Course description


In recent years multiple transponder tool makers offer locksmiths a new opportunity in automotive key making, often known as an ‘EEPROM solution’. Rather than relying on a diagnostic tool to program new data into a vehicle immobiliser or ECU (which may inherit restrictions), the EEPROM solution employs the vehicles existing transponder information and manipulates it to produce either a new or duplicate key.

Purpose of the learning program

This one day course provides theory and practical training elements for locksmiths and automotive tradespeople in modern key making techniques, manipulating data inside an EEPROM found in the vehicle’s immobiliser or relevant ECU. The skill set is also applicable to several forms of ECU repair and second-hand parts replacement. It will provide candidates with the knowledge and practical skills required to convert various early transponder and main ECUs back to factory status, and enable users to write new transponder information into an existing ECU. The outline has been designed as introductory for automotive locksmiths already experienced in diagnostic key programming, who have little or no prior knowledge regarding eeprom reading and ECU resetting.

Program candidates will develop a basic understanding of eeprom package memory functionality together with methods of identifying, reading, analysing, writing eeprom data files (.bin). The program involves both theory and practical elements.


To apply, applicants require prior experience regarding:

  • Significant diagnostic key programming experience
  • Basic to fair PC operating skills

Learning outcomes

Upon completion of the course you will gain the ability to provide new key solutions for various vehicles not applicable for diagnostic key programming, achieved by manipulating the immobiliser data directly inside a vehicles immobiliser or main ECU. The knowledge and skill sets acquired will also provide an opportunity to discover restricted pin codes from some immobiliser systems which may otherwise not be available from the dealer.

Yours to keep

IMPORTANT NOTE: this training course previously featured the Wellon VP-390 universal programmer which has now been superseded by the VP-598. The new Wellon programmer is not working sufficiently for many of our applications. Proceeding comprehensive testing Tech Ed made the decision to migrate to the Scorpio-LK Orange5 programmer. 

For further explanation on the matter refer to this document.

The included equipment is now available in two optional formats. Select either the Orange5 basic kit format (which may be upgraded later at an additional cost), or upgrade now to save doing so in future and include the Orange5 FULL immo HPX kit.

The Orange5 basic kit will cover any eight lead serial memory device featured throughout this introductory training and much more. For more information about the programmer, click here

The Orange5 FULL HPX immmo kit includes all relevant adaptors for immobiliser EEPROM programming, covering eight lead memory devices and many other MCU and FLASH memory devices for advanced users. Many of the additional adaptors require the user to de-solder and solder memory devices from the target ECU. For more information about the programmer, click here

If you are unsure which kit you would prefer, select the basic kit which can easily be upgraded in the future.

Included into the kit and training fee:
