Welcome to our Technical Support Section:


Types of Garage Doors:

  • SureLock is designed for Standard Sectional Roll-up Garage Doors

  • But can be adapted for custom installations in some cases

  • Please contact us as needed to confirm


Mounting Location:

  • SureLock can be mounted on either Side and on any wheel you choose

  • SureLock can also be mounted Horizontally if needed


White Wire:

  • Do not use a Staple Gun (can result in Short and damage your SureLock Electronics)  Note: See “Continuity Test” section


Blue LED:     

The Blue LED on the Power-Supply only lights upon activation of the Garage Door

Red LED:      

The Red LED on the Vibration-Sensor Flashes on any Vibration or Noise

 (You can/will notice the Red LED Flash on any Noise/Vibration in the Garage)


Attaching Lock-Bar:


Attaching White-Wire:


Manual Reset:

Occasionally there might be a need to perform a full reset to your SureLock

This is done by Fully unplugging the Power-Supply from AC Outlet and 4Pin Harness for 20 to 30 seconds…Then you can simply re-connect

At this point you need to Cycle your Garage Door Opener fully two(2) times without any interruptions !! – We use this to lock in the Current Draw, and timing of you Opener


Mounting Vibration-Sensor on your Garage Door Opener:

Please mount the Vibration-Sensor directly on the Garage Door Openers Metal Brackets (The same ones used to mount opener to the Ceiling)

SureLock’s Vibration-Sensor should be mounted “ON” or as close to the Openers Motor as possible


Backup Battery Harness:

Quick Tip: Snip Door Cover to create/allow harness access to enter Battery compartment and connect to Battery


Continuity Test for SureLock’s main unit:

Start by removing the “White-Wires” from SureLock’s Vibration-Sensor

With your Voltmeter test the Resistance between the two White-Wires

  • We are looking for 3.8 to 4.2 Ohm’s of resistance under normal circumstances

  • If you are seeing a Short – You need to check the full length of the White-Wire for any nicks / shorts (This is easily created if a Staple-gun was used during installation)

  • If you are seeing a completely Open circuit, Check to confirm the White-Wires have not been severed


If you are unable to find the issue causing you problems, please don’t hesitate to contact us:
