"Rory knows his business! The latch bolt had seized up in the strike plate because the antique wooden door had swollen with all the rain and was wedged within the door frame so tightly that it was impossible to open. Rory knew right where to place the tip of a screwdriver to pop that old door right open! It was like magic! Heâ s my hero! If you need a real professional locksmith, give Arvada Lock and Key a call and ask for Rory!"

FAQs for locksmith service projects in Denver, CO

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.
