Questions about Lock Repair & Replacement

Troubleshooting Guide

View All Troubleshooting Guide
Why is my key suddenly difficult to turn?

A worn key, debris, a failing cylinder, or pressure from a misaligned door can cause resistance. Do not force the key. Note whether the problem happens with another authorized key and ask St. Louis Lock & Key to inspect the lock.

Why does the deadbolt work with the door open but not when it is closed?

The bolt and strike may no longer align because the door or frame has shifted. Avoid repeatedly forcing the bolt or modifying the frame yourself. St. Louis Lock & Key can check alignment and lock condition.

What should I do if a key breaks inside a lock?

Stop turning or pushing on the broken key and keep the remaining piece. Glue and improvised extraction tools can damage the cylinder. Contact St. Louis Lock & Key for broken key extraction and an assessment of why it happened.

Why does the lock cylinder feel loose or spin?

Loose mounting hardware or an internal failure may prevent the lock from operating securely. Do not rely on a door that will not lock correctly. Arrange an inspection with St. Louis Lock & Key and use another secure arrangement while waiting.

What if my lock was damaged during an attempted break-in?

Move to a safe place and contact police if there is an immediate threat or a crime to report. Avoid disturbing evidence. When it is safe to arrange repairs, St. Louis Lock & Key can assess the damaged lock and replacement needs.

Can you repair a lock instead of replacing it?

Yes. St. Louis Lock & Key offers lock repair as well as replacement. We can assess sticking mechanisms, loose hardware, and damaged latches to determine whether repair is suitable or replacement is the better option.

Can you install a replacement lock or deadbolt?

Yes. St. Louis Lock & Key provides lock replacement and installation. We will discuss the door, existing hardware, intended use, and compatible options before work begins.

Do you remove broken keys from locks?

Yes. Broken key extraction is part of our lock repair services. Stop using the damaged lock and contact St. Louis Lock & Key; pushing tools or another key into it can make the repair harder.
