The Craftsman garage door remote is an amazing device that facilitates convenience and ease in opening and closing the garage door. In some instances, due to impact or mishandling of the remote, its battery can be drained. If this occurs, you might need a garage door opener remote battery replacement.  There are steps you could take to replace the battery so the remote will function again.

Changing the battery in a Craftsman garage door opener remote is a quick and easy project that can be done by anyone. Here is what you need to know:

Step 1: Locate the seam in between the garage remote casing. Stick the flat head screwdriver into the seam and twist it gently to split the remote case in half.

Step 2: Once the garage door remote casing is split into two pieces, remove the old battery by sliding it out from its battery tray. You won’t need a screwdriver in this stage as the battery can be pulled out by your fingernail. You want to make a note of how the old battery was inserted into the battery tray before removing it.

Step 3: Grab your new craftsman garage remote battery and slide it into the battery tray. Make sure to follow the same direction or pattern the way you removed the old one. This Crafstman 315 device model uses a CR2032 3v lithium battery which can be purchased at any hardware store or online like Amazon.

Step 4: Once the battery is inserted, place both halves of the remote casing together and snap them gently to lock each other in position. You can now test your newly-replaced garage door opener by pressing on its button while pointing it at the receiver installed outside or inside your house. If you notice that it works properly, then you have successfully replaced your Craftsman garage door opener remote battery.

Why is the garage door opener remote not working after replacing the battery?

If after replacing the old battery with a new one and it still does not function properly, there are several factors that may be causing this to happen, which includes:

– The replacement battery is not of the same type or is not compatible with your garage door remote.

– If there was any damage done to the remote control while replacing its cover, some buttons may have stopped working.

– It may also be possible that the remote’s circuit board has been damaged. In such a case, it is best not to attempt fixing the unit yourself but instead get in touch with the local experts who can fix this for you cheaply and efficiently.

-If it does not work, there may be an issue with the connection between your remote and its receiver box, which you need to check by turning off all power sources of both devices for at least 30 seconds before powering them up again.

-You might need to reprogram your remote.

What are the signs of battery drain in a garage door remote?

One sign of battery drain is that the garage door will sporadically have a hard time closing. The remote is unable to send out the signal to the garage door opener, which will then cause it to go off track.

Another sign is an inconsistent operation, such as when it takes multiple tries to open the door. A garage door remote that operates inconsistently is also a sign of low battery and should be replaced immediately.

And the final sign is when the remote will not work at all. If it fails to open or close the garage door, then it is time for a replacement.
