Master Keys & Lock Cylinders in Baltimore
Too many keys on the ring? Staff who should only open some doors? When we change your cylinders, we can set them up as a master key system: one key opens every door, and each employee's key opens only the doors they need.
When to Do It
Opening a new location, taking over a lease, an employee who left with keys, or just too many different keys to keep track of. Changing cylinders is the right time to set up a master key system.
Locked out of your house? We get you back in fast, without damage. We also rekey locks after a move or a lost key, and replace worn or broken locks and deadbolts.
Office or store lockouts, commercial lock changes and rekeys, so only the right people have keys. We work with offices, shops, warehouses and rental properties.
New car keys, key fobs and push-to-start keys, cut and programmed right at your car. Locked out? We open your car without scratches, 24 hours a day.

How a Master Key System Works
Master Key
The owner or manager opens every door with one key.
Sub-Master Keys
A supervisor's key opens one area or one floor, and nothing else.
Individual Keys
Each employee's key opens only the doors they need.
Planned With You
We plan the system with you, then install the new cylinders and cut the keys on site.
