I've got door chimes when I open my door, with no key in the ignition, I get sporadic dash lights, and if I get that far, and turn the key to on, I can hear the pump, and a click, then circuits die. They also die when I try to turn on the headlights. The circuits won't come on again until I dis and reconnect the battery. I've got power going from the battery all the way through the relay, plenty of battery charge. Wondering if this could be a problem with the ignition switch, or just faulty wiring.

Replace ign switch

Key in ignition or the spring in the ignition cylinder that activates chime for "key in ignition and door open" is stuck. Fast chime is lights and slow chime is key in ignition while door open

How about a year, make, model? They're all wired differently

How do you program the key to a 2001 Ford Focus? 1. Turn the ignition from off to run four times in six seconds. 2. Turn the ignition to off. The car will chime to confirm that you've done everything correctly so far. 3. Press any key on the first remote you're programming. Perform this within 20 seconds of step 2. The car will chime to confirm programming. 4. Repeat step 3 with each additional remote.
great diagnostic tools

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.

you may have a bad switch which is located on the latch asm

there is a small switch in the steering colum the the cylinder switches on and off

Audible Warnings
The body control module (BCM) will provide an audible warning for various events relating to the vehicle. The functions that provide an audible warning are the key in ignition, the lights on, the occupant restraint (seat belt) and the park brake.
Key in the Ignition Audible Chime
The BCM will provide an audible chime if the key is left in the ignition in either OFF or the accessory position with the driver's door open. The chime rate for this is 150 chimes per minute. The key in the ignition chime has a higher priority than the lights on chime.
Lights on Audible Chime
The BCM will provide an audible chime if the park lights are on and the driver's door is open. In addition, 1 or 2 other conditions exist. The key is out of the ignition, or the key is in the ignition in the OFF position, and has not been turned. The BCM will chime at a rate of 200 chimes per minute until the conditions are removed.
Occupant Restraint Audible Chime
The BCM will provide an audible chime based on the class II message received from the SDM if the driver's seat belt is not buckled when the ignition is turned to run or crank. The chime rate for this feature is 50 chimes per minute.
Park Brake Audible Chime
The BCM will provide an audible chime for park brake when the park brake is applied and the vehicle speed is higher that 3 mph. The chime rate for this feature is 200 chimes per minute.

You can't disconnect anything . The problem has to be fixed .

Telltale Chimes
The body control module (BCM) will provide 4 chimes for each telltale activation per ignition cycle, at a rate of 150 or 200 chimes per minute. The chimes are limited to 1 chime event per telltale for each ignition cycle. The power up telltale function will not activate the telltale chime function. If the telltale becomes active during a cycle then the chime will sound.
The following telltales will activate the chime function:
• Low Washer Fluid
• Change Oil Soon Indicator
• Brake Fluid Low
• Oil Pressure Low
• Coolant Temperature Hot
• Low Coolant Level
• Low Fuel Level
• Antilock Brake System
• Volts Light (Generator)
• Supplemental Inflatable Restraint System (Air Bag)
• Trunk or Hatch Ajar

Having the vehicle checked for DTC'S - diagnostic trouble code's in the BCM would be the first step in the diagnostic procedure .
DTC B2965
When the ignition key is seated in the ignition switch, the key-in-ignition switch contacts the close, grounding circuit 80. The body control module (BCM) monitors the state of the key-in-ignition switch, the state of the ignition switch (OFF, ACC, or RUN) and the driver's door to control the key-in-ignition chime.

Sometimes the ignition key does not "deactivate" when removing the key...try wiggling the washer behind where the key goes...sometimes this sticks...:)

This chime is also the same chime used for the doors. To remove this you will also be losing the ignition chime when the keys are in the ignition or when the doors open.
It can be removed simply by unplugging it. Just open the door with the keys in the ignition, look under the dash on the driver or passenger side. using you good hearing locate the chime and simply disconnect the plug from the back.
