BitLocker Recovery & Decryption Aberdeen

A blue screen asking for forty-eight digits nobody wrote down, with a household or a company stuck on the wrong side of it. Three jobs come out of that. Trace the key that was escrowed somewhere. Open leavers' machines in batches for an employer. Or handle a drive that is dying and locked at the same time. Cracked BitLocker is not a thing that exists, and any supplier hinting otherwise is selling you a story.

Every bitlocker job is diagnosed free. The fixed figure reaches you in writing first, before any tools come out.

No fix, no fee all jobs except electronic and mechanical failures, chip level work, DVR and Forensic jobs. Full pricing is on the data recovery cost page.

// twenty-five faults this bench knows cold

The twenty-five ways they quit

First job on any bitlocker is matching the symptom to the fault. Twenty-odd years in, these twenty-five cover nearly every one that reaches this bench.

48 digits demanded at start-up

Something changed in the hardware or the firmware, the TPM's measurements no longer match, and your data now sits behind one long number. That number can usually be found, which is this page in a sentence.

No record of a key anywhere

Nearly all of these end up at escrow: some Microsoft account nobody remembers signing into, an entry in a directory, an exported file, a printout that has spent five years under a stapler. Intune and Active Directory hold keys people forgot existed. The trawl is methodical, and more often than not it works.

The password gone from memory

GPU-speed attack takes down weak and middling passwords. A genuinely strong password that is genuinely lost earns you a straight verdict, not an invoice ticking over by the hour.

New board, instant lockout

Motherboard swap, TPM clear, BIOS flash, Secure Boot toggle, UEFI update. Every one of those trips the protection precisely as intended by its designers. Your recovery key untrips it.

Windows reinstalled around it

Orphan a data partition through a reinstall and it opens again the moment its key surfaces. Below that reinstall, nothing of consequence was moved or written over.

Failing and encrypted at once

This is the compound case: hardware dying beneath live encryption. We capture it whole, still locked, then decrypt from the stable copy instead of the failing original.

A locked To Go stick

There are three doors into encrypted removable media, and they are the three that open a system drive: your key, your password, or forensic key recovery. In that order of preference.

A crate of machines from leavers

Drives left behind by leavers get decrypted in bulk against the keys your organisation escrowed, with every key matched to its drive on identifier rather than on guesswork.

Moved into a second machine

Separated from its TPM, the volume locks. Designed behaviour, not misfortune. Undoing it takes a few minutes when you hold the key, and considerably longer when you do not.

Header metadata gone bad

Should BitLocker's own structures corrupt on a drive that is otherwise sound, we locate the backup copies and rebuild the headers, and only then attempt decryption.

Tripped by dual booting

Install Linux, or rework the bootloader, and the measurements change and up comes the prompt. Predictable, reversible, and it happens somewhere every week of the year.

Encrypted without anyone being told

Device encryption switches itself on quietly at first sign-in on modern laptops. Owners generally learn about it at a lockout screen, which is poor timing for that discovery.

A key that does not work

An account collects several keys across the years, and the wrong one gets tried first every time. Match on the key identifier shown on screen and guesswork disappears entirely.

The startup stick gone missing

A machine that boots from a key file held on a USB stick locks solid the moment that stick goes missing. Escrow and the TPM remain open regardless, so a lost stick settles nothing.

A PIN forgotten over the winter

Leave a TPM-and-PIN setup unused for a few months and the PIN fades in a way that genuinely surprises people. Your route back in is that recovery key, and one can usually be turned up somewhere.

The company no longer exists

Business dissolved, directory deleted, drives sitting in a box in somebody's garage. We work whichever escrow avenues survive, plus the TPM where the machine still has one.

Bought locked from an auction site

That encryption belongs to the previous owner's account, and only their lawful cooperation opens it. We tell you that before money changes hands, not afterwards.

Decryption stopped at forty-something percent

Interrupt a decryption run with a power failure and half a cipher is left on the disk. Salvage happens from an image, each half handled correctly according to where the boundary fell.

