Red case with matte finish.
Hidden 5G curtain wheel.
Hard-plate straight above the keyway.
If you can see the bolt in the door gap you will see the chamfered edges at the top and bottom of the bolt.
Drill to pick:
Measure 21mm up from the top of the keyway then 12mm towards bolt.
Use a 6mm hard-plate drill bit followed by a flat ended drill bit to completely open up the hole without damaging the levers.
Drill for the stump (the last resort):
Measure 21mm up from the top of the keyway then 16mm towards bolt. Consecutive holes may need to be drilled to remove the stump. Use a 6mm hard-plate drill bit.
