Lockwood deadbolts buying guide
Every deadbolt in this collection is the Lockwood Paradigm 005 double cylinder deadbolt, sold with a round rose or a square rose and in several finishes. That narrows the choice to a few questions: which rose, which finish, if the door and frame suit a double cylinder lock, and if the lock replaces an existing deadbolt or goes into a door that has none. This guide covers what the 005 does, how its three modes work, what fit, keys and standards apply, how a double cylinder behaves in an emergency, and what to check on the door before you order. For other deadbolts on the site, see deadbolts and Lane deadbolts.
What a deadbolt does
A deadlock bolt moves only with a key or a thumb turn and does not retract when the handle is pressed. A solid, square-ended bolt resists the card and shimming attacks that can push back a spring latch. Firewize draws the same line from the other side: a deadbolt is operated by hand, while a deadlatch locks by itself when the door closes. A deadbolt works alongside the handle and does not replace it. Knob or lever locks are not suitable as the primary door lock, and the deadbolt is the part that extends into the frame. The lever sets that sit beside a deadbolt are on entry door lock sets, exterior door levers and Lockwood door levers.
The 005 and its three modes
The 005 is a multi-mode slimline deadbolt. A status indicator on the inside, called LockAlert, shows which of three modes the lock is in. In secure mode the door is locked from the inside and the outside, which is the setting for when nobody is home. In safety mode it is locked from the outside and free to exit from the inside. In passage mode it is free to enter from the outside and free to exit from the inside.
The key controls the mode. A turn of the key gives safety mode, and turning it further selects secure mode, a feature called DualSelect. SafetyRelease automatically unlocks the internal knob when the door is entered by key from outside, which minimises the risk of being locked in. Both features answer the usual objection to a double cylinder lock, covered next.
Single or double cylinder
The single cylinder lock, keyed outside with a thumb turn inside, is the most common arrangement. A double cylinder needs a key on both sides, which suits a door with glass nearby, because someone who breaks the glass cannot reach a thumb turn. The trade-off is simple. With a single cylinder you can leave quickly, but someone who breaks a nearby window can reach the turn. A double cylinder closes that gap, but in an emergency you need the key to get out. Keep a spare key near the door where an intruder cannot reach it, and remember that some areas restrict double cylinders for fire safety, so local rules matter.
The 005 here is a double cylinder lock, and the modes are how it manages the exit problem. In safety mode the inside is free, so a household can leave the lock there while people are home. Secure mode is for an empty house, when the key trade-off applies. Double barrel deadbolts need a key on both sides, which is a fire risk on emergency exits, while a single barrel has an inside twist knob. A deadbolt is for use at night or when you are out, which matches how the 005's secure and safety modes divide. Single cylinder deadbolts are on deadbolts and Lane deadbolts.
Security rating, keys and picking
The Australian standard for locksets, AS 4145, tests cylinder security, bolt strength, lock body strength and key control, with grades from 1 to 4 and above. The 005 carries four ratings under AS 4145.2-2008: SL8 for security, D8 for durability, C6 for corrosion and K5 for key security. Joined, the rating reads SL8D8C6K5. Compare locks on those four figures, and ask a locksmith how they read for your door.
The lock is bump and pick resistant, under the name Kinetic Defence. The cylinder is a 5 pin tumbler with a brass cylinder and brass barrel, and the bolt is a cut resistant stainless steel bolt. The cylinder is the most targeted part of a lock, so those cylinder features are the ones to weigh. Neither the product pages nor this page claim that the lock cannot be picked.
Each lock comes with two keys. The lock is supplied individually keyed with 78,000 key combinations and can be keyed alike to other Lockwood door locks. Keyed alike, project keyed and restricted profile options exist, so contact the maker's customer service about keying. Lockwood locks can be keyed to controlled or special systems, including legally protected keys that guard against unauthorised duplication and master key systems. If you want one key for several doors, ask about that before ordering.
