Broken Key Extraction in Denver, CO

Where keys get stressed in Denver

Keys snap where they turn most often and where the cylinder is oldest. The 2024 Census Bureau estimates place 24.2 percent of Denver homes in buildings of 50 or more units, against 7.7 percent statewide. In a large building the lobby and mailbox locks often belong to the building, and a key that works them several times a day is under more strain than a spare kept in a drawer.

In Capitol Hill, where the average building dates to 1920 and many apartments are now condominiums, a snapped key in a lobby or mailbox lock is a call to the manager first, since the building may control it. Older houses are a second setting: buildings from before 1940 hold 16.0 percent of Denver's homes, and a key worn smooth over decades is weaker than it looks.

Cold, thaw and the keyway

Snowmelt that runs into a keyway on a warm afternoon can turn to ice again overnight, which is one reason a key that turned easily at noon may stick the next morning. Because Colorado's days and nights can differ sharply, the cycle can repeat. Use de-icer rather than forcing the key. A stuck key is not yet a broken one, and force is usually what turns one into the other.

What not to do

• Do not keep turning or twisting harder.
• Do not use pliers or glue on the key or the keyway.
• Do not push the piece deeper with a second key or a tool.
• Do keep the broken piece and the part still in your hand; both can help match a replacement.

What to send

• a photo of the lock and keyway with the stub visible
• which lock it is: front door, unit door, lobby, mailbox, garage or padlock
• how much of the key still sticks out, if any
• whether you own the lock or the building does
• the pieces, kept together

A damaged cylinder may lead to lock repair or lock replacement. The extraction service itself is at broken key extraction, and the Denver page has the city notes.
