You don't need an antique lock specialist, any competent locksmith can easily open and fit a key to your lock. If want to avoid the expense, as you suggest; you could drill out the lock cylinder to open the lock and then replace the thus destroyed cylinder.

    I just reviewed my above post and found I made an error, there are ten different possible depths of cut or pin lengths (0-9) per chamber on the Yale #8 key, thus the number of different theoretical key changes would be 105=100,000. Or, expressed differently; ten x ten x ten x ten x ten = 100,000. Sorry for the confusion.