Choosing a grade of lock
The rating is a way to compare, and the right level depends on the door. Grade 2 or 3 suits most homes, which is a view and not a rule. Some insurance policies specify minimum lock standards, so check yours before you choose. That grade scale and the SL, D, C and K figures on the 005 sheets are two different ways of rating a lock, and this page does not convert one into the other. The Symmetry deadbolts are standard security products, to be fitted with a key in knob or key in lever lockset, and the 005 is the premium security solution in the range. Ask a locksmith which suits each door.
Fitting to your door
The 005 is designed to retrofit. It replaces an existing deadbolt, fits a 54mm hole, has a 60 to 70mm adjustable backset and suits doors 32 to 48mm thick. Doors 32 to 36mm thick need a spacer ring, and it is included. The box includes a strike with a concealed crossgrain doorframe strengthening screw. A counterbalance bolt spreads the load between the door and the frame.
A new door needs more. The Lockwood deadbolts category page explains that a borelock deadbolt is installed by boring two holes into the door, set perpendicular to each other. The bolt has to enter the frame fully and the screws have to reach solid timber. Correct alignment and hinge notching are difficult, so use an accredited, licensed and insured locksmith for lock work. Exterior locks also need solid doors and steel frames. A thin frame or a hollow door limits what any lock can do, so check the frame before you spend on the lock.
Round or square rose
The rose is the plate behind the knob and the key cylinder, and it is the part you see. The 005 comes with a round rose or a square rose, and the lock works the same way in both. The finish range differs. The finishes are satin chrome pearl, satin chrome brushed and chrome plate, with Everbrass and satin stainless steel for the round rose only. This collection also includes matte black on both roses. Match the rose to the other hardware on the door.
Materials, finishes and care
The body is high purity zinc alloy. The satin stainless steel version has a 304 grade satin stainless steel rose, turn knob and trim. The 005 passed a neutral salt spray test under AS 2332.3.1:2001, and the stainless steel version offers greater corrosion resistance. On finishes, chrome shows fingerprints and water spots more readily than brushed finishes, and matte black gives contrast on white doors but can look too dark in a low-light room. Coordinate finishes with the rest of the hardware, and clean with a soft damp cloth, with no abrasive or acidic cleaners, wiping brushed finishes along the grain.
The finish pages for the door handles that sit beside a deadbolt are matte black, chrome, brass and stainless steel.
Where the 005 sits among Lockwood deadbolts
The 005 sits beside several other Lockwood products. The latching Paradigm 005 has a holdback function that keeps the latch retracted when required. The Symmetry deadbolts are general purpose, standard security products that should be fitted with a key in knob or key in lever lockset for added safety. The Symmetry 7106 is single cylinder and the 7107 is double cylinder, with a 31 to 45mm door range, and both suit left or right hand doors. The Symmetry 7107 comes in the stainless steel collection on stainless steel door handles and hardware.
The Paradigm pull handle locksets take the 005 features into a pull handle. Lockwood also makes 304 grade stainless steel pull handles with a 600mm external handle and a 500mm internal handle, 30mm wide, for doors 32 to 48mm thick, in a deadbolt version, a deadlatch version and a dummy handle for double doors. The deadbolt version includes door magnets to hold the door in passage mode. The deadlatch version is tested up to 2 hours on fire assemblies under AS 1905.1-2005, with an SL7 security rating. Pull handle locksets are on entrance pull sets.
Questions that come up about this lock
Are Lockwood deadbolts good? The facts to judge by are the AS 4145.2-2008 ratings above, a 5 pin tumbler cylinder, a cut resistant stainless steel bolt, a strike with a frame strengthening screw and a salt spray test. A rating is not the same as a promise of security, and the frame and door decide how much of it you get. Are they hard to pick? The lock is bump and pick resistant. This page makes no stronger claim, and the cylinder is the most targeted part of a lock. Are they made in Australia? The 005 is designed in Australia.
