Locksmithing/Dexter deadbolt lock


A 1978 RV has a deadbolt lock with Dexter written on the outside key insert area. Did Dexter Lock company manufacture this lock or Master Lock? How can I find another?

Hello Carl,

Dexter likely made that.  Master lock purchased Dexter some time in the past 10 years or so.

The main thing you need is a deadbolt that will work on your RV.  Most of those doors are thinner than most standard doors and the jamb can't generally accept a 1" throw bolt.

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.
