Liftmaster 02-406-3 Key Set (2) Commercial Door Gate Operators
The LiftMaster 02-406-3 is a replacement key set for select LiftMaster commercial door operator control stations. It is intended for installations where the station lock cylinder is still correct but the keys are missing, damaged, or need to be replaced.
Control station keys are small parts, but they are important for controlled access in commercial door applications. The correct key allows authorized personnel to use the station as designed, while the wrong key can damage the lock cylinder or fail to operate the station.
The 02-406 key family includes more than one version. Some references for 02-406-3 describe it as a two-key set and may reference #301 black replacement keys. Match the key to the lock cylinder and station, not simply to the LiftMaster brand.

Technician Note
Because 02-406-2 and 02-406-3 can appear in similar product searches, confirm the key stamp or station parts diagram. Ordering the wrong key set is a common and avoidable mistake.
Before Ordering Checklist
- Check the existing key stamp if one key is still available.
- Inspect the lock cylinder for wear or damage.
- Confirm the station parts diagram calls for 02-406-3.
- Do not order this as a complete station replacement.
- Verify whether a different 02-406 key version is required for the station age.
Important Ordering Warnings
- Not interchangeable with every 02-406 key set.
- Not a replacement lock cylinder or push button station.
- Some marketplace listings are thin, so verify key code before upload or ordering when possible.
Professional Advisory
Commercial control stations should not be forced or bypassed. If the station is damaged, stuck, or controlling the door incorrectly, have the control circuit inspected by a qualified door technician.

Some listings reference #301 black replacement keys for 02-406-3 applications.
Is 02-406-3 a complete control station?
No. It is a key set. It does not replace the push buttons, enclosure, wiring, or lock cylinder unless the product packaging specifically includes additional parts.
