DIAGNOSIS BEFORE PARTS

Find the Fault Before Replacing Parts

A key-not-recognised, immobiliser or steering-lock warning does not automatically mean the key is faulty. We identify which part of the vehicle security system is responsible before recommending replacement or programming.

SERMI-approved operator Legitimate access route to security-related repair information from participating manufacturers.
Multiple programming platforms Manufacturer systems plus Autel, Advanced Diagnostics, Abrites, Xhorse, Launch and other specialist tools.
Mobile to the vehicle Home, workplace, roadside, garage, recovery yard or trade premises where the procedure can be carried out safely.
Beyond key cutting Immobiliser diagnosis, module commissioning, coding, synchronisation and selected ECU/BCM work.
Why OEM Key Specialists exists

When Standard Key Programming Isn’t Enough

Some vehicles can be handled with proven professional locksmith programming. Others require online authentication, manufacturer security access, software downloads or control-unit commissioning.

OEM Key Specialists selects the appropriate programming route for the vehicle — using professional locksmith equipment where suitable and manufacturer procedures where required.

The vehicle determines the programming route — not the tool in the van.

The Right Programming Route for the Job

Depending on the vehicle, that can mean:

1
Official manufacturer software Secure online programming, coding and commissioning where supported.
2
Professional key programming Proven diagnostic procedures where the manufacturer route is not required.
3
Bench / module-level work Supported EEPROM, immobiliser, ECU/BCM and synchronisation work.
4
Security verification Identity and vehicle-authority checks where protected access requires them.
Manufacturer-specific capability

Key & Module Programming Using Manufacturer-Level Systems

Official or manufacturer-level diagnostic routes are used where the vehicle requires them, with the exact process determined by model, year and security generation.
