"I needed to update/rekey all of the common area locks for my condo association.  Some individuals in our building had used Security Shop and liked them, so I called myself.  Setting up the appointment was very easy.  I needed to distribute keys in advance to all of the residents, so they made them for me on short notice.  The technician, Carl, arrived promptly as scheduled and was courteous, professional, and efficient.  He also offered advice that saved the Association money, by recommending that wait to replace one lock mechanism (I'm not sure of the correct word) until after having the door frame replaced. <br />  Overall, it was an excellent experience, the appointment and payment arrangements were very simple, and I'm very happy with the result.   <br />"

"The service was great. They were here on-time and got the lock fixed quickly then replaced it. They also gave me a new deadbolt due to the old one being rotted away. Great business would deff. Use them again."

"This property is being cleaned up and readied for sale.  We needed locks changed in order to have keys and make sure previous occupants did not re-enter the property.  In attempting to co-ordinate several service providers to be at the property on a certain day and time, several other locksmith companies could not confirm a specific time to arrive at the property without giving a two hour window.  Jim Ness was able to confirm the appointment and, in fact, arrived a few minutes early.  The key we had for the property did not work and Jim was able to get the lock open, change all tumblers and complete 4 locks and patio door in a two hour window.  The price was very reasonable and I would definitely call Jim for other jobs.  I highly recommend Reliable Locks. <br />"

"Great service.  When I first called, Al spoke to me for almost 45 minutes about all the details of re-keying a door as well as the pluses and minuses of various locks.  He really helped to inform my decision.  Shortly thereafter, Joseph came out to do the estimate and install.  The whole process was finished in less than 24 hours.  Would most definitely use them again."

"An hour and a half after I called Amazing Lock, my problem was fixed. They even offered -- which I accepted -- to just repair the old lock rather than charge me the cost of a new one."

FAQs for locksmith service projects in Chicago, 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.
