What we do

Locksmith services

Mobile service at your door. Most jobs are finished in one visit, with the parts already on the truck.

Lockouts

Locked out of your home, business or vehicle? We get you back in without damage, anywhere in Door County.

Rekeying

New home, new tenant or a lost key? We change the lock so old keys stop working and hand you new ones. It costs less than new locks.

Lock repair and replacement

Sticking latches, worn deadbolts, broken handles and patio door locks. We repair what can be saved and replace what can't.

Deadbolts and keypad locks

New deadbolts, keypad and smart locks installed and set up, with every door on one key if you want it that way.

Commercial hardware

Push bars and exit devices, storefront locks, door closers and interchangeable cores for shops, resorts and offices.

Rentals and vacation homes

Turnover rekeys, lost-key fixes and hardware that keeps guests from locking themselves out. Work can be done while you're away.

Home and property services

For homeowners who aren't here all year, and for the small jobs that never make it to the top of the list.

Winter and off-season home checks

Regular walk-throughs while you're away: heat on, no leaks, doors and windows secure, and a call if something looks wrong.

Handyman repairs

Doors that stick, trim, storm doors, fixtures and other small repairs, done by the same person who has your keys.

Condos, resorts and businesses

Master key systems, designed and documented

Each owner, guest or employee gets a key that opens only their door. Managers and maintenance carry one key that opens them all. We design the system, build it, and hand you the records so it stays organized for years.

  • Old keys retired at once. A new system ends years of unknown copies.
  • Keys that can't be copied at a hardware store, with removable cores that are swapped in minutes when a key goes missing.
  • Written records for the board. Who has which key, and what each one opens.
  • Pool gates and doors set up to meet Wisconsin's pool barrier rules.

Managing a property?

We work with condo associations, property managers, resorts and inns across the county.

  • Site walk and written proposal
  • Phased installs that fit your season
  • Locks built in the shop, so doors are down for minutes
  • One contact for keys, cores and repairs afterward

Common questions

Good to know

What areas of Door County do you serve?

All of it, from Sturgeon Bay to Gills Rock, including Ellison Bay, Sister Bay, Ephraim, Fish Creek, Egg Harbor, Baileys Harbor and Jacksonport. We're based in Ellison Bay and here year-round.

Can you get me into my car?

Yes. We open locked vehicles without damage. We don't cut or program car keys, remotes or transponder keys.

Should I rekey or replace my locks?

If the locks work well, rekeying is usually the better value. The lock stays on the door, old keys stop working and you get new ones. Replacement makes sense when a lock is worn or damaged, or when you want a different style or a keypad.

Do you come out after hours?

Regular hours are Monday through Saturday, 8 am to 6 pm. For a lockout outside those hours, call or text and we'll come if we can.

What is a master key system?

Each unit or door has its own key, and one master key opens them all. Condo associations, resorts, rental owners and businesses use it so managers and maintenance carry one key while each owner or guest opens only their own door. Every system we build is documented so it can be maintained for years.

How does pricing work?

A flat service charge to come out, plus time and parts. You get the price before the work starts. Payment is by check or Venmo.
