Alarm in a hyundaiexcel 1999 it wont turn off since i disconected battery

The factory alarm is located under the driver seat its a black box try disconecting one of the wires u cant take all wires off cause it wont start but if you disconect one i think the smaller wire you will be able to turn the car on and alarm wont go off anymore but you will have to manually open your doors good lick

Disconnecting the alarm prevents the starter from turning and the fuel pump from running. Gotta fix the alarm system.

it is just a case of tracing every wire from alarm unit and disconnecting from vehicle wiring, and reconnecting the vehicle wiring where it has been cut , send me the make and model and i'll try to get the wiring diagram ,make it much easier

try disconect car battery for 5 min to get alarm to reset ,then disarm alarm via the remote before opening door or turning the key to start <if you have alarm remote

direct to connect the battery with alarm system.

did it start before you changed the battery?when you say the alarm goes off do you mean the factory alarm or did you have it installed aftermarket? is there a theft or security light flashing inside?let me know maybe i can help

If the passlock has been tripped you have two options.

1) Disconnect the Battery for 30mins.

2) Leave the key in the "On" position for 20mins.

The starter is most likely fine, the problem is most likely with the alarm system. I don't know enough about the alarm system to help you though.

IF CAR DONT CRANK CAN BE THAT BATERY IS EMPTY, STARTER OR IGNITION SWITCH. IF ALARM SISTEM IS ORIGINAL TRY THIS: CLOSE ALL DORS AND HOOD, TRUNK AND LOCK AND UNLOCK PASENGER DOR WITH KEY. THIS RESET THE ALARM (IF BATERY IS DISCONECTED)
MARKO

disconect the battery for about 15 minutes and turn the head lights on after bat is disconected and then turn head lights off reconect bat and this should reset your alarm system.
