Is your garage door stuck or not closing properly? If you’ve been having trouble getting your garage door lock to work properly, you’re not alone. Garage door locks are complex pieces of machinery, and there are a variety of reasons why they might not be functioning as expected. Let’s take a look at some of the most common culprits for when your garage door lock stops working.
1. Something is blocking the way.
Garage doors have a reversing mechanism that prevents them from crushing objects in their path. If your garage door closes partially and then reopens, this can be caused by objects on the ground blocking their path, such as rubbish bins or toys. It could also be the result of debris on the tracks preventing the rollers from moving forward. Small items such as rocks, gum, or mud buildup may be included. If the door collides with even a minor object on the track, it will return up to avoid crushing whatever is beneath it.
2. Dead transmitter batteries.
This may seem obvious, but your garage door transmitters require power to function. If your transmitter’s batteries die, the transmitter will be unable to send a signal to your garage door to open.
Changing the battery in your garage door transmitter is a simple process. Most allow you to remove the battery by sliding the door on the back of the transmitter open. Others may be screwed in to keep the battery more secure, so this type of transmitter will need to be opened with a screwdriver.
3. Dirty or misaligned sensors.
If your garage door opens normally but does not close when you press the button on your remote, it is possible that your sensors are dirty or out of alignment. When something crosses the invisible beam along the ground beneath the garage door as it closes, the door will automatically reverse and open again.
This is in place to potentially save lives by ensuring that the door does not close on someone, such as your child or a pet. If the sensors are dirty, they may be unable to see each other and, as a result, cannot send a beam back and forth, causing your garage door to believe it should not close.
If you clean them and they still don’t close, it could be because they aren’t properly aligned. Place them at the same height and adjust their angles to match.
Rust spots on your key or on any part of your locking mechanism could indicate corrosion which will impede its ability to function properly over time if left unchecked so make sure these areas are kept clean and lubricated regularly in order to prevent this issue from occurring in the first place.
5. Malfunctioning Springs
Springs play an important role in how smoothly a garage door opens and closes but they too can sometimes malfunction due their age or prolonged use; if these springs become worn out then they’ll need replacing in order for everything else within your locking system (as well as within your entire garage door) function optimally once again.
There are many potential causes for why your garage door lock isn’t working properly, ranging from worn out locks all the way through faulty wiring issues – identifying which one is affecting yours requires careful troubleshooting but once found should help resolve whatever problem(s) you’re facing quickly and easily. Homeowners should always remember that prevention is better than cure so don’t forget about regularly cleaning and lubricating any external components as well as checking all internal wiring connections every few months just in case there’s something amiss that needs attention right away.
