Safe Ventures Union Decoder

The Union BS Decode System is a professional decoding kit designed to quickly identify lever codes in Union BS‑style locks and many Yale and Chubb variants, including lower‑grade security versions. The system employs an impressioning approach using a specially prepared key to produce readable profiles of the lever bellies. These readings are then used to assemble a variable makeup key for opening. Because the technique produces clear code indications, the method is accessible to technicians with relatively little specialised training.

This kit is particularly useful for locksmiths and service engineers who need a rapid, non‑destructive way to determine lock codes in the field. It’s compact and workflow‑oriented for efficient on‑site use.
