Product Identity

Who It Fits and Who It Does Not

This blank suits locksmiths, property managers or homeowners who need a duplicate for an existing Arrow AR4 lock. It will not operate locks that use a different keyway profile, a different pin count or a different manufacturer's key section.

Questions about this item

Does the key blank come pre-cut or do I need to have it cut separately?

The blank arrives uncut and must be cut by a locksmith or hardware store to match your lock.

Is this blank compatible with other Arrow keyways or only the AR4?

This blank is made specifically for the 6-pin Arrow AR4 keyway and will not fit other Arrow keyways.

What does the 6-pin specification mean when the key is used in my lock?

The blank has space for six pin depths so a locksmith can cut it to operate a standard six-pin Arrow cylinder.
