Ener: Use Light/Wielder Combo to burn open the locks, then hide swiftly.
But but but but...
Ener didn't have LIGHTER + WEL...
Wait a minute :3
MADDOX: Use your awesome physics knowledge to know that when you rapidly heat super-frozen stuff they get extremely fragile and breakable, then tell Ener to use the welder on the lock and then crowbar it.
<ENER>
Maddox!
<MADDOX>
Yo. Need something?
<ENER>
Can I have your WELDER now? :3 I need it to open the DOOR! I will give you my WRENCH just as we agreed on earlier!
<MADDOX>
Hey, my KEEN INTELLECTS is telling me that you can heat up the LOCK and break it with CROWBAR. Ok?
NOW... LET... TRADE!
DA DA DA DUNNNN!!!
Ener acquired... his spiffy and trusty WELDER + LIGHTER COMBO from Maddox!
and
DA DA DA DUNNNN!!!
Maddox acquired... a WRENCH from Ener!
After heating up the LOCKS with his WELDER, Ener activated his engagement mode with his trusty CROWBAR!
And quickly took care of those stupid ODD LOCKS. And he left the DOOR just a crack open, beckoning Ulom to come in to pique his morbid curiosity.
STEP 2 - Open the ROOM DOOR, but leave it only a crack open. CHECK!
And then...
STEP 3 - Hide behind the FREEZER DOOR. CHECK!
Now for STEP 4...
