Question about 1999 GMC Sierra

Open Question

I want to disable my security alarm system. HELP!

The keyless entry went out and the security alarm system is on alert and I can't get it to shut off. First of all, I pulled the fuse to the horn and stopped the NOISE but alarm is still on. I took the battery cable off in hopes of resetting the system...didn't work. Yes, for $100+ dollars I can buy a new keyless entry. Tired of nuisance and want to disable the alarm system. Where do I start? How can I get a free electrical/alarm diagram for my 99 GMC pick up?

SOURCE: 99 gmc jimmy sle keyless remote and security issue

Hi: From my experience the security issue is easily solved because hitting the factory key FOB lock button is the only way to activate it, hitting door lock button will not activate it. When installing a remote starter no wires are cut usually, just spliced into which means... make sure that where wires were spliced they are taped. If you have the original factory key FOB use a quarter and pop apart, replace the battery, key FOB should have retained its factory setting if your lucky, if doesn't work go to internet search and find programming procedure. Hope this helps... please rate suggestion...ty

SOURCE: 2007 gmc yukon denali wont unlock w/ keyfob

Check the buttons.. I have an 06 Grand Prix with the Remote starter on the top and it seems that the conductor on the buttons worn out.. Take the keyfob apart, pull the rubber buttons off the chip, lick your finger and touch the place where the unlock (right side of the fob) would be. That should unlock your doors. I just did it with mine. I would just buy another fob on ebay and change the buttons out.. Hope this works

SOURCE: My head lights were flashing

do you have a remote starter also? If so then that is the culprit. If this is an after market alarm then time for a new one. if not then take it to the dealer to reset.

How do you turn off an alarm for a 2005 Saturn Ion


Disarming an Armed System/Silencing an Alarm
If system arming has been requested by the keyless entry transmitter, it must be disarmed.
Important: Using the power door unlock switch or manually unlocking the doors does not disable the CTD armed mode. Also, disconnecting the battery or pulling fuses does not disable the armed mode, since the BCM stores the CTD mode status in memory.
?€¢
To disarm the CTD system in arm pending mode, SECURITY indicator flashing and doors open, perform 1 of the following:


-
Press the UNLOCK button on the keyless entry transmitter.


-
Insert a valid key into the ignition and start the vehicle.

How do I disable the security alarm on my 1999 Subaru Legacy? I do not have a keyless entry


If your just dealing with the alarm/horn going off all the time, you can try disarming it when it goes off by putting the key in the ignition and turning it on and of three times ending with the last turn in the on position. This will stop the alarm from sounding.

Battery went dead on car, car security system is in safe mode and want let car start, when you unlock the car alarm sounds and want do anything else, Battery has been replaced, can i reset the alarm if so...


Hello,

The new battery should have reactivated the alarm? If this is a keyless entry, than your original code should work?

If it doesn't than you need to call the dealer, or seervice provider for your alarm system there has to be a reset code, or a new one has to be provided?

I would try your normal code first! If it works, your good, if not, your going to be on the phone! No body but the place you purchased your vehicle from or the Alarm system provider can give you that answer!

Kind Regards!

2004 Hyundai Elantra won't start, emergency flashers keep blinking, can't shut off, lights dim, can't jump start, clicking from under dash from relays. What could it be?


The 'Keyless Entry & Burglar Alarm System" is activated. You must 'Disarm' the system using the Keyless Entry Remove (Key Fob) to "Reset" the system. The reason the engine won't start is due to the burglar alarm - it has a "Starter Kill" circuit which is activated when the alarm is activated. The alarm must be DEactivated to DEactivate the 'Starter Kill' circuit.
Another way to start the engine is to get in the car, put the key in the ignition and turn it to 'ON" and wait 3 to 5 minutes until the emergency flashers stop/turn off. Afterward, you should be able to start the engine. NOTE: This does NOT reset the burglar alarm. It will go off again when you enter the vehicle without using the remote/key fob.

New battery -alarm sounds- have to disconnect the battery-


The sounding alarm maybe a security system installed by in the truck. Disconnecting the battery will only temporarily solve your problem, but will resume once you reconnect the battery for electrical power.

You must find the keychain/remote of the security system and disable it. If you are unable to locate this, you can have it disconnected by a qualified automotive electrician.

Word of caution though, if you are using the keyless entry system with the security system, this will be disabled until you install a receiver with such function.

Hope this helps.

Unfortunately, the keyless entry remotes and OE systems usually require a dealership to service them. Sounds to me like they need to re-set the alarm

Did the 96 toyota camry come with an alarm if so how do I disable


actually your car has to have keyless entry, it's part of the alarm system that is given you problems. I had a similar issue with my 87 camery, sounds like they still haven't fixed it in 96.. anyway the fix was for me to take the VIN number over to my local dealer dish out about 35 bucks and get the remote control unit for the alarm system. That also gives you keyless entry :).. So for 35 bucks it was well worth the investment.

In order to disable the alarm there should be a red or black button under the streering colum to left side. You must put the ignition in the run position, and then hold this button for thirty seconds it should disable the alrm until you repeat that procedure.

After market alarm went off and could not be reset. disconnected the system that was tapped into the ignition wires. still no power to anything including lights power locks windows ect. black box mounted...


what year is the Mustang? It does sound like the factory keyless entry module and the clicking is a relay inside of it. In order to disable the clicking, you would need the factory keyless entry remote or the aftermarket alarm system would have to be correctly wired to the vehicle's alarm disarm wire. A professional stereo shop would be able to handle this for you.
