Hi!!
I believe your alarm is in the PASSIVE MODE, here is how it works.

PASSIVE MODE Setting (Arming) Anti-Theft System The system will automatically set 30 seconds after following methods are performed: Remove ignition key from ignition switch. Exit vehicle, and close all doors. After performing this, anti-theft indicator on left side of instrument panel will light continuously for about 30 seconds. After 30 seconds, anti-theft indicator will blink once per second. When system is set, doors cannot be locked or unlocked using door lock control switch.
CANCELING THE ALARM AND REPROGRAMING MAY SOLVE YOUR PROBLEM.
Canceling Anti-Theft System Setting (No Alarm) When system is set (armed), but alarm is not sounding, use one of following methods to cancel system setting:

• Unlock left or right front door using key.
• Unlock all doors using remote keyless entry system.
• Insert key in ignition switch and turn to ON position (this is operative only when anti-theft system has not been triggered).

If these tips did not work or your controls are not working correctly you may need to schedule service.

First lid must be down before washer start spinning. Remove any obstructions in drain hose and or straighten drain hose to remove kinks. Lid or other object hit timer knob and turned the washer off - Make sure the Timer knob is pulled out.
If the lid was opened with too much force when adding clothes, it may have hit the timer knob, pushing the knob in.
If a laundry basket or other object hit the Timer knob, the Timer knob may have been pushed in shutting the washer off.
Washer lid is not locked (Not on All Washers) - The lid must be closed and locked for the washer to operate. Once the lid is closed, make sure the desired cycle is still selected and then press the Start button and listen for the lid to lock.
Make sure there are no loose metal objects such as coins and paper clips in the lid opening area. Metal objects can prevent magnetic switches from reacting correctly when the lid is closed.
If the washer has not drained, it will not go into spin.
Use a flashlight to inspect the holes in tub for foreign objects like screws, nails, bra wires, etc. and remove if present.

Sounds like you bent the door where the lock is. You might have to replace the door.
