Find the lift key beside Fellows on the Cavern B spire
The Terrible Lizards crew lift key location is at the top of the spire in Cavern B, beside Dr. Jonathan Fellows and his last-words note. To reach it, first collect dynamite in Cavern A and blast open Cavern B's blocked entrance. Bring the key back to the outpost lift and DJ to continue the Chapter 4 escape.
This route comes from FusionZGamer's full-release player experience, which includes the pickup and the return to the lift. It contains Chapter 4 story spoilers. The official Terrible Lizards Steam page provides the full-game listing.
Reach the outpost clue and collect Cavern A's dynamite
Progress through Chapter 4 until you reach the outpost after rescuing DJ and escaping Dennis. Investigate the lift control, which requires a key, then finish the outpost's special-spectrum lighting objective and check on DJ.
Fellows's recording explains why the key is missing. It is the lift system's fail-safe, and he took it away to prevent the creatures from reaching the surface. He identifies Cavern B as his destination.
Before following that lead, enter Cavern A. Follow its climbing and goo-bounce route to the dynamite. The player's objective explicitly calls for finding dynamite there, then changes to using it to access Cavern B.
Once you have it, return to the blocked Cavern B entrance. Place the explosive at the obstruction and activate the detonator. The opened passage gives you access to the key route.
| Landmark | Action |
|---|---|
| Outpost lift | Inspect the lock and follow the story objective |
| Outpost lights and Fellows recording | Learn that the key went to Cavern B |
| Cavern A | Collect dynamite |
| Cavern B entrance | Place and detonate the explosive |
| Cavern B spire | Climb to Fellows and collect the key |
Climb the spire and collect the key before leaving
Continue through Cavern B until the objective directs you to search the spire for the key. This is a vertical climb through the cavern's traversal route. Use the available ledges, poles, and goo-assisted movement to keep working toward the top.
The identifying landmark at the destination is Fellows's body. Jordan recognizes him, and the player then identifies and grabs the key to the lift. Fellows's last-words note is at the same destination.
Collect the key itself before taking the onward route. Reaching Fellows or reading his note is not the same action as picking up the item needed by the lift.
The recording establishes the cavern, spire, and final pickup landmark. It does not supply a reliable compass direction for every jump, so use those named objectives and the climb's visible supports to orient yourself rather than expecting a numbered sequence of identical platforms.
Return to DJ and use the key at the lift control
After collecting the key, follow the escape route out of the spire area. Dennis appears during the return, and the path continues through another traversal and pursuit sequence.
Continue until the objective is to return the key to the lift. Reunite with DJ at the outpost, then interact with the lift's key control. In the full-release player experience, inserting the key allows the lift to start its ascent.
The key resolves the locked lift system, but there is more of the finale ahead. Dennis interrupts the ride, and Jordan must follow the catch up to the elevator objective through an alternate climbing route. Finish that sequence and the final kick interaction, then continue with DJ to the surface.
FAQ
Which cavern contains the lift key?
Cavern B. Climb its spire to the top and find the key beside Fellows and his last-words note.
Why do I have to visit Cavern A first?
Cavern A contains the dynamite needed to open the blocked Cavern B entrance. Collect it, return to the obstruction, and use the detonator to access the key route.
What does Fellows's recording explain?
The key is a fail-safe without which the lift system cannot operate. Fellows took it to Cavern B to keep the creatures cut off from the surface.
What should I do after picking up the key?
Follow the return route through the Dennis encounter, reunite with DJ, and use the key at the outpost lift control. The subsequent elevator interruption is part of the final escape sequence.
