If you think the EWS delete is necessary, I'll help. It worked great on mine. If you install a fused kill switch, then you don't have to worry about someone using a screwdriver to start it.

Do you suspect the key electrical ignition part? I have an OEM one not being used. I can send it to swap out. I don't think those need coding. I swapped mine out trying to chase a parasitic drain.

I have a PDF to email. It details EWS testing. If you order the EWS deleted DME, only one more mod is needed. A fuse needs to be trimmed to fit the EWS plug. I used small snipers to trim it. A file will work too. Only edges need trimming. You can install a kill bypass switch there.
