Hello, I have a question about a 2008 Mazda 5 immobolizer.

I had the car for a while then my AT light when on, the diagnosis from the shop said it was solenoide A . Paid 700 to get it changed.

A few days later, light was back on. After a few more diagnosis, the mechanic came to the conclusión it might be the ECU.

Changed the ECU but it was bought from a crashed Mazda and the immobolizer was on... Put my ECU back, now the immobilzer is activated and I have no idea how to fix it. I do have some knowledge on cars, I tried everything. I cannot afford dealer, they´re trying to charge me way too much

Any fixes?

Thank you .

 

A lot of locksmiths can program them now. Call around and see. Usually less than $100.00
