Lockey LOC28-KNOB-JB – Frequently Asked Questions

1) I broke the knob on my Lockey keyless lock, do I have to buy a whole new lock?
No. The 28-KNOB is sold as a standalone replacement for the knob on Lockey mechanical keyless combination locks in the 2830, 2835, 2985, 2930, 3830 and 3835 series, including the DC versions. Swap the trim and keep the existing lock body and code. For a property manager with a run of Lockey units, that means one damaged handle is a parts order, not a re-key and re-install.
2) Will a Lockey 28-KNOB fit a Codelocks or BEST keyless lock?
No. The 28-KNOB is Lockey trim and fits only the Lockey 2830, 2835, 2985, 2930, 3830 and 3835 series. It will not mount to a Codelocks CL250, CL510/CL515 or CL610/CL615 tubular latch lock, or to a BEST 8T Series tubular deadbolt. Those are different brands with their own trim; if the lock body on the door is Codelocks or BEST, the replacement handle has to come from that maker's own parts.
3) Can a Kwikset Halifax dummy lever trim be used to replace a worn Lockey 28-KNOB?
No. The Kwikset KWI-968HFLRDT Halifax lever with round rose and the KWI-968HFLSQT square rose version are dummy function trim, meaning they are fixed handles with no internal mechanism, and they are built to mount to a Kwikset handleset rather than to a Lockey chassis. The Lockey 28-KNOB is lock trim that replaces the knob or lever component on 2830/2830DC, 2835/2835DC, 2985/2985DC, 2930/2930DC, 3830/3830DC and 3835/3835DC keyless combination locks and turns the lock's retracting mechanism. If the intent is to restore a working Lockey combination lock, the 28-KNOB is the part; the Kwikset dummy trims cover a different job entirely, dressing an inactive leaf.
4) The Lockey lock body itself is worn out, not just the knob. What keyless lock should I put on the door instead?
When the chassis is the problem rather than the trim, the Codelocks CL510 and CL515 tubular latchbolt back-to-back from the CL500 Series and the CL610 and CL615 tubular latchbolt back-to-back from the CL600 Series are both rated heavy duty and give keyless code entry on both faces of the door. If key override is wanted alongside the code, the Codelocks CL250 tubular latch from the CL200 Series carries a key override cylinder. The Lockey 28-KNOB only makes sense when the existing Lockey mechanical keyless combination lock is otherwise sound and the knob or lever is what failed.
5) What finishes does the Lockey 28-KNOB come in so I can match my existing hardware?
Eight finishes: Antique Brass (AB), Bright Brass (BB), Bright Chrome (BC), Jet Black (JB), Marine Grade (MG), Oil-Rubbed Bronze (OIL), Satin Chrome (SC), and White (WH). That is the full range, so order the code that matches the lock body already on the door rather than guessing from a photo. Finish codes on Lockey locks are called out the same way, which makes matching a partial replacement straightforward.
6) Which Lockey knob finish should I use on a gate or a poolside door near salt air?
Marine Grade. Of the eight finishes offered on the 28-KNOB, Marine Grade is the one intended for coastal and high-moisture exposure where corrosion resistance matters. On an inland interior opening any of the other seven, including Jet Black or Satin Chrome, will do the job; the corrosion-resistant option only earns its place outdoors or in a wet environment such as a pool enclosure or a wash-down area.
7) Can the Lockey 28-KNOB be used to convert a lever model over to a knob?
Yes. It is listed as a replacement for the knob or lever component across the 2830, 2835, 2985, 2930, 3830 and 3835 series, so on those locks it takes the place of the lever trim with a knob. Worth thinking twice about on an accessible route: a knob requires grasping and twisting where a lever does not, so on openings that need lever-operable hardware, replace the lever with a lever.
8) Is the Lockey 28-KNOB a complete lockset or just the outside handle?
It is trim only, a knob component for an existing Lockey mechanical keyless combination lock. There is no latch, no combination chamber and no strike in the box. Order it when the lock is installed and functioning and the handle is damaged, worn, or the wrong finish. If you are hardware for a new opening, you need a full keyless lockset instead.
9) Is there a simpler non-keyed option than rebuilding a Lockey combination lock on a low-traffic interior door?
The BEST 8T Series closet function non-keyed tubular deadbolt uses a blank plate on the outside and a thumbturn on the inside and fits a 1-3/4 inch door, so it secures from inside with no code and no key to manage. That suits storage and closet openings where nobody needs to gain entry from the corridor side. The Lockey 28-KNOB is the opposite case: it keeps an existing Lockey mechanical keyless combination lock in service on an opening where coded entry from the outside is still required, and it is specified for commercial use.
10) What is the difference between the Codelocks CL250 and a Lockey lock fitted with a 28-KNOB when a master key is needed?
The Codelocks CL250 tubular latch from the CL200 Series includes a key override, so a property manager or maintenance lead can open the door with a cylinder key when a code is forgotten or an occupant is locked out. The Lockey 28-KNOB is trim, not a lock: it restores the knob or lever on 2830/2830DC, 2835/2835DC, 2985/2985DC, 2930/2930DC, 3830/3830DC and 3835/3835DC mechanical keyless combination locks and does not add a key cylinder to an opening that did not already have one. Where a key path is part of the facility standard, the CL250 is the lock to spec; where the existing Lockey units already meet the standard, the 28-KNOB keeps them running.
11) For a coastal building, is a Codelocks back-to-back lock or a Lockey knob replacement the better fix for corroded hardware?
It depends on which part corroded. If the lock mechanism still works and only the exterior knob has degraded, the Lockey 28-KNOB is offered in a Marine Grade finish alongside Antique Brass, Bright Brass, Bright Chrome, Jet Black, Oil-Rubbed Bronze, Satin Chrome and White, and Marine Grade is intended for coastal or high-moisture exposure. If the whole lock needs to come off the door, the Codelocks CL510 and CL515 back-to-back from the CL500 Series and the CL610 and CL615 back-to-back from the CL600 Series are heavy duty tubular latchbolt units that replace the complete assembly.
12) Is the Lockey 28-KNOB rated for commercial traffic or is it a residential part?
Commercial. The 28-KNOB is classed as commercial door hardware and is the replacement trim used on Lockey keyless combination locks in offices, schools, healthcare and institutional buildings, retail, warehouses, multi-tenant residential and government facilities. That matters for MRO buyers standardizing a building: the same part number in the same finish covers every Lockey opening in the six compatible series.
13) Does the Lockey 28-KNOB work on passage function locks as well as combination ones?
It does. The knob is listed as working with both combination and passage function models across the compatible Lockey series, so a lock set up as always-unlocked passage takes the same trim as one running a code. The DC (double combination) versions in the 2830DC, 2835DC, 2985DC, 2930DC, 3830DC and 3835DC line are covered as well.
