Overhead Door 1000 - 1300 [R1003M BLANK]

The Overhead Door 1000–1300 replacement key series is designed for Overhead Door and Windsor garage door locks using key codes 1000 through 1300. Commonly used on garage door T-handle locks, overhead door locking systems, and Windsor garage door hardware, these replacement keys are cut to code for a dependable fit and smooth operation.

Important: Lock codes 1000–1300 were manufactured using two different keyways over the years. The correct replacement key depends on the keyway used on your lock. This page is for locks using the R1003M key blank. If your lock uses the alternate keyway, you may need the Overhead Door 1000–1300 [HL1 Blank] replacement key series instead. Customers should compare their existing key or keyway before ordering to ensure the correct replacement is selected. If you are unsure which keyway your lock uses, please upload a photo of your key or lock face with your order, and we will help identify the correct replacement key.
