Product-level certification
BSI wording is useful when it is tied to the exact marked product.
BSI Kitemark certification gives customers a recognised way to check product claims, but it must be used precisely. For Lock & Key customers, the important question is which Yale, VBH/greenteQ, lock, cylinder, nightlatch, or door/window hardware item carries the mark and whether it suits the opening being secured.
Yale ranges
Where Yale products reference BSI, Kitemark, BS3621, TS007, or other standards, we connect the standard to the exact lock, cylinder, or door hardware being specified.
VBH and greenteQ hardware
For Protec10 and related VBH/greenteQ support, BSI-aware advice sits alongside compatibility checks, fitting conditions, and aftercare requirements.
Other marked products
The same rule applies beyond those ranges: a product marking is useful evidence only when it belongs to the actual item and the installation preserves the intended security level.
How we use BSI wording
We make the claim specific before customers rely on it.
Identify the product
Confirm the brand, model, range, visible marking, datasheet, or certificate route before treating BSI wording as evidence.
Match the standard to the door
BS3621, TS007, PAS, Kitemark, Secured by Design, and insurer wording can point to different hardware decisions.
Check the fitted result
A certified product can still be undermined by poor sizing, weak furniture, dropped doors, loose keeps, or unsuitable escape arrangements.
Keep the record
Where the purchase relates to insurance, landlord records, or compliance, keep photos, paperwork, and product references together.
