BMW & MINI Car Key Replacement & Programming in Windsor & Essex County

🔑 Fast, Mobile BMW & MINI Key Replacement in Windsor

Lost your BMW or MINI key or fob? Don’t tow to the dealership — Canadian Locksmiths offers specialized mobile BMW & MINI key replacement and programming services across Windsor and Essex County.

Since 1989, we’ve helped European car owners with advanced immobilizer and Smart Key systems, providing dealer-level key programming onsite — often for half the dealer cost and without the wait.

💡 We handle CAS, FEM/BDC, BDC2, and BDC3 key systems — safely programming and synchronizing new keys using advanced BMW diagnostic tools.

🧰 BMW & MINI Key Types We Replace or Program

Smart Keys & Proximity Remotes (2014–Present: FEM/BDC, BDC2, BDC3)

Modern BMW and MINI models — including X3, X5, 3-Series, 5-Series, and Cooper — use encrypted Smart Keys controlled by the FEM (Front Electronic Module) or BDC (Body Domain Controller) systems.

Common Smart Key Issues

“Key Not Recognized” or “Key Not Detected” on dash
Push-to-start won’t activate
Remote lock/unlock not working
Lost or stolen Smart Keys

We safely add or delete keys by connecting directly to your vehicle’s BDC or FEM module, programming new keys securely with full functionality (lock/unlock/start/comfort access).

CAS (Car Access System) Keys (2005–2013)

Older BMWs and MINIs use CAS1–CAS4+ systems, which store immobilizer and key authorization data.

Typical Problems

Key turns but car won’t start
“Invalid Key” message
Lost or all keys missing
CAS module data corruption

We perform EEPROM-level repair and key generation directly from the CAS module, restoring start authorization even when all keys are lost.

Transponder & Slot Keys (2000–2012)

Many BMWs used slot-in dashboard keys with integrated transponders.
We can cut and program replacement slot keys and synchronize them to the immobilizer and ECU.

⚙️ Advanced BMW & MINI Systems We Work On

FEM/BDC / BDC2 / BDC3 Explained

BMW’s Body Domain Controller (BDC) family manages Smart Key pairing, immobilizer data, and comfort access functions.

BDC1 (F-Series, early G-Series) – Standard keyless and immobilizer data storage
BDC2 (2020–2023 models) – Encrypted EEPROM, stores key certificates for enhanced theft protection
BDC3 (2023–Present) – Latest secure gateway architecture used in i-Series and high-end G-Chassis vehicles

At Canadian Locksmiths, we can:

Read and back up your existing FEM/BDC EEPROM data
Generate and code new Smart Keys without replacing modules
Synchronize immobilizer, ECU, and key data
Repair or restore corrupted BDC firmware caused by jump starts or module failures

💡 This service avoids dealership-only key generation and saves thousands in module replacement costs.

EEPROM & Module-Level Programming

If all keys are lost, we extract and modify data from your CAS, FEM, or BDC module using secure, non-invasive EEPROM read/write methods.
This allows us to:

Create new working keys
Restore synchronization between immobilizer, ECU, and transmission
Reactivate push-start and remote features

⚠️ Common BMW & MINI Key & Lock Problems We Solve

“Key Not Recognized” / “Key Not Detected” messages
Car won’t start even after key insertion
Lost or stolen Smart Keys
FEM / BDC module corruption after power loss
All keys lost — immobilizer locked
Remote buttons not working or unresponsive

We use OEM-level BMW software to restore communication between the key, immobilizer, and control units.
