There are plenty of reasons why you have to remove ADT windows and door sensors.

You may want to do it because you want to replace the old sensors, update the sensors, or you want to use a different type of ADT windows and door sensors.

No matter the reason, in this post we’re going to guide you through the step-by-step process for changing the ADT door sensors.

As you can see, you’ll find the answer to your problem in this post. But, before getting into the step-by-step process, let’s talk about what are the functions of ADT windows and door sensors and the types of ADT windows and door sensors?

We bet you’re excited to read, so let’s get to it.

Types of ADT windows and doors sensors.

In total, there are three types of ADT windows and door sensors. In this section, we’re going to tell you the names of functions of each type.

Alright, so let’s start with the Wireless ADT windows and door sensors.

Wireless ADT windows and door sensors.

As you can tell by the name, these sensors do not need wire to operate efficiently.

We know you don’t care much about whether they are wireless or not, instead you’re reading this section because you want to become familiar with the features. That’s fair, so let’s talk about the features.

The Wireless ADT windows and door sensors are placed at doors and windows to detect whether something fishy is going on.

If they sense a motion, that something is out of ordinary they’ll sound a loud alarm so the burglar will run away and the day will be saved.

This is good, isn’t it? Of course, but there is more. You can customize these motion sensors to your needs. You can select whether the alarm

goes off, doors and windows get locked, which doors and windows get locked, camera start recording, or all of them and more.

You’ve got to admit this is pretty slick. Installing these sensors, or all types of ADT windows and doors, sensors require a professional.

It means you’ll have to pay some amount for the installation ($99-$199), but you’ll save some time and energy.

Alright, next talk about the Wired ADT Windows and Doors sensors. As you might have probably guessed, there is not a lot to cover over here.

Therefore, we’ll tell you the difference in a few words and then move to the 3rd type.

The wired sensors cost more money but they are more efficient than the wireless system.

Recessed doors sensors

So you might be wondering what are recessed door sensors and how are they different from the other two? Well, hold your horses because this is exactly what we’re about to answer.

Function wise, recessed door sensors are about the same as the other two. But, they are more similar to the Wired ADT windows and doors sensors because they are pretty efficient.

Nonetheless, overall function wise there are no huge differences. So, what is it that makes them unique? That’s a pretty good question and we’re going to answer it in the next paragraph.

There are two aspects that make these sensors unique. 1) Aesthetics. 2) Durability.

First, let’s talk about aesthetics. These sensors are incredibly slim and beautiful. But, not only do they look good, but they blend with the doors so well that once the door is closed, it’s virtually impossible to tell if there is any sensor on it.

Alright, now discuss the second part. Durability. They are much more durable than the other sensors. Why is that? Because they are built like it and even more are fixed incredibly tight that unlike other sensors they won’t fall off twice every year.

There is a kind of third point which we can touch upon here. When the sensor falls, it rings a false alarm. Believe us, a false alarm won’t make you or your neighbours feel good if it goes off in the middle of the night. So we can say, they are less annoying as well.

How to remove wireless windows and doors sensors?

First, let’s talk about the tool you’ll need to remove these sensors. Make sure to have one of these tools. Razor blades, a silicone digestant,

or sealant removed, a putty knife or paint scraper, or a Phillips-head screwdriver.

Now, let’s get to the step-by-step process.

Step 1: Identify whether the silicone lining of your sensor is light or heavy. You can do this by touching the edges of the sensor.

Step 2: If the lining is light, you can take the sensor off by using a razor or a knife. But, be sure to be gentle.

If the lining is hard, then you should use WD-40 to remove the lining. Again, be careful. You can remove the hard silicone lining with a razor as well, but you’ll most likely damage the door or a window so we strongly recommend using a WD-40.

How to remove the wired windows and doors sensor?

The process is exactly the same. Almost exactly the same.

You’ll need a Phillips screwdriver to remove the wires from the sensor and the control panel. Once you’ve done this, you can pull the wire off using your hands.

How to remove recessed windows and door sensors?

Step 1: Check if the sensors are recessed within the frame.

Step 2: If they are not recessed within the frame, taking them off will be pretty easy.

What if they are recessed within the frame? Then, lose the corners just a little by using a screwdriver. Then, remove the magnet first before taking off the sensor.

Your sensor may be installed directly into the wood or sheetrock. If that’s the case, then use the screwdriver to remove magnet or a sensor plate before removing the wiring.


By reading this post, you’re guaranteed to find the answer to your question. It doesn’t matter what type of sensor you own, there is a solution for each type in this post.
