The LiftMaster 3245 is a garage door opener that can be used to replace your torsion spring. To do this, you will need to remove the old torsion spring and install the new one. You will need to use a screwdriver or drill to remove the old torsion spring, and then install the new one. The installation process should take about 30 minutes, but it may vary depending on your skill level.
