How do I determine the handing of a door?

The handing of a door is always determined by facing the exterior of a door.

When ordering a handed product, specify LH or RH. Not all products are handed; only specify handing when required.

What can I use to clean my Lockwood product?


Do not use solvents or abrasive cleaners on any components as this will destroy the protective clearcoat finish and void the guarantee.
Please use a water dampened, soft cloth to remove fingerprints.

A mild soap solution applied with a soft cloth will remove oil or accumulated dirt build-up.

Note: Avoid products that state on the label that they remove tarnish and rust or that they contain acids or caustic agents.

001 Deadlatch | 355 Deadlock


When I put the key in the outside cylinder it is free spinning without locking the lock.
The tailpiece on the outside cylinder has been cut to short or is not connected to the hub.

The lock will not deadlock or function properly.
The tailpiece on the outside cylinder has been cut to long as is protruding into and interfering with the lock mechanism.

The safety release on the 001 deadlatch is not operating properly.
If the lock has been re-keyed, the cam on the back of the inside cylinder (which operates the safety release) has not been reset correctly the safety release feature will not work.

I have an outward opening door, can the 001 deadlatch be fitted in this situation.
Yes, but if the door is outward opening or metal frame you will need to order the version of the 001 to suit these applications.

I lock the 355 deadlock from outside with the key, but the inside does not deadlock.
The deadlocking of the 355 is a very manual process, as the internal and external locking operate independently.

Commercial Door Furniture


Fixing screws tight, but furniture loose on door
Furniture screws too long

Furniture screws difficult to tighten
Burrs on screws – Must de-burr screws when cutting to length.

Turn snib difficult to operate
Tail bar not cut to correct length or turn snib misaligned on door.

Can I change the door furniture handing on the Securafix products?
Changing the handing on the plate moves the hex nuts to the wrong side of the door. The furniture fixing will not clutch when fitting and will clutch when loosening.

Why can I not use the entire selection of lever handles on the narrow stile furniture?
The clearance on the narrow stile will not allow some levers to function.

Commercial KNK/KNL


What is the baffle for in the 930 series locks?
The baffle helps to achieve correct alignment between the lock and latch, minimising installation issues.

530 series lock loose on door
Loose fixing screws – possibly loosened over time/use – maintenance, or:
Incorrect door preparation, and screws left loose to compensate/permit operation of the lock

Knobs/levers binding

  • Incorrect door preparation
  • Lock damaged in heavy/rough use – this is often a result of the product being used in a heavy-use commercial environment, which it is not designed for
  • Heavy operation of the external handle on the 530/930 combination sets – this is a consequence of the design of the lock, and should not be specified when difficulty of operation could be an issue. The CML will achieve these functions and maintain ease of operation
Commercial Mortice Locks (3572 & 3582 series)


Lock will not lock when key is operated
Check cam on cylinder is correct. Is the hub setting correct?

Woodchips or metal filings in lock case
Locks are supplied with cylinder covers fitted. If these are removed and the lock exposed to debris, problems can occur.

Difficulty in locking a lock set to anti-lock-out function
Incorrect alignment of the strike plate, preventing the latch from fully throwing will make it difficult or impossible to lock the lock.

Digital Locksets


Turn knob difficult to operate
The alignment or installation of code pad is incorrect or the connecting bar has not been cut to the correct length.

Turn knob doesn’t open when you enter your code
The ‘C’ button has not been entered at the start of the code.

Problems that contribute to premature wear of the code pad mechanism

  • Not pushing the “C” button at the start of the code
  • Pushing multiple buttons at the same time (e.g. top 4 buttons of code pad)
  • Pushing multiple buttons while trying to operate the turn knob
Door Closers


The door is closing too fast or too slow
Adjust the closing and latching speed valves to achieve a suitable door closing speed.

