Cylinder locks for self storage units
Most facilities start with whatever locks were available. A few years later nobody can say which key opens which unit. A standard cylinder and a documented key plan fixes that permanently — and it is the only way a replacement cylinder still matches the keys your tenants hold.
Choose your configuration
Four decisions shape this order. Pick what applies and we will confirm the rest with a sample.
- Size
- 19 mm · 17 mm
Measure across the cylinder face, or send a photo with a ruler. - Key system
- Keyed alike · keyed different · master key · manager key
The family that makes a facility key plan possible. - Material
- Solid brass
Brass shell and core for corrosion resistance and key feel. - Suits
- Replacing mixed cylinders with one standard
Standardising an existing site without replacing doors. - Documentation
- Key plan per site
So a cylinder ordered in three years still matches the original keys.

No model references, prices, stock levels or sales figures are published here. Where a parameter depends on the specific model, we confirm it for the model you order rather than describing the whole family.
Fit and compatibility
- Cylinder size is the parameter that decides fit — 19 mm and 17 mm are the sizes we supply.
- If you are unsure of the size, measure across the cylinder face or send a photo with a ruler.
- Where the door has a hasp or padlock eye instead of a cylinder cut-out, use a padlock rather than a cylinder.
- We confirm fit with a physical sample so you are not guessing from a drawing.
Fit confirmed by sample, not by drawing. Send a door photo, the cylinder size or the mounting dimensions and we will send a physical sample before you commit to a quantity.
Ordering information
The commercial terms for this family. They are confirmed with the quotation, so a re-order two years from now carries the same conditions rather than a new set.
- MOQ
- From 500 pcs
Heavy customization — a new mold, a special key system, printed blister cards — may require more. The exact figure is confirmed with your quotation. - Samples
- From 5 days
Sent so you can check fit and finish on your own door before committing to a quantity. - Batch production
- Around 30 days after spec and artwork confirmation
Peak periods such as Chinese New Year are flagged when you order. - Delivery terms
- EXW · FOB · CIF · CFR · DDP
More than one term can be quoted so you can compare what the goods cost against what the freight and duties cost. - Payment
- T/T · L/C · Credit card
A first order normally runs on a deposit with the balance against the documents or on shipment. - Documentation
- Spec sheet, inspection record, packing list, pre-shipment photos
Test records are issued per model and per finish, and are available for the model you order.
Tell us the quantity, the door type and the destination country and we will quote the configuration rather than a list price.
Options and customization
What can change without changing the product's identity.
Key plan
Tell us the unit count per site, whether tenant keys must be unique, and how many manager keys you need. We return a key plan with the quotation.
Manager keys
A manager key can open every unit on one site, or every site in a group, depending on the keying schedule.
Overlock integration
If a manager key also operates overlock hardware for vacant units, both are planned on the same keying schedule.
Re-order continuity
Dimensions, finish and keying are stored against your specification so a later order matches what is already installed.

Buyer questions
How do I know which cylinder size I need?
Measure across the cylinder face. If that is not practical, send a photo of the cylinder with a ruler beside it — that is usually enough for us to identify the size and confirm it with a sample.
Can one manager key open every unit?
Yes. We build master-key and manager-key systems where each tenant key opens only its own unit and a manager key opens every unit on a site, or every site in a group. Tell us how many units and how many manager keys.
Can you match cylinders to doors we already have?
Yes — that is the main reason buyers come to this family. Send the door type, the current cylinder size or a photo, and we confirm the match with a physical sample.
What happens when a tenant key is lost?
It depends on your keying structure. With keyed-different units, only that unit is affected. With keyed-alike groups, a lost key exposes the whole group. Decide the policy before production, because keying cannot be changed afterwards.
Can you keep our keying on file for re-orders?
Yes. The key plan and cylinder specification are recorded against your account, so a re-order two years later still matches the keys in circulation.
