Summing It Up. To summarize this issue, a Schlage lock blinking red can be caused by various issues, such as low or critically low batteries, incorrect user codes, and programming errors. The less likely issues are firmware glitches or hardware damage.
If your Electronic Door Lock is beeping and the buttons are flashing red, this means that there's been some kind of error or the batteries are low. If the batteries have already been changed and you still see a red flashing light when you try to use the lock, there could be an error with the lock.
According to the Upgraded Home website, the constant blinking means the battery is already dead and needs replacing. A flashing red followed by green light and beeps indicates low battery power and will have to be replaced with new ones soon. To replace them: Turn your lock around so that you can see the back of it.
To test, enter the default PIN (13579 and “#”). The Schlage button will blink and the lock will unlock. The default PIN is automatically deleted when a new programming credential is created. If you press the default PIN code on a new lock and the code is not accepted, the lock has already been programmed.
The default programming code is printed on a label on the programming guide that came with your lock. If you do not have access to the guide, remove the lock from the door and look on the back of the lock for a label containing the default code.
Keypad Not Working
Make sure you didn't enable Vacation Mode: If vacation mode is enabled, the keypad will not work. Restart or reset your lock: Try unclipping the batteries and reconnecting them to see if a basic restart helps. Otherwise, try a full factory reset on the lock.
If the battery is dead and you need to unlock the door, you can perform an emergency battery jump start. Follow these steps to perform an emergency jump start. Connect a new high-quality alkaline 9-volt battery to the contacts below the touchscreen and listen for the long beep.
Replacing the Battery in Your Keyless Lock
Many locks utilize a 9 volt alkaline battery, but other locks such as the Trilogy PDL7100 use four C batteries instead. Simply replace the battery (or batteries), making sure that it is firmly secured in its compartment.
Battery life
Schlage smart locks are powered by 4 double A batteries that only need to be changed once a year.
The lock comes preset with two unique default User Codes. They may be found on the stickers, one on the back of the keypad assembly and one on the front of this User Guide. Used to unlock the lock. These four digits must be different from the first four digits of the Programming Code.
The majority of Schlage locks will have the company's name stamped into the exterior face of a deadbolt. Check the external side of your door to see if you can find the name stamped on the lock. If you cannot find the name on the deadbolt face, take a close look at the latchplates.
It provides room for four AA batteries, which Schlage says can last up to six months when the lock is used on Wi-Fi or up to a year if you use it with Thread.
