Expert Answer

Aftermarket alarms have a reset button that's typically found on the left side knee board or underneath the hood by the fuse box.

In most cars, you have to get under the seat and unplug the plug underneath it to disable the seatbelt alarm.

Question

My 2001Tahoe alarm sounds whenever I unlock and open the door. I don't have a remote door lock. What can I do to stop the alarm from triggering?

Community Answer

When I had this problem, I was told to insert the key into the door, turn it quickly and to the left three times, and then to the right once. This will turn off the alarm. If you're quick you can also get into the vehicle and turn on the engine to stop the alarm from sounding. Unfortunately you'll have to do either option each time you unlock your car.

Question

What should I do if the battery is disconnected the remote will no longer work due to lost memory?

Community Answer

Check your remote's instructions on replacing a battery. Usually, the remote will maintain its setting for 10 to 20 seconds after you remove the battery. You have to replace the battery quickly, so make sure when you take it out, you know which side to put the new one in.

Question

How do I turn off the vehicle theft alarm light on a 2010 Dodge Grand Caravan?

Community Answer

The theft alarm light on the dash is there to tell you that the alarm system is working, not that it is activated. There is no need to turn it off.

Question

How do I retrieve the reset button on my 1997 Toyota Paseo that fell behind the panel?

Community Answer

You need to take the panel out to get the button. Or you can try and reset the alarms manually by cutting wires, or motherboards, or whatever you have that makes the alarm go.

Question

My 2011 Dodge Ram pickup alarm has started to go off randomly. I replaced the batteries in the key fobs as dealer recommended, but it didn't help. What else can I do?

Community Answer

This may be a problem with the alarm sensor. I had the same problem with my 2006 Bentley Continental. I replaced the sensor and it worked perfectly after that. If that does not work, consider a new alarm system.

Question

I have a 2013 Nissan Sentra and when I set my alarm, it doesn't beep but the light flashes. What causes that?

Community Answer

It's been deactivated. On the fob, hold the lock and unlock buttons for a few seconds to reset it.

Question

My car key doesn't have a battery, so it doesn't work at all. How can I turn off my car alarm without turning on the car?

Community Answer

If you have the key with just a dead battery, you can get it replaced for less than $15. If you have the key but no remote, check with the dealership or even online to replace it. They are programmable, so that usually takes a dealership or finding the right information to try to do it yourself.
