Abloy Electronic Switch Lock
Abloy switch locks are very similar to standard cam locks however they have electrical connectors on the back panel to allow integration into electronic systems.  Switch locks give physical key security to electronic devices and control systems and can generally be implemented fairly simply. Abloy makes 3 different models of switch lock to facilitate the various use cases:

  • EP400N - On/Off switch.  Key can be removed in either position.
  • EP401N - Momentary contact switch.  Key can only be removed in the off position.
  • EP402N - Spring loaded momentary contact switch that automatically returns to the off position.  Key can only be removed in the off position

Please note the EP400N operates similarly to the 2 position Abloy cam lock.  The lock only operates in a clockwise direction.  When turned 180 degrees it is on, when turned another 180 degrees it is turned back to off.   As Abloy Protec locks also use rotation to set the proper combination, to set the lock to a certain position the key is turned clockwise slightly past the proper position and then turned counterclockwise to remove the key. The user can feel a small notch when turning the key to indicate the proper position has been reached.



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.

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.


Cam locks are fairly easy to install.  First you need to remove the existing cam lock from the device.  To do so there is generally a large hex nut or retaining clip on the inside of the device that needs to be unscrewed to let the cam lock be pulled out the front of the device.  It may be required to also remove the tailpiece/cam on the back of the cam lock in order to be able to pull it out.  This is frequently attached with a smaller hex screw located on the back of the cam lock that can be unscrewed to assist with this.  It is then important to ensure the new cam lock has the tailpiece in the same position as the old cam lock (and should look roughly the same).   It may be again required to remove the tailpiece prior to installing the lock and insert it back once the lock is through the front of the cabinet.  Then tightening down the large hex nut to keep the cam lock in place and you should be done with installation.

  Once the lock is installed the wires can be reattached to the proper contact points on the electronic switch lock to complete the installation.
