Question about 2006 Chevrolet Cobalt

5 Answers

How do I disable the alarm system for my 2006 Chevrolet Cobalt? Every time I unlock the doors and open them, a short honk beeps in 1 second intervals, and then after ten seconds proceeds to the full honking alarm. This happens both when I unlock the car using the turn-key lock and the inside electric unlock button. Rather than get into technical wiring or fixes, I would much rather simply disable the alarm.

That is the normal security set up for just about all vehicles for when you open your door with a key same with entering a house with a security system open door you have a few seconds to put in code --as for vehicles your code is by putting your key in ignition and either turn it on or start --your vehicle should be key fob ready ebay-amazon or online they cost only a few dollars and the program is simle-----and you cant dissconnect the alarm system doing so will cause no start and component damage

No fuse or relay will fix it. The dealer mechanic can go into the computer and disable it for $100. I'm going now to cut the horn wires. Key fobs are $80 each.

If you lock your doors with the remote, you have to use the remote to unlock them or it set off the alarm. I don't know why the manufacturers designed it that way(kind of stupid)but it's programmed into the on board computer. You can't disable the alarm without creating a worse problem somewhere else.

If I lock my 2006 Chevy Cobalt, the security system will randomly lock and unlock the doors accompanied with the horn honking


I think you have a BCM - body control module problem ! The BCM controls the automatic door locks .
Automatic Door Lock Operation
This BCM controlled feature can be personalized to driver preference. Refer to Power Door Systems Connector End Views Personalization Description and Operation in Personalization.
The BCM will automatically lock the vehicle doors if the following conditions exist:
?€¢
All vehicles doors are closed.


?€¢
The ignition is in the ON position.


?€¢
The vehicle is shifted out of PARK.

The BCM will then unlock the doors when the ignition is placed in the OFF position. Do the exterior lights flash as well as the horn sounding ?
Body Control Module (BCM)
The
Content Theft Deterrent
system is an internal function of the Body Control Module (BCM) which utilizes class 2 serial data and various switch input information to perform CTD functions. When the BCM detects an unauthorized entry, it activates the horns and exterior lamps.
When the BCM detects an unauthorized entry, the BCM enters the alarm mode. The BCM activates the horns and exterior lamps for 2 minutes. This is followed by a 3 minute time-out with the horn no longer active. If no new intrusions are detected after the time-out, the horn is not active. The system must be disarmed or the intrusion condition removed after the time-out for the system to exit alarm mode.

How do I get my alarm system to chirp instead of beep when it goes off or when I lock my doors with the remote entry key fob?


Check to see if your vehicle honks when you press the "lock" button on your key fob. Press the "lock" button multiple times in a row. Many devices won't beep unless you double-tap the button after locking. If the horn doesn't honk, but the lights flash, your chirp feature is probably disabled.

Use your keyless fob and ignition key to enable the audible chirp. The process varies considerably on different makes and models. You must usually consult your owner's manual, a dealership or the alarm manufacturer for the correct process.

I have a 2005 cobalt every time I open the doors the alarm goes off I replaced the battery in keyless entry but they do not work can anyone help?


You may have accidentally broke the controller. They are fragile. The newer cars like yours automatically set the alarm when the doors are locked from keychain remote, or locking manually. New remote, $50-100.

Why would a 2005 passat honk when being started?


If it honks once, it is because the alarm was reset. The alarm can be reset by not starting the car within the time allowed (you have about one minute from unlocking the car to starting the car or it re-enables the alarm). It typically does a short beep to indicate that the alarm is re-enabled. If you hear that mini-beep, just press the Unlock button on your remote. Your car will not honk when starting.

My guess is that the designers thought... if the driver unlocks the car and opens the door but doesn't start the car and instead leaves the car unlocked... that it will notify the driver that someone is trying to steal the car. Unlikely. It just makes me frustrated when I hear it.

DIC Vehicle Personalization Your vehicle has personalization capabilities that allow you to program certain features to a preferred setting. All of the features listed may not be available on your vehicle. Only the features available will be displayed on your DIC. The default settings for the features were set when your vehicle left the factory, but may have been changed from their default state since then.

