Replace new batteries with the old ones. Do remember to check for polarities. Also ensure that you are using only the alkaline batteries as advised by the company.

If alkaline batteries are not used, then you might see your batteries draining fast.

Reconnect Battery Pack & Cover

Insert the battery tray (with new batteries) back and put the cover on. Usually on all Schlage models, there will be small metal strips on bottom of battery tray. These metals strips should face you when you are inserting the tray back again.
