Key Duplication in Northwest Indiana

Having a spare key is one of the simplest ways to avoid a lockout. Keys4U cuts spare keys at our shop in Highland and carries key-cutting equipment in our service vans for on-site duplication across Lake, Porter, and LaPorte counties. Our insured technicians cut keys to manufacturer specifications so spares work as reliably as the original.

What we handle

  • House and residential keys: Duplicate any standard single- or double-sided house key quickly and accurately.
  • Padlock and gate keys: Copy keys for padlocks, shed locks, garage side doors, and fence gates.
  • Office and cabinet keys: Duplicate filing cabinet, desk, and interior door keys for offices and businesses.
  • Basic car keys: Cut a metal blade copy of a standard (non-chip) car key for use as a spare or emergency backup.
  • Mailbox keys: Duplicate small USPS-style or apartment mailbox keys.

Walk-in versus mobile duplication

The fastest option for key cutting is stopping by our shop at 2134 45th St, Highland, IN, where we have the full range of key blanks on hand. For customers who cannot come to us, our mobile technicians carry a selection of the most common blanks and can cut spares during a scheduled service call at your home or business.

Not every key can be duplicated on-site. High-security patented blanks, transponder car keys, and proximity fobs involve additional steps and are priced separately.

Stop in or call Keys4U at (219) 309-3988, open daily from 7:00 AM to 10:00 PM.

Frequently asked questions

Can you duplicate a key marked 'Do Not Duplicate'? +

That marking is a deterrent, not a legal restriction, in Indiana. However, restricted key systems from brands like Medeco or Schlage Everest are patented and cannot be duplicated without authorization from the key holder on file. We will let you know if your key falls into this category.

What types of keys can you duplicate? +

We duplicate standard house keys, padlock keys, office and cabinet keys, and basic car keys. Transponder chip keys and proximity fobs require programming in addition to cutting and are handled as automotive key services.

How long does key cutting take? +

A standard key is cut in a few minutes. If you stop by the shop at 2134 45th St in Highland, you typically wait less than 10 minutes for basic house or office keys.
