How to Increase Security Skill in Oblivion Remastered
Few skills in The Elder Scrolls IV: Oblivion Remastered are more relevant to thieves, assassins, and treasure hunters of opportunity than the Security skill. Whether sneaking through the Imperial City alleys or prowling into Ayleid ruins to loot treasure, mastery of this skill dictates how well you can open doors and chests, discover treasure, and slip away unnoticed. When magic-wielding characters can cast the Open Lock spell, the rest of us are forced to fall back on Security ability in Oblivion, and on our selection of lockpicks, to slip through locked doors and chests. In Oblivion Remastered, the lockpicking mini-game feels more responsive and smooth, but success still depends a lot on your skill level and timing. The higher your Security level, the fewer broken lockpicks, the faster unlocking, and the greater chance of scoring rare treasure without frustration. This tutorial breaks down exactly what the Oblivion Security skill does, how to level up fast, and where to find the best trainers and skill books to get Master level in no time.
What the Security Skill Does in Oblivion Remastered

Make Your Own game Server
The Lockpicking skill regulates a character's lockpicking of doors, chests, and other containers in Cyrodiil. The greater the skill level, the less strict the lockpicking is; tumblers fall less frequently when mistakes are made, giving you more chances to succeed before your lockpicks break. In the remastered Oblivion, lockpicking is slightly less choppy than in the original 2006 game, thanks to enhanced frame pacing and responsiveness, but the fundamental mechanics are the same. You must listen for the "click" sound and the bounce pattern of the tumbler to know when to set it in place. Here's how gameplay is changed by each Security skill level in Oblivion Remastered: Novice (0–24): 4 tumblers will drop when you fumble. Lots of lockpick misfires and a tough learning curve. Apprentice (25–49): 3 tumblers will drop when you fumble, with some room to spare. Journeyman (50–74): Just 2 tumblers reset when you fumble, so most Average locks are easy pickings. Expert (75–99): Only 1 tumbler falls when you fumble, and challenging locks become quite simple. Master (100): You never drop tumblers when you fail, so even the toughest locks are no trouble to open. You'll barely ever break a lockpick before your character reaches Security Master and can open almost any box in a second, so every manor and dungeon in Cyrodiil is your own treasure trove.
How to Level the Security Skill in Oblivion Remastered
The best method of getting the Oblivion Remastered Security skill up is by lockpicking. Whenever you successfully place a tumbler into position, not just when you actually open the lock, you get experience towards the skill. This means you can fail or abandon a lockpicking attempt and still progress, and it is a faster and more effective way to level than opening every chest you find. These are the three main ways to boost your Security skills: Set Tumblers While Lockpicking - Each set of tumblers you successfully set earns you XP, even if you abandon before unlocking the lock. Learn from Trainers - Invest gold in master trainers located in the vicinity of Cyrodiil for guaranteed boosts in skill. Read Security Skill Books - Locate valuable books that bump up your Security skill one full level permanently.
Fastest Way to Max Out Security (Using the Lockpicking Glitch)

For those who don't mind exploiting an in-game bug, Oblivion Remastered still retains the legendary Security maxing bug that will take you there within a few minutes. How to perform the trick: Approach a locked container or door (difficulty does not affect the trick). Begin the lockpicking minigame. Set one tumbler in position and continue mashing the "Set" button without a concern for timing; inputs will still register as attempts to set. Xbox: Press A PlayStation: Press X PC: Press Spacebar Keep spamming for a few minutes. You’ll hear the distinct sound cue for skill progression several times. Exit the minigame, and your Security level will have jumped dramatically, in many cases, straight to 100. Even though this glitch bypasses normal gameplay, it’s an effective way for stealth-based players to skip tedious leveling and focus on thieving or dungeon crawling.
All Security Skill Books in Oblivion Remastered
There are five Security skill books scattered throughout Cyrodiil, each of which provides a permanent +1 bonus to your Security skill upon reading. Some are faction or quest-specific, while others are in convenient locations. Lock Picking Improvements - Purchased (or stolen) from Mach-Na's Books in Cheydinhal; also on an altar within Fingerbowl Cave. The Locked Room - Located under Anvil Castle in the Smuggler’s Cave, inside a chest. Proper Lock Design - Appears in Dareloth’s house (Waterfront District, Imperial City) after becoming Guildmaster of the Thieves Guild. Surfeit of Thieves - Found as random loot throughout Cyrodiil. The Wolf Queen, v1 - Located in Dro’shanji’s house in Bravil. Reading all five is an excellent method of substituting for normal training and reaching higher levels of Security early, especially on stealth-based builds.
All Oblivion Remastered Security Trainers
If you do not prefer to train to mastery without employing exploits, several Security trainers in Oblivion Remastered can be found on the planet. Depending on your current level, you will have to find the correct trainer level to move on. Malintus Ancrus - Located in the southwest of Chorrol. Trains Security from 0 to 40. Samuel Bantien - In Imperial City, Talos Plaza District. Trains Security from 0 to 40. Dro'shanji - Resides in Bravil, north-central region. Trains up to level 70.

Buying lessons can become costly, but it's generally the quickest and most secure method of achieving Expert or Master rank without burning through lockpicks. Security Leveling Tips for Efficiency Save before locking picking. Even with high proficiency, lockpicks will still break on difficult Master locks. Carry multiple lockpicks. They're light and irreplaceable, always buy spares from fences to the Thieves Guild or Shady Sam near the walls of Imperial City. Avoid brute-forcing locks early on. Low-skilled characters should use patience and rhythm rather than random inputs. Use auto-attempt strategically. The "Auto Attempt" function is tempting, but never worth it except when your skill level is very high. Become a member of the Thieves Guild at the earliest opportunity. Access to fences and lockpick vendors simplifies the early game for stealth characters.
Why the Security Skill Remains Relevant in Oblivion Remastered

Although later Bethesda RPGs like Skyrim and Starfield simplify lockpicking, Oblivion Remastered maintains the suspense of time-sensitive tumbler locks. The Security skill in Oblivion is actually a test of patience and accuracy, which rewards good play and investment. Even for magic- or combat-oriented players, it is worth putting points into Security, especially in Ayleid ruins, Oblivion Gates, and Thieves Guild quests, where chests with locks typically hold unusual enchanted gear, Varla Stones, or high-capacity soul gems. An increased Oblivion Remastered Security skill makes every dungeon crawl a more pleasant experience. With a full loot bag and functional lockpicks, players can focus on seeing what's around the next corner and getting creative, not on getting frustrated and being toolless.
Final Thoughts
Mastering the Security skill in Oblivion Remastered is one of the most satisfying experiences in the game. Whether you’re a dedicated thief, a curious adventurer, or a meticulous collector who refuses to leave any chest unopened, improving this skill opens countless opportunities. By combining efficient tumbler-setting, a few key books, and expert trainers like J’baana, anyone can reach Master rank and unlock the full potential of stealth gameplay in The Elder Scrolls IV: Oblivion Remastered. With practice, patience, or a little bit of lockpicking trickery, you’ll soon turn every sealed chest in Cyrodiil into an invitation rather than an obstacle.
