Removing a garage door lock from the outside can be a tricky task, so it’s important to properly prepare before you start. First, you’ll need to gather the right tools and supplies, such as a drill and the corresponding drill bit, a flat head screwdriver and a pair of pliers. Once you have all of the necessary tools and supplies, you should plan out your approach. This will help you to ensure that you are able to complete the job efficiently and safely.

Gather the necessary tools

Whether you need to remove the lock from the outside of a garage or free a door that has become stuck, having the right tools and supplies can make the job easier and quicker. Before attempting to remove the lock, take a few moments to gather the necessary tools for the job.

To Remove Lock:
-Phillips head screwdriver
-Flathead screwdriver
-Long needle nose or flat pliers
-Vice grips (optional)

Once you have these tools in hand, you can begin dismantling your garage door lock and replacing it if necessary. Some may find lubricating grease helpful in freeing up sticky locks or rust covered bolts; however, this is an optional step based on personal preference.

Wear safety gear

Before removing a garage door lock from the outside, it is important to wear appropriate safety gear. Wear typical protective work gear such as long pants, closed toe shoes, safety goggles and gloves to protect your hands and eyes while you are working. Additionally, take the time to clear any object that may be in the way of your job or create an environment which is safe for you to work in. It is also important to make sure that no one else will be harmed if any tools are dropped or used carelessly. Once you have taken these steps, you should be ready to begin the removal process.

Removing the Lock

Removing a garage door lock from the outside can be a tricky process. Depending on the type and brand of lock you have, the techniques will vary. It’s important to understand the correct steps so that you can remove the lock without damaging it. In this section, we’ll discuss the steps you need to take to safely remove a garage door lock from the outside.

Disconnect the power source

Before attempting to remove the garage door lock from the outside, it is important to ensure that the power to the door opener has been completely turned off. To do this, you should locate either the power switch or circuit breaker on your wall and switch it off. If you are still unsure as to how to disconnect the power source, consult manufacturers’ instructions or contact a trained technician for further assistance. Once the power is safely disconnected, you can then proceed with removing the lock from your garage door.

Remove the screws from the lock

Removing the lock from your garage door from the outside is a straightforward task that requires minimal tools. Before beginning, make sure you have a flathead screwdriver and something to pry with, such as a putty knife or pliers.

To begin, use the flathead screwdriver to remove the screws that hold the garage door lock in place on the outside of your garage. Most locks today are mounted using screws or bolts, and there may be 2 or more depending on which kind of lock you have. Carefully loosen each one and then remove them completely.

Once you have all of the screws removed from your garage door lock, you can now gently pull it away from its mounting location. You should be able to do this by wiggling it back and forth gently until it gives way and pulls free. Be sure to keep track of any springs or other components that may come off during this process as these will need to be re-installed when replacing a new lock in its place.

Pry open the lock with a flathead screwdriver

For this method to work, you will need a flathead screwdriver and two strong objects to hold the garage door open. Start by prying up the outside cover of the lock with a screwdriver. If your lock looks more like a padlock, use the screwdriver to turn it clockwise. Lift up on the lock while turning it and it should eventually come off of the base plate. Doing this will unlock the garage door from inside and you should be able to pull out the bolt that secures it.

Once the bolt is removed, use several pieces of cardboard or other padding material to block off any gaps between where your door meets its frame and where any windows are located. This will keep debris from entering your garage as you create a slight gap between your door and its frame.

Using two sturdy objects such as blocks or bricks, slightly raise your garage door’s opening about half an inch (12 mm) from its normally closed position and carefully insert either end of your flathead screwdriver into each side of the gap. You may need assistance in doing this correctly. The goal is to move both handles of the locks outward using your flathead as leverage so they can be removed from their brackets without exerting too much force on either side.

Replacing the Lock

Replacing a garage door lock from the outside can be a difficult task. It can be especially tricky if you don’t know the correct way to go about it. Fortunately, there are some steps that you can take to make sure that you get the job done correctly. In this article, we will go over the steps that you need to take when replacing a garage door lock from the outside, so you can do the job right.

Measure the length of the lock

To replace the lock, you need to measure the length of the lock to determine the size of replacement you will need. The standard lock length is 30mm or 1-3/16 inches. You can use a ruler or measuring tape to measure from one edge of the mounting plate where it meets the door frame to the center of the keyhole in order for proper measurement. Use this measurement as a guide for selecting an appropriate replacement lock. When replacing locks, be sure that your replacements are made of sturdy material and are properly secured with screws that cannot be easily removed.

Purchase a new lock

When replacing a garage door lock from the outside, the first step is to purchase a new lock that fits your needs. Depending on the type of garage you have, different styles of locks may be available. Choose a robust and secure lock that fits into the existing mechanics of your garage door. There are many types of locks available, from combination locks to keyed entry systems. Consider other security features such as deadbolt locks, biometric access, and digital locks for added protection against unwanted intruders.

Evaluate all security options available, assess your home environment and choose which lock best suits your needs before purchasing a replacement lock for your garage door. Additionally, make sure that whichever lock you choose meets all applicable local building codes and safety requirements so it will function properly within your existing setup without compromising its structural integrity.

Install the new lock

Once the old lock has been removed, you are ready to install the new one. Carefully inspect the new lock to be sure it fits properly into the existing hole. It should fit snugly and be secure. If the latch does not fit securely, you may need to file down the hole opening slightly. Be careful not to damage it.

You will need either a screwdriver or wrench to tighten and secure the replacement lock in place. Follow any additional instructions from the manufacturer for details on installation and use of your new garage door lock. Make sure that all pieces of hardware are firmly secured in place before testing

Finishing Up

Removing a garage door lock from the outside of your garage can be a tricky process, but it can be done. With the right tools and patience, you can remove the lock in a few easy steps. This article will discuss how to finish up the process by replacing the lock and securing the door. Let’s get started.

Test the lock

Before attempting to remove the garage door lock from outside, it is important to first test the lock to make sure that it is indeed stuck. A stuck lock may be due to defective components or rust, resulting from moisture or humidity. If the lock moves easily when you attempt to turn the knob with a key, then use a lubricant on all parts of the lock before continuing. Be patient and gentle when turning the knob with a key as forcing too hard can ultimately cause more damage.

Re-connect the power source

Before attempting to reconnect the power source, make sure that all of the cables are in their proper positions and are secure. Depending on the type of garage door lock you have, it is possible that more than one electrical cable may be involved. Start by connecting the power supply first. If your door has a keypad and wireless opener, then you should install the battery first before connecting to the power supply.

Once the power supply is connected, ensure all cables are connected properly and securely. Carefully attach all fasteners including screws, nuts and washers as needed to attach any moving parts within or near the lock system itself. Ensure nothing is loose prior to switching on the power source every time you complete a job like this. Finally double-check for any damages that may have occurred due to installation or prior use as it will be important for safety reasons later on.

Clean up the area

After you have removed the lock from the door, be sure to clean up the area around it. This includes removing any broken pieces that may have come out and getting rid of any sawdust or shavings that may have resulted during the process. If you are re-installing a new lock, make sure to check the fit and make any necessary adjustments to ensure a secure installation. Use an appropriate lubricant on moving parts and treat rusty surfaces with an anti-rust spray. Finally, make sure to test your newly installed garage door lock by operating it several times before closing up for good.
