Hand Punch Master Key – Legacy Replacement Part
The Hand Punch Master Key, also known as the Model 1003 key, was a
universal replacement key used on a variety of hand punch time clock
systems. While this part has been discontinued and inventory is no
longer available from stock, understanding its role helps you identify
the right solution for older mechanical clocks still in service. :contentReference[oaicite:4]{index=4}
Hand punch time clocks were an early method for tracking employee work
hours. They relied on mechanical action and a physical ribbon or
stamping mechanism to record punches. To perform maintenance such as
ribbon changes or internal adjustments, a key was required to open the
clock’s casing.
Common Usage of the 1003 Key
The 1003 master key fit the tubular or barrel-style lock found in many
older hand punch time clocks, irrespective of brand. This included
models from ADP, Acroprint, Amano, Icon, Kronos, HP, and others that
adopted the same access design. :contentReference[oaicite:5]{index=5}
Because the key type was widely adopted by multiple manufacturers,
businesses with legacy equipment often used the same key model across
different clocks. Confirming the lock type on your clock is essential
before seeking replacement parts.
