01Locksmith foundations: authorized service, compatible hardware and verified function
Locksmith work begins with the customer's authority, the opening or equipment involved and the function that must be preserved. Identify the lock type, door or container, applicable hardware information and the agreed scope before choosing a service method. A mechanically successful change is not a complete result if it compromises egress, fire protection, accessibility or the customer's key-control plan. Records and respectful handling of private information are part of professional work.
