Battery died, now horn alarm won't stop
 

So my battery died. I jumped it once and got it going. A few days later it died again. When I tried to jump it it wouldn't and the horn alarm started going off and continued everytime I tried to turn it over. I spoke to a mechanic and he thought a new battery would solve the problem. Unfortunately it didn't when I replaced battery, it is still triggering the horn alarm..

Anyone know what the heck is going on. I have a lojack that I try to turn off but I can't seem to. I'm not even sure its the lojack going off. I believe its the horn alarm if that makes sense.

Any assistance would greatly be appreciated.

Since the new battery have you locked and unlocked the car with the key?
If not try that.

You're a genius!! Thank you.

did you get this sorted I have the same problem
