High-quality Fingerprint lock and has a port for an A/C Adapter.  (The AC adapter and 3.3 foot cable are not included. if needed, order RF-Plug). The unit operates on 4 AAA batteries and/or the optional A/C Adapter (NOT INCLUDED). Easy to install. Instructions and screws are included. Keep your valuables safe and accessible!

The standard cable between the lock and sensor is about 3.5" long.  We have another cable that is 20" long that can be added as an option.  If you need to order the cable separately, its Part# KR-FL-20". 


4 AAA power the unit with a working battery life of up to 50,000 cycles. If battery life starts to get low, a low voltage alarm will sound to indicate a battery change is necessary. Total battery drainage will result in the lock being unable to lock ensuring you will never have a locked out situation. Each lock features spring releases that will give the drawer, cabinet etc. a push to open itself (spring release can be removed). Easy to follow setup instructions included will guide you to use the programming prints.  All stress points are reinforced with steel.  No PC necessary
