Module Repair & Programming

When a key won't program or the car won't recognize any key, the problem is often the module, not the key. We repair, clone and program the electronic modules that control your car's security, with deep expertise in BMW, Mercedes-Benz, Audi, VW, Bentley and Lamborghini.
  • BMW CAS / FEM / BDC
  • Mercedes EIS / ESL
  • Audi & VW immobilizer
  • ECU & BCM cloning
  • Instrument cluster adaptation
  • Push-to-start repair

BMW CAS, FEM & BDC repair

BMW's CAS (Car Access System), FEM and BDC modules store key data and control starting. Water damage, failed updates or a dead battery can corrupt them. We read, repair, back up and re-sync these modules so your keys work again.

Mercedes EIS / EZS & ESL repair

A Mercedes that won't turn the key or shows 'steering lock' errors usually has a failing EIS ignition switch or ESL steering lock. We repair or replace and program both, and supply new FBS3/FBS4 keys.

VAG immobilizer & cluster work

Audi, Volkswagen, Porsche and Bentley store immobilizer data in the instrument cluster or a dedicated module. We handle component protection, cluster swaps and immobilizer adaptation.

ECU & BCM cloning

Replaced an ECU or bought a used module? It must be married to your car. We clone and adapt engine and body control modules so the car starts with your existing keys.
