Lock Rekeying in North Tonawanda, New York
Rekeying is the most useful thing most people have never heard of. Instead of buying new locks, the internal pins in the lock you already own are changed so your old keys stop working and a new key takes over. Same hardware, same look, new key, a fraction of the cost of replacement. North Tonawanda sits where the Erie Canal meets the Niagara River, and the city still works the way a canal town works. Webster Street and the Gateway Harbor waterfront fill up all summer, the Wurlitzer building and the carousel factory anchor the industrial history, and the residential streets off Oliver and Payne are dense, walkable and old.

What Makes North Tonawanda Different
Two things shape lock and key work here. First, the water: boat traffic on the canal and the river means marine keys, dock boxes and slip locks alongside the usual house and car work. Second, the housing age. A lot of the stock off Oliver Street and Payne Avenue predates the war, which means original hardware, doors that have settled, and frames that need attention before anybody talks about upgrading a lock.
We cover Webster Street, Gateway Harbor and the canal waterfront, the Oliver Street and Payne Avenue neighbourhoods, and the Sweeney Street corridor, and everywhere in between.
Landlords: doing the maths on turnover
If you own a two-family here and both units turn over every couple of years, you are looking at a rekey every twelve months on average. Done reactively, that is a callout each time. Designed once as a small master system, a turnover becomes re-pinning one unit cylinder and, if you want to be thorough, the common entry. The setup cost is modest and it pays back within a few tenancies, quite apart from finally being able to answer the question of how many keys to your building exist.
Old cylinders that should be replaced rather than rekeyed
In pre-war housing we regularly find cylinders worn to the point that keys turn with a wobble and occasionally stick. Rekeying one of those preserves a lock that is already on its way out, and you will be calling somebody again within a year or two. We will tell you when that is the situation. Usually the sensible plan on an older North Tonawanda house is to replace the one or two tired cylinders outright and rekey the rest to match them, so you end up on a single key with no weak link.
Two-family houses and the shared-door problem
A large share of North Tonawanda’s housing stock is two-family, and the shared front door creates a security question most owners never quite resolve. If the upstairs and downstairs tenants both hold a key to the common entry, then every turnover in either unit puts a key to the whole building into circulation. Rekeying just the departing tenant’s own door does not solve it. The workable structure is a small master system: each unit keyed individually, the common entry keyed so both units’ keys operate it, and the owner holding a single key that opens everything. Then a turnover means re-pinning the common entry and one unit rather than the whole building, and you always know how many keys exist. For owner-occupiers in these houses the same logic applies to the basement and the garage, which in this part of the city are very often shared as well.

Questions North Tonawanda customers ask us about lock rekeying
Can all my locks be put on one key?
Usually yes, as long as the hardware is compatible. Front, back, side and garage doors on a single key is one of the most common requests we get and one of the easiest to deliver. In North Tonawanda we cover the whole city including the waterfront and the Oliver and Payne neighbourhoods.
I just bought a new-build house. Do I really need this?
Yes, and arguably more than an older house. Construction keys circulate among trades for months, and every home in the development may have been keyed by the same crew. Rekeying on move-in is cheap and it closes all of that. Tell us upper or lower flat when you call; a great many addresses here have two front doors.
How long does rekeying take in North Tonawanda?
A typical house with three or four locks takes well under an hour on-site. We do it while you wait and hand you the new keys before we leave. If a boat or trailer is involved as well, mention it and we will bring blanks for the lot in one trip.
Can you rekey locks from different manufacturers to one key?
Sometimes, if the keyways are compatible. Where they are not, the usual answer is to replace one or two cylinders so everything matches, which is still far cheaper than replacing every lock on the property. Parking is tight in the older grid, so let us know which side of the street you are on.
