"I installed this security lock and at the start it worked well. This was during the summer when the weather was decent. However, since the weather has turned wet and cold I noticed that the lock was getting harder to close. It is now very difficult to close and can take up to 30 minutes now. I actually thought I was not going to get it closed again which is not at all good for a security lock!!! It's a shame but I think it's a risk buying an integrated lock and will not be doing this again."
