In the world of automotive diagnostics, the name Delphi DS150E (often referred to as Autocom or Delphi 2015/2020) holds a special place. While modern workshops have moved on to subscription-based J2534 passthrough devices and cloud-diagnostic tools, the DS150E remains a cult classic for locksmiths and DIY mechanics due to its low cost, wide vehicle coverage, and—crucially—its ability to perform key programming.
If you own a Delphi DS150E and want to move beyond reading and clearing engine fault codes to actually cutting and programming transponder keys and remote key fobs, this guide is for you.

Warning: Immobilizer work carries risk. If you interrupt the process or use the wrong transponder, you can brick the immobilizer, leaving the car dead until a dealer resets it.
