty, review the documentation for specific limitations or requirements regarding hardware installation. Some manufacturers provide templates or guidelines for acceptable lock placement to maintain warranty protection.

Rekeying offers a more economical alternative to complete replacement when you need to change access, but the lock mechanism remains in good condition. This process involves reconfiguring the internal pins to work with a new key while retaining the existing hardware. For homeowners with multiple locks, rekeying provides the convenience of using a single key for all entry points while maintaining security.
