To replace the batteries in non-weatherized or weatherized units, the electronics module must be removed from the door and the battery cover removed by unscrewing the screw in the center of the battery cover. For non-weatherized units batteries need to be replaced with Alkaline type. Use Of Lithium type batteries will not only void the warranty, it will also nullify the UL listing on the lockset. For weatherized units two special battery packs need to be replaced. To purchase replacement weatherized battery packs contact us. If each cell is removed one at a time and its replacement installed, so that only one cell is absent at any time, the data in the memory will be preserved. Weatherized units may lose their memory when changing batteries because more the battery is being removed at at time. If memory lose does occur on either non-weatherized or weatherized you must reset the lock.  

Note: You must replace the batteries from Left to Right and one at a time.

Normally the batteries should be replaced soon after the red indicator starts to flash twice after the green entry indication. However, if allowed to discharge after this indication for well over a thousand entries, the battery level will be low enough to force the lock into Shutdown access level. It will still respond to the Programmer code, thus entry can be gained so that the batteries can be exchanged. Note: After the new batteries have been installed, the Programmer must reset the access level to the desired level using the Mobile Device.
