Step 2: Identify Your Damage
Series 2 / V2
No Damage — New Lock
If your V2 is new or undamaged, you may want to purchase a Minor knob and optional Body Cover to proactively protect the existing lock before squirrels find it. Minor knobs snap fit over the existing knob and come with an optional screw.
Moderate or Complete Knob Damage
For most V2 damage, a Complete Gen3 replacement is the right choice. The examples below show the range of damage we’ve successfully repaired:

| Damage | Recommendation |
|---|---|
| Knob gone, clip visible, shaft intact | Remove clip → Option A |
| Knob gone, shaft damaged or chewed | Option B |
| Shaft severely damaged | Option B — may work, no guarantees. Body cover can hide body damage |
| Cosmetic damage only, cap partially intact | Minor knob, or prep then Option A. Consider waiting until fully damaged |
| Body damage below the knob | Consider adding a Body Cover alongside whichever knob option you choose |

No Damage — New Lock
If your V3 is new or undamaged, a Minor knob and optional Body Cover can proactively protect the existing lock. Minor knobs snap fit over the existing knob.
Moderate or Complete Knob Damage
For most V3 damage, a Complete Gen3 replacement is the right choice. Note that V3 replacement requires a Torx T10 security screwdriver — available as an add-on during Etsy checkout (free for orders over $30, just ask in the personalization field).
