When Changing Your Door Locks Is the Right Call

The work at the door is usually quick. Deciding which openings need it, and whether the existing hardware is worth keeping, is the part homeowners get wrong. All Hour Locksmith, a Salt Lake City based locksmith, treats changing door locks in Salt Lake City as routine work for homes and businesses. The same mobile visit can take in rekeying, lock repair, or an emergency lockout, and the company offers a free consultation on choosing residential locks.

What Makes a Lock Worth Replacing Rather Than Servicing?

A lock that turns roughly is often telling you about the door, not the cylinder. Genuine wear inside the mechanism happens, but misalignment causes far more sticking than worn pins do.

Replacement is the better answer when any of the following is true:

• The cylinder is loose in its bore and rotates when the key turns.
• The key has to be lifted, pushed, or jiggled before the bolt moves.
• Corrosion has reached the point where the bolt drags in the strike.
• The opening has a knob lock with no separate deadbolt above it.
• Nobody knows how many keys exist or who still holds one.

That last point matters most and gets ignored most. Keys copy quietly, and no household tracks every duplicate made across twenty years of ownership.

Rekey or Replace: Which One Does the Door Need?

Rekeying changes the pin stack inside an existing cylinder so older keys no longer turn it. Replacement swaps the whole assembly for new hardware. They solve different problems and cost different amounts of disruption.

Rekeying suits hardware that is mechanically sound and visually acceptable. It is fast, it keeps a matched finish across the house, and it can put every exterior opening on a single key.

Replacement earns its keep when hardware is failing, when a door has no deadbolt at all, or when a keypad is going in. Before booking anyone, it is worth checking a technician against locksmith credentialing standards rather than a search ranking.

Which Doors Get Skipped Every Single Time?

Front doors absorb all the attention. The openings that quietly get missed are more predictable than most people expect.

1. The garage-to-house door, frequently the weakest entry in the whole building.
2. Basement and cellar accesses running on decades-old hardware.
3. Sliding patio doors, where the factory latch is not really a lock.
4. Detached garages and sheds holding tools worth more than the structure.
5. Gate locks and mailbox locks, both of which travel with old key rings.

Hardware is only part of the picture. Lighting, sightlines, and home and neighborhood safety habits shape how a property reads from the sidewalk. Cameras and fencing belong in the same conversation, which is why a wider run at home privacy improvements tends to pay off better than one new deadbolt.

How Does the Door Itself Change the Hardware Choice?

Three measurements decide what will actually fit. Getting one wrong turns a quick swap into a second trip to the store.

• Backset, the door edge to bore center, is 2 3/8 or 2 3/4 inches on most homes.
• Bore diameter is 2 1/8 inches for a standard cylindrical lock body.
• Slab thickness runs 1 3/4 inches on a typical exterior door.

Measure before buying. A mismatch on any of the three sends the hardware straight back.

Sagging doors are the other constraint. If the bolt no longer meets the strike plate squarely, new hardware binds exactly the way the old set did. Hinges and frame come first, hardware second.

Why Does the Strike Plate Decide So Much?

The strike plate is where most residential doors give way. A bolt is only as strong as the wood holding that plate, and the 3/4-inch screws in the box bite into jamb trim rather than framing.

Swapping them for 3-inch screws carries the load into the structure of the house. Reinforced plates spread that force across a wider span of jamb. Both upgrades cost very little, and both get skipped almost every time.

Where Does Handyman Work End and a Locksmith Begin?

A good deal of this is ordinary handyman territory. Like-for-like hardware swaps, adding a deadbolt to a door already prepped for one, correcting a sag, and reinforcing strike plates all sit comfortably there. Choosing what goes back on the door is as much a design call as a security one, so door hardware replacement is worth settling before anyone buys parts.

A locksmith belongs on the rest. That means cutting a fresh bore into an unprepped slab, keying several cylinders alike, safes, and commercial-grade hardware. It also means any job where the key history is unknown and the work has to happen today.

Doing the Whole House In One Pass

Scheduling matters more than it looks. One visit that touches every exterior opening costs far less disruption than four separate afternoons, and every key in the building gets accounted for at once.

Write down what was done. Which doors were changed, which were rekeyed alike, how many keys were issued, and to whom. That short list is exactly what you will want two years later when somebody asks whether the shed key still opens the back door.

Frequently Asked Questions

Is Rekeying as Secure as Fitting a Brand New Lock?

Yes, provided the existing lock is sound. Rekeying resets the pin combination, so previous keys stop working entirely. What it cannot do is improve a weak cylinder, a hollow door, or a badly anchored strike plate.

Can Every Exterior Door Run On the Same Key?

Usually. Cylinders sharing a manufacturer and keyway can be keyed alike during either a rekey or a replacement. A house with mixed brands sometimes ends up with one or two exceptions.

What Should Happen After Contractors Finish a Job?

Count the keys issued against the keys returned. If the numbers do not match, rekey. Keypad codes and garage remotes deserve the same treatment on the same day.

What Should Go On a Door With No Deadbolt?

A single-cylinder deadbolt above the existing knob set is the standard answer. Fitting one needs a second bore through the slab and a matching strike in the jamb. On metal and fiberglass slabs, check the manufacturer boring template before any drilling starts.
