Re: Only cracking I have done is
Took the information to our high street independent key maker - a week later he supplied a key that worked
We recently had our front door replaced and the new one had uprated "security" locks - for which the supplier wanted £35 per duplicate key (it only came with two keys) and assured us that we couldn't get them anywhere else.
One swift trip to our local independant key cutter and we had 6 extra keys - for the princely sum of £10. All of which worked.
