There's a total of twelve special safes to be unlocked in the world of Thief, and laying your hands on the right code can often be a case of fumbling through documents that you'd really rather not read. That's where this section of the guide comes in.
While a lot of the game's special loot can be found tucked away in crawl spaces and hidden rooms, the most valuable items are locked up safely - or so the owner thought - inside these safes. If you're struggling to complete a collection, take a look through our easy reference guide to unlocking every last safe in the game.
Chapter 1: Lockdown safe - Serendi Jeweler's Cellar
You'll find this safe tucked away behind a painting inside the Jeweler's Shop. You'll have to infiltrate this shop as part of the main campaign quest, so you shouldn't have any trouble getting inside. Once you're in, make your way downstairs and into the basement where the Jeweler's tinkering away.
It's up to you whether you want to knock him out or just cause a distraction, but either way you'll have to get your hands on a document called Lygrove's Letter - you'll find it on the workstation he's toiling away at. If you examine this document, you'll find the code you need for the safe: 7-3-9.
Use this combination code on the safe behind the painting, and you'll be able to loot Unique Loot (2/9) - Lyegrove's Jeweled Mask.
Side Job: Beauty Within safe - Miss Scarlett's Town House
You can only gain access to this safe by accepting the special side mission called Basso's Beauty Within - you won't encounter the location while playing the game's main campaign. Leave your hideout to enter Clock Tower Plaza, then find Miss Scarlett's Town House over by the Clock Tower Bookbinders.
When you enter the premises, Miss Scarlett herself will be fast asleep, but keep a close eye out for her father who checks in on her frequently. He's very easy to take down, so knock him out and then get up on to the house's main floor.
The safe you're looking for is over on the southern wall, and you can get the combination to the lock by looking inside the cabinet by the northern wall, on the right-hand side. Use your Focus ability if you're struggling to make it out in the gloom.
If you'd rather just get at the goodies right away, use this code: 8-2-4. The safe contains Miss Scarlett's Hand Mirror, the item you need to complete this side job.
Chapter 2: Dust to Dust - Workshop safe
You'll find this safe inside the Workshop while you're playing through the Dust to Dust mission. The three different parts to the combination are located all around this area. The first is written on the back of the mechanical man, the second is on the metal skull that's on the chair, and the third is simply a case of trial-and-error. Or you can just cheat and use the combination 3-1-4 to get inside and bag Unique Loot (3/9) - Soul of the Automaton for yourself.
The City - Sick Willy's Stash safe
The next safe to have a rummage around is located in Baron's Way South. As it's not a part of the main campaign quest, or any of the many side missions in the game, it can be tricky to find. Once you get to the Baron's Way part of town, head south and then keep your eyes peeled for a ladder that you might be able to lower.
When you find it, fire a Blunt Arrow towards it to bring it crashing down to earth. Climb up it, but don't take the obvious route of the open window when you get to the top. The real target you want to get towards is the closed window just further along to the south - prise it open.
Once you're inside, you'll need to use the in-game date to open the safe. That date can be found on the newspaper nearby, but if you just want the code, it's 8-4-2. There aren't any special collectible items in here, but there is some tasty loot inside - and every penny counts, after all.
Chapter 3: Dirty Secrets - Madam Xiao-Xiao's Private Chamber safe
When you play through the main campaign, you'll eventually find yourself in a secret chamber belonging to Madam Xiao-Xiao. It's located just beyond her office, and you'll encounter it as you play through Thief's main campaign. The code you need to gain access to the safe is actually written on the documents scattered all over the brothel.
If you just want the short answer, go to the safe and use the combination 5-7-3. Just like the previous safe, you won't get your hand on any collectible items here, but you will get a valuable necklace and pocket watch. Well worth the extra effort!
Chapter 4: A Friend in Need - The Keep safe
Once again, this is a safe that you'll come across while working your way through the main story mission of Thief. The combination code you need is actually located in the Architect's Study, an area you explored a little earlier. Once you've found The Great Safe inside the safe chamber, you'll need to first of all reset the lock's mechanism. Do this by pressing the buttons on either side of the safe itself. Just make sure you run quickly over to the other side after pushing one of them.
There are two combinations you need to enter now. On the left-hand side, enter 3-1-9. On the right, use 0-1-8, then open up the safe to continue the story.
Chapter 5: The Forsaken - Room 3E safe
Just like the last safe, you'll encounter this one when you make your way through the story, although you won't necessarily visit this room if you're in a rush. As soon as you get to the asylum's treatment floor, switch on the generator to restore power and start looking around the rooms. Just keep an eye out for the dangerous patients who are wandering around.
Check the plates on the door to find room 3E, then enter it and go towards the safe on the wall. In case you didn't pick up the little note from earlier on in the walkthrough, use the combination code 7-3-1. Inside the safe you'll find a collectible item: Serendi Stone Circles (5/7) - Ivory Circle.
Side Job: Check Mate safe - Mourningside
First of all, you need to accept a job from Basso called Check Mate. You can get to the Mourningside area by going through the door right by the Shady Merchant. Keep an eye out for two people keeping warm by a brazier, then climb your way up the crates, pry open the window you come to, and slip inside Archie Maxwell's House.
You now need to make your way down into the basement of the house, but watch out for the owner Archie who's wandering around his home (the nerve!) - knock him out or sneak away from him, whatever you find easiest.
As well as an unwelcoming occupant, you'll also have to be very careful to avoid the traps that are littered all over the basement. When you find the safe on the wall, use the combination 7-7-6 to get it open. Take the chess piece from inside the safe to finish up Basso's Chech Mate job.
Chapter 6: A Man Apart - East Lounge safe
You'll come across this safe while exploring the Baron's mansion during the main story. You'll be able to get the combination code you need from a guard patrolling the library, but if you'd rather just have the code now, it's 8-8-9. Just be prepared to deal with the two soldiers guarding the first-floor safe - distract them both, or just knock them out to get inside. Once you've opened the safe, you'll be able to loot a special item called Serendi Stone Circles (6/7) - Sapphire Circle.
Chapter 6: A Man Apart - West Hall safe
You'll find this safe in the western hall, just after witnessing the guard being killed by a Graven. You've got no choice but to knock the hall guard out, but once you're inside you can use combination code 0-1-7 to open the safe. There aren't any special collectible items in here, but there is some valuable loot to be had.
Chapter 7: The Hidden City - Loading Docks Interior
This is another section of the game you'll find yourself wandering through while completing the story, but it's pretty easy to miss the safe altogether. As soon as you've finished your long ride down in the lift, you'll see three guards patrolling overhead. One of those guards will eventually disappear down a tunnel, and it's inside that tunnel that you'll find the safe.
Rather than backtracking here after discovering the combination code later on, just enter 6-7-3. Voila! You can now open up the safe and stuff your pockets with the five very valuable bonds inside.
Client Job 4: The Carnal Connoisseur safe - Wine Cellar
First things first, you'll need to visit Vittori and pick up the Carnal Connoisseur client job from him. Once you've got the job in your log, make your way into the Wine Cellar, then look for the safe which is hidden with two triggers behind a painting.
You'll find the combination on two different documents you collect during the mission. Or you can just cheat completely and enter the combination code 8-1-2 to open the safe and gain access to a secret door. Go through that door to get your hands on lots of lovely loot, not to mention the all-important item: Client Loot (7/8) - Octopus.
