ALEKO's Electric Lock provides added security for your gate, which in turn will give you additional peace of mind. It unlocks and locks automatically as your gate opens and closes. Installation is quick and easy, and a manual release key is included so that you can open your gate even in low-power or no-power situations. Recommended for gates over 7 feet long. Our lock is ideal for animal enclosures, businesses, or anywhere else that could use a little extra protection and security.
