Disconnecting the battery probably did reset a module, so the system is working again.

My Fords have the red light blinking when they are not running.

you all are the best. thank you !!!!! a ford dealer's mechanic was talking about diagnostic fees $180.00, and if it is not working properly the truck will not let me start it and they would have to tow it. UH HUH. then i got to thinking "i think the light SHOULD be blinking when the truck is off and when im out of the truck to let me know the alarm is actually working. another mechanic told me to leave the chip keys in the truck and the computer would "learn" that i am using the proper keys. and stop blinking. UH HUH.THANKS AGAIN !!!
