How to Get a Decoder in ROB RUN

What a decoder does

If you own a base, plan around decoders. They are how other players get through a locked door in ROB RUN, the free crime sandbox Kefir (Kefir Games) runs in Steam Early Access, where raids on rival hideouts are a core crime. For the wider picture, start at our ROB RUN game hub.

Two players describe the same job: a raider works on your door’s fuse box, and one breach burns through several decoders. They are spent on the way in, so every door costs the attacker a stack.

Each decoder shows a Breaching value. One player guide shows one at Breaching 1 and says purple ones breach harder, with no number given.

Since the November 4 patch, more decoders fit in one inventory slot, and gold bars got the same change. Kefir did not publish the new limit.

Where to get decoders

As of November 9, 2026, nobody has published a full decoder recipe. Only one of four known routes has more than a single player behind it.

Route	Backed by	What is known
Lenny’s Motel barter door	Two sources	Item cost not published
Season pass	One source	After 3,000 crowns spent
Electronic stores	One source	No drop rate given
Purple action camera trade	One source	Gives a level 3 decoder

The barter door at Lenny’s Motel

Two players point to a suspicious door on the right inside Lenny’s Motel. It is a trading post, not a shop: specific items go in, heist tools such as drills, glass cutters and decoders come out. The decoder price there is unknown, so read the door’s list before you sell loot you may need. Our beginner’s ROB RUN guide covers the motel.

Routes from a single player

• Season pass. One player reports that Season 1 rewards sit under Esc, Customization, Seasons, View and cost crowns. Decoders open up after 3,000 crowns spent. That player got crowns after turning in and serving a sentence.
• Electronic stores. The same player names looting these stores as a source, with no drop rate.
• Action camera. A camera fills a little with each criminal action. By that player’s account, a filled purple camera trades at the Lenny’s barterer for a level 3 decoder. Purple cameras drop from looting or cost 90,000 in the shop.

How many decoders a breach takes

Kefir has not published a count. The only one comes from a single player using Breaching 1 decoders: a fresh trailer door starts at security level 5, and that player’s trailer beside a bunker read level 8, because the bunker adds 3. That door, the player said, would take eight decoders.

Keep the 8 in context. It is a bonus from where the trailer stands, not defense anyone built. Decoder quality also moves the count, and the purple figure is missing.

Setup	Protection shown	Source
New trailer door	5	One player
Trailer beside a bunker	8	One player
Upgraded House	15	One player
House with 10 purple fuses	45	One player

The House rows come from a different player, who upgraded a Tier 2 trailer and reports 27 fuse slots.

Protecting your base

Work through these from free to costly.

Shut the door and the gate

This costs nothing and matters most. Players report that an open door needs no breach at all: anyone can walk in and empty the place.

Pick the plot

Two separate players recommend a spot next to a bunker or a checkpoint. The +3 bonus is one player’s number, but the advice has two backers.

Fill the fuse box

Players report that every fuse you add raises protection and forces a raider to spend more decoders. One player found purple fuses among the season pass rewards on the page that opens after 1,250 crowns are spent.

Add a fence

Two players say a fence puts a gate with its own control panel in front of the house, so raiders must breach that before they reach your door. One player prices the Mesh Fence at 25,000 to unlock and 15,000 to buy in the black market. See it as an extra layer, not a wall nobody can cross.

Fit a security system

According to one player, a security system on the fuse box sends a breach alert to you and your whole clan in chat. Put one on the gate and one on the house so there is time to respond.

Keeping valuables safe

A breach gets a raider past the door, not into everything inside. The small safe is the main backstop. A single player found that a locked small safe opens only with a master key, a Tier 2 item, even after decoders have done their work. Reaching Tier 2 costs over a million by that player’s account, so early in a wipe, few raiders are likely to carry one. The safe sits in Construction under furniture. Unlock the Small Nightstand first, then pay 50,000 to unlock the safe and 32,000 to buy it. That player’s house plan had room for two.

What goes inside, per the same player: loot worth keeping, keys, your own decoders and most of your cash. Leave only small sums on the laundering desk. Two players agree that cash on a table or the desk can be taken once raiders are in, while money already in the bank stays put.

The bank is the one point with an official answer. The support center says banked money is safe from theft until the next wipe, and Kefir wipes plots, bases, weapons and cash every seven days as of November 9, 2026. Our ROB RUN wipe page has the reset rules, and the ROB RUN money guide walks through opening an account and laundering cash.

Logging out at Lenny’s Motel

Where you quit matters. Two players give the same routine: move what you want to keep into your inventory, then log out at Lenny’s Motel, where nobody can kill you. A raider who breaks in later finds little worth the decoders.

One of those players adds that your character stays in the world for about 3 minutes after you leave. Spend those minutes at the motel, not at your base.
