When i called our dealer about the problem with the theft alarm in our 2007 Santa Fe going off for no reason (usually in the middle of the night), the dealer sounded not at all surprised and commented "oh, it just requires a simple wiring fix". I brought it in and the did their fix, and have had no problems since (a month and counting).
Same problem here but with a Toyota Sienna '99. It took $600 in diagnostic work but the problem was a low voltage electrical short in a switch that was part of the passenger door lock. Specialty shop found it by placing voltage testing equipment on 4 to 6 wires at a time that ran into the cars computer. They recorded any voltage spikes over all these wires 24hrs/day over 3 days to find the bad switch. Snipping the wire to that switch meant the alarm would always go off if the locked car was opened with a key in the passenger door lock but we we're ok with it. Car was about 5yrs. old when this ocurred but we never had another problem of any kind with it for another 4 years. Thanks, Dan

Normally you can't, it is there to stop exactly what you are trying to do. You can't disable it or bypass it, you have to fix the problem, not find a way around it. The anti-theft system is very complex and programmed into both the Body Control Module, the Engine Control Module and various sensors. It is better to go to an auto electrician, or an alarm / radio installer to fix the issue, which is a lot cheaper than the dealership.
Having said all that, they is a simple fix to disable it in this link.
It is on a system that cannot be disabled. The siren has gone bad and needs to be replaced. Check your dealer for a new siren. The odds of finding a good one in a salvage yard are very slim.
well the only thing that states about a anti theft alarm, in my manual, is if you leave your key in the ignition, and open the door it will sound a buzzer, to remind you that you need to remove your key, this is on page #114, nothing else is mentioned about this sorry not much help.
THATS WHY THEFT SECURTY ALARM GOING OFF THEFT SECURITY SYSTEM NOT WORKING FUSE IS MISSING.MORE LIKELY THE GUY SOLD YOU THE CAR BECAUSE OF FAULT IN THE THEFT SECURITY SYSTEM, GOING COST TO FIX.
I would recommend replacing the alarm control unit. This black plastic piece, located somewhere in the left kicker panel not only handles the sound alarm, but the flashing alarm, the keyless power locks and the theft code for the radio. It is rare that these boxes fail, more than likely a rusty sensor at the doors, trunk or hood will be the culprit. Mine goes off when cats go under the car, and cant figure why. Im making a decision on fixing the alarm, or fixing the cats.
Sounds like it went into theft mode when you unhooked the battery and tried to start it multiple times. Most cars have some sort of SKIM key which is a key with a computer chip in it that is programmed to a module in the car. If this programming is lost by a battery diosconnect it usually needs to be reprogrammmed by a dealer. The reason it won't start is because the theft mode probably has the fuel or spark disabled as a theft deterrent.
did you replace the fuse.if so try to get the alarm reset location,it could be in the stupidist place like my pathfinder you have to put the key in the tailgate and turn it to glass side and hold it for 20 seconds.and then hit the hidden reset switch under the rear carpet.
Hello, I had the same problem with my 2001 Maxima. The dealer suggested new key fobs, but the eventual fix was the car battery. When the battery is on the way out, the voltage drop is enough to set it off, just as it would if there was a voltage spike when someone breaks in. I have no problems now!
