Lock Replacement & Upgrade in Aurora
Every morning the front door key needs the same little dance: push in, lift, wiggle, turn.
In plain words
A replacement lock has to fit holes that already exist, and that is where the visit begins. The locksmith measures the backset, the distance from the door edge to the centre of the bore, which on most doors is 60 or 70 millimetres, checks the cross-bore diameter and edge-bore size, notes door thickness and handing, and looks at the strike cut-out. Most residential hardware is made to these standard preparations, so the new lock usually drops into place with no new drilling. Where a mortise lock or a thick door departs from the norm, filler plates, extension kits or a careful new bore bring the door up to standard.
How the visit goesThe keys the seller handed over came in a sandwich bag: six unlabelled copies for two locks of different makes from different decades. You have no idea how many more copies exist or who is holding them.

How the visit goes
The door and frame around the lock
A new lock inherits whatever the door and frame are doing, so both get a look. The locksmith checks whether the door has dropped on its hinges, whether weatherstrip is pushing it out of square, and whether the bolt lands squarely in the strike pocket or rubs its edge. The pocket depth matters as well: a bolt that reaches the back of a shallow pocket is not fully thrown. Hinge screws, a jamb split from an old forced entry and a strike held by short screws are all noted, because the visit will tidy them up so the new hardware works as designed.
Adapting older and unusual doors
Not every door is a standard modern slab. A century home with a mortise lock may keep its case and get a new cylinder and strike, or take a filler plate that lets a cylindrical deadbolt sit where the old case was, without hacking at the original stile. A door thicker than 45 millimetres gets extended spindles and screws. A sliding patio door gets a replacement mortise hook lock or a keyed surface bolt sized to the rail. Steel and fibreglass doors are drilled only with the right bits and a jig, and a new deadbolt above an existing knob is bored with a template so it sits square.
The rental paperwork, quietly sorted
If the door belongs to a rental unit, the visit finishes with the keys in the right hands. When a landlord orders the change, giving the tenant a full set of new keys is standard practice. When a tenant orders it with the landlord's consent, a key for the landlord is cut alongside the household's and the consent is noted. The locksmith can leave a short written record of the hardware fitted and the keys issued for the property file, so both sides know what is on the door and nobody is surprised at the next inspection or move-out.

What affects the quote
Number of doors
One back door is a small visit; the front, back, side, garage man-door and patio slider together are a longer one, though several doors done at once share the travel and setup.
Special-order hardware
Most standard locks come from the van. A specific style, an unusual finish or a restricted system may need ordering, which affects scheduling and is noted in the quote rather than discovered on the day.
Restricted keyway system
Patented cylinders and controlled key blanks cost more than standard hardware and involve setting up your key records, which is quoted separately from an ordinary replacement.
What to have ready
- Is there a sliding patio door or French door to include?
- Is the door wood, steel or fibreglass, and roughly how thick is it?
- Are you interested in a keypad or smart lock on any door?
Lock Replacement & Upgrade: questions
QuestionsMy deadbolt only locks if I push the door. Will a new lock cure that?
The push is a sign the bolt and the strike pocket are out of line, which is a door and frame matter more than a lock fault. A new deadbolt is welcome if the old one is worn, but the visit also adjusts the strike, deepens the pocket or tightens hinges so the bolt throws freely with the door simply closed. Done together, the door locks with a fingertip and the new hardware works as designed.
Do I have to prove I own the home before you change a lock?
The locksmith will ask, and it is a sign of a careful trade. Photo identification with the address, a deed or property tax notice, or a mortgage or insurance document is plenty for an owner. Tenants show a lease and the landlord's consent; landlords show ownership and confirm the tenant will receive keys. It is a short step that protects everyone with a right to that door.
What information helps before the visit?
Photographs of each lock from outside and inside, plus one of the door edge showing the latch plate and one of the strike on the frame, tell the locksmith most of what they need. Add the door thickness if you can measure it, whether the door is wood, steel or fibreglass, the finish you want to match, how many doors are involved and whether you want them all on one key.
