You can't if by 'take off', you mean bypass or disable it. The anti theft system is there to stop what you are trying to do, drive the car without the correct credentials, key chip to the ECM. Just reset it.

You can't, you have to fix the problem, not try and find a way around it. The anti theft system is there to stop exactly what you are trying to do. You can't reprogram the computers, modules and sensors.

Hi, im a retired ford tech, with alot of experience on ford anti theft . Now if you are asking about a built in oem factory anti theft, your not going to be able to bypass it. Now to answer your question, I would say your factory anti theft IS NOT causing your issue. It will make it unable to start,it doesnt kill anything else.

pull the fuse, and reinsert, if that doesn't work, take the neg. battery cable off to reset com. but that will also erase any codes you may need for a machanic in the future. good luck

replace brake pedal shifter interlock motor

The anti theft only keeps the car from starting, not moving. Make sure the brake lights work, check fuses.

the anty theft is not working right thats the part that locks the gear shift into park, you have two ways of sorting this out,
1 get the anty theft fixed
2 remove the anty theft from the gear shift,
