What Drives the Cost of Door Lock or Deadbolt Replacement in Duluth and Superior?
The range is for labor on one door, and the lock is bought separately. Whether the new lock fits, and whether rekeying would do instead, is checked on the visit, and the written quote shows what each door needs.
Does the new lock fit the door? A replacement lock has to match the existing holes in the door and the edge of the frame. A same-size swap is the quickest. If the bore, the latch hole or the strike plate doesn't line up, the door or frame is adjusted, which takes longer. Send the brand and model of what you bought, or a link. Manufacturers such as Schlage publish installation manuals and door-prep templates for each lock.
Door and frame condition. A door that has sagged or a latch that no longer meets its strike makes any lock stick. Adjusting hinges and re-aligning the strike is door repair, quoted with the lock so the new hardware actually closes smoothly.
Keyed-alike sets. If you want one key for the front, back and garage entry doors, buy locks sold as a matching set, or ask us to rekey so they match. Mixing brands makes this harder, and the quote should say how many keys come with each lock. Tell us if any door is a storm door with its own latch, because that hardware is separate from the entry lock.
Number of doors. The planning range is per door. A house with two or three exterior doors costs more in total, but setup is shared across one visit.
Replace the Lock or Rekey It?
Replacing the lock and rekeying the existing one are different jobs. Rekeying changes which key works and keeps the hardware you have. Replacement swaps the hardware itself. Rekeying is worth asking about when the lock is in good shape and only the keys are the problem, and we assess which option suits each door before pricing.
Keep in mind that a lock set is only as secure as the door and frame around it. A worn-out lock on a rotted jamb is a frame problem, and a new exterior door is a different project with its own permit rules. Our window and door replacement cost guide covers door installation.
Move-In Lock Changes and Rentals
Changing the locks soon after you get the keys is a sensible first job in a new house, since you can't know who else holds a copy of the old ones. All exterior locks are swapped or rekeyed and can be keyed alike, so one key opens every door.
Landlords use the same visit between tenants. Multiple doors in one trip are priced as a flat written quote, and a half-day list visit can bundle lock changes with other turnover repairs.
Smart Locks and Keypad Deadbolts
We install smart locks, which give codes to family members and logs for landlords. The planning range above is for lock or deadbolt replacement, and a smart lock's price depends on the product, so tell us the exact model. Check whether it needs batteries or Wi-Fi, and whether it fits your door. We confirm compatibility before the visit, then mount, connect and test it with your family.
A smart lock that is wired or tied to a thermostat or doorbell system is a different scope. Wiring beyond the lock itself is done by a licensed electrician under an electrical permit.
How Can You Keep the Cost of Door Lock or Deadbolt Replacement Down?
Buy locks in matching sets so one key opens every door. Photograph each door, the lock and the edge of the frame. Group lock changes with any door adjustment so they happen in one visit. See our doors and windows page, the handyman cost page, pricing, and Duluth and Superior coverage.
Text photos and a short description to (715) 919-7956, or ask for a written quote; the $95 fee for a visit is waived once you approve the work.

Common Questions
Is the lock included in the replacement price?
No. The $95–$220 planning range covers the labor to replace the lock on one door, and the lock itself is bought separately. If the new lock doesn't match the existing holes, door or frame adjustments add to the scope. The flat price in writing lists installation and any adjustment as separate lines before work starts.
Should I change the locks when I buy a house?
Yes, it is a sensible step, since you can't know who still holds a copy of the old keys. Exterior locks can be swapped or rekeyed and keyed alike, so one key works every door. We assess each door, tell you whether rekeying or replacement fits, and give a written price first.
Can you install a smart lock on my existing door?
Usually, once we confirm the lock fits your door. Tell us the model, and whether it runs on batteries or needs Wi-Fi. Fit depends on the door's holes and the edge of the frame, so we check before the visit. We mount, connect and test it with your family. Wiring beyond the lock itself goes to a licensed electrician.
Why won't my new deadbolt lock smoothly?
Usually the bolt isn't lining up with the strike plate, often because the door has sagged or the frame has shifted with the seasons. Tightening the hinge screws can lift the door back into place. If the bolt still drags, the strike is re-aligned or the hole is enlarged. Our door repair work covers it, and it's quoted with the lock.
