PLEASE NOTE:

Replacing batteries, especially of cylinder type locks, requires special tooling and is usually done by a certified installer. If you don't know who your installer is or want to find a new one, please locate a dealer using the tool on the "Get in Touch" page.

If you are equipped with the proper tool:

Use the cylinder tool to open the head of your cylinder. Pull the white tab to remove the battery. Replace the battery with a new one.

When you put in the battery, you should hear 2 short beeps. If you don't hear the beeps, check if you inserted the battery correctly. Close up the head of your cylinder using the tool.
