Exclamation Help! Anti-theft System Not Working...I'm Stuck at Work!


I have a Ford anti-theft system on my í03 250 7.3L. I donít know if it was installed at the factory or the dealership, but it has an alarm horn on the driverís side of the firewall and has a big FORD sticker on it so I assume it is OEM or a dealer option (and it has a little l.e.d. light on the dash just left of the steering column which a button too). It only came with one remote so I bought another and reprogrammed them both (about 2 weeks ago).

Hereís my problem: I canít get the truck to start if I donít use the remote to disarm the alarm (this was happening before reprogramming the remotes too). With my old F-150 if I unlock a door and open it the anti-theft would automatically disarm and the truck would start. If the alarm would sound anyway all I had to do was put my key in the ignition and turn it to Ďoní to disarm the system then I could start my truck. Not so with my F-250. If I unlock and open the door the dash light blinks once ever 1-1Ĺ seconds (the light also does this if I take too long to start the truck after disarming it). Iíve tried everything I can think of with the key in the ignition (and pushing the button too) to try to disarm it without the remote. Nothing works. I even found a post that said I need to turn the truck on (but donít start it) for 45 seconds, turn it off for 10 seconds and turn it back on for 45 seconds. This only worked to make me feel like an idiot (the light is still blinking).

My concern is that I wonít be able to get home tonight after work (my remote worked this morning but is on the fritz now).

Does anybody know how to manually disarm this *insert expletive here* system without the remote? So far two Ford dealerships donít know. Iím hoping somebody has shared this frustrating experience and will show pity on me by saving me the agony of having to spend the night at the office or, worse yet, riding home with a co-worker!

Thanks for any help.

Send a message via AIM to lifewitlooie
start cutting non-important wires that lead to the alarm and see what happens. maybe it runs through a "not so important fuse" that could be taken out.

Thanks lifewitlooie for the response but I decided to put the option of setting a Sawzall loose under my hood towards the bottom of the list of possibilities.

After a grueling anxiety attack about carpooling after work I finally calmed down and (swallowing my pride) called the Ford Service Department at another dealership. Here's what I've learned over the last few hours:

The anti-theft system cannot be disarmed without a remote. The Ford Service “Specialist” told me that my remote may have lost my program. Apparently sometimes this just happens. Use the following procedure to reprogram your remote(s). If you’re stuck, like I was, you can reprogram the one you have, but you must program all the ones you want in the same session. So when you get home you’ll need to reprogram all the ones you want since they won’t function now. You can have up to 4 programmed for a vehicle at a time (also, I read when you do this make sure that all of your locks are either up or down when you start).

I don’t know what years this is good for (I have a 2003 F-250), but the Ford guy didn’t ask me what year or model I had so I assume this would work for a wide range of years. Here’s how you reprogram your truck remotes:

1. Insert a key in the ignition and turn from OFF to ON eight times in rapid succession (within 10 seconds) with the eighth turn ending in the ON position.
2. The doors will lock/unlock to confirm that programming mode has been entered.
3. Within 20 seconds, program a remote transmitter by pressing any button on a transmitter. The doors will lock/unlock to confirm that the remote transmitter has been programmed. (If more than 20 seconds pass before pressing a remote transmitter button, the programming mode will exit and the procedure will have to be repeated.)
4. Repeat the previous step to program additional remote transmitters. The doors will lock/unlock to confirm that each remote transmitter has been programmed.
5. When you have completed programming the remote transmitters, turn the ignition to OFF or wait 20 seconds. Again the doors will lock/unlock to confirm programming has been completed.

If that doesn’t work, check the battery. Use something strong and thin (like a knife blade or flat-bladed screwdriver) to pry open the remote. Make sure the battery looks like it’s in good condition and that the tabs are making contact with the battery. Since a new CR2032 battery is only a couple of bucks you might as well replace it while you’ve got it open.

Snap the remote shut and try it again. If that fails, try to program it again. If that fails I can’t help you, you’re more screwed than I was (I had a dead battery).

An interesting piece of info I also learned is that if you cycle the ignition switch from OFF and ON three times that puts the anti-theft system in valet mode (disabled). To return the system to normal (enabled) all you have to do is cycle the ignition switch from OFF to ON three times again.

Sorry it’s so long-winded and I hope this helps the next person who gets stranded at work so they won’t have to mooch a ride home with a co-worker!
