Security alarm goes off when unlocking the driver's side door.

Your Car is equipped with an Electronic Security System. If you disable it (which most probably you can not), you will bet on security of your car. If you still want to disable it, you should contact your Dealer or Authorized Service Station with Purchase Bill. If possible, they'll change locking system to old one.

Unlock the passenger door first and see if the problem still exists. If so, the doors lock and unlock sensor will likely need to be replaced. The vehicles security system is not getting the unlock signal when you unlock the door. Hopefully, the passenger side is still working.

the valet key doesnt have a transponder chip in it, so it will allow physical turning of keyways and operations, but will not disable the alarm and often wont disable the immobilizer.

sorry to say i think you will need to get an autolocksmith , or main dealer to get you a functioning key with transponder chip mapped to your cars rfid system that will allow alarm to be enabled /disabled

Sounds like the security system is armed. It is designed to disable the starter. If you don't have a key fob for the alarm, try locking and un-locking the driver's door with the key to disarm. If that doesn't work, look for a very small black button or toggle switch that will either be taped to wiring under the driver's side or the dash, or mounted to the very bottom of the dash above the driver's legs.

Insert the key into the door lock on the driver side and move it to the unlock position two times quickly. That should turn off the alarm.

I know a quick fix to get it started but you might think i'm crazy to do this:

My 2003 Dodge ram van 1500 does the same thing. I put a small heater on the driver's side floor blowing the hot air toward the door.
I plug in the heater when I get home from workand let it run all night.
The computer for the alarm is under a kick plate near the driver's door next to the driver's seat on the left side. Once it warms up the alarm; it will shut off the alarm and you can start the motor.

ive had this happen changing batteries on grand cherokees-close the doors and with the door key lock and unlock the drivers side door with only the key.then try seeing if the security lite goes out and start the car. sometimes this doesnt work on dr. side and you have to do the same on passenger door. this is for the factory alarm.

There is a security feature that will allow to go for a short distance but will stop. It is basically the same as the alarm, when you lock your doors, and then shut the door as you exit, there is a red security light that will blink in the dash. If you manually unlock and open any other door besides the driver door, the alarm will go off. To disable the alarm you have to cycle the key in the driver door. The same goes for the security feature. Cycling the key in the driver door lock manually, should disable the security feature until the doors are locked again. There may be a problem with the remote if you use it instead of you key to unlock your door.

Same here. What I do is lock all doors using the button on the driver's door before opening the door, then open the driver's door and lock it manually. That seems to keep it disarmed. I believe it has to be the driver's door for this to work, but I don't know for sure.

When my alarm goes off, it usually happens when someone sticks their hand in the window to unlock the door. In order to turn off the alarm I close whichever door the person opened back, and unlock the door from the driver's side door. This usually turns the alarm off.
