Dave began his career as a locksmith nearly two decades ago. He started off as a self-employed locksmith on general lock changes and openings etc. After a couple of years in the trade he started to work on utility warrants which he has been doing for approximately 16 years now. He has been opening electric roller shutters for most of that time but only if they had a winder on them. Along with Simon Mason-Newman they first trained themselves on how to open electric shutters by any other means, both legally and safely. They now train other locksmiths (who generally work in the warrant trade) their methods and procedures.
