Resetting Your Car Alarm Remote

Resetting your car alarm can be a somewhat involved process but it doesn’t have to be as difficult as you may think. By taking care of it as soon as possible you can not only have your alarm system running properly but save yourself from the embarrassment of a malfunctioning alarm in the presence of your neighbors. But more importantly, fixing it will safeguard you from the threat of theft.

Remember, that cars are made of electronic materials, and electronic materials malfunction every now and then. Here, we will be examining the easiest routes to resetting your car alarm remote with as little difficulty as possible. Pay attention to the following step-by-step processes, and even look up additional visuals if required for an added layer of self education.

Keep in mind that you want to steer clear of any repair work that you feel is over your head, as this can not only put yourself in danger, but your vehicle can take a toll as well. Although the following how to guide is applicable primarily to factory alarms, it can also be useful for resetting aftermarket alarm remotes as well. Now, the following descriptions will include five different routes one may take to resetting their car alarm remote. Have a look.

Route 1

Keep in mind that there is a possibility that your alarm remote is no longer transmitting signals from itself to the alarm system. Sometimes this results in the alarm randomly going off without your consent. This first method will address that issue.
The first thing you want to do is take a look at your car’s owner manual.

Older cars and newer cars alike should have step by step instructions within the manual to reset the alarm remote. Although this method will differ depending on the make, year, and model of your car, it usually entails removing the fob battery and installing a fresh battery. You also have the option of utilizing what is called a code reader.

Some newer vehicles in particular require the use of one in order to reset the alarm remote. Although many owner manuals provide step-by-step instructions on resetting alarm remotes, the help of a mechanic can still go a long way.

Route 2

Route two involves a less complex procedure that is not so time-consuming as it is to carefully examine an owner’s manual. See whether or not the alarm deactivate on its own after unlocking and then subsequently locking the car in a manual manner. Oftentimes, this deactivates the alarm system altogether.

Many cars will automatically shut off the alarm system as soon as key insertion is recognizable. Sometimes, simply turning the car on can be enough. If this does the trick, then you have successfully reset your alarm without having to go into any in-depth procedures. Another procedure worth trying is to turn your key from the lock to unlock position two or three separate times.

Sometimes, cars can recognize this as a code to reset or disable the alarm.Positioning the key in the unlock manner for several seconds could also do the trick, and is worth trying if none of the other methods work.

Route 3

If none of the above methods did the trick, your next option is to reset the battery. Since, of course, the alarm uses the battery as its power source, you may need to disconnect the battery to get to the heart of the issue.  Doing so, however, can pose something of a threat and therefore caution should be used.

When locating your battery, the first thing you always do is open the hood of your car. You will then detach the negative wire, and with the help of a wrench take off the nut attached to the negative terminal itself. You are then free to separate the wire and the battery. Next, you will wait a minute or two at the most. Now, try reattaching the negative wire to the battery.

By now, your system should be reset, and you can test whether or not it affected the alarm. Remember that whenever you disconnect the batteries your radio presets are essentially thrown out the window, so be sure to jot down some of your go-to stations.

Route 4

If resetting the battery didn’t work, you will want to give replacing your car’s fuse a shot. As a side note to this method, also try replacing your individual car alarm fuse.

Fuse boxes can usually be found to the left of and slightly lower than the steering wheel. You will want to take off the fuse box cover and locate the proper fuse. Now, with a bit of a yank, detach the correct car alarm fuse. If you’re having trouble finding the proper fuse, definitely refer back to the manual. Now replace the fuse.

Route 5

You may also want to give disabling the alarm a shot, if none of the above methods worked for you. Disabling the alarm altogether is usually what is necessary if the alarm is triggering on randomly. If you do disable the alarm, you’ll want to enable it properly as soon as possible so that when you do drive, you have this important safety feature at your disposal.

Typically, disabling the alarm is a much more involved process that requires the consultation or hands-on experience of a mechanic. Depending on your vehicle, disabling the alarm may in fact simultaneously disable your vehicle’s ability to start. So keep this in mind as you embark on this trial.

You can figure out how to disconnect the proper wires by taking a look at the owner’s manual. Triple make sure that the battery is disconnected before you tamper with any wires. Now, identify the siren alarm unit itself. You will then want to disconnect the corresponding wires. See whether or not the alarm is in a position to where it must be fixed in a permanent manner.


Those who have faced issues with their car alarm system, know how trivial it may feel. But rather than downplaying the issue at hand, it is better that you get to the heart of it, that way both you and your passengers are as safe as possible while driving in your car. Hopefully, one of the above methods works for you, otherwise you may need to bring in the assistance of a certified mechanic.