Auto-unlock that forgot how

Set an external drive to unlock itself automatically and it stops obliging once Windows has been reinstalled, because the stored key departed with the old copy. Escrow usually holds a twin.

Self-encrypting drives underneath

A hardware drive doing BitLocker's job in its own silicon fails on its own terms, and the older trust model behind it had documented holes in it. Handled at drive level, and candidly.

The key filed inside the safe

One solitary copy of a recovery key, saved as a text file, parked on the exact volume it unlocks. We appreciate the irony. Escrow appreciates it a good deal less.

Fast encryption's loose ends

In used-space-only mode the files get encrypted and free space is left alone, older deleted copies of those same files included. Carving reads whatever the cipher never covered.

A key rotated while the machine sat offline

Recovery keys rotate automatically across a managed estate, so a laptop that missed checking in around a rotation now sits behind a key the directory replaced weeks ago. Both current and previous keys need retrieving, and it is the older one that works.

A clone that broke the volume

Image an encrypted drive with consumer cloning software and the copy frequently comes out the wrong size, misaligned, or missing its volume header. The encryption is fine. The container is not. Rebuilding from the original is straightforward. Rebuilding from the clone is not.

A TPM that has shut itself for the day

A run of wrong PINs makes a security chip defend itself by closing the door, for a few hours in some cases and until the machine has stood powered down all night in others. Patience really is the fix here. Hammering away at it lengthens the lockout rather than shortening it.

Most lost keys are only mislaid

Start with the cheerful part. A key described as lost has usually just been filed where nobody has looked. Windows almost never encrypts a volume without escrowing the key first, and it goes to a short list of predictable places. The Microsoft account the machine was signed into. An Azure AD tenant at work. An on-premises directory. A text file someone exported and never mentioned again. A printed sheet that got put in a drawer during a rushed handover. Then there is the modern trap. Recent laptops turn device encryption on quietly during first sign-in, and that is how ordinary households get shut out of drives they never knew were protected. So the first action on any lockout is a methodical trawl of every account and directory the machine has ever touched. Tedious. And it resolves more cases here than the expensive tooling does.

Passware, explained without the marketing

Decryption on this bench runs on Passware Kit Forensic, which is the standard product across the forensic trade. Worth stating exactly what it does. It does not break AES. Nothing breaks correctly implemented AES, whatever some website is asserting this week. What Passware does is recover keys. From hibernation files. From memory captures. Straight out of the TPM. Or by aiming GPUs at a human-chosen password, in the cases where a password is the only guard on the door. BitLocker and BitLocker To Go are the everyday volume. VeraCrypt, FileVault, TrueCrypt and LUKS get the same treatment on the same bench. Employers send drives from staff who have moved on and those go through in batches.

Failing and locked, both at once

Order of operations matters enormously when a drive is encrypted and dying at the same time. Unlock attempts are the wrong opening move: each one consumes some of the limited healthy running time left in the drive, and proves precisely nothing. What happens instead is that the disk is imaged cold, still locked, on forensic imaging hardware. Only then, against a stable duplicate, does decryption get attempted with whatever key has been traced. Be clear on one thing before you commit. BitLocker falls in the forensic class of work, so the assessment happens first at no charge, a fixed quote follows on from it, and that figure is settled before work begins rather than afterwards.

// the kit behind the work

Engineering kit, not downloaded software and hope

BitLocker work is key-finding and disciplined imaging. It is never code-breaking, and the equipment reflects precisely that:

Passware Kit Forensic

The key-recovery suite this trade genuinely rates. It lifts keys out of memory captures, out of hibernation files, out of security chips, or reaches one through an accelerated password attack. Keys are what it finds. Nobody breaks the AES underneath, us included.

Memory and hibernation capture

Given a machine that will still start, the live key can occasionally be lifted out of RAM directly, or from the hibernation file. Quickest lawful entry there is, when it is available.

