4 Best EfT Keys on the Interchange Map [Ranked]

Object #11SR Key Card

Our top key on this list will be Object #11SR, mainly for its high-value loot potential – weapon mod spawns, three weapon boxes, modded M4A1, and frequent rare loot. That's a lot, huh? Plus, this particular key sits at around 200,000 roubles, but with 15 uses, it offers strong ROI after just one successful run... damn, this just has to be the best key on Interchange.

Whether you are a frequent or occasional Interchange player, this key card is truly powerful, and you should really have it. All in all, Object #11 SR is a multifunctional key, offering not just loot but also strategic advantages in both raid longevity and extraction; for more information on that, check out our article on the best exits for Interchange.

Not to mention, this key has a chance to spawn on basically every Scav boss in the game, on the cultist priest, and under the "giving tree" behind Old Gas on Customs. One last thing before we move on to the next key is that while you are in the process of activating the saferoom, someone can take it from you. All in all, playing without this key on Interchange might make you uninstall Escape from Tarkov, so be sure to get this one, end of story.

KIBA Arms Keys

Kiba Arms inner grate door key and Kiba Arms outer door key open the inner and the outer part of the door respectfully, so they will be treated as one position on this list as our top 2 pick. While they might make you think that Escape from Tarkov is pay-to-win, just wait until we talk about their utility.

These keys together go for about 200k roubles on the flea market right now, but the Kiba store has some amazing attachments and weapon spawns — two weapon boxes, ammunition spawn, rare armor spawns on the mannequins, grenade spawns, two cash registers, cash spawns, and a possible DVL-10 spawn on the weapon rack. Some weapon combinations and attachment spawns make them really good money-makers, especially with rare attachments or attachments needed for a quest. Yeah, they are expensive, but because they are so useful, you might want to check out the best sites to buy EfT roubles for a good price.

Object #21WS Keycard

This is another keycard on the list and it's our third pick for the best Interchange keys. Right now it sells for about 50k roubles on the flea market, and inside there are three weapon boxes, an MPX spawn, a Trooper armor spawn, weapon mod spawns, and rare loose loot.

For this keycard to be activated you need the power to be on. The best way to use this keycard is if you are doing stash runs outside the mall and loot the object when you come close to it. This key is pretty inexpensive and you get excellent potential loot, not to mention it is outside the mall so PVP is not as frequent, although you may run into people doing the same strategy as you. For Interchange this is one of the high priority keys.

Necruspharm Pharmacy Key

Lastly, we have Necruspharm Pharmacy Key. Similar to the previous position, this key is a good way to get medical items there are loose medical loot spawns, a LEDX, an Ophthalmoscope, a Saline solution, and hydrogen peroxide spawns. The last two items are pretty common, but if for some reason you need those specific items you can find them here.

This key costs around 50k on the flea market. Not much to say about this key, it does not cost much, and if you mostly play Interchange and you need meds you can stock up on medical supplies with a help of two other keys on this list.
