Alarm-D Pro

Alarmed D-Lock


The Alarm-D Pro is a maximum-security U lock which 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 Bicycle 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 has a key replacement service. When you buy your Alarm-D Pro, simply note down the number which comes attached to the keys on a metal tag. Keep this in a safe place, then in the event that you are unfortunate enough to lose all your keys, it will be possible to get a new key made up for you.
