These Fuses power the PCM:
Fuse 2 & Fuse 30 located in the Central Junction Box
Fuse 18, Fuse 23, & Fuse 24 located in the Battery Box
why not just disconnect the Positive Battery Cable

please post ALL information when asking a question, as we cannot see the vehicle or what you are doing.

IF you only have "one" Ford Key, & the "THEFT" Light is flashing, then the Key was NOT Programed as a "Master Key"
You will need use of Ford Scan Tool to Program the Key as "Master Key" so this issue will not happen again.
You also may want another Key Programmed at the same time.
Some Shops or Mobile Locksmiths can do this, but Ford Dealer is best choice
apprx 1 hour labor
There is no other way to fool computer or Program, without the use of Ford Scan Tool or Equal, that can Program Key
