This key is for OSH KOSH trunks that have a lock that either says CORBIN LOCK CO or CORBIN. If your trunk says CORBIN P&F- this key will not work. Please contact us if that is the case and we can give you more details. This key will be cut to code and the 5 pin Ilco 1000 key blank will be manually shortened to accommodate this 4 cut key code. The original 4 pin key blank used for these is no longer available due to the age of 75 years or more.
