When you buy a business or take over a commercial space, you inherit far more than the lease and the inventory — you inherit every key that was ever made for the place, held by every former employee, contractor, vendor, and previous owner. You have no way of knowing how many copies exist or who still has them, which means until you act, your security is an open question. For Norfolk County and Greater Boston business owners, rekeying should be among the very first things you do, and here is why it matters and how to do it right.
Taking over a space means taking over an unknown key situation, and rekeying is the only way to reset it to a known, controlled state under your authority.
The keys you cannot account for
Over the life of a commercial space, keys accumulate steadily — handed to employees, copied for managers, given to vendors, and rarely all returned. When you take over, every one of those keys may still open your doors, in the hands of people you have never met and cannot identify. You cannot manage what you cannot see, and an unknown number of outstanding keys is a serious, ongoing security gap. Rekeying invalidates them all at once, resetting access to a known state that you control from day one.
Rekeying versus replacing
You usually do not need to replace all the locks. Rekeying changes the internal pins so old keys stop working and new keys do, at a fraction of replacement cost, and if the existing hardware is sound, it secures the space affordably. Where locks are worn, damaged, low quality, or simply inadequate, replacement and an upgrade make more sense. We assess the inherited hardware and recommend rekeying sound locks while replacing only what genuinely needs it, so you secure the space without overspending on hardware that was fine.
Do it before you open
The ideal time to rekey is before you take occupancy or open for business, so the very first day you operate, you alone control access. Waiting leaves a window where unknown keyholders can enter at will. The CISA security guidance emphasizes establishing access control from the outset rather than after a problem. We work with new owners to rekey on the takeover timeline, so control of the space is firmly yours from the start rather than weeks into operation.
Keying alike and master systems
A takeover is a good moment to rationalize a confusing key situation. If the space has a jumble of different keys for different doors, rekeying alike — or building a master key system — brings order, letting managers hold keys that open what they need while sensitive areas stay restricted. We design the rekeyed system around how you will actually run the business, not how the previous owner happened to leave it, so the access structure fits your operation.
Establishing key control going forward
Rekeying is most valuable paired with key control going forward. Restricted keyways prevent unauthorized copying, and a documented key-holder list keeps you aware of who has access as staff change over time. The OSHA workplace safety standards assume controlled, functional access to a workplace. We help new owners establish key control from the start — restricted keys and clear records — so the access you reset by rekeying stays under control rather than drifting back into uncertainty.
Do not forget the back doors
New owners often focus on the front entrance and overlook rear and side doors, storage rooms, mechanical spaces, and other access points — exactly the doors an unauthorized keyholder might exploit unseen. A thorough rekey covers every door, not just the obvious ones. We map all the access points of a commercial space and rekey comprehensively, so there is no forgotten back door quietly opening to an old key while the front entrance is secured.
Alarm codes and access credentials
A takeover is also the time to address the rest of the security picture. Alarm codes known to former staff should be changed, and any access-control credentials reissued, alongside the rekeying. The Insurance Information Institute notes how security measures affect protecting a business. We help new owners coordinate rekeying with alarm and access-control updates so the entire security setup reflects the new ownership rather than the old.
Securing your investment
Rekeying after buying a business is not optional housekeeping — it is the step that turns an unknown, inherited key situation into access you control. Done before you open, covering every door, and paired with key control and updated credentials, it secures your investment from day one.
