How can you eliminate a Lucas 5AS, 10AS or ALM Immobilizer?

You are an owner of a
  • Classic Mini
  • MG-F or TF
  • Rover 200, 400, 600, 800 etc. (also with HONDA PGMFi Engine)
  • Lotus Elise with Rover K-Series Engine
  • LandRover Defender, Discovery or Freelander
  • Morgan with Rover Engine
  • Caterham with Rover Engine

and you are suffering from Problems with your Lucas 5AS , 10AS or ALM (black version of 10AS) immobilizer?
You can disarm it only rarely or not at all?

The Keyfobs , the immobilizer or both will fail earlier or later. A replacement is near to impossible to find or very expensive nowadays.

There is a replacement module which is installed instead of the 5AS, 10AS or ALM/CH12 and behaves towards the Engine Control Unit (ECU) like a disarmed immobilizer. As a result you can reliably start your engine from now on without using your keyfobs.

Our module is ´Plug-n-Play´. No soldering and no searching for cables. Simply  plug onto the existing connector, replacing the Lucas 5AS immobilizer. Pug-In is done within a few minutes and we offer a lifetime warranty.

For those who would like continue using the central locking functionality, we offer our module fitted into the immobilizer (Typical for 10AS & ALM).

In case you would use our service, please send your 5AS, 10AS or ALM Immobilizer together with the keyfobs to:

Ing.-Büro Grafe
Ralf Grafe
Hammersteinstr. 3
47807 Krefeld

Reading codes and production of your individual module is typically done within one working day.  Payments can easily be made using PayPal.
