Fors escape ecm won't crank or start

Security system is in full lockdown, so if doing the key thing listed in the owners manual didn’t work then you need either a smart locksmith(if you have one in your area)or the dealership to do a total reset of the security system. Then hope the programmed ECM was done properly.