The door closer is not latching the lock properly

  1. First, ensure the door is swinging and latching freely with the door closer disconnected from the door.
  2. Check if the door closer is the correct power for the door
  3. Check if the door closer is installed correctly
  4. Check if the door closer is adjusted correctly (power, closing, latching)

My parallel arm door closer is lacking power

Need to factor in power loss of approximately 20% when using parallel arm configuration. Additionally, arm must be pre-loaded per the instructions.

My slide rail door closer will not let the door open all the way.
Slide rail door closers have limitations on how far the door may open. This should be assessed prior to installation of the door closer, for suitability of the closer to the door. A door stop should be used to prevent opening the door past the closers’ limit.

Does temperature affect the hydraulic valve settings?
Yes, it can and its affect may be noticeable at extremes of heat and cold.

Electro-Mechanical Products


Does “fail secure” mean that people will be locked in if the power is cut?
No, not necessarily. Products should be configured in a way to ensure safety and security.

  • Example 1: Electric mortice lock can be set as fail secure, with vestibule function.
    This means that the inside handle is always free, and the outside handle will be locked when there is no power to the lock.
  • Example 2: Electric strike can be set as fail secure and used with a vestibule function lock.
    The lock will provide the egress and the strike will remain secure when there is no power to it.

Why are mag-locks only available in fail-safe?
The electro-magnet requires power to energise the magnet.

Can electro-mechanical locks be fitted to glass doors?
Yes, this is a rapidly growing area and there are many options available, using patch fittings and adhesives as alternatives for mounting. There is a product catalogue dedicated to this area, called “Electro-Mechanical Locks for Glass Doors”

I have a door with an electric strike, when the strike is activated, the door needs to be “rattled” to get it to open.
This is usually a result of the strike being subject to pre-load conditions. When the door is rattled, it briefly removes the pre-load, allowing the strike to release.

I have a door with an electro-magnetic lock, it sometimes releases just from trying to open the door firmly.
Electro-magnetic locks can suffer from a significant reduction in holding force if the lock and armature become misaligned. A mag lock should not be the only item securing a door.

Internal Door Furniture


Fixing screws tight, but furniture loose on door
Furniture screws too long.

Furniture screws difficult to tighten
Burrs on screws – Must de-burr screws when cutting to length.

The holes previously drilled in the door are too small for door furniture I purchased
In a retrofit situation, if the previous door furniture is old often the holes drilled for the furniture are not suited to the new furniture and may need modification.

The backset for the door furniture is not the same as previous door furniture
In a retrofit situation, if the previous door furniture is old it may have a different backset - Many of the new door furniture products have adjustable backsets built into the latches.

How does the emergency release function on the privacy sets work?
There will be a release, turn button or other device built into the door furniture to allow access in the event of an emergency.



What stops other people from duplicating someone else’s restricted keys?
Restricted keys rely on legal protection from Patents and Design Registrations to prevent others from manufacturing the keyblanks. Before anyone is given access to the keyblanks they must enter a distribution agreement which does not allow them to cut keys without proper authorisation.

How long does a keying system last?
The intellectual property protection can last up to 20 years from lodgement. In practice, most mechanical keying systems are due for replacement after 5-7 years in use; this is a result of changes to requirements and losing or tracking of keys whereabouts.

Nexion Keyless Entry Lockset


Will I be locked out if the batteries go flat on my Nexion Keyless lockset?
No, the lockset can be operated with the standard keys provided.

Can I use rechargeable or Lithium batteries in my Nexion Keyless entry lockset?
No, rechargeable & lithium batteries do not have enough voltage force to throw the locking bolt.

Is there hard-wiring required for the Nexion Keyless entry lockset?
No, the Nexion Keyless entry lockset runs off 4 good quality AA alkaline batteries.

Can I purchase a mechanical Nexion and then add the electronic parts to it in the future?
No, you can replace the Mechanical with the Keyless, but you can not just add electronic components to the Mechanical version.

