We're looking at a repossessed house at the moment, and while the main external doors have all been changed* and are accessible via key, there are patio doors for which there are no keys (eurolock profile).
- by some rough arsed b'stard who, it seems, jemmied the doors open and cut chunks out of the front door to get to one of the upper latches (breaking several metal locking plates in the process)
Are there any easy ways of replacing these without a locksmith ? - we'd have access to both sides of the door(s), so if there was something you could do from the internal side such as removing the plate around the handle / lock, it shouldn't be an issue.
Failing that, how hard is it to drill the buggers, and do you aim for anywhere in particular in the lock ?
