Always rekey after a tenant moves out, so lost or unreturned keys can't be used to get back in. We offer full rekeying, on site or off site.
Our locksmiths have seen many cases where standard keys were copied again and again. High security restricted keys can't be duplicated without authorization, so you control how many keys exist for your building.
A master key system gives authorized staff one key for every door, while tenants can open only their own unit and shared areas like the laundry room. It also makes emergencies easier to handle. We've designed many of these systems and can build one for your property.
If your building has one or two main entrances, keeping the automatic door closers on those doors in good shape is important. Heavy daily use wears them out, and we service and replace them.
Mailbox keys are hard to keep track of in multi-unit buildings, which can lead to mail theft or tenants who cannot open their mailboxes. We rekey and replace mailbox locks.
When tenants move out, we can reprogram your garage door openers and remotes. Securing the doors, controlling keys, and covering other entry points like garages and mailboxes all work together to keep your property and tenants safe. Not sure where to start? We offer free security surveys to point out areas of concern.
We're in the business of helping people. We just happen to know a lot about locks, keys and safes.
From commercial locks and access control to replacing lost car keys, plus home locks and emergency service, our family-owned team serves Sun Prairie, Madison, Stoughton and South Central Wisconsin.
