Lock Rekeying and Master Key Systems

Lock Rekeying

Reasons for Rekeying Your Locks

There are many reasons one may want to rekey their locks.  Some of the more common reasons for a rekey include moving into a property, divorce, change of renters and untrustworthy loved ones. 

If you recently purchased a home (new or used) you should rekey your locks before you even move in.  For new homes you will find that the contractor and maybe even subcontractors have had the keys and could have made copies without you knowing.  If you are purchasing a prior owned home, the owner could have copies of the keys and may have given keys to relatives, friends and even your new neighbors.  The only way to be sure your new home is secure is to have all locks rekeyed as soon as possible.


Price to Rekey
The price to rekey a location depends on a few factors.  First, the type of locks being rekeyed.  Most standard residential locks only require a minimum rekey charge, but there are exceptions for some types of locks.  Many commercial locations have exit devices, high security locks, restricted keyways and other devices that may demand a higher rekey charge.  In most cases it is only a few dollars more per lock for these devices.  A rekey is a very economical way to restrict access to a location that may have keys in the wrong hands.  Give us a call today to set up an appointment at 717-564-2230 or 1-866-SHEARER.


What Needs Rekeyed?

In most cases it is best to rekey all locks, but sometimes when a location is masterkeyed only a few need to be done.  If you plan to rekey all your locks, you can calculate how many need rekeyed by counting the number of places a key can be inserted into a lock which is a cylinder.  Most locks only have one cylinder, but there are exceptions.  A double cylinder deadbolt which are fairly common in the United States has a cylinder on the inside and the outside of the door.  These locks are common on doors that are next to glass windows.  If someone were to break the window, they would not be able to open the door without a key.  There are drawbacks to this type of lock.  If you house catches fire - how do you get out?  If you don't have a key handy it will be a lot harder to exit your home in the event of a fire.  We do not suggest the use of double cylinder deadbolts, but we will rekey them if requested.


Can It Be Keyed to One Key?
If your locks currently work on one key, it will not be a problem rekeying and making them all work on one key.  If you have more than one key to operate different locks it is possible that some of the locks will need replaced in order to make your entire property work of a single key.  This all depends on the locks you have on your location and the type of keyway the locks have.


Do Not Duplicate

The words "Do Not Duplicate" on your key means very little.  Many places will duplicate a key that states do not duplicate.  If you request a key that says do not duplicate, how do you get copies of the keys made when the time comes that you need more keys?  Here at Shearer Locksmith, we do not duplicate keys that say do not duplicate without written authorization from the building owner or manager, but many places will do it without question.  If you do not want your keys duplicated there are ways to control who has keys and who can get them duplicated.  If this is something that interests you, look into our High Security Locks and Restricted Keyway Systems.

Master Key Systems


Reasons for Setting Up A Master Key System
A master key system is basically a key system with levels.  Lets say you have a building with offices inside and a supply room.  A master key system would allow you to set up several levels of keys.  The top level would be the "master key level" which would operate all the locks in the building including the exterior doors, interior office doors and the supply room.  The next level of the system could contain a series of keys which each have their own function.  A system can be set up to where each office has a key that also opens the main doors, but not the other offices.  This system can also be set up so those keys that operate the offices also operate the supply room.  Perhaps you only want some of the people's office keys to open the supply room - not a problem.   Basically the system can be set up so everybody has a key that only gets them into the rooms they are supposed to be in.  If you want maximum control over your employees and doors, an access control system is the way to go.  With an access control system, you can control who has access to every door and when they can access it.  Most access control systems also keep track of who opens and when a door is opened.  Find out more on these system at our Access Control Systems page.


Master Key System Maintenance
If you choose to have a master key system set up with Shearer Locksmith, we will maintain your keying information so any future rekeying will not conflict with current keys in your system.  When new locks are keyed or locks are rekeyed we will utilize the next numeric sequence on your system so all the keys that are supposed to work sill do and the keys you are trying to eliminate do not work.  Once your system is set up and your locks are keyed it will be very simple to keep things secured and running smoothly. 


Pricing a Master Key System
We would be happy to come out and give you a quote on a master keys system.  Price has a lot of factors including the type of locks, number of locks, number of master key levels and the number of keys needed.  If you have a very simple system with only a few doors we may be able to give you an estimate over the phone.  To request a quote, please request more information here.


High Security and Restricted Keyway Master Key Systems
If you have or are interested in restricting who has keys and who can duplicate keys, we can help.  We can custom tailor a master key system that utilizes restricted keys or high security locks with restricted keys.  In both cases, keys can only be copied with proper identification and a signature controlled logging system.

If you are interested in getting your locks rekeyed or have a master key system set up.
