Key won't work alarm went off a day before

Keys wont unlock or lock doors and the ignition doesn't turn. I have tried all 3 of my keys, one is the wireless key, which says doesn't recognize. The alarm went off the day before with car unlocked and key inside. Couldn't get it to stop by unlocking the doors or putting the key in the ignition.

Alarm won't turn off

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

I started my car on day and the next day I unlocked the door and the alarm started and would not stop. My buddy diconnected the horn and the car won't start...help

i believe if you put key in ignition turn it forward and back off twice it should reset the anti theft to start it. or unlock pass door with key and that might reset it. also try the same with back pass door if the other didnt work. hope this helps.

HELP please!! My daughter has a 96 sebring convertible and today she put her key in the door to unlock it and the alarm started going off. It wont stop, have disconnected the positive and negative battery...

Just a quick note once you hook the battery back up try locking it and unlocking it from the drivers door, if that fails you might try the passenger door. I know on some chrysler products you have to lock and lock again to arm and unlock to disarm. I hope this helps.
Thanks,
Joey
