ON CLIMB OUT WHEN SELECTING THE LANDING GEAR UP, THE LANDING GEAR RETRACTED NORMALLY, BUT WHEN FULLY UP THE RED UNLOCKED ANNUNCIATOR REMAINED ON. THE CREW CYCLED THE GEAR SEVERAL TIMES, BUT COULD NOT GET THE LIGHT TO EXTINGUISH. THE CREW ELECTED TO DIVERT TO HOME BASE KAPF (NAPLES FL) FOR MAINTENANCE ATTENTION, WHERE AN UNEVENTFUL LANDING WAS ACCOMPLISHED. UPON TESTING AND INSPECTION OF THE LANDING GEAR BY THE MRO, IT WAS DISCOVERED THAT THE DIMENSION FOR THE EXTENDED NLG STRUT WAS OUT OF TOLERANCE (TOO LARGE) AND WAS NOT ALLOWING THE NLG UPLOCK HOOK TO LATCH CORRECTLY.