Planning the door
A secure entry door is a set of parts working together: the deadbolt, the handle or pull, the hinges and the frame. Give side, rear and garage doors the same care as the front. Make a door-by-door list of room, function and finish, with the extras each door needs. For a deadbolt door, the extras are the lever or pull, the hinges and a door stop, from door handles, hinges and door stops. If the door needs no lock, passage and privacy handles do that job, and for a keypad or app lock see smart door locks. The wider range is on door hardware.
Questions about Lockwood deadbolts
Are Lockwood deadbolts hard to pick?
The 005 is bump and pick resistant, with a five pin tumbler, a brass cylinder and barrel, and a cut-resistant stainless steel bolt. It does not claim an unpickable lock. The rating under AS 4145.2-2008 is SL8D8C6K5. That standard tests cylinder security, bolt strength, lock body strength and key control, so the rating is a way to compare locks that are tested the same way.
Which doors should have a deadbolt?
A deadbolt is a second locking point on an entry door, separate from the handle latch. It suits front entrance doors, and it also suits side and back doors, especially those without windows nearby. A deadbolt does not retract when the handle is pressed, and it is operated by hand, which separates it from a deadlatch that locks by itself when the door closes. Home security advice is that a knob or lever lock should not be the primary lock on its own, so a deadbolt beside a lever set is the usual pairing.
Single or double cylinder for a door with glass?
A single cylinder has a key outside and a thumb turn inside. It is the most common choice for residential front doors, and it lets you leave quickly without a key. A double cylinder needs a key on both sides, which is the suggested option where there are glass panels near the door, because someone could break the glass and reach in to turn a thumb turn. The trade-off is egress: with a double cylinder you need a key to get out in an emergency, so think about children and about whether the door is a main exit.
The three modes and what the indicator shows
The 005 works in three modes, and the LockAlert indicator shows the current mode at a glance. In Secure mode the door is locked from inside and outside. In Safety mode it is locked from outside and free to exit from inside. In Passage mode it is free to enter and exit. DualSelect lets you choose between Safety and Secure with the key: turn once for Safety, and further for Secure. SafetyRelease unlocks the inside knob when the door is entered, which reduces the risk of being locked in.
Every product page here is the 005 double cylinder deadbolt, so the choice on this page is finish and rose shape rather than model. Decide those two things first, then check your door thickness against the 32 to 48mm range before you order.
Finishes and rose shapes
The 005 comes with a round or a square rose. The finishes listed are matte black, satin stainless steel on the round rose, brushed satin chrome, chrome plate, everbrass on the round rose, and satin chrome pearl. Choose the rose shape to match the lever set on the same door, and choose the finish to match the other hardware you can see.
A checklist before you order
Five checks cover most orders. Confirm the door thickness is 32 to 48mm, and remember that a 32 to 36mm door needs the spacer ring, which is included. Check the hole is 54mm if you are replacing an existing deadbolt. Set the backset between 60 and 70mm, since the stainless steel bolt adjusts across that range. Decide on single or double cylinder using the glass and egress points above. Last, check that the bolt will fully enter the frame and that the screws reach solid timber, because a deadbolt is only as strong as the frame it locks into.
Plan the key arrangement before the lock goes in. The 005 can be keyed alike to other Lockwood door locks, so if the house already has Lockwood locks on other doors, decide now if one key should open all of them, and say so when you order, since keying cannot easily be changed after the lock is fitted. Keep every key in a known place, label the spares, and give one to someone you trust. If the door leads onto a garage or a back entry, think about who in the household uses it and how they will get out in an emergency, and choose the cylinder type with that in mind.
Fit the deadbolt before you hang the door furniture around it. Mark and drill the bolt hole and the cylinder hole, check that the bolt throws freely into the strike, and then fit the handle. This order makes it easier to adjust the lock if the bolt rubs, and it keeps the plates square to each other. Test the bolt from both sides with the door open and closed before you leave the job.
