The weather resistant E-Plex 5000 series from dormakaba (formerly known as Kaba) is an extra heavy duty electronic digital lock solution suited for both internal and external applications. The lock can be easily programmed via the keypad and does not require the lock to be removed from the door. Alternatively, the lock can be programmed using an optional Microsoft Excel-based software. With no wiring required, the E-Plex 5000 is easy to install. The adjustable anti-tamper lock out feature lets you choose how many invalid Pine code attempts to allow before they are locked out.
