With such an array of lock options available, how do you decide which is the most suitable for your application? By answering some simple questions to determine your requirements, e.g. how frequently the code needs to be changed, how regularly the door will be in use, whether you require a fire rated lock etc. - it can narrow down the choice of locks from over one hundred variants to just two or three models. Whether it be an installation at home, in healthcare, educational, commercial or residential environments, if you have a door, we have a lock for you.

For more information on specifying the correct lock for your application, contact Codelocks Customer Services.


Push button locks are often bought to replace locks with keys. Key management can be a major concern for facility or estates managers looking after large public buildings, like hospitals or universities, for example, where you have large numbers of people constantly moving around. Keys inevitably get lost or stolen, so new keys have to be issued and locks have to be changed, which takes time and money to manage on a large scale. Push button door locks do away with the need for keys.


Before purchasing a lock, it is worthwhile examining where and how it will be used and what features it should have. Entry level locks are suitable for light volumes of traffic, whereas heavy duty locks are more robust and are designed for higher volumes. Push button locks are available in a number of different finishes, such as stainless steel or polished brass and have either knob or lever handles.

Some locks have a Back to Back facility, where the push button digits are on both sides of the door. Key override, which allows the use of one key to access multiple locks, is a useful function where facilities managers or maintenance personnel need regular access in a building that has many locks all with different combinations.


There are many different types of push button lock available to suit a variety of access control needs. Push button locks are either mechanically or electronically operated and can be used as primary locks on internal and external doors. The locks can be fitted to most types of door, including aluminium, wood, even glass. There are push button locks that can be easily fitted in place of existing key cam locks supplied as standard on a wide range of lockers, cabinets and cupboards. The locks enable the user to implement a quick and cost-effective solution to the problem of unauthorised access and can be fitted as and when needed, one door at a time.


No maintenance of the working parts is necessary. DO NOT oil. To maintain the finish the lock should be cleaned regularly with a soft cloth. A silicone spray or similar should be used to provide a protective film against grit and grime. Oil based sprays such as WD-40 should not be used.

If you have a KL1000 NetCode (also known as the KL1060 or KL1060C2) you will need to create an account on our Codelocks Connect Portal.

Once the account has been created you can add your lock, this will involve inputting a programming sequence into the lock when prompted. As soon as this is done you can generate a NetCode from the portal.


The cam is catching on the keep or door frame. This can happen if an incorrect cam has been chosen for your door type, or if the cam has taken an impact and bent slightly.

This can be corrected by removing the cam and replacing it, or by slightly bending the cam back into its original position so it no longer catches. There should be a bit of play when pushing or pulling on the door with the turn knob in the rest position.


If the batteries are flat, the KL1000 range has been designed so that an external PP3 battery can be placed against the contact points surrounding the blue and red LEDs. This will power up the lock so it can be opened in order to replace the batteries.

  1. Place the contact points of the PP3 battery against the content points surrounding the blue and red LEDs.
  2. The positive + PP3 terminal against the red LED contact point and the negative - PP3 terminal against the blue LED. We sell a battery override tool to make this step a little easier. 
  3. Enter the Master Code.
  4. The motor will withdraw the locking pin allowing the lock to be opened.
  5. Fit new batteries by removing the upper fixing bolt and swinging the lock over the edge of the door.
  6. Refit the lock.

Note: If the power level of the lock falls too low, both the blue and red LEDs may flash continuously after the batteries have been replaced. If this occurs, you will need to reset the lock and if previously registered on the Codelocks Connect Portal, re-initialise the lock (instructions for re-initialisation are displayed on the lock details page of the portal).


If the red LED flashes after entering the code, it has not been recognised. Try another code or enter the Master Code to gain access. The Master Code will normally be held by management or staff responsible for the building.

If the blue LED flashes after entering the code and does not open, the problem may be because the cam inside the locker or cabinet is in bind against the keep or frame. Apply firm pressure on the door face and attempt the code agan. Once access is gained the cam needs to be re-adjusted to prevent the bind happening again. This can be done easily by applying pressure to the cam with a set of pliers to bend it back into shape.

If there are no flashes the batteries have been exhausted, to gain access you will need a 9v PP3 battery.

  1. Position the positive terminal of the battery against the red LED and the negative terminal against the blue LED.
  2. Once contact has been made, the blue and red LEDs will flash and the lock will take the power from the PP3 battery. We sell a battery override tool to make this step a little easier. 
  3. Now enter a valid Master Code to open the lock.
  4. Once access has been gained the lock can be removed from the door and new batteries fitted.


