DE is for a door lock error and you will need to replace the lock. Here is the part to order.

have you tried the door locks, enter the car and lock and unlock doors, the alarm is actived with remote or key when door lock is locked, how do you enter the car?

check the fuse and relay if both have power check for power at master door lock swich if power is good there change swich

Either you have a bad door jamb switch or the interior lighting circuit ground side is shorting somewhere. Start by checking the drivers door jamb switch for short or wire rubbing thru to metal.

check for loose connection on the door sensor or micro switch you ay need to change the micro swich if faulty

Right , here's your problem ,,, the door swiches are incorperated into the door locks and thats why your interior light does not come on, therefore the vehicle thinks the doors haven't opened, This will cause the alarm to recycle the door locking signal .

could be bad door locking swich or possible failing relay

Make sure window lock swich is in on position.If needed check the fuses.