I have a 98 Nissan altima gxe and my alarm won't honk when I lock the car but the lights go off when I lock it and Wen I take the alarm off no honk or lights go off Wat can I do


holdboth the lock and unlosk buttons on your remote simultaneously for about five seconds until the lights flash and horn chirps.that should do it.if not i believe these models used a separate horn for security system.possibly fuse for this horn is bad or the horn itself is bad.to see if this horn works lower drivers window.stand outside vehicle and lock doors with remote.wait about a minute and reach in window and MANUALLY unlock and open door(do not use power door lock button)this should cause the system to activate...horn should beep and headlamps should flash.if horn beeps try my first suggestion.if it doesnt beep and just the head lamps flash check fuses and horn for security system.

I bought a new Keyless remote for a 2007 Forester from a Subaru Dealer to replace an original one that went bad after 2 years. I have followed the directions in the owner's manual to program it, but can't...


IMPREZA: 2005, 2006, 2007 and
FORESTER: 2005, 2006, 2007, 2008
Check for Immobilizer key on Forester XT models only.
information is always subject to change and correction imp05keylessremote1.jpg
new remote for 2005 Imprezas.
This is not the same remote as the 05 Legacy/Outback remote which also has truck/gate release on the front and a red panic button on the back.
Lock: press Lock button for 2 seconds or so to lock car, and arm optional security system. The car with chirp once and turn signals flash for locked, 5 short chirps and signal flashes if any door is not fully closed. The dome light goes on for 15 seconds and ignition key ring (if present) will light for 30 seconds when unlocked.
Unlock: press unlock one time for driver's door, press again within 5 seconds to unlock all doors inkling rear gate (wagon). The system does not open the trunk.
Panic mode: press and hold lock button for approx. 3-4 seconds to activate Panic mode. I panic model the horn honks and turn signals flash until either the lock or unlock button is pushed again.
Finder mode: Press lock button 3 times within 5 seconds to activate Vehicle Finder mode. The horn will honk once and the turn signals will flash 3 times
Distance: works within approx. 30 feet depending on battery strength, nearby concrete walls and etc.
Audible Chirp On-Off: the system will chirp when locked or unlocked. To turn OFF the chirps, unlock the door and then push both lock and unlock buttons at the exact same time for 2+ seconds. There will be 2 chirps indicating the the audible is off. To turn the chirp back on, repeat the process and the system will chirp one time when it is back on.
Battery: as the battery ages it will only work as you get closer to the car. When a battery is replaced, the transmitter must be re-synchronized with the Keyless control unit. To synchronize, press the lock or unlock button 6 times.
Programming: 4 codes may be programmed.
Sit in driver's seat and unlock all doors. Open and close the driver's door
Turn the ignition key from LOCK to ON position 10 times within 15 seconds. Be sure to stop at both lock and on. The horn will HONK once to indicate transmitter programming mode is activated. Leave key in LOCK position and don't remove it from ignition.
You now have 45 seconds to complete the programming as below.
Open and close driver's door again.
Push either lock or unlock button on the remote you want to program. The horn will honk 2 times when successful.
To continue and program other remotes at the same time: open and close the driver's door and push lock or unlock on the remote. The driver's door must be opened and closed between each remote you want to program.
Done programming? remove the key from the ignition and the horn will honk 3 times.
DELETE old codes? Reprogram 4 times, it will overwrite old codes.
Alarm Security System: optional on all models. When locked there is one chirp (can be turned off, see above), the turn signals will flash and the red 'security' light will start to flash once every 2 seconds except for STi which flashes twice every 2 seconds.
There will be 5 chirps if a door, hood, and trunk or gate is not fully closed
You can also arm the system by using the power lock button on the driver or passenger door as you get out of the car and then closing the door behind you.
Disarm the system: push unlock for 2 seconds
Lost remote, alarm activated? When you can't use a remote to turn off the system: open the door with a key or try to start the car and the horn will start to honk. Turn the key on-off 3 times within 5 seconds and the alarm will go off and you can start the car. It's simple!
VALET mode: To set valet mode or just to disable the security alarm system: 1. unlock all doors 2. physically open the driver's door 3. hold the UNLOCK button on remote for 2+ seconds. The red 'security' light will then flash 2 times a second until the car is turned on.
System has been Tripped (except for STi): if you unlock the door with the remote and it chirps the signal light flash 4 times, the system has been triggered;
Identification mode: To find out what happened and why the system was triggered:
Open and drivers door, leave it open. Turn ignition key from LOCK to ON 2 times and then leave in LOCK position.
Tripped code: 1 security light flash: a door has been opened, 3 flashes when the impact sensor was triggered, 4 flashes when the ignition was messed with or battery disconnected
