X3052 replacement tubular key cut by code on a 1137S tubular blank for many Fort Tubular locks that use this numeric code range (X1001–X8704). Computer-cut by The Lock Doctor LLC for accuracy and smooth operation—no copy-of-a-copy wear. Ideal for vending machines, T-handles, and utility locks keyed to this exact code. Works only if your lock is actually keyed to X3052 and uses a 1137S blank; rekeyed locks or different keyways will not operate. Verify the stamped code and tubular blank before ordering.
