Horns blares continuously when key is removed from ignition!
My 2004 Ford Explorer was working fine all morning until at one place I needed to stop I removed the key from the ignition and the horn blared constantly! Upon putting the key back in and turning the ignition on, the horn goes off. I can turn the car off and all is quiet until I go to remove the key from the ignition again and once more the horn blares continuously... My workaround is to just leave the key in the ignition, but this is not great for security... (I can lock/unlock the doors using the numeric keypad on the driver's door). I've tried locking/unlocking the doors using the keypad and using the key but to no avail...the horn just does not shut off until the key is reinserted and ignition turned on (then back off). H--E--L--P!!

No trick to it. It should not be happening. I would disable the horns right at the horns themselves until you get the vehicle started and the battery charging up. Then you can deal with the horns. An electrical genius may have to diagnose it. New car problems are bummers.
Your horn relay may be shorting out, making your horn operate all the time. Have a look at your relays. You might find the horn relay is the same as another relay, If it is, try swapping relays with a known good one, and see if the horn operates normally. If so, get a new relay. Good-Day!
I had this same problem with a car I was driving out in 'Frisco. What a pain! The problem was a short in the horn button on the steering wheel. The dealer demanded replacing the horn button, which was PART OF THE AIR BAG ASSEMBLY, AND THAT COST 1.,000 DOLLARS! After intense arguing, warranty covered it. If I was faced with this, I get me a blow dryer for your hair and position it to blow inside the back of the steering wheel on LOW heat, so as not to melt the plastic, for about 6 hours. Anything you can do to dry out the inside of the steering wheel should help. Be blessed.
As necessary, remove all under dash panels in order to gain access to the ignition switch.
As necessary, lower the steering column to gain working clearance.
Disconnect the ignition switch electrical connectors.
Remove the ignition switch retaining screws from the studs. Disengage the ignition switch from switch rod. Remove the switch from the vehicle.
Position the lock cylinder in the LOCK position.
To set the switch, position a wire in the opening in the outer surface of the switch through its positions until the wire drops down into the slot.
NOTE: The slot is in the bottom of the switch where the rod must be inserted to allow full movement through the switch positions.
Position the ignition switch on the column studs and over the actuating rod. Torque the retaining nuts to 40–64 inch lbs. (4.5–7.2 Nm).
Remove the wire from the slot in the housing. Continue the installation in the reverse order of the removal procedure.
go on ebay to by the key and then get it cut at like target or walmart...
once you get the new key...
1-insert and remove key from ignition two times
2-close and open driver door two times
3-insert and remove key once from ign.

6-turn key to on (not start) then off, twice this is rewrite mode
7-remove key from ignition,the door locks should cycle twice.if not start over.it may take a few tries.
8-press lock/unlock together and hold for a second

confirming program.continue to do other remotes you have,steps 8 and
9.if only one in possession,you are done. To end mode open door or insert key into ignition.
You'll need to follow the steps with no more than a 1-2 second delay between each step.. hope it works
A FORD MACHANIC HAS TOLD ME THAT IN FACT THE KEY HAS TO BE RECODED. MY SITUATION IS EXACTLY THE SAME. HE SAID TO RECODE THE KEY I HAD TO TURN THE IGNITION TO THE RUN POSITION, THE SECURITY LIGHT ON THE DASH WILL FLASH RAPIDLY AND CONTINUE TO FLASH FOR 15 MINUTES . WITHIN FIVE MINUTES AFTER THE LIGHT STOPS FLASHING I MUST TURN OFF THE IGNITION FOR ONE SECOND AND TURN IMMEDIATLY BACK TO THE RUN POSITION FOR 15 MORE MINUTES. THE LIGHT WILL GO OFF AGAIN . WITHIN 5 MIN. I MUST TURN OFF THE IGNITION FOR ONE SECOND AND TURN BACK TU RUNNING POSITION. 15 MINUTES LATER REPEAT STEPS AGAIN AND THE KEY WILL BE REPROGRAMMED, AND STSRT THE CAR. GOOD LUCK MY CONTACT IS A FORD MASTER MECHANIC.
