Dormakaba 012-509971-KEP – Frequently Asked Questions

1) What does the Dormakaba 012-509971-KEP spring actually do in the lock?
It is the outside lever spring, the part that returns the outside lever to horizontal after it is released. When a lever starts to droop or stops springing back cleanly, this is normally the component being replaced. It is a genuine Dormakaba OEM replacement part for their mechanical lock assemblies.
2) Can a Corbin Russwin swivel spindle pin and set screw be used in place of the Dormakaba 012-509971-KEP lever spring?
No - they are different parts doing different jobs. The Dormakaba 012-509971-KEP is an outside lever spring, the coil that restores lever return action in a Dormakaba commercial mechanical lock, and it ships as a 10-pack of genuine OEM parts. The Corbin Russwin 499F838 is a swivel spindle pin with a set screw, a spindle retention component listed for 1-3/4 inch door thickness. If the lever on a Dormakaba lock droops or fails to return to horizontal, the spring is the part to order; a spindle pin will not restore lever return.
3) How many springs come in the Dormakaba 012-509971-KEP part number?
Ten. The 012-509971-KEP is sold as a 10-pack, which is how Dormakaba packages it for shops and in-house maintenance teams servicing lever return problems across multiple doors. If you only need one lever repaired, you are still buying the pack of ten.
4) Is the 012-509971-KEP lever spring a commercial part or for residential locks?
Commercial. Dormakaba lists it under its commercial mechanical lock parts, so the springs are sized for the commercial-grade lever assemblies used in offices, schools, healthcare, retail, and multi-tenant buildings, not residential knob sets.
5) Do I need anything else besides the spring to fix a sagging outside lever?
Not necessarily. The 012-509971-KEP covers the spring itself. If the lever is loose on the spindle rather than failing to return, the fault is usually in the spindle or retaining hardware instead, and a spring will not correct it. Diagnose which one it is before you tear the lock down, since these are separate parts in the Dormakaba rings, spindles and springs group.
6) Is the 012-509971-KEP specific to the outside lever, or can I use it on the inside lever too?
Dormakaba identifies 012-509971-KEP specifically as the outside lever spring. Inside and outside lever springs are not always the same part in a commercial lever lock, so order by the position you are servicing rather than assuming one spring covers both sides.
