# The Alarm-D Pro
The Alarm-D Pro is a maximum-security U lock that comes with its own easy-to-fit carry bracket. The Pro model has an upgraded and thicker lock body and, combined with a 14mm special hardened steel shackle, the lock comfortably surpasses the Sold Secure Pedal Cycle GOLD standard. It also has a 120dB weatherproof movement and shock-activated alarm, which will scare off any would-be bike thief.
The Alarm-D Pro DUO (model LK349) comes with a chunky 1.2-meter looped cable, to help extend its reach and to secure both wheels and frame.
The Alarm-D Pro has a key replacement service. When you buy your Alarm-D Pro, simply note down the number attached to the keys on a metal tag. Keep this in a safe place. In the unfortunate event of losing all your keys, it will be possible to get a new key made up for you.
