Replace the door latch inside the door. But look up and see if you can just get the sensor for security. They have finally started to sell them separate.

At one point the door was lock from the in side and then closed and then unlocked with alarm, try un-locking it from the drivers door, then from the in side push the un-lock button and then close the drivers door. U should have no problems with it, but they do say that putting the key in the ignition and then do what you would like starting it but don't and do it 2 times and then start it will tell the alarm that it is not stolen.

Do u know that key less entry code to your drivers door?
Let me know if you would like your code that is if you don't know where to look.

SOURCE: alarm problem on my 2001 elantra

This alarm system can only be 'disarmed' using the keyless remote programmed for this specific vehicle. Press the "Unlock" button on the keyless remote -- this resets/disarms the alarm system. If you do not have keyless remote for this vehicle, get one and have it programmed at a Hyundai Service Center. Problem solved.

Disarming an Armed System/Silencing an Alarm
If system arming has been requested by the keyless entry transmitter, it must be disarmed.
Important: Using the power door unlock switch or manually unlocking the doors does not disable the CTD armed mode. Also, disconnecting the battery or pulling fuses does not disable the armed mode, since the BCM stores the CTD mode status in memory.

To disarm the CTD system in arm pending mode, SECURITY indicator flashing and doors open, perform 1 of the following:


-
Press the UNLOCK button on the keyless entry transmitter.


-
Insert a valid key into the ignition and start the vehicle.

To disarm the CTD system in the armed mode:

Voyager ignition key in the ignition look under the dash there should be a little red button its just small small micro switch that should be the disabler you turn the ignition on with the button in okay now you disconnect the battery to charge it and once fully charge then you can go ahead and play with the alarm circuit but I've found if you take the ignition key put it in the drivers door you unlock the key and you hit the unlock button you lock the key and you hit the lock button then you unlock it but

I have a 2005 JGC 5.7 hemi and sometimes remotes wont work only when you want to unlock it.If you use the key to open door alarm sounds. what could be the problem?


Have you tried a new battery in the remote, or do you have a second remote you can test. Either your remote is worn out or the battery is dead.
Once you lock the car with your remote it will active the alarm and if you use your key it won't deactive the alarm only your remote will, on some cars putting the key in the ignition will deactive it.
If you can deactive your alarm with your remote and can just manualy lock and unlock your doors and that should prevent your alarm from going off until you get a new remote or battery.

You need to find the black push button called the valet button. That is the overide. Get in the car turn the key to IGN as the alarm is going off and then you have either 5 or 10 seconds to push that button once and then 2-5 seconds later the alarm is shut off. To put the car into valet mode which means no alarm at all you put the key to IGN push that button once then pull key out at which point the blue light should turn solid blue.

Or option two is you open a door and hit the lock, then unlock, then lock button again on the remote and the blue led will be solid which means no crazy alarm.