If I lose one of the remotes to my Nexion Keyless Lockset, can someone get in easily?
No, you can quickly re-program the Nexion and the lost remote will no longer operate the lock.

What is the range of the remote control?
Approximately 3 metres depending on the environment and battery strength, for example if there is a metal screen door installed in front of lockset, the range will be reduced.

The remotes will not operate my Nexion Keyless lockset.
Either your batteries are flat or incorrectly fitted. The remotes may not have been programmed in properly or it could be an alignment or installation error.

How easy is the Nexion to fit to a door?
Preparing the door for fitting the Nexion is aided through the use of a metal drilling template which is provided in each pack and when used in conjunction with the supplied instructions ensures that all holes are correctly placed. Handing of the lockset is also easily changed with no disassembly of the lockset required.

Can the Nexion be fitted in a new installation only?
No, the Nexion can be retro-fitted over many standard locksets.

Onyx Sliding Door Deadlock


The locking beaks do not line up with the striker.
The reasons for this happening are:

  • Fitting template has not been followed correctly and striker height needs adjustment.
  • Fitting template has not been followed correctly and holes for lock body are out of position.
  • Because of the different types of door sections in both timber & aluminium, there may be a requirement for an extra width striker or a striker or lock body packer.

The key and internal turn snib are hard to operate.
When fitting the lock rather than using the recommended 10mm drill bit when drilling holes for the lock body, an undersize hole has been drilled. This will cause the cylinder turn bar to bind on edges of the drill hole.

I have fitted the Onyx from the display pack and it appears to be working correctly, but there are many parts left over.
There are extra parts provided in the retail display pack because of all the different door sections and configurations in the marketplace.

Padlocks & Padlock accessories


What can I do about problems with padlocks corroding?
Select a grade 4 corrosion rated padlock – for the harshest of applications, such as marine use, use the stainless steel bodied and shackled marine grade padlocks.

The key is difficult to operate in my padlock.
As padlocks are often in exposed positions, lubrication of the cylinder may be required more often than with other locks.

My padlock case was cut with a hacksaw to open the padlock.
Brass (and stainless steel) padlocks are susceptible to this, for highest security, use a padlock with a hardened steel case.

Someone has unscrewed the locking plate on my factory gate and escaped with my goods.
All padlock accessories are supplied with suitable fixings for normal installations, it is important that they are used to maximise security.

Panic Exit Devices


How do I know when I need to use a panic exit device instead of a lever handle?
The general guide is that if more than 100 people access the room, a panic exit device will likely be needed, although the BCA does provide for some exemptions.

Can I use a panic exit device instead of a lever handle?

Are all doors with panic exit devices fire doors?
Not necessarily, the requirements are from different parts of the BCA.

9000 series

Can the panic exit bar be matched to my existing door hardware for external access?
Yes, the 9500 series is matched to a mortice lock, which can use external 1800 & 2800 series door furniture to match with existing commercial hardware.

5000 series

The cross bar on my 5000 series push bar is being damaged by rough use.
The 9000 series are far more resistant to abuse, as the touch bar is fully supported across the door.

Paradigm Deadbolt


Why is the bolt shorter on the Paradigm in comparison with other deadbolts?
The Paradigm bolt is actually longer than the bolt on most deadbolts. To achieve the highest security levels and strength half the bolt is in the door and half is in the frame

When I am using the turn knob or the key the bolt is not throwing.
The bolt tailpiece has not engaged with the lock mechanism.

Do I need to fit the door frame strengthener on the Paradigm?
It can be fitted without the door frame strengthener, but you will compromise your security on the lock and it may not meet level S3 of the door lock standards.

Do I need to fit the anti-rotation pins when I fit my Paradigm?
Yes, if they are not fitted the lock if forced may rotate, causing damage and possibly unlock.

The Paradigm is not operating properly.
Check operation with the door open – if OK, adjust strike position on frame. Alternatively, check the correct length tailpiece has been used and that the lock has been correctly aligned during installation.
