ARREGUI CI10P-AL Invisible Door Lock with Alarm System and 4 Remote Controls, Keyless Additional Lock with Alarm, Electronic Security Lock, Door Lock, Anti-Theft Silver

Theft protection: the lock is attached inside, so burglar does not know about its existence or installation location, which makes it difficult to break. The 110 dB loud alarm sounds as soon as the door vibrates, is bumped or forcibly opened. Additional security for doors: this additional lock is made of steel and is intended for apartment and front doors, as well as for shops or offices where extra security is desired. It can be attached to wood and also on metal doors. Includes 4 remote controls: the e-lock is opened and closed using the remote controls. The remote controls can be reprogrammed if one of them is stolen or lost. Additional remote controls are sold separately. Impossible to stay excluded: the lock emits an acoustic warning signal when the batteries are almost empty, and cannot be closed until the batteries are changed. Extremely safe and easy to assemble: radio frequency remote controls, the encryption of the data is carried out by rolling codes, which are therefore not copiable by frequency tuners. Easy to install, no cables, mounting hardware included., Manufacturer: ARREGUI