The Master Code will always erase the User Code, to unlock when the lock is locked with a User Code a Technican Code will need to be used. The Technician Code can be used to open lockers without forgetting the User Code and leaving the locker vulnerable. How to program a Technician Code can be found in the lock's programming and operating instructions. 

Copies of all KitLock programming guides can be found here.


The lock is programmed into Public Use, if you want the lock to unlock when you input your User Code and then re-lock after 4 seconds, you will need to program the lock into the Private Use Function using program 26.  The lock will then go into Private Use with a default User Code of 2244.

See your programming and operation instructions for more detail.


The lock must be programmed quickly without hesitating, if you pause for a second the lock will reset and you will need to start the process again. Writing the sequence down for reference can make it easier to input. Try again without pausing and you will be able to make the required change.


The batteries are running low and require replacement as soon as possible. Remove the top fixing bolt on the inside of the door and slide the top of the lock over to the side. Remove the batteries and fit two new AAA cells.


The batteries are almost exhausted and the lock is losing functionality with insufficient power to drive the motor. To gain access you will need a 9v PP3 battery and to wait until the batteries have been completely exhausted before the battery override can be accepted.

  1. Position the positive terminal of the battery against the red LED and the negative terminal against the blue LED.
  2. Once contact has been made, the blue and red LEDs will flash and the lock will take the power from the PP3 battery. We sell a battery override tool to make this step a little easier. 
  3. Now enter a valid Master Code to open the lock.
  4. Once access has been gained the lock can be removed from the door and new batteries fitted.


A NetCode can start on the hour with a minimum duration of an hour time period. Should you require it, there is an option to have a 15 minute grace period on either end of it's access period.


Important Notes: Please note you cannot run two modes at the same time (standard mode is the only exception). This means you cannot have Standard mode and Rental mode enabled at the same time. If you have generated a standard NetCode and then change the mode to Rental and sync the app, the standard NetCode will no longer function as that mode is no longer available.

If you change the NetCode mode on the lock, this will only change the NetCode mode. This means the Master Code, settings and any existing phone clients or code clients will not be affected.

By changing the mode via the lock (KL1000 NetCode), this will not affect NetCode generation via the Codelocks Connect Portal, the customer service team who are using the portal need to be made aware of any mode changes. This is so they do not issue a Standard code when Rental mode is enabled.

Standard Mode (Multi Use)

This mode allows you to create a NetCode lasting between 1 to 12 hours, and 1 to 7 days.  You can use this code multiple times within the set duration.

Standard Mode (Single Use)

This mode allows you to create a NetCode lasting between 1 to 12 hours, and 1 to 7 days. You can only use this code once within the set duration.

Rental 1 - 21 Day (ACC)

This mode allows you to create a NetCode duration between 1 and 21 days which can be used multiple times. The NetCode must be validated, this is done by inputting the NetCode into the lock within 24 hours of its set start date.

Pre 2018 Models ONLY: A NetCode with a 1 day duration can start on the hour, for example from 17:00 Monday to 17:00 Tuesday. However, all other durations (2 days and upwards) must start at 00:00 on the first day of its duration.

Rental Max 365 Days (URM)

This mode allows you to create a NetCode which will last for 365 days and can be used multiple times. This feature includes Block Previous NetCode by default, this withdraws access from the previous NetCode used so only one NetCode is usable at a time. It also allows you to set your own validation period which can be anywhere between 1 to 12 hours, or 1 to 7 days.

End Date Mode (KL1060C2 Only)

This mode will allow you to set a NetCode to finish at a specific time and date within the next 365 days.

Note: It is not possible to use both this mode and another (e.g. ACC mode), only one-hour standard multi use can be used in conjunction with this.

Note: Just as with Rental 365 mode, the Block Previous NetCode feature is turned on by default.

24 Hour Mode (KL1060C2 Only)

Use this mode to set a NetCode to start at any hour of the day with a duration of 24 hours.


This is because the lock is currently not set up to allow NetCode access. To fix this, go into the lock's settings in the App, tick the box next to NetCode and then synchronise the lock to implement the changes.


This is a feature that needs to be activated on the lock before it can be used. To activate this, go into the lock's settings in the App, go to NetCode® Features then Modes and select URM mode before synchronising the lock to implement the changes.
