2005 Hyundai Tucson alarm will go off while locked and in driveway. Will stop bleeping if key is in the ignition. Only does this occasionally not constantly. Clecked all doors, hood and tailgate. What else should I check.
Make sure all doors are really closed and the door sensors are not falsely telling the alarm module that its open. if not then its the shock sensor in the alarm module acting up

When a battery starts to go bad it will set the alarm off constantly. Check the date on your battery and if it's between 3 and 4 years old most likely this is the cause. I had it happen before.

If the car is parked on a flat surface, and a potential liquid spill has occured in the gear selector, make sure the car is engaged securely in park.

hi from uk please try this ? with key removed try gently turning steerwheel to the right if you feel a slight spring in steering ? hold on the spring and insert key it should work and release lockand turn ign on ? if steering is springing on left ? try as above the same method not unusual for steer lock to prevent turning key as the steering even in straight position ? the necessity to gently release load on lock is req'd to allow key to turn/unlock the steering lock from the steering column practice doing the above each time you fit key to unlock steering and tuning ign on to start hope this helps
SOURCE: 2005 hyundai sonata--car locks itself with keys in
I own a 2005 Hyundai Sonata as well and this has happened to me. All the doors automatically lock as I pull on the door handle to get back in the car. This happened twice in the winter of 2007-2008, then it didn't happen again until this past December 2009 and now today in January 2010.
I wonder if it has something to do with cold temperatures? Or maybe that's when I'm more likely to leave my keys in the ignition with the car running!
But it is a big pain, one time my two year old was in the car and the fire department had to come pry a door open! I started carrying the box with the unlock button in my coat but even this would not unlock the doors this morning. Only the spare key will do.
I am taking my car into the dealer to take a look. And I'm going to write a complaint to Hyundai. This is unacceptable.
