How To Remove Alarm Sensor From Door

Last updated: August 22, 2021


It is easy to remove the alarm sensor from your door. Simply delete the zone and take off any magnet or wiring that may be attached to the top of it. For wired alarms, you will need to disconnect them first before removing anything else, so make sure not to touch all those wires!

The most important part of a door alarm system is the sensor and magnet. These two parts are installed separately on or inside your doors to make sure that if an intruder tries to come in, they’ll trip one of these sensors before entering! If you ever need to remove either piece from their place for any reason, you can use a screwdriver.

Complete the below-mentioned steps to remove an alarm sensor from your door:

Clear the zone. To delete a zone on your panel, you’ll need to first go into the programming menu and find the section for zones. Once there, locate the specific zone that needs deleting by using either its number or name from within this list of all installed zones available. Then enter in your Installer Code if prompted before proceeding with the deletion process according to instructions given in the model-specific instruction manual!

Remove the wires. To get rid of a door alarm sensor, disconnect and remove the wires. Recessed sensors will require you to take it out from the frame to access these wires. You’ll need a screwdriver for this step – just unscrew with one hand while holding onto your device with another so that nothing falls into an opening in your wall!

Take off the sensor. Remove the door sensor from your frame by following one of three methods: if it is recessed, pry or pull it out; for tape-mounted sensors, remove the adhesive and peel off any residue that has been left on your doorframe. If screws have been used to secure a surface-mounted sensor, then you will need a screwdriver to loosen them before removing them.

Take off the magnet. Since the magnet is mounted in a variety of ways, take it off using one of these three methods: if the magnet has been recessed and you can’t see any adhesive on either side when you remove it, then use prying or pulling to get rid of. If there’s foam tape securing that sucker around your door, just cut through both sides with scissors until they come free from its mounting surface. And lastly, for those pesky screws holding down magnets? Just unscrew them!
