BEST A3C3 – Frequently Asked Questions

1) What is the BEST A3C3 pin used for?
The A3C3 is a #3 bottom pin for BEST A3 System cylinders. Bottom pins are the ones that sit against the key cuts, so the number designates the pin length that corresponds to a particular cut depth. Locksmiths buy them loose to key, rekey, or repair A3 System cylinders.
2) Will a BEST A3C3 bottom pin work in an A2 or A4 system cylinder?
No. The A3C3 is built for the BEST A3 System specifically. A3 uses its own depth-and-space increment, so pins from another BEST system will not give correct key operation even though they look similar. Order pins that match the system your cylinders are keyed in.
3) Do I need anything besides the A3C3 bottom pin to rekey a BEST A3 core?
A bottom pin alone will not finish a core. Pinning a BEST interchangeable core takes a bottom pin, a master pin where the core is masterkeyed, and a control/top pin stack plus spring for each chamber. The A3C3 covers the #3 bottom pin position only, so order the other depths and components you need for the combination you are cutting.
4) Can a property manager use BEST A3 pins to keep several buildings on one key system?
Yes, that is what the A3 System is for. Loose bottom pins like the A3C3 let a locksmith combinate BEST cylinders on site, so new or repaired cores can be brought onto an existing masterkey system instead of running a separate key for each opening.
5) Is the A3C3 sold as a single pin or in a quantity?
The A3C3 is catalogued as one model with no size or pack option to choose, so there is a single ordering configuration. Locksmiths who pin regularly usually order across the full depth range rather than one pin number.
6) Where can I find BEST's key and core reference information for A3 System pinning?
BEST publishes a Key and Core Brochure covering its key systems and interchangeable core products, and it is available with the A3C3 pin as a downloadable PDF.
