Key Highlights:
- The Freezer Electronic Lock Terminal is an optional puzzle in Chapter 13.
- Solving it unlocks the room containing the LE 5 submachine gun.
- The solution changes on Hardcore and Professional difficulty.
The Freezer power puzzle in Resident Evil 4 Remake unlocks the room containing the LE 5 submachine gun, one of the game’s most useful late-game weapons. The puzzle uses an Electronic Lock Terminal, requiring Leon to route electricity to every Power Node before confirming the circuit.
Unlike the Dissection Room terminal, the Freezer puzzle is optional. You do not need to solve it to complete Chapter 13, but doing so rewards you with a free weapon that performs exceptionally well against Regeneradors, especially when paired with the Biosensor Scope later in the game.

Where to Find the Freezer Power Puzzle
The Freezer Electronic Lock Terminal is located inside the Freezer during Chapter 13 on the Island.
Leon cannot access the area immediately. First, he must solve the Dissection Room Electronic Lock Terminal to obtain the Level 1 Keycard. After leaving the Dissection Room, return to the Power Control Lever and reroute electricity from the Dissection Room to the Freezer.
Once the power has been redirected, use the Level 1 Keycard to enter the Freezer. The Electronic Lock Terminal is mounted beside the locked weapon room containing the LE 5.
How Does the Freezer Electronic Lock Terminal Work?
The Freezer terminal works in the same way as the other Electronic Lock Terminals found on the Island.
Each control rotates part of the electrical circuit. Your objective is to connect the power source to every required Power Node before selecting the central POWER symbol to confirm the calibration.
The puzzle has two different solutions:
- Assisted and Standard
- Hardcore and Professional
The following solutions assume the puzzle is still in its default starting position. If you have already rotated the circuit, return it to its original layout before following the button sequences below.
Assisted and Standard Freezer Puzzle Solution
The Assisted and Standard version of the Freezer puzzle requires electricity to reach five Power Nodes.
Starting from the terminal’s default layout:
- Press the first circuit control twice.
- Press the second circuit control twice.
- Press the third circuit control three times.
- Press the fourth circuit control three times.
- Move the selector to the central POWER symbol.
- Confirm the calibration.
The shortened solution is:
2-2-3-3
All five lightning-bolt symbols should illuminate before Leon confirms the circuit. The locked weapon room opens once the terminal accepts the calibration.
Hardcore and Professional Freezer Puzzle Solution
The Hardcore and Professional version uses a different circuit arrangement.
Starting from the untouched terminal:
- Press the first circuit control three times.
- Press the second circuit control once.
- Press the third circuit control three times.
- Press the fourth circuit control three times.
- Select the central POWER symbol.
- Confirm the calibration.
The shortened solution is:
3-1-3-3
The circuit only unlocks the room after every required Power Node is connected and the POWER control has been confirmed.
Why Is the Freezer Puzzle Not Working?
The numbered solutions only work when the Electronic Lock Terminal is in its original configuration.
If you rotated any circuit sections before following the sequence, your current layout will no longer match the default starting position. Reload a recent save or manually rotate the circuit until it matches the original arrangement.
The door will also remain locked until Leon selects the central POWER symbol and confirms the calibration. Illuminating all five Power Nodes does not complete the puzzle by itself.
Check the selected difficulty as well. Assisted and Standard use the 2-2-3-3 solution, while Hardcore and Professional require 3-1-3-3.
What Does the Freezer Puzzle Unlock?
The Freezer Electronic Lock Terminal unlocks a small side room containing the LE 5 submachine gun.
The LE 5 is free to collect and does not replace the Level 2 Keycard objective. Leon must still place the Level 1 Keycard inside the Freezer’s card-writing machine and survive until the upgrade process finishes.
This distinction matters because the keycard upgrade is required for progression, while the Electronic Lock Terminal and LE 5 are optional.
Is the RE4 Remake LE 5 Worth Getting?
The LE 5 is worth collecting during most standard playthroughs because the Freezer puzzle costs no ammunition and rewards Leon with a free weapon.
The submachine gun offers:
- High ammunition capacity
- Low recoil
- Compatibility with the Biosensor Scope
- Strong crowd-control potential
- An Exclusive Upgrade that increases its penetration power by five times
The LE 5 can help expose and damage the internal parasites inside Regeneradors when fitted with the Biosensor Scope. However, a rifle such as the Stingray generally delivers more damage per precise weak-point hit.
I would treat the LE 5 as a flexible late-game submachine gun rather than the single best Regenerador weapon. Its rapid fire and scope compatibility are useful, but its lower per-shot damage can consume more ammunition than a rifle. Community testing also supports rifles as the more efficient choice when targeting individual parasites.
The LE 5 is especially attractive when Leon has not invested heavily in the TMP. Players with a fully upgraded TMP may prefer to sell one weapon rather than spend Pesetas upgrading two submachine guns.
Can You Return to the Freezer Later?
Leon can return to the Freezer and collect the LE 5 after upgrading the keycard, provided he has not progressed beyond the Island laboratory’s accessible route.
Return to the Power Control Lever and redirect electricity back towards the Freezer. The Electronic Lock Terminal becomes usable again once the area receives power.
This means you do not have to solve the optional puzzle during the Regenerador encounter or while waiting for the Level 2 Keycard. You can complete the required objective first and return once the immediate danger has passed.
I would still collect the LE 5 before leaving the laboratory section. Resident Evil 4 Remake eventually prevents Leon from returning to earlier Island areas, so the weapon is missable within the playthrough.
What Happens After the Keycard Upgrade Starts?
Placing the Level 1 Keycard inside the card-writing machine begins the upgrade to Level 2 clearance.
A Regenerador enters the Freezer while the machine processes the card. Leon does not need to kill the creature to complete the upgrade.
Keep moving around the Freezer and avoid becoming trapped between the Regenerador and the storage units. The cold environment initially slows the enemy, but it becomes more aggressive as the encounter develops.
Once the machine finishes, collect the Level 2 Keycard and leave the Freezer. The upgraded card allows Leon to continue towards the Level 3 Keycard objective.
Players who want a later test against a stronger member of this enemy family can complete The Wandering Dead Merchant Request, which centres on defeating a powerful Regenerador variant.
