Default 2008 Mazda 3 Anti theft won’t disengage

Did work on the Mazda over the weekend

changed out the water outlet coolant flange

and once had it all back together

it started everything seemed alright

then the AT light came on and now I can’t even turn it over

But there is power , radio and everything works

Just no crank

wondering what I did wrong everything is properly hooked back up

was thinking maybe the ecu got wet and tripped the anti theft


any help would be great

just have standard keys is then lock sequence I have to do ?

thanks

Did you depress the little button on the bottom of the dash, left side of the steering column? This is how we bypassed it in my son's car, exact same issue.

I don't, no. My son's car isn't here right now. It's a small black button underneath the dash by the OBD2 reader port beside the steering column. It should be the only button down there. He has the alarm system installed by the dealer when the car was bought new however (previous owner), so it may be different if it's an aftermarket security system.
