From my experience, the halo is what detects the rf signal from the head of the key. the halo (or transreiver ring) is located around the key cylinder. it could be malfunctioning. also, some keys have a capsule inside them that generates the signal. i have seen some keys where the capsule falls out. do you have another key and does it work. do you have a remote start system on your truck? hope this helps

Your ignition switch(were you stick the key to start it) has probably worn down or maybe the key itself has worn down but either way with anti-theft if the key doesn't match the cylinder right then it thinks it's being stolen.

I have a 2008 ford ranger xlt 4x4 4.0 . changed the motor and the battery was disconnected . now the truck will not start cause the anti theft is locked what do i do ???


Ensure you have "ALL" the wires connected and a fully charged battery. Then use your remote to turn off the anti theft devises and your truck should start with no problems. You may have to switch the anti theft device from your old engine to your new one or take the vin of the new engine to the dealer and get the code for that engine.

My 2003 ford rangers 4x4 4.0 anti theft system wont go off is there a reset button


A factory anti-theft system does not have a reset button.

Have you tried a different key?

Turn ignition key and motor starts up, next day turn ignition key and motor just turns over and wont start. could it be anti theft problem its a 2002 f150 4 wheel drive with 4.6 liter


This could be caused by either a faulty Crank Shaft Position Sensor or the anti-theft system. Try put key in, turn to ON position for EXACTLY 10 minutes, As SOON as anti-theft light shuts off or stops flashing, then IMMEDIATELY start the engine.

How do you reset the anti theft system


Try disconnecting your battery cables then wait about 10 minutes. The computer should reset itself. Reconnect the wires to the battery. It is normal for the theft light to blink about every 5 seconds when the ignition key is out or in the off position. This means the system is armed and working properly. Hope this helps. God bless!
