What is the fuse called that controls the key in ignition sound

Shut off the chime ? You want to shut off the chimes or they don't work ??>?? Which chime ?
Audible Warnings Circuit Description
Safety Belt Warning Chime
Voltage is supplied to the body control module (BCM) through the following components when the ignition switch is in the START or RUN position:
• The GAUGES fuse 4
• CKT 39 (PNK)
When you first turn the ignition switch to the START or RUN position, a class 2 signal from the BCM is sent to the instrument cluster logic turning ON the fasten seat belt indicator. The indicator comes on steady for 20 seconds and then flashes for another 55 seconds if the drivers safety belt remains unbuckled, or goes out when the drivers safety is buckled. When the drivers safety belt is buckled, ground is no longer applied to the BCM through CKT 238 (BLK/WHT) from the seat belt switch causing the lamp and chime to go out. The chime will only sound for about the first 5 seconds of the ignition on cycle.
Key-In Warning Chime
Voltage is supplied at all times to the BCM through the following components:
• The Underhood Fuse Block TBC fuse
• CKT 1140 (ORN)
The chime sounds if all of the following conditions exist:
• The key is in the ignition switch.
• The ignition switch is in one of the following positions:
- ACC
- LOCK
- OFF
• The LH front door is open.
When the ignition key is in the ignition switch and the LH front door is open, the ignition key alarm switch closes. The LH door jamb switch also closes. When both of the switches close, the Body Control Module (BCM) senses ground through the following components:
• CKT 126 (TAN)
• The LH Door Jamb Switch
• CKT 1050 (BLK)
• SP203
• C203 cavity F12
• G203
The chime will sound for as long as the door is open and the key is in the ignition switch.
Lamps-On Warning Chime
Voltage is supplied through the ILLUM Fuse 12 to the BCM through CKT 1220 (GRY) when the following conditions exist:
• The headlamp switch is in the PARK or Head position
• The ignition switch is not in the RUN or START position
• The IP dimmer switch is not at the dimmest setting.
With the IP dimmer switch at the dimmest setting, the current to the BCM may be too weak to be sensed by the module. When the ignition switch is turned to the RUN or START position, voltage is supplied from the GAUGES Fuse 4 to the body control module through CKT 39 (PNK). When the ILLUM and GAUGES Fuse voltages are sensed at the same time, the alarm is not sounded. The GAUGES Fuse 4 loses voltage when the ignition switch is in one of the following positions:
• LOCK
• OFF
• ACC
I'am assuming the chime stays on all the time .

The warning chime sounds if the parking lamps (13200) or the headlamps (13008) are left on after the key has been removed from the ignition switch lock cylinder and either front door (20124) is opened. There is a chime module that controls this .
The safety belt warning chime (10D840) (also called the central processing unit or CPU) is an audible warning system and timing circuit. The system components include:

• Timing circuit safety belt switch.
• Dome lamp switches.
• Safety belt warning indicator switch which is an integral part of the front safety belt buckle end (61203).
• Ignition switch (11572).
• Headlamp switch.

The warning chime sounds and the safety belt warning indicator illuminates when the ignition switch is placed in the ON position and the LH front safety belt is not buckled.
Key In Ignition Warning
The warning sounds if the key is left in the ignition switch lock cylinder when either door is opened and the ignition switch is in the LOCK or OFF position.
Don't any of chimes work ?

• The Headlamp on Reminder Chime Is Inoperative/Does Not Operate Properly

• Circuits.
• Fuse junction panel.
• Warning chime module.

• GO to Pinpoint Test D .

Let me know ,mite work this out !
Don't

Sounds like weak connection somewhere,I would start by one at a time,clean by scraping the prongs of each fuse. If this does not resolve your issue go by one of the parts houses that provide free electrical and charging system checks

Electronic Park Lock (EPL)/Ignition Lock Cylinder Control Actuator: If the vehicle is equipped with automatic transmission and a floor mounted console gear shift, it has an ignition lock cylinder control actuator system in the steering column. The ignition lock cylinder control actuator purpose is to prevent the ignition key from being turned to the OFF position when the transmission is in any position other than PARK and the vehicle may still be moving. The column ignition lock system consists of an ignition lock cylinder control actuator, and a park position switch that is located in the automatic transmission shift lock control switch. The ignition lock cylinder control actuator contains a pin that is spring loaded to mechanically prevent the ignition key cylinder from being turned to the lock position when the vehicle transmission is not in the PARK position. If vehicle power is lost, and/or the transmission is not in the PARK position the operator will not be able to turn the ignition key to the lock position and will not be able to remove the ignition key from the column.

Does your impala have floor shifter ?

should be a fuse in the fuse panel for door alarm simply pull the fuse out for the easiest fix

First of all NEVER replace a fuse with one of a bigger size. By doing this you have probably fried some wiring in the ignition system. There is a major issue with your electrical system. You shold call a tow truck as it sounds like you don't know much about electricity, not being mean, just honest.

Not to worry a fuse blew, delta 88 have fuseable links that are equipt in certain area there are some at the starter they blow open. There are some at the positive battery connection that controls dash and ignition switch, so the one we are going after is the ignition switch controls so when you turn the key on inside light goes on and door jam light goes on and better yet the key in ignition goes on. lets hunt that fuse down. First a fuseable link is a wire that allows heavy current to flow through it if it exceed the rated amperage it blows open 2 ways it opens youll see it seperated or you put your hand on it andtug it and it stretches because the wire seperated internally.So go to the positive of the battery are there link there do you see opens how about tugging anything stretched out. okay lets goe to the starter are they open or stretched if you find any open or stretch you need to replace it. now do you have a fuse box the one in the engine compartment is called a battery junction box look for fuses that went open.If everything is intact and looks good now lets go the the ignition area take a peek along the steering column. and turn the key see the rod that moves. as you turn the key that called a strut iginition rod. follow it it will lead to a juction that is called electrical ignition switch feel and move some of those with the key on and if you get power on(You will have to have the key on to do this) there you will find the problem. let me know

mcdevito75 here, The key completes a warning circut in the off position of the ignition switch, this buzzing sound is a relay usually in the fuse box, find the fuse box, leave the key in the switch, listen and locate the buzzing sound and remove the relay from the fuse box, this relay may also be alone just under and around the steering column.

The OE alarm is part of the ETACS
To disable it:
1) Sound the alarm
2) Put the key in the ignition and turn to start
3) Hold there until the alarm turns off
You should now be able to start the vehicle. The alarm will remain dis-armed until armed through RKE

the climate control panel power goes through the ignition switch. So, it sounds like you could have a switch issue.
Do other things work witht he key off as well? Like the wipers, radio

Do you have electronic or manual heater/a/c

If fuse #21, 50 amp, and its yellow 37 wire to the ignition switch is somehow hot with the key off, it could be the problem.
Pull that fuse in the power box in the engine compartment & see if it shuts off.
