Can the LM9300 series lock be installed into a Steelcraft LM9000 prepped door?

The discontinued LM9000 series and the current LM9300 series lock chassis are the same. You can replace a defective LM9000 chassis with the LM9300 chassis.   

The LM9300 rod assembly and top strike are not the same as the LM9000 rod assembly and top strike. You cannot replace LM9000 rods and strikes with LM9300 rods and strikes.



The door prep for the lock (chassis & trim) is the same for both the LM9000 and LM9300.

The door prep for the rod assembly, frame prep and top latching between the LM9000 and the LM9300 are very different.
