FAQs
Why is my Trilogy door lock constantly beeping after a battery change?
When changing the batteries in your Trilogy lock, ensure the correct polarity with each battery. If a battery is installed with incorrect polarity, the lock might seem to power up correctly but in fact will not receive the correct voltage. In addition, always use alkaline batteries ONLY. Do NOT use Ni-Cad or lithium batteries.
If you are certain that you have followed the above instructions and your Trilogy lock is still constantly beeping, call Alarm Lock Technical Support.
