Try two different things for me.
Car light warning alarm not working.
Close the vehicle s hood and start your car to check that the computer has reset and that the warning lights have disappeared.
It got tired after 4 years of monitoring your car s doors and windows and occasionally triggering the alarm or it got bored and called it quits because nothing exciting ever happens with your car.
Get in your car close the door and cycle the key turn the key on but don t crank the engine then turn it off again.
Use key to lock and unlock.
You may also try turning the car on to reset the alarm.
When you lock your car using a remote you may see an led flashing but there is no noise.
When the vehicle notices that the key has been inserted into the lock the alarm may shut off.
Ok somehow when i went out to my car and try to hook the alarm back up the 12v wire seems to be missing i can t find it.
I think my bro did something to it when i asked him where it was at he said he forgot.
There are 2 possible causes.
Lock it like you normally would which i would assume is your keyfob.
A glowing led indicates that the car alarm system is on only it does not produce any sound.
Alarm light won t come on alarm not working properly car audio car forums.
If you still want an alarm system you should replace the old one.
Reconnect the negative battery cable to the terminal and tighten the nut that holds it in place.
Get out of your car.
Sometimes an alarm will deactivate when you try manually locking and unlocking the car.
With the key still in the ignition open the door.
