I dont have key to open door so alarm will not go off and the motor will not turn over

if key worn down may cause problems of no start as well as fuel pump --cam or crank sensors --have vehicle scanned may have pending code try a new key get one cut --as to door will need to notify dealer with vehicle and proof of ownership

See what happens when you put the key into the driver's side door, turn it left, then turn it right. That stops the alarm in Sables.

How to disable car alarm with out removing anything

Note this Fixya answer regarding a 2002 Marquis with manual transmission:
http://www.fixya.com/cars/t5592167-kill_switch

Try turning it off and on with out starting it 3 times and then try to start it fourth time

Best bet is to pay an alarm installer technician to kill the old alarm.

sounds like you also killed the immobilizer too, now are immobile.
CRANKS BUT DONT START right, and IMMO blinks ?
the IMMO light tells you ,what ITS doing, watch it.
the thieft and immo are very complex in the toy world.
before hacking it , find out how,.... the top answer is , you cant.
so which is first. the thieft sys. or immo.?
first read this, after checking all fuses in both fuse boxes

dont loose the master, key or use id daily
dont have 2 keys in car. at same time.
dont have other keys on right blocking the magic RFID key.
dont mess with it, if you mess with it , it THINKS you are crook
so dont.
it may also IMMO lock out if the theft system is hacked.
ill let you goggle that.

• If it is a stock alarm the you can put the key into the ignition and turn the vehicle over and the alarm will shut off. Often time just sticking the key into the drivers door is sufficient but the ignition will surely kill the alarm. It has to be the transponder key though not just a quick cut key.

• If you have any comments please feel free to leave them here.
• Hope this helps and thank you for using FixYa.

The 2003 Sonata is equipped with a 'starter KILL' burglar alarm system with disables the starting system (using a N/C 'contacts' configuration instead of a N/O contacts configuration). N/C=Normally closed, and N/O=Normally open contacts. When the alarm goes off with a MY Sonata, the only way to DISARM it is with the key fob (remote) originally programmed for it (unless you purchase a new remote & have it programmed for the vehicle at an authorized Hyundai Service Department). NOTE: So long as the keyless entry & burglar alarm system is functioning/operating normally, the alarm will keep going off and the STARTER KILL function will still prevent you from starting the vehicle. One option is left without purchasing a new remote and having it programmed.
1. When the alarm goes off, get into the vehicle and insert the ignition key into the ignition.
2. Turn the key to the 'RUN' position (NOT the ACC position) and wait for the alarm to STOP (usually about 3 to 5 minutes).
3. The engine should then start using the ignition key.

If this procedure doesn't work, the problem will need further diagnosis by a qualified/certified Hyundai Service Technician.

Hope this helps

Starting System
The function of the starting system is to crank the engine at a speed fast enough to allow the engine to start. Heavy cables, connectors and switches are used in the system because of the large currents required.
The starting system consists of a gear reduced starter motor, battery, remote control switch (ignition switch) and relay.
Vehicles equipped with automatic transaxle have a transmission range sensor attached to the circuit which prevents operation of the starter motor unless NEUTRAL or PARK are selected.
Vehicles equipped with a manual transaxle have a start inhibit switch in the starter control circuit, which prevents operation of the starter motor unless the clutch pedal is in the applied position.
------------------------------------------------------------------------------
The anti - theft protection system provides protection from unauthorized entry into the passenger compartment.
The system is controlled by an anti - theft alarm control. When armed, unauthorized entry into the vehicle is detected by lamp switches.
Once triggered, the system flashes the headlamps, the parking lamps, the alarm indicator, and sounds the horn. In addition, the starter circuit is disabled to prevent starting the vehicle until the system is disarmed.
System Arming
The system will be armed by the remote entry transmitter when the following input sequence is followed:

1. Turn the ignition switch off and remove the key.

1. Close all doors (unlocked).

1. Press the LOCK button on a transmitter to lock doors. Alarm warning lamp will turn on.

1. Wait for the anti - theft warning lamp to turn off.

The system will also be armed when the following input sequence is followed:

1. Turn the ignition switch off and remove the key.

1. Open a door. Alarm warning lamp will flash.

1. Lock doors with power door switches. Alarm warning lamp will now glow steadily.

1. Close all doors.

1. Wait for the anti - theft warning lamp to turn off.

Opening any door will activate the alarm after the alarm is armed.
Disarming an Untriggered System
The system can be disarmed by performing one of the following procedures.

• Driver or RH front door is unlocked with a key.
• Driver door is unlocked by pressing the UNLOCK button of a remote entry transmitter.
• If remaining in the vehicle, turn the ignition switch to ON or ACC position.

System Triggering
The armed alarm system will be triggered if any door is opened without using a key or a remote entry transmitter to unlock the door first.
Disarming a Triggered System
Carry out either of the following steps will disarm the triggered alarm system.

• Driver or RH front door is unlocked with a key.
• Driver door is unlocked by pressing the UNLOCK button of a remote entry transmitter.

Two minutes and 45 seconds after the system has been triggered, the horns and exterior lamps will shut off automatically. The system will then reset to an armed state and will trigger again if another intrusion occurs.
--------------------------------------------------------------------
Passive Anti-Theft System (PATS)
The Passive Anti-Theft System (PATS), known as SecuriLock, is fully passive in operation and requires no special procedures by the driver to arm or disarm the system. It is invisible to normal scrutiny and is operated by a transponder within the key body. This communicates with the module through a transceiver mounted around the ignition switch lock barrel.
The PATS functionality is incorporated within the powertrain control module.
PATS keys contain an electronic device inside, and are physically larger than a non-PATS key.
The transponder code reading is carried out when the key is inserted into the ignition lock barrel, and turned from position 0' to position II' or III' to crank the engine. If the PCM receives the correct code signal, the engine will start. Should the code received not be recognized, the engine will not crank as the PATS is still armed and the engine immobilized.
Anti-Theft Indicator
Whenever the ignition is switched on the anti-theft indicator will remain on for three seconds while the system carries out an initial ignition key-read.
The anti-theft indicator will flash rapidly for three seconds to indicate the PATS has immobilized the vehicle.
For additional information on the PATS fault codes, refer to the Diagnosis and Testing section.

Open the door, the alarm will sound , go under your dash, normally installation techs will install a kill switch or alarm override button either in the drivers side kick panel to the left of were your left foot rests or inside the fuse box panel, under the steering column or by the center column somewhere but most likely the drivers kick is the spot. So open the door and find the kill switch or override button and put the key in the ignition turn it to the on position without cranking and press or toggle the switch after you turn the key, this should override the alarm and let you start the vehicle, otherwise you have to remove the alarm main fuse from the brain and rewire your starter kill to factory so that you can start your vehicle normally again until an alarm tech corrects the alarm wiring.

Good luck my friend, hope it is helpful.

you have to find wich door is first becouse they all have kill swich in every door so u have to disconect one by one n by pass to see wich one turn the light off then u will have to replace it auto parts store shuold have these at hand, lol becouse as long the light stay on the alarm will not work,
