Immobiliser & ECU Synchronisation

Modern vehicles rely on synchronised control units (ECU, immobiliser, key, gearbox) to allow the engine to start. If one of these components has been replaced, corrupted, or reset your vehicle may no longer start, even if everything is mechanically fine.

🧠 Immobiliser System Diagnostics & Programming

At OBDTech, we specialise in advanced immobiliser repairs and synchronisation. This includes:

• ECU ↔ Immobiliser synchronisation
• TCU ↔ Immobiliser matching / linking (gearbox & transmission control units)
• Used or NEW ECU / BCM / BSI / CAS / FEM module adaptation
• Resetting immobiliser systems when all keys are lost
• Bypass & off solutions (case-by-case, not generic)

⚠️ Why Not Use Cheap Bypass Tools?

We always recommend dealer-level methods where possible. Many aftermarket "IMMO OFF" solutions cause more issues than they solve disabling security functions, triggering dashboard warnings, or interfering with keyless entry, ABS or cluster modules.

At OBDTech, we work with factory-level tools and data ensuring proper synchronisation across all modules in your car. Our approach is safe, proven, and keeps your vehicle stable and secure.

Whether you've swapped ECUs, bought a second-hand transmission, or lost all keys and need full synchronisation from scratch we’ve got the tools and knowledge to bring it all back together properly.

🛠️ ESL / ELV / EIS Steering Lock Repair & Bypass

One of the most common immobiliser-related failures in modern vehicles involves the steering lock system also known as ESL (Electronic Steering Lock), ELV (Electronic Steering Column Lock), or EIS (Electronic Ignition Switch).

Common issues include:

• Internal motor failure
• Worn or broken plastic gears
• No START or NO response when inserting key or pressing start
• Steering remains locked even though key is authorised

We offer professional repair, reset, or bypass solutions for faulty steering lock modules across a wide range of vehicles including:

Audi, BMW, Land Rover, Mini, Mercedes-Benz, Porsche, Smart, Jeep, Chrysler, Dodge, Volkswagen, Bentley

Our solutions are case-by-case not generic dumps or unsafe emulators and are designed to restore full function without compromising vehicle security. In many cases, we can repair or safely bypass a failed steering lock module, getting your car back on the road quickly and correctly.

Best to call us directly to discuss your issue and vehicle model, as solutions vary depending on hardware type and fault condition.

💀 The Locksmith Kill Scenario

We’ve seen it too many times... A mobile locksmith arrives with a basic tool, tries to program a key or reset the immobiliser, and suddenly the car completely shuts down. No crank. No comms. No start. Just pure panic.

We call this the "Locksmith Kill" and yes, it’s real. We've become known for recovering cars that were left non-starting after a failed key or immobiliser job. In most cases, the ECUs or immobiliser data were corrupted, wiped, locked out, or incorrectly coded.

Of course, there are people out there with excellent knowledge, others with just enough to get by, and some who unfortunately leave behind more problems than solutions. These things happen and we’re here to fix them.

So if your car was running fine before someone “just tried a key” and now it’s a brick... don’t panic. OBDTech can bring it back to life with proper tools, logic, and MASSIVE experience.
