If You need to reset the anti-theft system on Your Ford F-150, You should be able to do so in one of two ways. It's possible to perform a soft reset by disconnecting the negative battery terminal for 10 to 15 minutes; however, the majority of anti-theft faults will persist through this. Therefore, it might be necessary to go a step farther, and perform the detailed reset outlined below. You'll need two progRammed keys to perform the reset. Put one into the ignition, and turn it to "ON". Cycle it back to "OFF" and remove. Immediately insert the second key (within 5 seconds) and cycle it to "ON" and "OFF" as well. Insert the original key back within 10 seconds, leave it "ON" for one second, and then cycle back to off. Do not remove the key until the security light turns on.

If you need to reset the anti theft system on a ford f150 you should : step 1 insert your first programmed key into the car's ignition and turn it to the "on" position. Step 2 cycle the first key back "off," remove it from the ignition and insert the second programmed key within 5 seconds. Step 3 cycle in "on" and "off" and then remove the second key. Step 4 insert the key you would like to reset within 10 seconds, leave it "on" for one second and then cycle it back to "off." Leave the key in the ignition until the security light turns on, then remove the key to complete the programming process.
