TITANKey Duplication in Naperville and the Chicagoland Suburbs
Spare keys for homes, businesses and many vehicles, cut accurately so they work the first time.
A badly cut copy that sticks in the lock is almost worse than no spare at all. We cut keys accurately so your copies turn smoothly and don't wear your locks, and our service vehicles let us cut many keys on site.
Residential keys
Get spares for family members, roommates or a trusted neighbor, or keys cut to code when an original is too worn to copy.
Commercial keys
We cut extra keys for new staff, keys for master key systems, and restricted keys that can't be copied at a hardware store. Keys stamped Do Not Duplicate are only copied with authorization from the property owner or manager.
Car keys
We duplicate keys for many vehicles. Keys with transponder chips also need programming, which we can do on site for many models. See automotive locksmith.

Common questions
Can you copy a worn-out key?
If a key is very worn, copying it copies the wear too. Where possible, we can cut a new key to the original code instead.
Can you cut keys marked Do Not Duplicate?
That stamp is a request, not a technical barrier, but we treat it seriously and will ask for authorization from the property owner or manager before copying.
Do you duplicate car keys?
Yes, for many vehicles. Keys with chips also need programming, which we can do on site for many models.
