Keycard Puzzle

During Chapter 13 of Resident Evil 4 Remake, Leon Kennedy is tasked with locating Ashley Graham within the facility on the Island. However, this being a Resident Evil game, finding Ashley requires navigating the facility’s hallways and solving puzzles. You can locate Ashley early in the chapter, but getting to her becomes the real objective.

Ashley is in the room, although Leon will not be able to get inside as the gate is locked. To access the room I had to collect a keycard and upgrade it to the max level to obtain entry. The final upgrade will require me to find the location of the wrench in Resident Evil 4 Remake. The last objective I had was to get to Ashley, but my time inside the facility will be spent looking for and upgrading the keycard.

the first objective I had within the facility was to acquire the keycard. The keycard is hidden in one location, and I had to visit two other locations to upgrade the card to the third level. You will need the location of the wrench here to upgrade the card to level 3.

Location Of The Keycard

I picked up the file inside the facility that updated my objectives. These objectives can be viewed on the map and will let you know the next locations to visit. Therefore, you should next head out to the Dissection Lab, where you will find your keycard. You would have also seen a Regenerator by now; however, you would not need to fight one yet.

Once at the gate of the Dissection Lab, I was required to solve a puzzle at the gate.

Then entered the lab, and here I saw a Regenerator failed experiment lying on the bed. There was a lot of lore and facts about Regenerator to be found there but the card was in the back of the room and by default, it will be level 1.

After that, I received my next task but before I went to the freezer, I was met with the first encounter of a Regenerator so be careful when you open the door.

Upgrading Cards

Next, I head to the Freezer section of the map. The level 1 card granted me access to this section. After entering the freezer and putting my card into the upgrader, I had to wait and fight off the incoming Regenerators for a short time period.

Here I recommend that you run in the opposite direction and parry the attacks, as you will only waste your resources trying to kill the Regenerator. Next, I have to head to the Incubation Lab. This is where I found the machine to upgrade the card to Level 3 and the Biosensor Scope. 

The incubation lab is the main objective here but first I recommend that you avoid the Regenerators contained within the vats and go all the way back and get the biosensor scope. I cannot emphasize how important this scope is to take out the Regenerators.

Location Of The Wrench

Upon finding the machine it does not upgrade the card as it is closed with a grill. It can only be opened by a wrench and the location of the wrench is not easy to find in Resident Evil 4 Remake. The location is only hinted at in the file you see in the backroom. 

And to save you from all the reading I am here to tell you that it is inside one of the regenerators in the vats specifically the one on the left. I recommend using the biosensor scope to confirm it.

So the wrench’s location is inside a Regenerator. I had to shoot the vat and shatter the glass that threw out the Regenerator. Next up, I used the Biosensor Scope to see the Plagas within the Regenerator and kill it. Once killed I found the wrench next to half disintegrated body of the Regenerator. 

Now here is where the fun began as I started to upgrade the card all hell broke loose with the security pushing in as the card was being upgraded so you should keep a heads up as well.

Also, I recommend not to blind-shoot as a stray bullet can lead to you fighting another Regenerator after you hit its VAT.

Finding Ashley

The Final goal of this mission is to get to Ashley and bring her the cure for the virus. So leave the Incubation Lab and head left; use your Level 3 card to exit this place.

You will come to a door you need to unlock, and the holding cell will be right in front of that door. Therefore, use your Level 3 card to get inside the Holding Cell and meet Ashley.

This will trigger a cut scene where Leon gives the vaccine to Ashley, which stops the spread of the virus within her body. This also ends Chapter 13 in the game, and during Chapter 14, you would need to escape the facility.

Final Words

Chapter 13 in Resident Evil 4 is one of the most action-packed chapters of the game. You encounter many enemies and are even introduced to newer enemy types, such as the Regenerators. However, your main objective is to get to Ashley and inject the cure. Although, getting to Ashley is not an easy task. You will have to go around the entire facility, looking for a keycard and getting the necessary updates.

Meanwhile, you have to fight enemies and Regenerators within all this. Then to finally get the level three upgrade of the card, you would need to find the location of a wrench. This wrench may not be as easy to locate until you finally use the Biosensor Scope. You could see the wrench inside one of the Regenerators being kept in the Incubation Lab. 

Here you would need to kill the Regenerator to acquire your wrench and use it to unlock the card upgrading machine. Once upgraded to level 3, you can use the card to get Ashley out and progress on to the next chapter. The puzzle may seem tricky at first. However, once you have found the solution, it will be very satisfying.
