Single Cylinder Deadbolt

A single cylinder deadbolt assembly includes a keyed cylinder for the outside of the door, a thumbturn for the inside, key/keys (as is applicable for the specific lock type), and the bolt, door hardware and screws needed for installation.


BiLock is a high security brand that features a unique Quick Change Core (QCC) system and is based out of Australia. BiLock features a unique U shaped key that utilizes a pin and sidebar system that is extremely pick resistant and completely bump proof making it a popular choice by casinos and businesses around the world. The QCC system from BiLock works in all of their locks and allows for the instant removal of the core of the lock with a control key to allow a new core to be easily inserted. Virtually all of their locks can use the same key and interchangeable QC cores. BiLock has extensive retrofitting and compatibility features allowing it to be used in many existing locking systems. For more details please see our BiLock Brand Information page.

Key Type / System

There are two primary key types/systems for BiLock: EX / QC both are part of the New Generation (NG) BiLock system.  Each key type also influences the build of the lock itself.  Not all locks support all key types, however most locks do support both.  The EX is BiLock's original key type and has no specific features.   The primary key type is BiLock's innovative Quick Change Core (QCC) system. The QCC system is an interchangeable core meaning that in addition to the standard operating keys you have a control key.  With the control key you are able to remove the core of the lock and insert the core from another QC lock (or spare core).  This process can be done in under 30 seconds and without removing the lock from the door or requiring any tools.  Some customers have even used the QC system on their homes and businesses to change out their door locks for sitters, maids, or construction workers. For more details please see our Choosing A Brand page.  Any QC lock will come with one control key and one operating key.   When ordering additional QC keys please specify the key type (control or operating) in the notes field on the final page of checkout (where you enter your credit card) otherwise we will assume they are standard operating keys.   QC cores can be purchased separately on our BiLock Extra QC Core page.   There is no real reason not to get an QCC lock even if you do not plan to use the QC system now you at least have that option for later.   BiLock officially also has the First Gen and EX short / D9 systems, while we do not show these as a product option they are in stock and contact us if you need one of these systems.

Keyed Alike / Master Keying

Master Keying and Keying Alike are both services we are happy to offer however they do require that all the locks are the same key type (EX/Ex Short/QC). 

We are able to key your locks alike(to the same key) during ordering at no cost.  We can also master key(see our Master Keying Page) your locks starting at $15 per cylinder.  Keyed alike means that if you order two padlocks and a deadbolt from us we can key them all to operate on the same key.   To order two or more locks keyed alike, just select "keyed alike" under keying for each lock and all locks that are the same color will be keyed the same.  During checkout there will also be a notes area and you can comment on how you want the locks keyed if you wish to provide additional clarification.   It is important to note that when keying alike you do not get more keys for each lock you order, just the initial lock's number of keys.  This means no matter if you order 2 or 5 padlocks keyed alike, you will only get 2 keys total.  If you require additional keys just order extra keys.  There is no additional charge for keying alike.  Master keying can allow you to allow some keys to open some locks and other keys to open all locks. You can specify your desired master keying in the notes area when checking out, or you can simply put a note in to call, and we will call you to discuss your needs.  If you are looking to have locks or keys to a previous order please see our keyed to a previous order page.

Key Look

BiLock keys can have various multi-colored key heads.  The key head is actually made up of two different parts, an inner part and an outer part.  They can be the same or different colors.  

Extra Keys

Please note when ordering extra keys you are ordering extra keys per lock.  This means if you select 3 extra keys and then order a quantity of 2 locks you will get 6 extra keys.  To order the correct number of extra keys you can divide the number of extra keys by however many locks you are ordering and put that under extra keys.  The other option for extra keys is to add a quantity of 1 of the item you are ordering to your cart with the correct number of extra keys, and then go back and add however many more of the lock you want with 0 extra keys.  It will mean you have to pick the options for the product twice, but will ensure you get exactly how many keys you want.


Most standard doors do not have any issue working with BiLock deadbolts as long as the door is either 1 3/8" thick or 1 3/4" thick. 

Most of our customers install their deadbolts themselves, however if you do want to hire someone we generally recommend a carpenter over a locksmith, they will generally be cheaper and do just as good if not better of a job.  In order to install the deadbolt you will have to remove any existing deadbolt on your door.  This can generally be done with a simple screwdriver removing the two screws on the inside of your door holding the inside and outside together.  The two screws on the side of your door holding the bolt in place, and finally the two screws on your door jamb keeping the strikebox/plate in place.  For a copy of the installation instructions (included with the lock also) see
