Alarm keeps going off, can it be disconnected without disabling the vehicle/

Anti-theft system can keep vehicle from starting , Alarm is for vehicle content theft , open door without key alarm sounds (horns) ! PATS - passive anti theft system PATS enables and disables the engine from starting ,it will not cause the engine to die ! You have some other kind of problem ! If the vehicle engine doesn't turn over an red light on top of dash flashes fast ,then you have anti-theft system problem !
PATS differs from the perimeter anti-theft system in that PATS enables and disables the engine from starting. If equipped, the perimeter anti-theft system protects the perimeter of the vehicle (doors, hood and trunk) and sounds an alarm.

Mostly you can't as the alarm and immobiliser is integrated into the vehicle/engine management system.

It might be possible to disable it by getting at the software if you have the skill and a laptop with the right programmes but other than that disconnecting the sounder is all that is possible.
Some of the earlier Ford alarms were operated by a separate module that could be disconnected. Unfortunately these were hidden behind the dashboard and impossible to reach without first removing the dashboard.

You must have a spare key. When your alarm is going off have your key in the ignition, wait it out. When your alarm stops in approximately 30 seconds keep the key in the ignition exit the vehicle and lock the doors (don't forget your spare key). Go to the passenger door with the spare key and unlock the doors and turn the key that you left in the ignition and it should start right up. Just worked for me.

{: ) When armed, the content theft deterrent (CTD) system is designed to deter vehicle content theft by pulsing the horns and exterior lamps for approximately 30 seconds when an unauthorized vehicle entry is detected.

An unauthorized entry can be any of the following with the CTD system armed:
• When any door is opened without first being unlocked using the keyless entry transmitter • After a battery reconnect, if the battery was disconnected with the CTD system armed Disarming an Armed System/Silencing an Alarm
If system arming has been requested by the power door lock switch or the keyless entry transmitter, it must be disarmed.
Important: Using the power door unlock switch or manually unlocking the doors does not disable the content theft deterrent (CTD) arm mode. Also, disconnecting the battery or pulling fuses does not disable the arm mode, since the BCM stores the CTD mode status in memory.
• To disarm the CTD system in standby mode, perform one of the following: - Press the UNLOCK button on the keyless entry transmitter. - Insert a valid key into the ignition and switch to the ON position. • To disarm the CTD system in the armed mode (non-event) or when activated (during an alarm event): - Press the UNLOCK button on the keyless entry transmitter. - Insert a valid key into the ignition and switch to the ON position Locking the Vehicle Without Arming the CTD System Locking the vehicle may be accomplished without arming the content theft deterrent (CTD) system. Use of the manual door locks or using the key to lock the doors will lock the vehicle, but will not arm the CTD system.

When the alarm goes off, it disables the starter circuit. You'll want to have your key fob (remote) checked for proper operation at an authorized Hyundai Service Department. If you inserted the new battery in backwards, the remote will not work. It also needs to be the remote originally programmed for the vehicle.

chop it out / the alarm system is wired paralel / here's a site that will help ( www.the12volt.com ) good luck

I am having the SAME problem with my 99 Corolla, Still searching for a way to disable the factory security system, for the last two years I have the vehicle hotwired through the headlights to start it. (1 wire to battery positive, 1 wire to starter hot lead, touch them together.) unfortunately this has proven very dangerous as the vehicle will start even in gear, and take off without a driver. additionally, because the alarm is going off continuously, the battery dies if not disconnected after every use. I found the fuse in the relay box that disbles the alarm, and the car starts fine, unfortunately, It it also the fuse for the alternator, so that solution will not work either. If anyone has found true way to disable the system, PLEASE offer your suggestions!

Just pull the one under the hood at first. The vehicle should not be running when you do this. Glad I could Help.

if you disconnect the brown earth wire from the alarm hub it will disable the alarm

I would say you have two options, You can take it to the dealer and have it disconnected, or you can go to an aftermarket car stereo/alarm store they will install an aftermarket alarm and disable your stock one at the same time, for probably about as much as the dealer would charge to just disable it. First just call the dealer to get a quote on how much that would cost, and then call the alarm place and get a quote.
Thanks,
