Disconnecting anti theft system emobiliser

Hey guy I'm new here and just might be in the wrong place but anyway i have a 2002 BMW 325i and my 1yr old daughter got to my keyring and banged my keys on my marble floor really hard and broke my key fob open I caught her teething on my ky-fob chip that actually goes in the key now I currently have a no start/no crank situation going on now anybody knows how to disconnect or disarm the anti theft system emobiliser so I could just start my car with just my half of key without worrying bout the chewed up chip that was in my key fob.

You can do it, but it isn't simply just unplugging the EWS. You also need to reprogram the DME and jump the EWS wires so it sends power to the starter