GPU acceleration cluster

Graphics silicon by the rack, grinding out dictionary and brute-force runs at several thousand attempts a second, unattended, round the clock.

Hardware imagers and write-blockers

An encrypted drive that is deteriorating gets captured in full, still locked, and write-blocked throughout. Decryption then happens against the stable duplicate and never against the original.

Key escrow investigation

The methodical trawl: Microsoft accounts, workplace directories, Intune and Active Directory records, exported files, paper in drawers. Most lockouts finish there.

Multi-format decryption

BitLocker first, along with BitLocker To Go, then FileVault, LUKS, VeraCrypt, TrueCrypt, plus several hundred kinds of password-protected file.

Where keys are actually found

Without its key, a sound BitLocker volume stays shut, whatever some confident advertisement tells you. Honest recovery here means finding that key. Escrow trawls. Work against the TPM. GPU-speed attack on the password. And a straight answer wherever that key has genuinely gone for good. Classed as forensic, the work is paid for at the point of quoting rather than on results — while arriving at that quote costs you nothing. Ring 0800 689 0668 and an engineer picks up, not a script.

// before it goes in the box

Before it goes in the box — free the drive if you can

Every scrap of key material should travel with the drive. That means the 48-digit key if it was ever written down, plus whichever Microsoft or workplace account may hold escrow, any exported key files, PINs, plus your best guesses at the password and the variations you might have used. Each item shortens the clock. As for the drive, an anti-static bag suits it, or kitchen foil at a push. Post it tracked and insured, book a courier of your own, or bring it to reception at our Edinburgh location, Edinburgh Data Recovery, 4 Redheughs Rigg, Westpoint, South Gyle, Edinburgh EH12 9DQ, open Monday to Friday, 9am to 5:30pm. No collection service runs from here.

// getting your device to us

Getting it to the bench — plainly done

Nearly everything on this bench came by tracked, insured post. It is the safest way to shift a failing drive, and a parcel handed in at a North-East post office is usually here the next working day.

Still bolted into a laptop, desktop, MacBook, iMac, server or CCTV / DVR box? Get the hard drive or SSD out first. The bare drive travels on its own. Stripping machines down is not a job this lab takes on. Flash soldered to a motherboard, as on Apple Silicon Macs and a couple of very thin laptops, is our one flat no: if it will not unbolt, it cannot be worked on.

  • Bubble wrap, then a rigid box or padded envelope packed tight enough that nothing rattles. Keep the cables, caddies and power bricks at home.
  • Print the shipping & booking-in form (PDF). Name, mobile number, two lines on what went wrong. In the box with the drive.
  • Royal Mail Special Delivery is tracked and insured door to door. Your own courier account does the same job if you would rather use it.
  • Handing it over yourself instead? Reception takes drop-offs at the address below, Mon–Fri 9:00am–5:30pm.

// bitlocker recovery questions

Common questions

Seldom. Most lockouts escrowed a key at some point in their history, whether to a Microsoft sign-in, a company directory or a file somebody saved and forgot. Where no key ever existed at all, a TPM or a memory capture will frequently yield one, and weak passwords fall to GPU attack. The single action that does permanent damage is a reset or a reinstall. Either can destroy key material that was still sitting within reach.
It cannot, and a supplier claiming otherwise should worry you. AES done properly, minus its key, is closed to everybody for good. That is arithmetic, not opinion. Serious practice therefore chases the key. Weak passwords fall quickly. If it is strong and genuinely gone, you get a flat refusal rather than a long invoice with nothing at the end of it.
Very. It happens regularly. Send them as one consignment, and include everything the organisation still has: keys, account names, directory exports. The batch then gets processed together. How complete that supporting material is drives both the timescale and the price far more than the number of drives does.
No. Switch it off. Capture comes first and decryption second, meaning the disk is imaged while still locked and the key gets applied to the image rather than to hardware that is already struggling. Forensic-class rules govern this work: the figure quoted gets settled before anybody starts, though the assessment that produced it costs nothing.
