Locksmithing/core fell out of knob


lock fell apart
lock fell apart  
The core lock part fell out of the knob on the door from the garage to the house.  I'm worried someone tampered with it and used it to make a key to my house.

Here is a picture.  I've put it back in the knob and I'm using the deadbolt above the know to secure the door.  Can someone make a key to my lock (one key for all my locks) if they have this part?


Hello David,

This is a common problem with Kwikset and Titan locks, deadbolts included.

If they have the lock body (the part that fell out) they can make a key if they know what they are doing, or they could take it to a locksmith to have one made.

Generally this type only falls out of knobs if the key with a slot in the bottom of the blade is used.  These are included with new locks but can be made from an existing key.

It's unlikely that someone made a key for your lock but it is possible.  I'd recommend rekeying your locks to make sure nobody has a key.  You may want to change to a better quality lock instead.

I do not answer Safe or automotive questions. Period. I am knowledgeable in almost every area of Locksmithing. This includes locks, keys, lost keys, residential and commercial lockouts, rekeying, masterkeying, high security locks, access control, electric locks, security cameras and home safety. I have been running an online business since 2004 where I sell all types of lock and security hardware to everyone from apartment renters to business owners to the US government. Before that I started a locksmith service in 1999. I deal with many types of security equipment including high security safe locks, heavy duty padlocks, exit devices, biometric readers, electric strikes, magnetic locks, full surface hinges and I only sell what I personally stand behind 100%. The online business has given me a more in-depth look at the locksmithing industry, helping me to learn more about each and every product that I offer, as well as products I don't have but end up finding for customers to solve any issues they have with security or door hardware.

Please don't submit any automotive or safe questions as these aren't areas that I can help in.
