Immobiliser Problems
 

Hi all new on here, having some problems with my 2003 STI, had a coolant issue a few weeks back so got recovery home, the car drove onto the truck fine but when I got home, I couldn't lock/unlock using the fob so I can't disable the immobiliser, car locks and unlocks fine with the key itself but just can't get it started, anyone got any ideas how to resolve this?

Good luck.

Did you try a new battery in fob?

Yeah mate tried a new battery and spare fob too

I hate electrical gremlins, I've just been through 2 weeks of my jdm legacy not wanting to start on occasion.
kept getting error codes on dash.
I bought new battery .
turned out it was the speed converter that was fitted behind the Speedo.
It had been in there for 3 years no problem.
removed it and starts fine now.
You could try disconnecting the battery overnight.

I take it that it has the standard sigma alarm fitted?
Do you have the overide pin number?

Yeah it Still has standard alarm system, unfortunately I don't have the code for it, would subaru have a note of the code by any chance?

It's a nightmare! I'll try disconnecting the battery and seeing if that helps it

Yes they will have providing that a previous owner hasnt changed it.
