Product Description

The DORMAKABA 203037-000-01 is a right-hand service kit for the Simplex L1000 Series mechanical pushbutton lockset. This kit supplies the internal components needed to restore or rebuild a worn or damaged L1000 right-hand lock assembly. It covers the core mechanical elements of the lock: the chamber shaft bushing, clutch assembly, combination chamber, drive shaft configurations for both key-override and non-key-override setups, lever return spring, fixed sleeve, and stop plate. Locksmiths and door hardware technicians install this kit during scheduled maintenance or corrective service on L1000 units.

This service kit is intended for right-hand door applications using the Simplex L1000 Series pushbutton lock. It addresses common wear points in the mechanical combination mechanism and lever return system. The included drive shaft options accommodate both standard no-key-override and key-override configurations, making the kit suitable for a range of L1000 field installations without requiring separate part orders.

Installation Notes

Installation should be performed by a qualified locksmith or door hardware technician familiar with Simplex L1000 Series disassembly and reassembly procedures. Disengage the door from service and ensure no load is on the lever mechanism before disassembling the lock body. Follow the manufacturer service documentation for correct component sequencing, particularly when selecting the appropriate drive shaft for the existing key-override configuration. Verify proper lever return and combination function before returning the door to service.
