Lockable Thumbturn Deadbolt
The Abloy lockable thumbturn deadbolt is the best solution for many deadbolt installations.  It offers the security of a double deadbolt with the convenience of a normal single cylinder thumbturn deadbolt.  Most high security lock manufacturers try to accomplish this by selling 'captive key' deadbolts.  Captive key deadbolts generally are nothing more then a double sided deadbolt in which a key is left on the inside with a key head that looks like a thumbturn.  The major downside of this is the fact you have a working key sitting in the lock 24/7 which someone could possibly quickly borrow and make a copy of.  The Abloy lockable thumbturn deadbolt is a far more elegant solution, being a true locking thumbturn.  It features a thumbturn on the inside like a single cylinder deadbolt and when it is in normal mode can be turned like a normal thumbturn deadbolt.  You can then use the key to enable 'secure' mode in which it can no longer be turned by hand, completely disabling the inside thumbturn from effecting the deadbolt at all.  This allows it to function like a normal thumbturn when you are at home, but then at night or when you leave the house for an extended period of time, you can enable the secure mode to ensure it cannot be unlocked without the key.   No matter if you have glass next to the door or a window nearby, the lockable thumbturn allows for peace of mind whenever you need it.  The Abloy lockable thumbturn deadbolt has one other unique feature in the high security world in that it has no exposed inside screws.  The screws can only be accessed when the thumbturn is not in secure mode.  When the thumbturn is in secure mode it is impossible to remove the deadbolt from the door no matter where you have access.   This feature along with the locking thumbturn also means that even if a burglar was able to get into your house he would not be able to open the door from the inside making it far harder for them to make off with your property as they would have to go back out the way the entered.



  • ANSI Grade 1 (highest grade) rated deadbolt for extreme physical attack resistance
  • Case hardened steel body and hardened steel cylinder provide maximum resistance to drilling
  • High Security H2X extreme 2" hardened bolt can withstand 2 tons of force
  • 1/4"(6mm) thick hardened steel retaining screws to stop prying
  • Hardened steel bolt shield to stop ice pick attacks
  • Reinforced steel strike box with 2" anchor screws
  • Solid rotating collar so wrenches and pliers just slide off


For additional security and to avoid prying you may want to consider the Expanding Bolt for Abloy Locks.  This bolt features a unique double ball bearing system in the end of the bolt that locks into a reinforced strikebox so that even if the door is attacked or pried the bolt will not be able to come out of the strikebox without being unlocked.  It does not require any special modifications to either your door or your door frame.   We also offer door frame and door reinforcers which you can find under the Guards/Tools category. For business users or those concerned with advanced physical attacks (or lock defacement through glue or other substances) we recommend considering our Geminy Shield product.


Abloy is one of the most reputable high security lock manufacturers in the world. Abloy is based out of Finland and their current top of the line lock system is the Abloy Protec/Protec2 system. The Abloy Protec system came out in 2001 and features a unique rotating disk based system with a disk blocking anti pick system that is unique to them. It is completely bump proof and extremely pick resistant (no known picking attacks have been successful). It is well respected as one of the top of the line high security locks in the world. It has one of the largest key spaces of any high security system with over 2 billion possible keys. Virtually all Abloy locks can be keyed to work with the same set of keys. The Abloy Protec2 was introduced in December of 2012 and it makes some refinements to the Abloy Protec system. The primary features include minor additional drill resistance, harder to copy keys with an interactive element and an extended patent through 2031. To order locks in the Protec2 system select “Protec 2 Elite” under key profile on the product options. For more details please see our Abloy Brand Information page.

Key Profile / System

Abloy currently has two different systems of locks the Abloy Protec2 and the Abloy Protec.  First you must decide which system you would like to buy, most locks are available in both systems.  For more information on the Protec1 verse the Protec2 please see our Abloy Brand Information page. To order a lock in the Abloy Protec2 you must select a key profile that has the number 2 in its name (ie "Protec2 Elite" or "Ruby2 Exclusive").  Next you have a choice of key profile, the key profile of a lock primarily is an issue of key control.  Legally the Protec Elite and Ruby Exclusive key profiles have the same level of key control, no dealer other than the dealer who originally issued the keys (or the Factory) can cut more keys.  Technically, with the standard Protec Elite key profile, all Abloy Protec/Protec2 dealers in the US have access to this key blank.  This is a slight security risk as it does mean they could duplicate a Protec/Protec2 Elite key if they wanted to (but they would break their contract with Abloy in doing so and we have yet to hear of a dealer doing so).   Our Ruby Exclusive key profile is a key blank that is only issued to us, which removes the option for another Abloy dealer to duplicate your ruby key as they do not have access to the key blanks.  A Protec Elite key will not even fit in a Ruby Exclusive lock.   The Ruby Exclusive is a very secure level of key control giving peace of mind to even the most worried lock owner.   Having an exclusive key profile can also be useful if an eventual attack against the Abloy Protec is found.   While it is hard to speak about something that has not happened, many advanced rights escalation attacks, or advanced attacks against high security locks, require having a key (or key blank) that fits the lock.  With the Ruby Exclusive you will make it harder for an attacker to have access to a fitting key.

Emergency Key

The Emergency Key option allows us to specially key double deadbolts and lockable thumbturn deadbolts to make them better suited for residential or primary door environments.  An emergency key is a special key that will only open the lock from the inside, and not from the outside.   This way an emergency key can be kept near the door and in case of an emergency used to open the door to get out.  As the emergency key will only work from the inside, if it is lost you do not need to worry about someone being able to open your lock from the outside.  Frequently people keep the emergency key in a near by drawer or hanging on a string for easy access. 

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 profile (Ruby Exclusive or Protec Elite). 

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

Abloy keys have a variety of color inserts that can be selected to help keep track of your Abloy keys from one another.  Below, you are able to pick a color for your key indicators. If you want a different color for one or more of the keys, please specify the colors you want in the notes area during checkout.  In addition, Abloy keys can have an optional plastic key head.  Our Abloy Plastic Key Heads are found under the Accessories category.  The plastic key head does not block the color indicator dots.

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 Abloy deadbolts however to ensure your door will work with an Abloy deadbolt please see our Abloy Deadbolt Door Requirements page. 

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
