NO.The battery is charged by alternator while its running.In otter case battery remains charged.If car not driven for few days the battery loses it charge. But the alarm code is set in the cars ecu/pcm(the cars computer).If the code is required then it has to be inserted.If the code is not inserted then the computer will not let the car to start till the code inserted.
To reset alarm or disable alarm if there is no code,the car has to be taken to dealer. Thanks. Keep updated for any more query. You can rate this solution and show your appreciation.

How do I disable alarm 1993 Isuzu trooper? It will not start. Engine just clicks. It wouldn't even start when tried to jump start it.


I don't know how to disable the alarm for your Trooper. With most cars however, if you open the drivers side door with the key, and insert and turn the key to try to turn it on (even though it won't start) that should disable the alarm.

It sounds like your battery may be completely dead and needs to be replaced. ORielly's auto store will check /charge your battery for free. You'll just have to unhook the battery and get a friend to take you.

Can the car alarm kill your battery but you can start the car but after you turn it off battey died again


sure, if you let the alarm drain the battery, this can destroy any stock battery.
The car batteries are not like golf carts and are not deep discharge rated. (so can be damaged)
so charge the battery, if it wont hold a charge, it is bad.
if it discharges silently, and darkly parked , that is phantom discharge
if is discharges , driving that is a engine charge system failure.
parked over night discharging is phantom discharging.
if the alarm goes off and stays in alarm , then dont use, it.
if the battery is happy with the alarm defeated then the Alarm is bad.

The battery measure 12.6vdc charged,(rested) "voltmeter"
and running measures, 13.3 to 15vdc at idle.

this one tool can solve this problem

Battery drain overnight on pontiac 1994sunbird


The alarm light will not kill the battery. Your diode in the alternator may be bad. This will slowly drain the battery. Replace the alternator. Or charge it up and go to auto parts store and have them test the battery and alternator and starter.

I have a 92 toyota celica gts with a code alarm installed after market. I went to start the car this morning and there is no power to my radio and the on dash digital clock. Obviously the car wont start...


It sounds like you could have a combination of problems. But, my first guess is a weak battery. The first step would be to charge the battery and then try to start it. If it starts, then take it to a auto shop where they can check the charging system. If your alternator is bad, then it will kill your battery. If your battery is bad, it won't hold any charge and overwork your alternator. If it still won't start after charging the battery, then check the fuses and replace any blown fuses. If it still won't start, have it towed to an ASE certified mechanic. I hope this helps.

The car soulds like the battery is low but when it starts the flashers come on.


Often an alarm system will register a low battery voltage and presume the vehicle's battery is being removed to prevent the alarm from going off. They will then begin flashing and or sounding the horn.
In your case, I would presume that the battery voltage is too low which may indicate either a failed battery, or a parasitic voltage drain.

First, get the vehicle started, and run the vehicle for a good twenty or so minutes to get some charge to the battery. If you don't want to waste fuel however doing this, then I suggest using any battery charger, as all we want to do is get some voltage back in the battery. If you are using a charger though, then charge on a lower voltage setting overnight.

Once you have the battery charged, run off any surface charge by turning the vehicle lights on for a minute, then turn them off again.

You need an ammeter for this next part:


Disconnect the battery positive terminal and connect the ammeter in series with the battery and positive lead.
DO NOT ATTEMPT TO START THE VEHICLE!

With all vehicle systems off, the key out, doors closed and alarm 'OFF', bonnet close switch depressed, or bonnet/hood clasp closed (need a screwdriver), take a reading from the ammeter.
After probably no more than twenty minutes, the ammeter should be reading 0.03 amps and not much more. Anything like 0.5 or 1 amp means you have a battery drain.
If this is the case, then start by disconnecting the alarm system. If the alarm system has it's own separate speaker/horn, then disconnect this first. Many of these horns have backup batteries, which only last three or four years before they fail, which causes them to constantly draw from the vehicle battery and then flatten it when parked.
Every time you disconnect an item or system, check that ammeter again to see if the amps have returned to normal. Pull fuses one by one, checking the ammeter each time for any change until you find the system which is causing a drain, then attend to that system.

If your amps are normal however and your battery is still loosing charge when parked for any short length of time, i.e. a few days or so, then your battery is at fault and requires replacement.

Just before changing your battery, do one last check, which is with the vehicle running. You need to reconnect any battery cables, and start the vehicle. Using the voltmeter once more, check the voltage across the terminals with the engine running. This is your charging voltage and it should go up to around 14 volts if revving the engine slightly. If still around 12 volts only, then you have a charging issue, which is probably the alternator.

Car won't start and arms alarm when I turn the ignition


Dead battery armed the security system. Remove the battery cable let the system reset. Charge the battery. Use the key to unlock the door instead of the keyless entry. This resets the alarm once the battery is charged.

My 1999 Bonneville will be sitting in a parking lot at work or at home and the alarm will just start going off. No one is around or close by with the keyless remote.\r\nWhat is causing this and can i...


A lot depends on exactly what is happening here. Are we talking about an aftermarket alarm system? If so, I personally would recommend removing the entire system - they are usually more trouble than they are worth! (Just my personal opinion based on 36 years of auto repair experience)

NOTE: The information below applies ONLY to problems with the FACTORY security system.

There is a possibility that the horns going off are not being caused by the alarm system at all. Some GM airbag modules/steering wheel switches have been known to short out intermittently and cause the horns to sound for no apparent reason. If the horn is staying on solid (BEEEEEEEEEEEEEEEEEPPPPP) then it is most likely NOT the alarm system. If it is beeping on and off at regular intervals (BEEP.....BEEP......BEEP...) and the headlamps are flashing, then the security system is probably at fault.

Low battery voltage or a shorted cell in a battery can "trick" your alarm system into "thinking" that someone is trying to steal your car. A THOROUGH battery and charging system check should be performed to find out if this could be the cause.

Also, your factory alarm is a PassKeyII system. This means that if there is a malfunction in the system, there is most likely one or more fault codes stored in the Body Control Module (BCM) that can lead you to the cause of the problem so you can get it fixed.

Please note that MOST generic code readers CANNOT access these type of codes.

Another way to work around this is to "disarm" the system. To do this, unlock the door using the key. Press the "unlock" button on the door. Then press the "unlock" button on the key fob (keyless remote). The system will disarm. When you leave your car, use the KEY, not the remote to lock the car. (If you use the remote, the system will be armed again.)
