Rated 3 out of 5 by from Better than a normal padlock I bought 4 of these as a deterrent. They're great when they're dry but terrible when it's raining/when they're wet.

When you unlock with the key I assume the alarm sounds. Does it stop when the key is put in.

Before I order one of these locks can you tell me if the sounder is located on the top or underneath. The reason I ask is that I recently bought one from another supplier but rain got into the sounder and muffled the alarm and Rolson tell me that the design has now been changed.
Asked by: Bruce Larner
This product has the sounder located at the top of the unit.
